# gulp-sourcemaps
[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Travis Build Status][travis-image]][travis-url] [![AppVeyor Build Status][appveyor-image]][appveyor-url] [![Coveralls Status][coveralls-image]][coveralls-url]
Sourcemap support for gulpjs.
### Usage
All the examples here works with Gulp 4. To see examples related to Gulp 3, [you can read them here](https://github.com/gulp-sourcemaps/gulp-sourcemaps/blob/v2.6.5/README.md).
#### Write inline source maps
Inline source maps are embedded in the source file.
Example:
```javascript
var gulp = require('gulp');
var plugin1 = require('gulp-plugin1');
var plugin2 = require('gulp-plugin2');
var sourcemaps = require('gulp-sourcemaps');
function javascript() {
gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write())
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
All plugins between `sourcemaps.init()` and `sourcemaps.write()` need to have support for `gulp-sourcemaps`. You can find a list of such plugins in the [wiki](https://github.com/gulp-sourcemaps/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support).
#### Write external source map files
To write external source map files, pass a path relative to the destination to `sourcemaps.write()`.
Example:
```javascript
var gulp = require('gulp');
var plugin1 = require('gulp-plugin1');
var plugin2 = require('gulp-plugin2');
var sourcemaps = require('gulp-sourcemaps');
function javascript() {
gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
#### Load existing source maps
To load existing source maps, pass the option `loadMaps: true` to `sourcemaps.init()`.
Example:
```javascript
var gulp = require('gulp');
var plugin1 = require('gulp-plugin1');
var plugin2 = require('gulp-plugin2');
var sourcemaps = require('gulp-sourcemaps');
function javascript() {
gulp.src('src/**/*.js')
.pipe(sourcemaps.init({loadMaps: true}))
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write())
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
#### Handle large files
To handle large files, pass the option `largeFile: true` to `sourcemaps.init()`.
Example:
```javascript
var gulp = require('gulp');
var plugin1 = require('gulp-plugin1');
var plugin2 = require('gulp-plugin2');
var sourcemaps = require('gulp-sourcemaps');
function javascript() {
gulp.src('src/**/*.js')
.pipe(sourcemaps.init({largeFile: true}))
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write())
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
#### Handle source files from different directories
Use the `base` option on `gulp.src` to make sure all files are relative to a common base directory.
Example:
```javascript
var gulp = require('gulp');
var plugin1 = require('gulp-plugin1');
var plugin2 = require('gulp-plugin2');
var sourcemaps = require('gulp-sourcemaps');
function javascript() {
gulp.src(['src/test.js', 'src/testdir/test2.js'], { base: 'src' })
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
#### Alter `sources` property on sourcemaps
The exported `mapSources` method gives full control over the source paths. It takes a function that is called for every source and receives the default source path as a parameter and the original vinyl file.
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
// be careful with the sources returned otherwise contents might not be loaded properly
.pipe(sourcemaps.mapSources(function(sourcePath, file) {
// source paths are prefixed with '../src/'
return '../src/' + sourcePath;
}))
.pipe(sourcemaps.write('../maps')
.pipe(gulp.dest('public/scripts'));
};
exports.javascript = javascript;
```
#### Generate Identity Sourcemap
The exported `identityMap` method allows you to generate a full valid source map encoding no changes (slower, only for Javascript and CSS) instead of the default empty source map (no mappings, fast). __Use this option if you get missing or incorrect mappings, e.g. when debugging.__
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
// An identity sourcemap will be generated at this step
.pipe(sourcemaps.identityMap())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps')
.pipe(gulp.dest('public/scripts'));
};
exports.javascript = javascript;
```
### Init Options
- `loadMaps`
Set to true to load existing maps for source files. Supports the following:
- inline source maps
- source map files referenced by a `sourceMappingURL=` comment
- source map files with the same name (plus .map) in the same directory
- `identityMap`
__This option is deprecated. Upgrade to use our [`sourcemap.identityMap`](#generate-identity-sourcemap) API.__
### Write Options
- `addComment`
By default a comment containing / referencing the source map is added. Set this to `false` to disable the comment (e.g. if you want to load the source maps by header).
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps', {addComment: false}))
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
- `includeContent`
By default the source maps include the source code. Pass `false` to use the original files.
Including the content is the recommended way, because it "just works". When setting this to `false` you have to host the source files and set the correct `sourceRoot`.
- `sourceRoot`
Set the location where the source files are hosted (use this when `includeContent` is set to `false`). This is usually a URL (or an absolute URL path), not a local file system path.
By default the source root is '' or in case `destPath` is set, the relative path from the source map to the source base directory (this should work for many dev environments).
If a relative path is used (empty string or one starting with a `.`), it is interpreted as a path relative to the destination. The plugin rewrites it to a path relative to each source map.
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write({includeContent: false, sourceRoot: '/src'}))
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
Example (using a function):
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write({
includeContent: false,
sourceRoot: function(file) {
return '/src';
}
}))
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
Example (relative path):
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('.', {includeContent: false, sourceRoot: '../src'}))
.pipe(gulp.dest('dist'));
};
exports.javascript = javascript;
```
In this case for a file written to `dist/subdir/example.js`, the source map is written to `dist/subdir/example.js.map` and the sourceRoot will be `../../src` (resulting in the full source path `../../src/subdir/example.js`).
- `destPath`
Set the destination path (the same you pass to `gulp.dest()`). If the source map destination path is not a sub path of the destination path, this is needed to get the correct path in the `file` property of the source map.
In addition, it allows to automatically set a relative `sourceRoot` if none is set explicitly.
- `sourceMappingURLPrefix`
Specify a prefix to be prepended onto the source map URL when writing external source maps. Relative paths will have their leading dots stripped.
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps', {
sourceMappingURLPrefix: 'https://asset-host.example.com/assets'
}))
.pipe(gulp.dest('public/scripts'));
};
exports.javascript = javascript;
```
This will result in a source mapping URL comment like `sourceMappingURL=https://asset-host.example.com/assets/maps/helloworld.js.map`.
- `sourceMappingURL`
If you need full control over the source map URL you can pass a function to this option. The output of the function must be the full URL to the source map (in function of the output file).
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps', {
sourceMappingURL: function(file) {
return 'https://asset-host.example.com/' + file.relative + '.map';
}
}))
.pipe(gulp.dest('public/scripts'));
};
exports.javascript = javascript;
```
This will result in a source mapping URL comment like `sourceMappingURL=https://asset-host.example.com/helloworld.js.map`.
- `mapFile`
This option allows to rename the map file. It takes a function that is called for every map and receives the default map path as a parameter.
Example:
```javascript
function javascript() {
var stream = gulp.src('src/**/*.js')
.pipe(sourcemaps.init())
.pipe(plugin1())
.pipe(plugin2())
.pipe(sourcemaps.write('../maps', {
mapFile: function(mapFilePath) {
// source map files are named *.map instead of *.js.map
return mapFilePath.replace('.js.map', '.map');
}
}))
.pipe(gulp.dest('public/scripts'));
};
exports.javascript = javascript;
```
- `mapSources`
__This option is deprecated. Upgrade to use our [`sourcemap.mapSources`](#alter-sources-property-on-sourcemaps) API.__
- `charset`
Sets the charset for inline source maps. Default: `utf8`
- `clone`
Clones the original file for creation of the map file. Could be important if file history is important. See [file.clone()](https://github.com/gulpjs/vinyl#filecloneoptions) for possible options. Default: `{deep:false, contents:false}`
### Plugin developers only:
- **How to add source map support to plugins**
- Generate a source map for the transformation the plugin is applying
- **Important**: Make sure the paths in the generated source map (`file` and `sources`) are relative to `file.base` (e.g. use `file.relative`).
- Apply this source map to the vinyl `file`. E.g. by using [vinyl-sourcemaps-apply](https://github.com/gulp-sourcemaps/vinyl-sourcemaps-apply).
This combines the source map of this plugin with the source maps coming from plugins further up the chain.
- Add your plugin to the [wiki page](https://github.com/gulp-sourcemaps/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support)
#### Example:
```js
var through = require('through2');
var applySourceMap = require('vinyl-sourcemaps-apply');
var myTransform = require('myTransform');
module.exports = function(options) {
function transform(file, encoding, callback) {
// generate source maps if plugin source-map present
if (file.sourceMap) {
options.makeSourceMaps = true;
}
// do normal plugin logic
var result = myTransform(file.contents, options);
file.contents = new Buffer(result.code);
// apply source map to the chain
if (file.sourceMap) {
applySourceMap(file, result.map);
}
this.push(file);
callback();
}
return through.obj(transform);
};
```
- **Verify sourcemaps are working**
See example below or refer to [test/write.js](./test/write.js)
#### Example:
```js
var stream = plugin();
var init = sourcemaps.init();
var write = sourcemaps.write();
init.pipe(stream).pipe(write);
write.on('data', function (file) {
assert(...);
cb();
});
init.write(new gutil.File(...));
init.end();
```
### Debugging
All debugging output relies on [visionmedia/debug](https://github.com/visionmedia/debug). Follow the directions to set the
environment variable `$DEBUG`.
For a few examples of debug you could use:
```sh
DEBUG='gulp-sourcemaps:*' #everything
DEBUG='gulp-sourcemaps:init' #init/index.js
DEBUG='gulp-sourcemaps:init:*' #init/index.internals.js
DEBUG='gulp-sourcemaps:write:' #write/index.js
DEBUG='gulp-sourcemaps:write:*' #write/index.internals.js
DEBUG='gulp-sourcemaps:write:,gulp-sourcemaps:init:**' #write/index.internals.js and init/index.internals.js

# through2
[![NPM](https://nodei.co/npm/through2.png?downloads&downloadRank)](https://nodei.co/npm/through2/)
**A tiny wrapper around Node streams.Transform (Streams2/3) to avoid explicit subclassing noise**
Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
Note: As 2.x.x this module starts using **Streams3** instead of Stream2. To continue using a Streams2 version use `npm install through2@0` to fetch the latest version of 0.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
```js
fs.createReadStream('ex.txt')
.pipe(through2(function (chunk, enc, callback) {
for (var i = 0; i < chunk.length; i++)
if (chunk[i] == 97)
chunk[i] = 122 // swap 'a' for 'z'
this.push(chunk)
callback()
}))
.pipe(fs.createWriteStream('out.txt'))
.on('finish', () => doSomethingSpecial())
```
Or object streams:
```js
var all = []
fs.createReadStream('data.csv')
.pipe(csv2())
.pipe(through2.obj(function (chunk, enc, callback) {
var data = {
name : chunk[0]
, address : chunk[3]
, phone : chunk[10]
}
this.push(data)
callback()
}))
.on('data', (data) => {
all.push(data)
})
.on('end', () => {
doSomethingSpecial(all)
})
```
Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
## API
<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
### options
The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
```js
fs.createReadStream('/tmp/important.dat')
.pipe(through2({ objectMode: true, allowHalfOpen: false },
(chunk, enc, cb) => {
cb(null, 'wut?') // note we can use the second argument on the callback
// to provide data as an alternative to this.push('wut?')
}
)
.pipe(fs.createWriteStream('/tmp/wut.txt'))
```
### transformFunction
The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
### flushFunction
The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
```js
fs.createReadStream('/tmp/important.dat')
.pipe(through2(
(chunk, enc, cb) => cb(null, chunk), // transform is a noop
function (cb) { // flush function
this.push('tacking on an extra buffer to the end');
cb();
}
))
.pipe(fs.createWriteStream('/tmp/wut.txt'));
```
<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
```js
var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
if (record.temp != null && record.unit == "F") {
record.temp = ( ( record.temp - 32 ) * 5 ) / 9
record.unit = "C"
}
this.push(record)
callback()
})
// Create instances of FToC like so:
var converter = new FToC()
// Or:
var converter = FToC()
// Or specify/override options when you instantiate, if you prefer:
var converter = FToC({objectMode: true})
```
