the removal of console and debugger statements by esbuild even when not
building for production seems to be a regression, as these were
definitely working in the past.
this change uses the command parameter to configure esbuild to either
keep or indeed remove the respective statements. they are only kept if
command is not "serve".
to avoid having to indent everything in defineConfig() by one block, the
return statement and closing curly brace were added "inline".
the current proxy target IP address is probably only working for a
single developer at a time. this change introduces a vite.user.ts, which
is ingored by GIT, and which can define a proxy_target that works for
the respective developer.
this does not change the default behavior, as the fallback value is
still the old IP address. if the new vite.user.ts file does not exist,
or if it does not export proxy_target, the fallback value is used.
file vite.config.ts adds an example in a comment of how to bootstrap a
vite.user.ts.
