Using PounchDB Memory Adapter with Rollup

[eric1234]

I'm trying to use PouchDB's memory adapter with Rollup. Here is an example script that does nothing but setup PouchDB with the memory adapter:

import PouchDB from 'pouchdb-browser'
import MemoryAdapterPlugin from 'pouchdb-adapter-memory'

PouchDB.plugin(MemoryAdapterPlugin)

Here is a Rollup config that will at least make a bundle with that script

import commonjs from '@rollup/plugin-commonjs'
import resolve from '@rollup/plugin-node-resolve'
import polyfillNode from 'rollup-plugin-polyfill-node'

export default {
  input: 'index.js',
  output: {
    format: 'iife',
    name: 'app',
    file: 'bundle.js'
  },
  plugins: [
    commonjs({
      requireReturnsDefault: "auto",
    }),

    polyfillNode(),

    resolve({
      preferBuiltins: true,
      browser: true
    }),
  ]
}

When I attempt to load it in the browser it ends up getting error related to the inherits util method and the readable-streams package. I think this is because some of the dependencies of PouchDB memory adapter explicitly use some Node polyfills (such as those two), but the above polyfill plugin is also providing that perhaps in an incompatible way. If I remove the polyfill plugin it complains about several other node built-in modules that are not available for a browser bundle.

Anybody using the memory adapter in a browser and able to successfully bundle it?

Ended up finding out the answer. Rather than repeat it here I have it posted over on StackOverflow at:
