Have you considered building via ebuild or swc?

Hello!

About code transpiling, we have a two targets:

• babel as default transpiler
• swc as experimental transpiler

At this moment, unfortunately you can't use swc transpiler, because of our File-system routing depends on loadable-components babel plugin. There is no official swc plugin - https://github.com/gregberge/loadable-components/issues/529, exists only custom Next.js implementation.

Our future plans, when swc plugin system will be more stable (e.g. https://github.com/swc-project/swc/issues/2175 problem will be solved), to convert our important babel plugin to swc and present this loader officially.

About bundling, we also have a two targets:

• webpack as default bundler
• vite as alternative

But unlike swc case, we have no implementation with vite. For today, we just completed some preparation to made our @tramvai/cli bundler-agnostic.

@SuperOleg39 I like vite, can u provide an example?

[SuperOleg39]

We don't have examples, only ticket in our backlog)

As a preparation, webpack was separated to builder abstraction - https://github.com/Tinkoff/tramvai/tree/main/packages/cli/src/builder/webpack, this is all what we have at this moment.

It's not a custom next.js implementation. Next.js doesn't do anything new to SWC per se, it's just that that plugin is packaged inside a next.js repository, nothing else.

It's even published on npm and available for download and usage.

Oh, I did not look at the dates 😄

Pardon me

[SuperOleg39]

Yes, @swc/plugin-loadable-components is new and shiny)

Anyway, next has their own plugin - https://github.com/vercel/next.js/blob/canary/packages/next-swc/crates/core/src/next_dynamic.rs - port of Babel version, which was fork of loadable Babel plugin))

Soon we will finish our swc integration, and already fork this new @swc/plugin-loadable-components - https://github.com/Tinkoff/tramvai/tree/main/packages/swc/plugins/lazy_component

[SuperOleg39]

Full swc support is finished, and last changes shipped in v2.49.3 version!

After enabling swc loader, cold start for develompent build will be improved significantly.

Warm start and rebuild have a some small improvements, because of webpack@5 file-system caches
