@fkn/vite-plugin

Node-in-the-browser for FKN apps. One plugin aliases the Node builtins to the FKN polyfills, so you write fs / net / dgram exactly as you would in Node and it works in the browser, backed by the FKN platform (networked storage over OPFS + cloud, real TCP/UDP sockets through WebVPN).

// vite.config.ts
import { defineConfig } from 'vite'
import { fkn } from '@fkn/vite-plugin'

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

// anywhere in your app
import fs from 'fs'
import net from 'net'

fs.writeFileSync('/save/state.json', JSON.stringify(state))
const socket = net.connect(443, 'example.com')

It:

• aliases fs + fs/promises to @fkn/fs-polyfill, net to @webvpn/net, dgram to @webvpn/dgram (and their node: forms), with exact-match resolution so a package like fs-extra is left alone;
• falls back to node-stdlib-browser for every other Node builtin (stream, events, buffer, …);
• provides the Buffer / process / global shims the polyfills rely on.

Disable any backend you don't want aliased:

fkn({ net: false, dgram: false }) // fs only
