Webpack memory usage at build time is quite off the charts and does create some OOM errors when developping.

Replacing Webpack by vite will make build times faster and avoid crashes, further improving dev experience on the project.

Things to do:

• replace webpack config by vite config with 100% feature parity
• replace command implementations in package.json for building and serving
• uninstall webpack from the project
• update the github actions if they mention Webpack or directly rely on it
• make sure tauri build still works
