How to add CORS

[eric-hc]

Does anybody know how to add CORS to a route? I tried adding Express CORS using @UseMiddleware, but no luck

Hi @eric-hc, if you can post your code and the error you get (if you do), I may be able to help.

P.S: I totally missed this post as there are no badges for the Discussions tab 🙂

Appreciate that @mitchelvanbever. Best I can tell, it fails on prefetch requests since there is no logic to handle OPTIONS. I tried adding middleware functions that run before the main class body, but that didn't seem to solve it.

Thanks for the extra info @dimitriborgers3mint. I believe @ggurkal has found the issue. We'll let you know when the fix is released!

@dimitriborgers3mint you are right about that there's no logic to handle the OPTIONS request. now i'm adding an extra parameter to http decorators for configuration, like @Post({ extras: ['OPTIONS'] }) so that we know that handler also handles OPTIONS next to POST request (even though in your case, OPTIONS is handled by the middleware, not by the actual handler).

Awesome! Thank you @ggurkal @mitchelvanbever for all the help!

Hi @dimitriborgers3mint

v2 just got released and it includes the needed functionality for CORS to work.
