React, Uncaught ReferenceError: process is not defined

[0sama]

Describe the bug

After upgrading to v3 from v2.9 process.env got removed in library mode, defining new variables won't fix the issue.

in dev-mode everything works fine, this only occurs on production build.
react18 entry file in node-modules tries to access process.env.NODE_ENV which causes this issue
due to my requirements, I also can't use react as an external package.

this is my config file:

import react from '@vitejs/plugin-react';
import { defineConfig, loadEnv } from 'vite';
import svgrPlugin from 'vite-plugin-svgr';
const { resolve } = require('path');

export default defineConfig(({ mode }) => {
  const env = loadEnv(mode, process.cwd(), '')

  return {

    // define: { // none of the below works!
    //   'process.env': {}
    //   'process.env': JSON.stringify(env),
    //   'process.env.NODE_ENV': 'production',
    // },
    plugins: [
      react(),
      svgrPlugin({
        svgrOptions: { // ...svgr options (https://react-svgr.com/docs/options/)
          icon: true,
        },
      }),
    ],
    build: {
      sourcemap:true,
      // build as a library
      lib: {
        entry: resolve(__dirname, env.ENTRY === 'desktop' ? 'src/desktop/DesktopEntry.jsx' : 'src/mobile/MobileEntry.jsx'),
        name: 'fitting-station',
        fileName: (format) => `fs-${format}.js`,
      },
    },
    resolve: {
      alias: {
        '@helpers': resolve(__dirname, 'src/common/utils/helpers.js'),
        '@style': resolve(__dirname, 'src/common/components/Style.jsx'),
        '@globalActions': resolve(__dirname, 'src/common/redux/store/actions/globalActions.js'),
        '@icons': resolve(__dirname, 'src/common/assets/icons/index.js'),
      },
    },
    server: {
      port: 3000,
      hmr: { clientPort: 3000 },
      strictPort: true, 
    }
  };
});

Reproduction

yarn build and then

cd external-project
yarn install
yarn start

the vite web-component is not loaded and will give the error in the console.

I'm having this same issue
Using Vite with cypress, I'm parsing the files in lib mode, and the same error comes up

      on('file:preprocessor', async (file) => {
        const { filePath, outputPath } = file;
        const filename = path.basename(outputPath);
        const filenameWithoutExtension = path.basename(outputPath, path.extname(outputPath));

        const viteConfig = {
          jsx: 'react',
          plugins: [flowPlugin(), react()],
          build: {
            emptyOutDir: false,
            minify: false,
            outDir: path.dirname(outputPath),
            sourcemap: true,
            write: true,
          },
        };

        if (filename.endsWith('.html')) {
          viteConfig.build.rollupOptions = {
            input: {
              [filenameWithoutExtension]: filePath,
            },
          };
        } else {
          viteConfig.build.lib = {
            entry: filePath,
            fileName: () => filename,
            formats: ['es'],
            name: filenameWithoutExtension,
          };
        }

        await vite.build(viteConfig);
        return outputPath;
      });

production needs to be wrapped with double-quotes. See docs.

    define: {
      'process.env.NODE_ENV': '"production"'
    },
