If you're trying to use GUN with vite build tool, you can bump into a couple of issues.

First is the fact that vite pre-bundles the dependencies, so you can't import something from inside of them. That's exactly what we do when we import SEA from 'gun/sea' and all the gun/libs too. So you need to add a list of included optimized dependencies to vite.config.js for vite to know that you'll need their insides.

Second - there's the problem with vite including the 'text-encoding' node polyfill that is required by SEA.js in node environment and is not needed in modern browsers. It unnecessary blows up the file size of your js bundle by +700kB. We don't want that. So first step is to exclude the package from the build. This works, but you'll encounter an error of a wrong import. So here comes the solution noted by Evan You himself. We just create a custom plugin, that properly removes the unnecessary extension.

With the help of @jojobyte in Gun discord channel we figured out a rather universal function to do the job. So here's the final vite.config.js that makes Gun play nice with vite:

const moduleExclude = match => {
  const m = id => id.indexOf(match) > -1
  return {
    name: `exclude-${match}`,
    resolveId(id) {
      if (m(id)) return id
    },
    load(id) {
      if (m(id)) return `export default {}`
    },
  }
}

export default {
  optimizeDeps: {
    include: [
      'gun',
      'gun/gun',
      'gun/sea',
      'gun/sea.js',
      'gun/lib/then',
      'gun/lib/webrtc',
      'gun/lib/radix',
      'gun/lib/radisk',
      'gun/lib/store',
      'gun/lib/rindexed',
    ],
  },
  plugins: [
    moduleExclude('text-encoding'),
  ],
}

Then you'll need to import gun and all the libs in your app.

import Gun from 'gun/gun'
import SEA from 'gun/sea.js'
import 'gun/lib/radix'
import 'gun/lib/radisk'
import 'gun/lib/store'
import 'gun/lib/rindexed'
import 'gun/lib/webrtc'
import 'gun/nts'

export const gun = Gun({peers: ['https://your.gun.peer'], localStorage:false})

And you're good to go! You can clone a @gun-vue/demo template to have an easy start. It also includes some very useful vite plugins pre-configured. If you manage to improve the setup - please send a PR to the repo.

@gun-vue – is where the peer-to-peer database of Gun meets the reactivity system of Vue 3. Easy to import composables for devs. Pluggable components for UX designers. Relay peer for enthusiasts. Demos and docs for starters. Open source for everyone!
