How do I get env variable (set from cli) in vite.config?

[Jax-p]

According to this thread I've tried everything but I still can't get my env variables.

I've command:

SOMETHING=whatever tsc && vite build

It works if I try to dump process?.env?.SOMETHING anywhere else (ex. tailwind config) it shows whatever but I can't get it working in vite.config. This situation is exactly described in this comment but it doesn't work for me. I've also tried loadEnv() but it looks like it is only dot.env loader. Another comment says It is out of date because of conditional config but all it knows it is in "build" command and "production" mode which is useless for this.

How do you get ENV variable in Vite config?

I'm using Vite 2.7.X

Hey, have you tried this in vite.config.ts:

define: {
  'process.env': process.env
}

For dev mode this works for me for getting the git version:

"dev": "VITE_GIT_VERSION=$(git log -1 --pretty=format:%h -- .) vite"

This works, and is accessible in your frontend / client-side scripts via the code snippet import.meta.env.VITE_GIT_VERSION when setting a prefixed VITE_ environment variable within your package.json scripts 🎉

I can't verify whether the above solution could also be used inside of vite.config.ts though.

For anyone facing this exact situation:

Instead of:
SOMETHING=whatever tsc && vite build

Try this:
tsc && SOMETHING=whatever vite build
