Polyfill node os module with vite/rollup.js

Question

I'm working on a Vite project which uses the opensea-js package. This package depends on xhr2-cookies. which imports os, http, https and some other internal node modules.

I'm getting this error when trying to call any of the opensea methods:

Uncaught (in promise) TypeError: os.type is not a function
    XMLHttpRequest2 xml-http-request.ts:102
    prepareRequest httpprovider.js:61
    sendAsync httpprovider.js:116
    node_modules opensea-js.js:24209

Tracing this error it comes from constructing the useragent string.

I tried installing rollup-plugin-polyfill-node and adding it to vite.config.js but still getting the same error:

import path from 'path'
import vue from '@vitejs/plugin-vue'
import nodePolyfills from 'rollup-plugin-polyfill-node'
import { defineConfig } from 'vite'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: {
      '@': path.resolve(__dirname, 'src'),
    },
  },
  server: {
    port: 8080,
  },
  define: {
    'process.env': {},
  },
  build: {
    rollupOptions: {
      plugins: [
        nodePolyfills(),
      ],
    },
  },
})

I've also tried patching the file manually with patch-package, which fixes the os error however then fails when trying to sending the request (which uses http/https modules which also need to be polyfilled).

Answer 1

In my project I solved with a configuration like this. I have described the solution in a short article.

// yarn add --dev @esbuild-plugins/node-globals-polyfill
import { NodeGlobalsPolyfillPlugin } from '@esbuild-plugins/node-globals-polyfill'
// yarn add --dev @esbuild-plugins/node-modules-polyfill
import { NodeModulesPolyfillPlugin } from '@esbuild-plugins/node-modules-polyfill'
// You don't need to add this to deps, it's included by @esbuild-plugins/node-modules-polyfill
import rollupNodePolyFill from 'rollup-plugin-node-polyfills'

export default {
        resolve: {
            alias: {
                // This Rollup aliases are extracted from @esbuild-plugins/node-modules-polyfill, 
                // see https://github.com/remorses/esbuild-plugins/blob/master/node-modules-polyfill/src/polyfills.ts
                // process and buffer are excluded because already managed
