Installation
npm install source-map-urlbower install source-map-urlcomponent install lydell/source-map-url
Works with CommonJS, AMD and browser globals, through UMD.
Usage
sourceMappingURL.getFrom(code)
Returns the url of the sourceMappingURL comment in code. Returns null if
there is no such comment.
sourceMappingURL.existsIn(code)
Returns true if there is a sourceMappingURL comment in code, or false
otherwise.
sourceMappingURL.removeFrom(code)
Removes the sourceMappingURL comment in code. Does nothing if there is no
such comment. Returns the updated code.
sourceMappingURL.insertBefore(code, string)
Inserts string before the sourceMappingURL comment in code. Appends
string to code if there is no such comment.
Lets you append something to a file without worrying about burying the sourceMappingURL comment (by keeping it at the end of the file).
sourceMappingURL.regex
The regex that is used to match sourceMappingURL comments. It matches both //
and /**/ comments, thus supporting both JavaScript and CSS.
Tests
Start by running npm test, which lints the code and runs the test suite in Node.js.
To run the tests in a browser, run testling (npm install -g testling) or testling -u.
