Broccoli-source-map NPM

broccoli-source-map

A Broccoli plugin for inlining or extracting JavaScript and CSS source maps using convert-source-map.

Installation

$ npm install --save-dev broccoli-source-map

Usage

var sourceMap = require('broccoli-source-map')
var src = 'js_and_maps' // probably something like: sweetjs('js', {sourceMap: true, readableNames: true});
var inlined = new sourceMap.SourceMapInliner([src])
var extracted = new sourceMap.SourceMapExtractor([inlined])

inline

require('broccoli-source-map').SourceMapInliner combines pairs of .js and .js.map (.css and .css.map) files into one .js (.css) file that contains the source map as a base64 URL comment. If the map contains file references in the sources field, but not the sourcesContent field, it will also inline the files into that field to make the compiled file independent of the source file. This is very useful if you want to use broccoli-browserify because browserify reads inline source maps, but not external ones.

extract

require('broccoli-source-map').SourceMapExtractor extracts source maps from base64 URL comments of .js (.css) files into separate .js.map (.css.map) files, just like exorcist.
