We should investigate if this can help us improve our build times for the webapp.

Heads up @AlicjaSuska @felixfbecker @umpox @valerybugakov @5h1rU @pdubroy - the "team/frontend-platform" label was applied to this issue.

Note: As we're likely not going to work on this in the immediate future, I'm just attaching a branch where I did a quick investigation into using esbuild-loader.

Branch is here: main...esbuild-loader

With webpack/terser/babel the build takes around 2 minutes. Using esbuild-loader we cut this down to around 30 seconds.

We would be able to get even better performance entirely by fully moving to esbuild but this could be a good step if we rely on certain Webpack plugins.

fantastic!
We can run some experiments with Vite as well. #hackaton
