# Source Map Support
|
||||
[](https://travis-ci.org/evanw/node-source-map-support)
|
||||
|
||||
This module provides source map support for stack traces in node via the [V8 stack trace API](https://github.com/v8/v8/wiki/Stack-Trace-API). It uses the [source-map](https://github.com/mozilla/source-map) module to replace the paths and line numbers of source-mapped files with their original paths and line numbers. The output mimics node's stack trace format with the goal of making every compile-to-JS language more of a first-class citizen. Source maps are completely general (not specific to any one language) so you can use source maps with multiple compile-to-JS languages in the same node process.
|
||||
|
||||
## Installation and Usage
|
||||
|
||||
#### Node support
|
||||
|
||||
```
|
||||
$ npm install source-map-support
|
||||
```
|
||||
|
||||
Source maps can be generated using libraries such as [source-map-index-generator](https://github.com/twolfson/source-map-index-generator). Once you have a valid source map, place a source mapping comment somewhere in the file (usually done automatically or with an option by your transpiler):
|
||||
|
||||
```
|
||||
//# sourceMappingURL=path/to/source.map
|
||||
```
|
||||
|
||||
If multiple sourceMappingURL comments exist in one file, the last sourceMappingURL comment will be
|
||||
respected (e.g. if a file mentions the comment in code, or went through multiple transpilers).
|
||||
The path should either be absolute or relative to the compiled file.
|
||||
|
||||
From here you have two options.
|
||||
|
||||
##### CLI Usage
|
||||
|
||||
```bash
|
||||
node -r source-map-support/register compiled.js
|
||||
```
|
||||
|
||||
##### Programmatic Usage
|
||||
|
||||
Put the following line at the top of the compiled file.
|
||||
|
||||
```js
|
||||
require('source-map-support').install();
|
||||
```
|
||||
|
||||
It is also possible to install the source map support directly by
|
||||
requiring the `register` module which can be handy with ES6:
|
||||
|
||||
```js
|
||||
import 'source-map-support/register'
|
||||
|
||||
// Instead of:
|
||||
import sourceMapSupport from 'source-map-support'
|
||||
sourceMapSupport.install()
|
||||
```
|
||||
Note: if you're using babel-register, it includes source-map-support already.
|
||||
|
||||
It is also very useful with Mocha:
|
||||
|
||||
```
|
||||
$ mocha --require source-map-support/register tests/
|
||||
```
|
||||
|
||||
#### Browser support
|
||||
|
||||
This library also works in Chrome. While the DevTools console already supports source maps, the V8 engine doesn't and `Error.prototype.stack` will be incorrect without this library. Everything will just work if you deploy your source files using [browserify](http://browserify.org/). Just make sure to pass the `--debug` flag to the browserify command so your source maps are included in the bundled code.
|
||||
|
||||
This library also works if you use another build process or just include the source files directly. In this case, include the file `browser-source-map-support.js` in your page and call `sourceMapSupport.install()`. It contains the whole library already bundled for the browser using browserify.
|
||||
|
||||
```html
|
||||
<script src="browser-source-map-support.js"></script>
|
||||
<script>sourceMapSupport.install();</script>
|
||||
```
|
||||
|
||||
This library also works if you use AMD (Asynchronous Module Definition), which is used in tools like [RequireJS](http://requirejs.org/). Just list `browser-source-map-support` as a dependency:
|
||||
|
||||
```html
|
||||
<script>
|
||||
define(['browser-source-map-support'], function(sourceMapSupport) {
|
||||
sourceMapSupport.install();
|
||||
});
|
||||
</script>
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
This module installs two things: a change to the `stack` property on `Error` objects and a handler for uncaught exceptions that mimics node's default exception handler (the handler can be seen in the demos below). You may want to disable the handler if you have your own uncaught exception handler. This can be done by passing an argument to the installer:
|
||||
|
||||
```js
|
||||
require('source-map-support').install({
|
||||
handleUncaughtExceptions: false
|
||||
});
|
||||
```
|
||||
|
||||
This module loads source maps from the filesystem by default. You can provide alternate loading behavior through a callback as shown below. For example, [Meteor](https://github.com/meteor) keeps all source maps cached in memory to avoid disk access.
|
||||
|
||||
```js
|
||||
require('source-map-support').install({
|
||||
retrieveSourceMap: function(source) {
|
||||
if (source === 'compiled.js') {
|
||||
return {
|
||||
url: 'original.js',
|
||||
map: fs.readFileSync('compiled.js.map', 'utf8')
|
||||
};
|
||||
}
|
||||
return null;
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
The module will by default assume a browser environment if XMLHttpRequest and window are defined. If either of these do not exist it will instead assume a node environment.
|
||||
In some rare cases, e.g. when running a browser emulation and where both variables are also set, you can explictly specify the environment to be either 'browser' or 'node'.
|
||||
|
||||
```js
|
||||
require('source-map-support').install({
|
||||
environment: 'node'
|
||||
});
|
||||
```
|
||||
|
||||
To support files with inline source maps, the `hookRequire` options can be specified, which will monitor all source files for inline source maps.
|
||||
|
||||
|
||||
```js
|
||||
require('source-map-support').install({
|
||||
hookRequire: true
|
||||
});
|
||||
```
|
||||
|
||||
This monkey patches the `require` module loading chain, so is not enabled by default and is not recommended for any sort of production usage.
|
||||
|
||||
## Demos
|
||||
|
||||
#### Basic Demo
|
||||
|
||||
original.js:
|
||||
|
||||
```js
|
||||
throw new Error('test'); // This is the original code
|
||||
```
|
||||
|
||||
compiled.js:
|
||||
|
||||
```js
|
||||
require('source-map-support').install();
|
||||
|
||||
throw new Error('test'); // This is the compiled code
|
||||
// The next line defines the sourceMapping.
|
||||
//# sourceMappingURL=compiled.js.map
|
||||
```
|
||||
|
||||
compiled.js.map:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": 3,
|
||||
"file": "compiled.js",
|
||||
"sources": ["original.js"],
|
||||
"names": [],
|
||||
"mappings": ";;AAAA,MAAM,IAAI"
|
||||
}
|
||||
```
|
||||
|
||||
Run compiled.js using node (notice how the stack trace uses original.js instead of compiled.js):
|
||||
|
||||
```
|
||||
$ node compiled.js
|
||||
|
||||
original.js:1
|
||||
throw new Error('test'); // This is the original code
|
||||
^
|
||||
Error: test
|
||||
at Object.<anonymous> (original.js:1:7)
|
||||
at Module._compile (module.js:456:26)
|
||||
at Object.Module._extensions..js (module.js:474:10)
|
||||
at Module.load (module.js:356:32)
|
||||
at Function.Module._load (module.js:312:12)
|
||||
at Function.Module.runMain (module.js:497:10)
|
||||
at startup (node.js:119:16)
|
||||
at node.js:901:3
|
||||
```
|
||||
|
||||
#### TypeScript Demo
|
||||
|
||||
demo.ts:
|
||||
|
||||
```typescript
|
||||
declare function require(name: string);
|
||||
require('source-map-support').install();
|
||||
class Foo {
|
||||
constructor() { this.bar(); }
|
||||
bar() { throw new Error('this is a demo'); }
|
||||
}
|
||||
new Foo();
|
||||
```
|
||||
|
||||
Compile and run the file using the TypeScript compiler from the terminal:
|
||||
|
||||
```
|
||||
$ npm install source-map-support typescript
|
||||
$ node_modules/typescript/bin/tsc -sourcemap demo.ts
|
||||
$ node demo.js
|
||||
|
||||
demo.ts:5
|
||||
bar() { throw new Error('this is a demo'); }
|
||||
^
|
||||
Error: this is a demo
|
||||
at Foo.bar (demo.ts:5:17)
|
||||
at new Foo (demo.ts:4:24)
|
||||
at Object.<anonymous> (demo.ts:7:1)
|
||||
at Module._compile (module.js:456:26)
|
||||
at Object.Module._extensions..js (module.js:474:10)
|
||||
at Module.load (module.js:356:32)
|
||||
at Function.Module._load (module.js:312:12)
|
||||
at Function.Module.runMain (module.js:497:10)
|
||||
at startup (node.js:119:16)
|
||||
at node.js:901:3
|
||||
```
|
||||
|
||||
There is also the option to use `-r source-map-support/register` with typescript, without the need add the `require('source-map-support').install()` in the code base:
|
||||
|
||||
```
|
||||
$ npm install source-map-support typescript
|
||||
$ node_modules/typescript/bin/tsc -sourcemap demo.ts
|
||||
$ node -r source-map-support/register demo.js
|
||||
|
||||
demo.ts:5
|
||||
bar() { throw new Error('this is a demo'); }
|
||||
^
|
||||
Error: this is a demo
|
||||
at Foo.bar (demo.ts:5:17)
|
||||
at new Foo (demo.ts:4:24)
|
||||
at Object.<anonymous> (demo.ts:7:1)
|
||||
at Module._compile (module.js:456:26)
|
||||
at Object.Module._extensions..js (module.js:474:10)
|
||||
at Module.load (module.js:356:32)
|
||||
at Function.Module._load (module.js:312:12)
|
||||
at Function.Module.runMain (module.js:497:10)
|
||||
at startup (node.js:119:16)
|
||||
at node.js:901:3
|
||||
```
|
||||
|
||||
#### CoffeeScript Demo
|
||||
|
||||
demo.coffee:
|
||||
|
||||
```coffee
|
||||
require('source-map-support').install()
|
||||
foo = ->
|
||||
bar = -> throw new Error 'this is a demo'
|
||||
bar()
|
||||
foo()
|
||||
```
|
||||
|
||||
Compile and run the file using the CoffeeScript compiler from the terminal:
|
||||
|
||||
```sh
|
||||
$ npm install source-map-support coffeescript
|
||||
$ node_modules/.bin/coffee --map --compile demo.coffee
|
||||
$ node demo.js
|
||||
|
||||
demo.coffee:3
|
||||
bar = -> throw new Error 'this is a demo'
|
||||
^
|
||||
Error: this is a demo
|
||||
at bar (demo.coffee:3:22)
|
||||
at foo (demo.coffee:4:3)
|
||||
at Object.<anonymous> (demo.coffee:5:1)
|
||||
at Object.<anonymous> (demo.coffee:1:1)
|
||||
at Module._compile (module.js:456:26)
|
||||
at Object.Module._extensions..js (module.js:474:10)
|
||||
at Module.load (module.js:356:32)
|
||||
at Function.Module._load (module.js:312:12)
|
||||
at Function.Module.runMain (module.js:497:10)
|
||||
at startup (node.js:119:16)
|
||||
```
|
||||
|
||||
## Tests
|
||||
|
||||
This repo contains both automated tests for node and manual tests for the browser. The automated tests can be run using mocha (type `mocha` in the root directory). To run the manual tests:
|
||||
|
||||
* Build the tests using `build.js`
|
||||
* Launch the HTTP server (`npm run serve-tests`) and visit
|
||||
* http://127.0.0.1:1336/amd-test
|
||||
* http://127.0.0.1:1336/browser-test
|
||||
* http://127.0.0.1:1336/browserify-test - **Currently not working** due to a bug with browserify (see [pull request #66](https://github.com/evanw/node-source-map-support/pull/66) for details).
|
||||
* For `header-test`, run `server.js` inside that directory and visit http://127.0.0.1:1337/

# Change Log
|
||||
|
||||
## 0.5.6
|
||||
|
||||
* Fix for regression when people were using numbers as names in source maps. See
|
||||
#236.
|
||||
|
||||
## 0.5.5
|
||||
|
||||
* Fix "regression" of unsupported, implementation behavior that half the world
|
||||
happens to have come to depend on. See #235.
|
||||
|
||||
* Fix regression involving function hoisting in SpiderMonkey. See #233.
|
||||
|
||||
## 0.5.4
|
||||
|
||||
* Large performance improvements to source-map serialization. See #228 and #229.
|
||||
|
||||
## 0.5.3
|
||||
|
||||
* Do not include unnecessary distribution files. See
|
||||
commit ef7006f8d1647e0a83fdc60f04f5a7ca54886f86.
|
||||
|
||||
## 0.5.2
|
||||
|
||||
* Include browser distributions of the library in package.json's `files`. See
|
||||
issue #212.
|
||||
|
||||
## 0.5.1
|
||||
|
||||
* Fix latent bugs in IndexedSourceMapConsumer.prototype._parseMappings. See
|
||||
ff05274becc9e6e1295ed60f3ea090d31d843379.
|
||||
|
||||
## 0.5.0
|
||||
|
||||
* Node 0.8 is no longer supported.
|
||||
|
||||
* Use webpack instead of dryice for bundling.
|
||||
|
||||
* Big speedups serializing source maps. See pull request #203.
|
||||
|
||||
* Fix a bug with `SourceMapConsumer.prototype.sourceContentFor` and sources that
|
||||
explicitly start with the source root. See issue #199.
|
||||
|
||||
## 0.4.4
|
||||
|
||||
* Fix an issue where using a `SourceMapGenerator` after having created a
|
||||
`SourceMapConsumer` from it via `SourceMapConsumer.fromSourceMap` failed. See
|
||||
issue #191.
|
||||
|
||||
* Fix an issue with where `SourceMapGenerator` would mistakenly consider
|
||||
different mappings as duplicates of each other and avoid generating them. See
|
||||
issue #192.
|
||||
|
||||
## 0.4.3
|
||||
|
||||
* A very large number of performance improvements, particularly when parsing
|
||||
source maps. Collectively about 75% of time shaved off of the source map
|
||||
parsing benchmark!
|
||||
|
||||
* Fix a bug in `SourceMapConsumer.prototype.allGeneratedPositionsFor` and fuzzy
|
||||
searching in the presence of a column option. See issue #177.
|
||||
|
||||
* Fix a bug with joining a source and its source root when the source is above
|
||||
the root. See issue #182.
|
||||
|
||||
* Add the `SourceMapConsumer.prototype.hasContentsOfAllSources` method to
|
||||
determine when all sources' contents are inlined into the source map. See
|
||||
issue #190.
|
||||
|
||||
## 0.4.2
|
||||
|
||||
* Add an `.npmignore` file so that the benchmarks aren't pulled down by
|
||||
dependent projects. Issue #169.
|
||||
|
||||
* Add an optional `column` argument to
|
||||
`SourceMapConsumer.prototype.allGeneratedPositionsFor` and better handle lines
|
||||
with no mappings. Issues #172 and #173.
|
||||
|
||||
## 0.4.1
|
||||
|
||||
* Fix accidentally defining a global variable. #170.
|
||||
|
||||
## 0.4.0
|
||||
|
||||
* The default direction for fuzzy searching was changed back to its original
|
||||
direction. See #164.
|
||||
|
||||
* There is now a `bias` option you can supply to `SourceMapConsumer` to control
|
||||
the fuzzy searching direction. See #167.
|
||||
|
||||
* About an 8% speed up in parsing source maps. See #159.
|
||||
|
||||
* Added a benchmark for parsing and generating source maps.
|
||||
|
||||
## 0.3.0
|
||||
|
||||
* Change the default direction that searching for positions fuzzes when there is
|
||||
not an exact match. See #154.
|
||||
|
||||
* Support for environments using json2.js for JSON serialization. See #156.
|
||||
|
||||
## 0.2.0
|
||||
|
||||
* Support for consuming "indexed" source maps which do not have any remote
|
||||
sections. See pull request #127. This introduces a minor backwards
|
||||
incompatibility if you are monkey patching `SourceMapConsumer.prototype`
|
||||
methods.
|
||||
|
||||
## 0.1.43
|
||||
|
||||
* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
|
||||
#148 for some discussion and issues #150, #151, and #152 for implementations.
|
||||
|
||||
## 0.1.42
|
||||
|
||||
* Fix an issue where `SourceNode`s from different versions of the source-map
|
||||
library couldn't be used in conjunction with each other. See issue #142.
|
||||
|
||||
## 0.1.41
|
||||
|
||||
* Fix a bug with getting the source content of relative sources with a "./"
|
||||
prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
|
||||
|
||||
* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
|
||||
column span of each mapping.
|
||||
|
||||
* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
|
||||
all generated positions associated with a given original source and line.
|
||||
|
||||
## 0.1.40
|
||||
|
||||
* Performance improvements for parsing source maps in SourceMapConsumer.
|
||||
|
||||
## 0.1.39
|
||||
|
||||
* Fix a bug where setting a source's contents to null before any source content
|
||||
had been set before threw a TypeError. See issue #131.
|
||||
|
||||
## 0.1.38
|
||||
|
||||
* Fix a bug where finding relative paths from an empty path were creating
|
||||
absolute paths. See issue #129.
|
||||
|
||||
## 0.1.37
|
||||
|
||||
* Fix a bug where if the source root was an empty string, relative source paths
|
||||
would turn into absolute source paths. Issue #124.
|
||||
|
||||
## 0.1.36
|
||||
|
||||
* Allow the `names` mapping property to be an empty string. Issue #121.
|
||||
|
||||
## 0.1.35
|
||||
|
||||
* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
|
||||
to specify a path that relative sources in the second parameter should be
|
||||
relative to. Issue #105.
|
||||
|
||||
* If no file property is given to a `SourceMapGenerator`, then the resulting
|
||||
source map will no longer have a `null` file property. The property will
|
||||
simply not exist. Issue #104.
|
||||
|
||||
* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
|
||||
Issue #116.
|
||||
|
||||
## 0.1.34
|
||||
|
||||
* Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
|
||||
|
||||
* Fix bug involving source contents and the
|
||||
`SourceMapGenerator.prototype.applySourceMap`. Issue #100.
|
||||
|
||||
## 0.1.33
|
||||
|
||||
* Fix some edge cases surrounding path joining and URL resolution.
|
||||
|
||||
* Add a third parameter for relative path to
|
||||
`SourceMapGenerator.prototype.applySourceMap`.
|
||||
|
||||
* Fix issues with mappings and EOLs.
|
||||
|
||||
## 0.1.32
|
||||
|
||||
* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
|
||||
(issue 92).
|
||||
|
||||
* Fixed test runner to actually report number of failed tests as its process
|
||||
exit code.
|
||||

## Examples
|
||||
|
||||
### Consuming a source map
|
||||
|
||||
```js
|
||||
var rawSourceMap = {
|
||||
version: 3,
|
||||
file: 'min.js',
|
||||
names: ['bar', 'baz', 'n'],
|
||||
sources: ['one.js', 'two.js'],
|
||||
sourceRoot: 'http://example.com/www/js/',
|
||||
mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
|
||||
};
|
||||
|
||||
var smc = new SourceMapConsumer(rawSourceMap);
|
||||
|
||||
console.log(smc.sources);
|
||||
// [ 'http://example.com/www/js/one.js',
|
||||
// 'http://example.com/www/js/two.js' ]
|
||||
|
||||
console.log(smc.originalPositionFor({
|
||||
line: 2,
|
||||
column: 28
|
||||
}));
|
||||
// { source: 'http://example.com/www/js/two.js',
|
||||
// line: 2,
|
||||
// column: 10,
|
||||
// name: 'n' }

||||
|
||||
console.log(smc.generatedPositionFor({

||||
source: 'http://example.com/www/js/two.js',
|
||||
line: 2,
|
||||
column: 10
|
||||
}));
|
||||
// { line: 2, column: 28 }
|
||||
|
||||
smc.eachMapping(function (m) {
|
||||
// ...
|
||||
});
|
||||
```

||||
|
||||
### Generating a source map
|
||||
|
||||
In depth guide:
|
||||
[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
|
||||
|
||||
#### With SourceNode (high level API)
|
||||
|
||||
```js
|
||||
function compile(ast) {
|
||||
switch (ast.type) {
|
||||
case 'BinaryExpression':
|
||||
return new SourceNode(
|
||||
ast.location.line,
|
||||
ast.location.column,
|
||||
ast.location.source,
|
||||
[compile(ast.left), " + ", compile(ast.right)]
|
||||
);
|
||||
case 'Literal':
|
||||
return new SourceNode(
|
||||
ast.location.line,
|
||||
ast.location.column,
|
||||
ast.location.source,
|
||||
String(ast.value)
|
||||
);
|
||||
// ...
|
||||
default:
|
||||
throw new Error("Bad AST");
|
||||
}
|
||||
}
|
||||
|
||||
var ast = parse("40 + 2", "add.js");
|
||||
console.log(compile(ast).toStringWithSourceMap({
|
||||
file: 'add.js'
|
||||
}));
|
||||
// { code: '40 + 2',
|
||||
// map: [object SourceMapGenerator] }
|
||||
```
|
||||
|
||||
#### With SourceMapGenerator (low level API)
|
||||
|
||||
```js
|
||||
var map = new SourceMapGenerator({
|
||||
file: "source-mapped.js"
|
||||
});
|
||||
|
||||
map.addMapping({
|
||||
generated: {
|
||||
line: 10,
|
||||
column: 35
|
||||
},
|
||||
source: "foo.js",
|
||||
original: {
|
||||
line: 33,
|
||||
column: 2
|
||||
},
|
||||
name: "christopher"
|
||||
});
|
||||
|
||||
console.log(map.toString());
|
||||
// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
Get a reference to the module:
|
||||
|
||||
```js
|
||||
// Node.js
|
||||
var sourceMap = require('source-map');
|
||||
|
||||
// Browser builds
|
||||
var sourceMap = window.sourceMap;
|
||||
|
||||
// Inside Firefox
|
||||
const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
|
||||
```
|
||||
|
||||
### SourceMapConsumer
|
||||
|
||||
A SourceMapConsumer instance represents a parsed source map which we can query
|
||||
for information about the original file positions by giving it a file position
|
||||
in the generated source.
|
||||
|
||||
#### new SourceMapConsumer(rawSourceMap)
|
||||
|
||||
The only parameter is the raw source map (either as a string which can be
|
||||
`JSON.parse`'d, or an object). According to the spec, source maps have the
|
||||
following attributes:
|
||||
|
||||
* `version`: Which version of the source map spec this map is following.
|
||||
|
||||
* `sources`: An array of URLs to the original source files.
|
||||
|
||||
* `names`: An array of identifiers which can be referenced by individual
|
||||
mappings.
|
||||
|
||||
* `sourceRoot`: Optional. The URL root from which all sources are relative.
|
||||
|
||||
* `sourcesContent`: Optional. An array of contents of the original source files.
|
||||
|
||||
* `mappings`: A string of base64 VLQs which contain the actual mappings.
|
||||
|
||||
* `file`: Optional. The generated filename this source map is associated with.
|
||||
|
||||
```js
|
||||
var consumer = new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
|
||||
```
|
||||
|
||||
#### SourceMapConsumer.prototype.computeColumnSpans()
|
||||
|
||||
Compute the last column for each generated mapping. The last column is
|
||||
inclusive.
|
||||
|
||||
```js
|
||||
// Before:
|
||||
consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
|
||||
// [ { line: 2,
|
||||
// column: 1 },
|
||||
// { line: 2,
|
||||
// column: 10 },
|
||||
// { line: 2,
|
||||
// column: 20 } ]
|
||||
|
||||
consumer.computeColumnSpans();
|
||||
|
||||
// After:
|
||||
consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
|
||||
// [ { line: 2,
|
||||
// column: 1,
|
||||
// lastColumn: 9 },
|
||||
// { line: 2,
|
||||
// column: 10,
|
||||
// lastColumn: 19 },
|
||||
// { line: 2,
|
||||
// column: 20,
|
||||
// lastColumn: Infinity } ]
|
||||
|
||||
```
|
||||
|
||||
#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
|
||||
|
||||
Returns the original source, line, and column information for the generated
|
||||
source's line and column positions provided. The only argument is an object with
|
||||
the following properties:
|
||||
|
||||
* `line`: The line number in the generated source. Line numbers in
|
||||
this library are 1-based (note that the underlying source map
|
||||
specification uses 0-based line numbers -- this library handles the
|
||||
translation).
|
||||
|
||||
* `column`: The column number in the generated source. Column numbers
|
||||
in this library are 0-based.
|
||||
|
||||
* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
|
||||
`SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
|
||||
element that is smaller than or greater than the one we are searching for,
|
||||
respectively, if the exact element cannot be found. Defaults to
|
||||
`SourceMapConsumer.GREATEST_LOWER_BOUND`.
|
||||
|
||||
and an object is returned with the following properties:
|
||||
|
||||
* `source`: The original source file, or null if this information is not
|
||||
available.
|
||||
|
||||
* `line`: The line number in the original source, or null if this information is
|
||||
not available. The line number is 1-based.
|
||||
|
||||
* `column`: The column number in the original source, or null if this
|
||||
information is not available. The column number is 0-based.
|
||||
|
||||
* `name`: The original identifier, or null if this information is not available.
|
||||
|
||||
```js
|
||||
consumer.originalPositionFor({ line: 2, column: 10 })
|
||||
// { source: 'foo.coffee',
|
||||
// line: 2,
|
||||
// column: 2,
|
||||
// name: null }
|
||||
|
||||
consumer.originalPositionFor({ line: 99999999999999999, column: 999999999999999 })
|
||||
// { source: null,
|
||||
// line: null,
|
||||
// column: null,
|
||||
// name: null }

number is 0-based.
|
||||
|
||||
and an object is returned with the following properties:

|
||||
// { line: 1,
|
||||

|
||||
```
|

|
||||
#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
|
||||
|
||||

column number is 0-based.
|
||||
|
||||
```js
|
||||
consumer.allGeneratedpositionsfor({ line: 2, source: "foo.coffee" })
|
||||
// [ { line: 2,
|
||||
// column: 1 },
|
||||
// { line: 2,
|
||||
// column: 10 },
|
||||
// { line: 2,
|
||||
// column: 20 } ]
|
||||
```
|
||||
|
||||
#### SourceMapConsumer.prototype.hasContentsOfAllSources()
|
||||
|
||||
Return true if we have the embedded source content for every source listed in
|
||||
the source map, false otherwise.
|
||||
|
||||
In other words, if this method returns `true`, then
|
||||
`consumer.sourceContentFor(s)` will succeed for every source `s` in
|
||||
`consumer.sources`.
|
||||
|
||||
```js
|
||||
// ...
|
||||
if (consumer.hasContentsOfAllSources()) {
|
||||
consumerReadyCallback(consumer);
|
||||
} else {
|
||||
fetchSources(consumer, consumerReadyCallback);
|
||||
}
|
||||
// ...
|
||||
```
|
||||
|
||||
#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
|
||||
|
||||
Returns the original source content for the source provided. The only
|
||||
argument is the URL of the original source file.
|
||||
|
||||
If the source content for the given source is not found, then an error is
|
||||
thrown. Optionally, pass `true` as the second param to have `null` returned
|
||||
instead.
|
||||
|
||||
```js
|
||||
consumer.sources
|
||||
// [ "my-cool-lib.clj" ]
|
||||
|
||||
consumer.sourceContentFor("my-cool-lib.clj")
|
||||
// "..."
|
||||
|
||||
consumer.sourceContentFor("this is not in the source map");
|
||||
// Error: "this is not in the source map" is not in the source map
|
||||
|
||||
consumer.sourceContentFor("this is not in the source map", true);
|
||||
// null
|
||||
```
|
||||
|
||||
#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
|
||||
|
||||
Iterate over each mapping between an original source/line/column and a
|
||||
generated line/column in this source map.
|
||||
|
||||
* `callback`: The function that is called with each mapping. Mappings have the
|
||||
form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
|
||||
name }`
|
||||
|
||||
* `context`: Optional. If specified, this object will be the value of `this`
|
||||
every time that `callback` is called.
|
||||
|
||||
* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
|
||||
`SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
|
||||
the mappings sorted by the generated file's line/column order or the
|
||||
original's source/line/column order, respectively. Defaults to
|
||||
`SourceMapConsumer.GENERATED_ORDER`.
|
||||
|
||||
```js
|
||||
consumer.eachMapping(function (m) { console.log(m); })
|
||||
// ...
|
||||
// { source: 'illmatic.js',
|
||||
// generatedLine: 1,
|
||||
// generatedColumn: 0,
|
||||
// originalLine: 1,
|
||||
// originalColumn: 0,
|
||||
// name: null }
|
||||
// { source: 'illmatic.js',
|
||||
// generatedLine: 2,
|
||||
// generatedColumn: 0,
|
||||
// originalLine: 2,
|
||||
// originalColumn: 0,
|
||||
// name: null }
|
||||
// ...
|
||||
```
|
||||
### SourceMapGenerator
|
||||
|
||||
An instance of the SourceMapGenerator represents a source map which is being
|
||||
built incrementally.
|
||||
|
||||
#### new SourceMapGenerator([startOfSourceMap])
|
||||
|
||||
You may pass an object with the following properties:
|
||||
|
||||
* `file`: The filename of the generated source that this source map is
|
||||
associated with.
|
||||
|
||||
* `sourceRoot`: A root for all relative URLs in this source map.
|
||||
|
||||
* `skipValidation`: Optional. When `true`, disables validation of mappings as
|
||||
they are added. This can improve performance but should be used with
|
||||
discretion, as a last resort. Even then, one should avoid using this flag when
|
||||
running tests, if possible.
|
||||
|
||||
```js
|
||||
var generator = new sourceMap.SourceMapGenerator({
|
||||
file: "my-generated-javascript-file.js",
|
||||
sourceRoot: "http://example.com/app/js/"
|
||||
});
|
||||
```
|
||||
|
||||
#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
|
||||
|
||||
Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
|
||||
|
||||
* `sourceMapConsumer` The SourceMap.
|
||||
|
||||
```js
|
||||
var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer);
|
||||
```
|
||||
|
||||
#### SourceMapGenerator.prototype.addMapping(mapping)
|
||||
|
||||
Add a single mapping from original source line and column to the generated
|
||||
source's line and column for this source map being created. The mapping object
|
||||
should have the following properties:
|
||||
|
||||
* `generated`: An object with the generated line and column positions.
|
||||
|
||||
* `original`: An object with the original line and column positions.
|
||||
|
||||
* `source`: The original source file (relative to the sourceRoot).
|
||||
|
||||
* `name`: An optional original token name for this mapping.
|
||||
|
||||
```js
|
||||
generator.addMapping({
|
||||
source: "module-one.scm",
|
||||
original: { line: 128, column: 0 },
|
||||
generated: { line: 3, column: 456 }
|
||||
})
|
||||
```
|
||||
|
||||
#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
|
||||
|
||||
Set the source content for an original source file.
|
||||
|
||||
* `sourceFile` the URL of the original source file.
|
||||
|
||||
* `sourceContent` the content of the source file.
|
||||
|
||||
```js
|
||||
generator.setSourceContent("module-one.scm",
|
||||
fs.readFileSync("path/to/module-one.scm"))
|
||||
```
|
||||
|
||||
#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
|
||||
|
||||
Applies a SourceMap for a source file to the SourceMap.
|
||||
Each mapping to the supplied source file is rewritten using the
|
||||
supplied SourceMap. Note: The resolution for the resulting mappings
|
||||
is the minimum of this map and the supplied map.
|
||||
|
||||
* `sourceMapConsumer`: The SourceMap to be applied.
|
||||
|
||||
* `sourceFile`: Optional. The filename of the source file.
|
||||
If omitted, sourceMapConsumer.file will be used, if it exists.
|
||||
Otherwise an error will be thrown.
|
||||
|
||||
* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
|
||||
to be applied. If relative, it is relative to the SourceMap.
|
||||
|
||||
This parameter is needed when the two SourceMaps aren't in the same
|
||||
directory, and the SourceMap to be applied contains relative source
|
||||
paths. If so, those relative source paths need to be rewritten
|
||||
relative to the SourceMap.
|
||||
|
||||
If omitted, it is assumed that both SourceMaps are in the same directory,
|
||||
thus not needing any rewriting. (Supplying `'.'` has the same effect.)
|
||||
|
||||
#### SourceMapGenerator.prototype.toString()
|
||||
|
||||
Renders the source map being generated to a string.
|
||||
|
||||
```js
|
||||
generator.toString()
|
||||
// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
|
||||
```
|
||||
|
||||
### SourceNode
|
||||
|
||||
SourceNodes provide a way to abstract over interpolating and/or concatenating
|
||||
snippets of generated JavaScript source code, while maintaining the line and
|
||||
column information associated between those snippets and the original source
|
||||
code. This is useful as the final intermediate representation a compiler might
|
||||
use before outputting the generated JS and source map.
|
||||
|
||||
#### new SourceNode([line, column, source[, chunk[, name]]])
|
||||
|
||||
* `line`: The original line number associated with this source node, or null if
|
||||
it isn't associated with an original line. The line number is 1-based.
|
||||
|
||||
* `column`: The original column number associated with this source node, or null
|
||||
if it isn't associated with an original column. The column number
|
||||
is 0-based.
|
||||
|
||||
* `source`: The original source's filename; null if no filename is provided.
|
||||
|
||||
* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
|
||||
below.
|
||||
|
||||
* `name`: Optional. The original identifier.
|
||||
|
||||
```js
|
||||
var node = new SourceNode(1, 2, "a.cpp", [
|
||||
new SourceNode(3, 4, "b.cpp", "extern int status;\n"),
|
||||
new SourceNode(5, 6, "c.cpp", "std::string* make_string(size_t n);\n"),
|
||||
new SourceNode(7, 8, "d.cpp", "int main(int argc, char** argv) {}\n"),
|
||||
]);
|
||||
```
|
||||
|
||||
#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
|
||||
|
||||
Creates a SourceNode from generated code and a SourceMapConsumer.
|
||||
|
||||
* `code`: The generated code
|
||||
|
||||
* `sourceMapConsumer` The SourceMap for the generated code
|
||||
|
||||
* `relativePath` The optional path that relative sources in `sourceMapConsumer`
|
||||
should be relative to.
|
||||
|
||||
```js
|
||||
var consumer = new SourceMapConsumer(fs.readFileSync("path/to/my-file.js.map", "utf8"));
|
||||
var node = SourceNode.fromStringWithSourceMap(fs.readFileSync("path/to/my-file.js"),
|
||||
consumer);
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.add(chunk)
|
||||
|
||||
Add a chunk of generated JS to this source node.
|
||||
|
||||
* `chunk`: A string snippet of generated JS code, another instance of
|
||||
`SourceNode`, or an array where each member is one of those things.
|
||||
|
||||
```js
|
||||
node.add(" + ");
|
||||
node.add(otherNode);
|
||||
node.add([leftHandOperandNode, " + ", rightHandOperandNode]);
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.prepend(chunk)
|
||||
|
||||
Prepend a chunk of generated JS to this source node.
|
||||
|
||||
* `chunk`: A string snippet of generated JS code, another instance of
|
||||
`SourceNode`, or an array where each member is one of those things.
|
||||
|
||||
```js
|
||||
node.prepend("/** Build Id: f783haef86324gf **/\n\n");
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
|
||||
|
||||
Set the source content for a source file. This will be added to the
|
||||
`SourceMap` in the `sourcesContent` field.
|
||||
|
||||
* `sourceFile`: The filename of the source file
|
||||
|
||||
* `sourceContent`: The content of the source file
|
||||
|
||||
```js
|
||||
node.setSourceContent("module-one.scm",
|
||||
fs.readFileSync("path/to/module-one.scm"))
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.walk(fn)
|
||||
|
||||
Walk over the tree of JS snippets in this node and its children. The walking
|
||||
function is called once for each snippet of JS and is passed that snippet and
|
||||
the its original associated source's line/column location.
|
||||
|
||||
* `fn`: The traversal function.
|
||||
|
||||
```js
|
||||
var node = new SourceNode(1, 2, "a.js", [
|
||||
new SourceNode(3, 4, "b.js", "uno"),
|
||||
"dos",
|
||||
[
|
||||
"tres",
|
||||
new SourceNode(5, 6, "c.js", "quatro")
|
||||
]
|
||||
]);
|
||||
|
||||
node.walk(function (code, loc) { console.log("WALK:", code, loc); })
|
||||
// WALK: uno { source: 'b.js', line: 3, column: 4, name: null }
|
||||
// WALK: dos { source: 'a.js', line: 1, column: 2, name: null }
|
||||
// WALK: tres { source: 'a.js', line: 1, column: 2, name: null }
|
||||
// WALK: quatro { source: 'c.js', line: 5, column: 6, name: null }
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.walkSourceContents(fn)
|
||||
|
||||
Walk over the tree of SourceNodes. The walking function is called for each
|
||||
source file content and is passed the filename and source content.
|
||||
|
||||
* `fn`: The traversal function.
|
||||
|
||||
```js
|
||||
var a = new SourceNode(1, 2, "a.js", "generated from a");
|
||||
a.setSourceContent("a.js", "original a");
|
||||
var b = new SourceNode(1, 2, "b.js", "generated from b");
|
||||
b.setSourceContent("b.js", "original b");
|
||||
var c = new SourceNode(1, 2, "c.js", "generated from c");
|
||||
c.setSourceContent("c.js", "original c");
|
||||
|
||||
var node = new SourceNode(null, null, null, [a, b, c]);
|
||||
node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })
|
||||
// WALK: a.js : original a
|
||||
// WALK: b.js : original b
|
||||
// WALK: c.js : original c
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.join(sep)
|
||||
|
||||
Like `Array.prototype.join` except for SourceNodes. Inserts the separator
|
||||
between each of this source node's children.
|
||||
|
||||
* `sep`: The separator.
|
||||
|
||||
```js
|
||||
var lhs = new SourceNode(1, 2, "a.rs", "my_copy");
|
||||
var operand = new SourceNode(3, 4, "a.rs", "=");
|
||||
var rhs = new SourceNode(5, 6, "a.rs", "orig.clone()");
|
||||
|
||||
var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
|
||||
var joinedNode = node.join(" ");
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.replaceRight(pattern, replacement)
|
||||
|
||||
Call `String.prototype.replace` on the very right-most source snippet. Useful
|
||||
for trimming white space from the end of a source node, etc.
|
||||
|
||||
* `pattern`: The pattern to replace.
|
||||
|
||||
* `replacement`: The thing to replace the pattern with.
|
||||
|
||||
```js
|
||||
// Trim trailing white space.
|
||||
node.replaceRight(/\s*$/, "");
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.toString()
|
||||
|
||||
Return the string representation of this source node. Walks over the tree and
|
||||
concatenates all the various snippets together to one string.
|
||||
|
||||
```js
|
||||
var node = new SourceNode(1, 2, "a.js", [
|
||||
new SourceNode(3, 4, "b.js", "uno"),
|
||||
"dos",
|
||||
[
|
||||
"tres",
|
||||
new SourceNode(5, 6, "c.js", "quatro")
|
||||
]
|
||||
]);
|
||||
|
||||
node.toString()
|
||||
// 'unodostresquatro'
|
||||
```
|
||||
|
||||
#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
|
||||
|
||||
Returns the string representation of this tree of source nodes, plus a
|
||||
SourceMapGenerator which contains all the mappings between the generated and
|
||||
original sources.
|
||||
|
||||
The arguments are the same as those to `new SourceMapGenerator`.
|
||||
|
||||
```js
|
||||
var node = new SourceNode(1, 2, "a.js", [
|
||||
new SourceNode(3, 4, "b.js", "uno"),
|
||||
"dos",
|
||||
[
|
||||
"tres",
|
||||
new SourceNode(5, 6, "c.js", "quatro")
|
||||
]
|
||||
]);
|
||||
|
||||
node.toStringWithSourceMap({ file: "my-output-file.js" })
|
||||
// { code: 'unodostresquatro',
|
||||
// map: [object SourceMapGenerator] }
