@moonbitlang
is a very young language but it's the computing platform built for the next 30 years. We are very bullish on its potentials especially in the area of codesign with AI.

The forthcoming BuckleScript version 8 will be the largest release since the initial open source! The initial goal that make the fastest JS target compiler generate the fastest JS code — an ambitious goal & bold claim will become true.

BuckleScript 7.0.0-dev.1 released for testing, see the

Final answer to the scalability of BuckleScript: a monorepo with 4096 modules, changing the root node which has 3641 dependencies, it took less than 1 sec to finish building, stay tuned for the next version!

Today is my last day. I am grateful to Meta for the unique opportunity to work on

BuckleScript 8 is out. It has lots of great stuff, great stack trace, lazy evaluation and better performance. We also publish a new post -- "Make generated JavaScript Inline Caching friendly using types in BuckleScript version 8"

In next release of bs-platform, to toy around

Excited to introduce
@moonbitlang
for Cloud and Edge computing! ✨ Build as fast as
@golang
. ✨ Run as fast as
@rustlang
. ✨ Tiny size of Wasm output.
Plus, start with a great cloud IDE right out of the box!

The

The next release of
#bucklescript
will be big, it will compile ocaml records into idiomatic js objects(joint effort with
@ccrisccris
), it opens door for lots of use cases, will publish a post about it!

BuckleScript 7 is enabled by default for

bs-platform 4.0.17 released. It delivers incredible incremental build perf.
For a large repo which contains 4096 modules, changing the node which has more than 3000 dependents, finished within 400ms.

BuckleScript already set a high bar about the quality of generated code, it keeps getting better each release, see how the generated code evolves in the pic(top -> bottom), more advanced type based optimization coming soon!

132
There's a mis-understanding that BuckleScript is *just* an OCaml to JS compiler. No! There're lots of innovations inside the compiler, we plan to polish those ideas from the academia and make it more practical in industry settings, the next version will bring some cool stuff!

2018 resolution: if you want performance in JS platform, BuckleScript is the go-to language, the key selling point of BS will be its performance

Small things add up(left -> right in the pic): spent a weekend improving the quality of generated code from BuckleScript compiler, try best to prevent regression while keep improving!

125
One big difference between ReasonML and other typed Alt-JS language is that we value performance as important as soundness, soundness is nice to have but the real goal is to get the optimal code for industrial deployment. We will deliver most of our goals this year
4

125
Thanks to amazing work by
@ccrisccris
, we are going to compile local modules into idiomatic js objects. This would make OCaml's advanced module system(including functor) much more usable to
#bucklescript
@reasonml
users, lots of great stuff coming in next release.

Did you have trouble debugging complex pattern matching in
@reasonml
using
#bucklescript
? Another major contribution by
@ccrisccris
, generated pattern match code will be annotated with constructor names in next release

Working on the last release of BuckleScript in 2019, as a gift for New Year, we will ship zero cost abstraction for high rank polymorphism and existential type encoding(great for JS interop) The compiler improved a lot this year, try
@reasonml
in 2020!

I will be more focused on BuckleScript and

Being so excited that we are very close to provide an end-to-end solid tools for web-dev workflow, zero deps, just bs-platform, no extra bundler any more, instant feedback loop!!

A small gif shows how awesome R & B (

In master, we added support for record label renaming to map records to Js objects precisely, which opens a door to bindings in more native fashion. You can also use our optimized pattern match compiler to process js object (see the pic for excitement)

ICYMI, we made a new release

If you have a super large mono repo which has more than 5k source files, do you still expect instant feed back loop, (Edit - Rebuild - Test within one sec)? That's the best gift that BuckleScript will provide for the New Year!!

Thanks to recent features landed in ninja build, we will shave another 10ms in incremental build feedback loop for
#bucklescript
and
@reasonml
projects. 10ms is important, that’s how we try to approach 100ms feedback loop!

Being maintained by a small team doesn’t mean less contributions, for the BuckleScript compiler, we passed more than 10,000 commits over 5 years, not an easy achievement. Focus and dedication plays a more important role.

Didn't tweet that much in the last year, since I have been busy working on something truly amazing on top of

@rescriptlang
, it has a much larger scope, so exicted!!

Thanks to
@rescriptlang
focusing on the JS backend, we are going to add more and more type based optimizations which are impossible in typescript. The performance of rescript's compiler will be even faster, 10x faster than tsc is the baseline.

A post about what's coming in next release of BuckleScript: loading stdlib from memory, installation time is 10 times faster and postinstall free on Tier one supported arch(Linux/Mac/Windows), compilation time should also be faster, feedback is welcome!

We are working on in memory loading cm* files for

It is the love of JS and OCaml which drives me to make BuckleScript, unclear why people hate JS so much for no good reasons, the faults of JS lies in almost all dynamic languages

We have built the alt-js compiler of the highest quality in the last few years, it’s called
@rescriptlang
or you may use it in
@reasonml
but we were seriously lagging behind in the community building and tooling. It’s more challenging than tech but we’ll try my best to fix it.

In next release, we will reuse part of the

BuckleScript 1.5 even better FFI and native support for

Three live pics to show how we improve performance of the build(test on project of 4804 large files): first apply a better algorithm: 363ms -> 289ms, later optimize a hot path (from 72.7us to ), 289s -> 260ms.

Agree with most pain points about OCaml. That’s why we build rescript: reuse the best part of ocaml—type system & build a community just doing one thing well with a coherent vision

Introduce a tool bstracing which visualize your build profile in next release. Below is a comparison of building the same project against current version. Yes! Perf is even better in next release, clean building a project of 1250 files: 4790ms -> 4223ms!
