Been building a @rescript-lang.org MCP server lately, letting an LLM truly see a codebase. If you haven’t met ReScript before, this one’s still worth watching . It has a clear case of how localized MCP servers can lift developer tooling. youtube.com/watch?v=stIX... #rescript #mcp

We just landed a new (experimental) feature for v12 - nested record definitions! Records is a corner stone in ReScript. However, they can't be nested without explicit definitions. Until now! Will be especially useful for deeply nested records (like options objects) not intended to be reused.

Records are powerful, but you need explicit definitions for them. We're experimenting with allowing inline record definitions nested inside a record type definition. This will make some of the common use cases for records more ergonomic.

1152

ReScript @rescript-lang.org · 04/01/2025

The new dot completion also works for objects. Objects are structurally typed, doesn't need a type definition, and are quite useful in some scenarios. Completion for object fields will be more ergonomic and get better discoverability with this addition.

0102

ReScript @rescript-lang.org · 03/01/2025

With the new dot completion enhancements in our editor tooling you'll now get completions from the Option module when autocompleting on a record field that's an optional value, instead of just no completions like before.

1163

ReScript @rescript-lang.org · 02/01/2025

Happy new year! We're almost ready to release an exciting editor feature - dot completion everywhere! "." will now trigger completions for more than just record fields. Example: you'll get completions for pipeable functions from the module of that type. Examples and videos ⬇️

I've been playing around with @rescript-lang.org for a React project I'm working on and I'm super impressed with how far it's come since I last checked it out! Also between ReScript and @gleam.run I'm absolutely spoiled when it comes to error messages

An error in a ReScript program that clearly points out the issue and offers a potential solution.

Type inference is simple but powerful. The compiler will infer each type that's unknown by usage. A consequence of this is that prop drilling is really simple, because you rarely have to annotate props. Just using the prop in the component defining it is usually enough.

ReScript @rescript-lang.org · 29/11/2024

In ReScript, pipes are normally used for chaining fn calls instead of method chaining with dots like in JS. This is a common gotcha for JS/TS devs who come to ReScript. To ease the transition we're experimenting with letting the editor tooling complete pipes also via dots.

1216

ReScript @rescript-lang.org · 28/11/2024

In ReScript you can put expressions almost anywhere. Assign expressions to variables, put them anywhere in JSX, put them directly into function arguments, etc. Massive readability and productivity boosters, and you'll love it if you haven't written in a language with it before.

Since v11, ReScript has support for explicit partial application of functions using the "..." syntax at the end of the function call. Partial application of functions is useful in many scenarios, and this explicit syntax makes code easier to read and reason about.

0226

ReScript @rescript-lang.org · 26/11/2024

Pipes are one of the most powerful concepts in ReScript. Pipes let you build function chains easily, with great support for type inference, and great editor support like autocomplete. It's just a syntax transform, so it compiles to regular, efficient JS function calls.

1188

ReScript @rescript-lang.org · 22/11/2024

ReScript has first class support for tagged template literals since v11.1. A useful JS technique that's important for interop, and lends itself well to some pretty interesting use cases!

0124

ReScript @rescript-lang.org · 21/11/2024

Dynamic imports shipped in ReScript v11. You can easily import both entire file modules, as well as single functions. For file modules, you simply await the module itself. For single functions, you use the `import` function. Makes things like React.lazy easy to use.

JSX is a 1st class language feature in ReScript. Since v11.1 you've been able to use any createElement-style JSX transform you'd like with ReScript. Image shows Preact, but there are examples in the community even for non-client side fws, like emitting plain HTML server side.

2203

ReScript @rescript-lang.org · 19/11/2024

ReScript ships with native async/await support that also compiles to async/await in JavaScript. You can pattern match directly on the await, and handle errors in the pattern match as well. No need to wrap things manually in try/catch, the compiler still emits the right thing.

2266

ReScript @rescript-lang.org · 18/11/2024

We shipped a %todo extension point in v11.1. It makes it easy to postpone implementing something but not have the compiler block you continuing working. It'll produce a warning by default, and it's easy to configure the compiler so that it emits a hard error in for example CI.

1154

ReScript @rescript-lang.org · 15/11/2024

In v12 we're hoping to ship Rewatch, ReScript's new build system, made by Jaap and Roland. Below is compiling a 375k LoC repo using the current build system vs Rewatch. 1. Current build system: 33.8s 2. Rewatch: 12.27s Speedup by a factor of 2.75 (!) in this example.

1186

ReScript @rescript-lang.org · 14/11/2024

We'll ship our new standard library Core by default in v12. Core replaces the current standard lib and most of Belt, with one unified experienced that's built to look and feel more like the JavaScript APIs you're used to, while not sacrificing ergonomics.
