SourceMap Header Is Ignored On Different Host

- 1 answer

If I'm serving bundle.js from http://localhost:5000 with the SourceMap: /bundle.js.map it works fine, however when I include <script src="http://localhost:5000/bundle.js"></script> on http://localhost:5001 (serving the files as before), the browser (Chrome 71) won't load the source map. Is this a bug in the browser or something else?

Answer

Yes it does not work in Chrome. The solution is to include the source map not via the header but via the //# sourceMappingURL=<url>.map.
