Pitch: what problem are you trying to solve?

We currently use a very old version of webpack. We should either upgrade it + the other dependencies or move to a better build system.

Some alternatives to consider:

• esbuild
• vite
• back to create-react-app managed version
• swc
• ?

• Minimal typescript migration #84

desktop-client has been moved back to CRA.

We still need to figure out a solution for loot-core. Maybe we should consider rollup for it? Or another bundler that's good for building small libraries? TBD

Current status: we’re using the latest version of Webpack at the moment for all packages. I think we’re in a much better place than we were before, but it would be nice to switch to something that builds a bit faster so development can be easier.

My vote is for Vite because of its build speed, community, and easy config.

I've never used SWC - it looks interesting...

We're now using vite which is a significant improvement.
