Nuxt source map setup quite confusing

[GitRowin]

My goal was to setup client and server source maps for Sentry but have them not appear in the final build.

If I understand sourceMaps.ts correctly, the original idea was that if I don't configure Nuxt's sourcemap setting, Sentry should generate hidden source maps for both the client and the server, and delete them after uploading them. Except this doesn't quite work because Nuxt defaults sourcemap.client to false, so the Sentry for Nuxt docs tell you to set sourcemap.client to hidden. This works, but then the source maps are not deleted by Sentry.

According to the Sentry for Vue docs, you can set the sourcemaps.filesToDeleteAfterUpload option to make Sentry delete them. I tried setting it to ["**/*.map"] which did not work. It took me quite some time to figure out that the pattern should start with a . because Nuxt's output folder .output starts with a dot (see "Dots" under Glob Primer). I now use [".output/**/*.map"] with success.

Another option I discovered is simply setting both client and server to undefined. This makes the "built-in" source map generation and deletion logic I described in the beginning work.

I figured I would leave this here, maybe it helps someone else or maybe it can be used to improve the documentation.
