exorcist

Externalizes the source map found inside a stream to an external .map file or stream.

Works with both JavaScript and CSS input streams.

var browserify = require('browserify')
  , path       = require('path')
  , fs         = require('fs')
  , exorcist   = require('exorcist')
  , mapfile    = path.join(__dirname, 'bundle.js.map')

// from a file, to a file, and send source map to its own file
browserify({debug: true})
  .require(require.resolve('./main'), { entry: true })
  .bundle()
  .pipe(exorcist(mapfile))
  .pipe(fs.createWriteStream(path.join(__dirname, 'bundle.js'), 'utf8'))

//  from a stream, to a stream, and send source map to a stream
browserify([readableSourceStream], browserifyOptions)
  .bundle()
  .pipe(exorcist(targetSourceMapStream, '/url/path/to/replace/source/comment/with/bundle.js'))
  .pipe(writableTargetStream)

command line example

browserify main.js --debug | exorcist bundle.js.map &gt; bundle.js

Usage

exorcist map_file [options]

  Externalizes the source map of the file streamed in.

  The source map is written as JSON to map_file, and the original file is streamed out with its
  sourceMappingURL set to the path of map_file (or to the value of the --url option).

OPTIONS:

              --base -b   Base path for calculating relative source paths.
                          (default: use absolute paths)

              --root -r   Root URL for loading relative source paths.
                          Set as sourceRoot in the source map.
                          (default: '')

               --url -u   Full URL to source map.
                          Set as sourceMappingURL in the output stream.
                          (default: map_file)

  --error-on-missing -e   Abort with error if no map is found in the stream.
                          (default: warn but still pipe through source)

EXAMPLE:

  Bundle main.js with browserify into bundle.js and externalize the map to bundle.js.map.

    browserify main.js --debug | exorcist bundle.js.map &gt; bundle.js

Installation

npm install exorcist

API

exorcist(input, url, root, base, errorOnMissing) → {TransformStream}

Externalizes the source map of the file streamed in.

The source map is written as JSON to file, and the original file is streamed out with its sourceMappingURL set to the path of file (or to the value of url).

Events (in addition to stream events)

missing-map emitted if no map was found in the stream and errorOnMissing is falsey (the src is still piped through in this case, but no map file is written)

Parameters:

Name	Type	Argument	Description
`input`	String / Object		full path to the map file to which to write the extracted source map or a writable stream
`url`	String	<optional>	full URL to the map file, set as `sourceMappingURL` in the streaming output (default: file)
`root`	String	<optional>	root URL for loading relative source paths, set as `sourceRoot` in the source map (default: '')
`base`	String	<optional>	base path for calculating relative source paths (default: use absolute paths)
`errorOnMissing`	Boolean	<optional>	when truthy, causes 'error' to be emitted instead of 'missing-map' if no map was found in the stream (default: falsey)

Source:

index.js , lineno 33

Returns:

transform stream into which to pipe the code containing the source map

Type: TransformStream
