We release fred a while back, our functional reactive editor:

The spirit of innovation we brought earlier on lives again, this time with a modular design and efficiency from Day 1.

Functional Reactive programs are probably the best way for web programming, due to its async nature:

Almost 15 years ago, we brought new ideas to web programming:

- strong static typing
- the JSX syntax 😂
- automatic code split between client and server
- database automation

However, we missed a few things, namely lack of modularity and an inefficient implementation ... 1/2

@amasad @paulg Oh yes! For @opalang we wasted a lot of time implementing a clever HM(X) constraint-based type system. Error messages were horrible, among many other problems. We ended up rewriting the typechecker as a monolithic W algorithm.

@pcarrier @jolon And that’s the typical modern single-page app which is taking over the classical server-side rendering. You will need a server for many things (database, ...) and the first tweet was to discuss about coming back to simpler server-side HTML.

[Opa @opalang]

Do you think server-side rendering will make a comeback?

[Opa @opalang]

@pcarrier @jolon It’s indeed more complex to maintain client runtime in the server. The original Opa approach is to « slice » code between client and server automatically. Many parts become HTML generated server-side.

@reasonml @svensauleau @quentin_smr @jordwalke @andpoul Thanks guys! We love what you do too and hope to find some time again to resume Opa.

@svensauleau @quentin_smr @jordwalke @andpoul Here! https://t.co/kShBGWWM7X
Opa is a cousin language of ours. It pioneers many ideas that could hit mainstream js one day. Check it out!

@BlueShiftBlog @cloud_opinion And now we have primaries in France (1st time for both main parties)... Looks like we're also pick wrong ones.

Opalang vs Typescript which one is better? by Henri Binsztok https://t.co/p6wIch2QhJ

[Opa @opalang]

@inspiredangles Yes. Opa is used in production by multiple companies, including @wallixcom @Placeloop
