Steps to reproduce
Steps to reproduce the problem:
- Create a local directory structure like so:
- Open the js file, and ensure it has a sourceMappingUrl directive, pointing to the map file, but also ensure the url has a leading / like so:
- Serve the directory up (browse the index.html page)
What is the expected behavior?
According to the Sourcemap V3 spec:
When the source mapping URL is not absolute, then it is relative to the generated code’s “source origin”.
If the generated code is associated with a script element and the script element has a “src” attribute, the “src” attribute of the script element will be the source origin.
This means I would expect edge to issue a request for the map file on /foo/bar.js.map
What went wrong?
Using fiddler (requests for source map files don’t appear to show up on the network tab) edge makes a request:
GET /foo.js.map HTTP/1.1
The leading “/” in the sourceMappingUrl appears to make edge treat resolve the url to the map file as relative to the site root rather than the source origin…
