Works with CommonJS, AMD and browser globals, through UMD.
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.
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
.
