It seems that vite does not do automatic polyfills anymore - vite 4.0.0

How do you guys go about this? I have tried multiple variations of what I could find over the internet and none of them seems to be solid.

Try using the npm package vite-plugin-node-polyfills.

Install the package via npm install --save-dev vite-plugin-node-polyfills, then add the plugin to your vite.config.ts file.

import { defineConfig } from 'vite'
import { nodePolyfills } from 'vite-plugin-node-polyfills'

export default defineConfig({
  plugins: [
    nodePolyfills(),
  ],
});

See the package repo for full customisation options: for example, you can also include only the polyfills that are relevant to your project.

plugins: [
  nodePolyfills({ include: ['fs', 'stream'] }),
],

I tried to use vite-plugin-node-polyfills but trying to make a sample like:

function useReturnStdOut() { 
  const [localArch,setLocalArch] = useState<string | null>(null); 
 
  const getData = async()=>{  
 
    exec.exec("ls", (error, stdout, stderr) => { 
      if (error) { 
        console.error(`exec error: ${error}`); 
        return; 
      } 
      if (stdout) { 
        console.log(`stdout: ${stdout}`); 
        setLocalArch(stdout); 
      } 
      if (stderr) { 
        console.error(`stderr: ${stderr}`);   
      } 
    });  
 
  } 
   
  useEffect(() => { 
    getData(); 
  }, [localArch]); 
 
  return localArch; 
} 

running on host from my mobile phone and debugging it I face always this error : Uncaught (in promise) TypeError: Cannot read properties of null (reading 'exec') even if I check if the arguments , stdout - stderr - error, exists ..... maybe shall I have missed something about this library even if I call it asynchronously?...

thanks in advance!

I encountered the same issue "cannot be marked as external" when working with the bip39 package and getting error because of buffer not defined. I tried many stuffs so not sure how what I solved, but here is my configuration (working with svelteKit):

In vite.config.js:

import { sveltekit } from '@sveltejs/kit/vite';
import type { UserConfig } from 'vite';

const config: UserConfig = {
    plugins: [sveltekit()],

    resolve: {
        alias: {
            // polyfills
            Buffer: 'vite-compatible-readable-buffer',
            stream: 'vite-compatible-readable-stream',
            util: 'rollup-plugin-node-polyfills/polyfills/util',
        }
    }
};
export default config;

In layout.ts:

import { Buffer as BufferPolyfill } from 'buffer'

declare var Buffer: typeof BufferPolyfill; globalThis.Buffer = BufferPolyfill

In app.html:

<script>
    /**
     * this is a hack for error: global is not defined
     */
    var global = global || window
</script>

I hope it helps. I'm new to svelte and I don't 100% know what I'm doing :p
