getting Pouchdb working under Vite?

[baradhili]

Hi All,
getting pouchdb to run seems to be tough under Vu3/Vite

So far:..
shimmed global in index.html - <script>window.global = window</script>
running into
Uncaught Error: Module "events" has been externalized for browser compatibility and cannot be accessed in client code.

Tried pulling events in via rollup-plugin-node-polyfills in vite.config.js but had no effect (I might have done it wrong though)

Anyone managed to get this working?

Thanks

ok obscure...

fix was as per the end comment in pouchdb/pouchdb#8130

It was solved by setting

{
    optimizeDeps: {
        allowNodeBuiltins: ['pouchdb-browser', 'pouchdb-utils']
    }
}

in the rollup config along with
yarn add events.

I am working with svelteKit and it has been impossible to make pouchdb work with it.

I get the following errors:
