Wow that's much more than what I expected. I hope it will help some other people if needed :)

Many thanks to you !!

This is because the tsconfig that the template comes with has a noEmit flag. Remix takes care of building everything in remix build -- everything excepts what's happening in your express server file. Adding the middleware to tsconfig won't do anything because of noEmit.

That part is a bit confusing, but this is why there's a seperate script in package.json specifically for server.ts in the build step "build:server": "esbuild --platform=node --format=cjs ./server.ts --outdir=./",

There are a couple ways to fix this:

1. Keep using esbuild & update the script: build:server": "esbuild --platform=node --format=cjs ./server.ts ./server/middlewares/test.ts --outdir=./",
2. Don't use esbuild and create a new tsconfig profile for the server.

Option 2 is what we use on mana.wiki as well, since the express server itself is light enough that esbuild performance doesn't make a huge difference https://github.com/manawiki/core/blob/main/package.json#L8

I posted a PR to show how it works: fchevallieratecna/remix-v2-server#1

Note that when deploying, you have to make sure the built files are actually shipped. You may want to change the outDir to somewhere else to simplify the process.
