How to set custom Content-Type for workers static assets?

Looks like I can’t edit the post… My current solution is using a worker with "run_worker_first": true but thats not ideal:

export default {
  async fetch(request, env, ctx) {
    const url = new URL(request.url);

    if (url.pathname.startsWith('/.well-known/matrix')) {
      let response = await env.ASSETS.fetch(request);
      response = new Response(response.body, response);
      response.headers.set('Content-Type', 'application/json');
      return response;
    }

    url.hostname = `www.${url.hostname}`;
    return Response.redirect(url.toString(), 301);
  },
};

I don’t see it in the documentation yet, but support for _headers files as supported in Pages recently landed in Workers Assets (this PR from 3 weeks ago).

I haven’t tried it myself but you should be able to add headers for static assets this way now, avoiding the Worker invocation.
