Issues with Parcel bundler

[palfrey]

Describe the problem

Trying to build an app with auth0-react and Parcel got me the following warning:
Could not load existing sourcemap of "../node_modules/@auth0/auth0-react/dist/auth0-react.esm.js". Not sure if there's something that needs changing in Parcel config, or if there's a packaging issue from the auth0-react end?

What was the expected behavior?

No warnings!

Reproduction

I've got a Typescript project and the root file I'm telling Parcel to build from has the line import { Auth0Provider, AppState } from '@auth0/auth0-react'

Environment

• auth0-react: 1.2.0

Hi @palfrey

This is a known issue with using spa-js and Parcel 1.x, caused by parcel-bundler/parcel#2408

There's a couple of workarounds on auth0/auth0-spa-js#427 namely using parcel with --no-source-maps as described in parcel-bundler/parcel#2408 or using parcel@2

We had that issue with Vite, the solution was to avoid using globals: {} in vite.config.ts
