Please set the correct MIME type for .wasm files

[dandv]

I’m trying to run a WebAssembly sample from MDN. It loads a raw .wasm file but runs into this error:

Failed to execute ‘compile’ on ‘WebAssembly’: Incorrect response MIME type. Expected ‘application/wasm’.

Here’s the fiddle: http://jsfiddle.net/dandv/oxt1476q/1/

Any chance for GitHub to set the MIME type correctly for .wasm files?

Thanks!

Thanks for reaching out about this! In short, it’s not possible to manually assign a content-type for files on GitHub Pages.

GitHub Pages supports more than 750 MIME types across 1,000s of file extensions. The list of supported MIME types is generated from the mime-db project, which aggregates MIME types from the Apache and Nginx projects as well as the official IANA list of internet content types.

If you wish to contribute a new mime type to mime-db please see the contributing instructions here.

I hope this helps!
