#12446 1231a2e Thanks @jamesopstad! - Infer upload_source_maps setting in the output Worker config from the build.sourcemap setting in the Vite config.
If build.sourcemap is enabled for a Worker environment, as in the following example, "upload_source_maps": true will now automatically be added to the output wrangler.json file.
This removes the need to additionally specify the upload_source_maps property in the input Worker config.
export default defineConfig({
environments: {
my_worker: {
build: {
sourcemap: true,
},
},
},
plugins: [cloudflare()],
});Note that if upload_source_maps is set in the input Worker config, this value will take precedence.
This makes it possible to generate source maps without uploading them.
#12393 fd8b3e5 Thanks @BlankParticle! - Provide proxy shared secret to Miniflare so that the Worker receives the original Host header
