process.env is removed from Vite. Now they use import.meta but it also doesn't work in a Vite config file only. In the Vite config, we have to use the loadENV method.

process is now removed from vite also in vite config we cant access env direct, instead we have to use loadENV from vite, like below:- import { defineConfig, loadEnv } from 'vite'; export default defineConfig(({ mode }) => { const env = loadEnv(mode, '.', 'VITE_'); return { base: env.VITE_BASE_PATH || "/your-repo-name", // Other Vite configurations }; });

Nice Info
