When using --servedir, does not bundle

[phlegmaticprogrammer]

I am using esbuild for the first time, so I am not sure if this is a bug.

I am using esbuild version 0.18.15 with node v16.15.1 on macos 12.6.1. The command

./node_modules/.bin/esbuild src/index.ts --outdir=web --bundle --servedir=web --watch

starts a server, and leads to this output when changing src/index.ts repeatedly:

 > Local:   http://127.0.0.1:8000/
 > Local:   http://127.51.68.120:8000/
 > Network: http://192.168.1.90:8000/

[watch] build finished, watching for changes...
[watch] build started (change: "src/index.ts")
[watch] build finished
[watch] build started (change: "src/index.ts")
[watch] build finished
[watch] build started (change: "src/index.ts")
[watch] build finished

But the file web/index.js is not generated!

On the other hand, when I leave out --serverdir=web, then everything works as expected, and web/index.js gets generated.

I found the answer here: #796

Apparently the index.js is not written when using --servedir, but is overlayed in memory over the directory. Cool! Would probably be good to add that to the documentation of "Serve".
