I recently released a tool that will manage all of this stuff (see the accompanying blog post), but I figure it's good to document what I went through for future ocaml cross-compilation spelunkers.

Lots of people have come into the discord channel asking about how to elegantly deal with async things. We've got Promise.then_ and good old callbacks, but having a syntax like async/await can really make things nicer when you have a lot of async going on. So far in the web clients I've made, there hasn't been enough asynchrony to really feel that pain, but I thought it would be an interesting challenge to tackle anyway.

Are you a big fan of React, and want to know more about Reason/OCaml? I made this for you!

This tutorial was updated on Nov 8, 2017 for the new "v3" syntax of Reason.

Reason is a project that adds a JavaScript-style syntax and a bunch of conventions and tooling to OCaml. The goal is to make this awesome language, with its powerful type system and robust multi-platform compiler, accessible to a broader audience. It's backed by the good folks at Facebook who invented and built React, and so naturally having best-in-class React interop has been a high priority.

This tutorial aims to give you a nice introduction to the syntax and type system of Reason, through the ReasonReact library. We'll be building a simple Todo list application.

Someone came into our discord channel a few days ago asking "Is Reason suitable for migrating a large production JavaScript codebase incrementally?" I answered "Yes, but wait 6 months."

What's the current status? At the moment, we're mostly in the realm of "enthusiasts who are OK with being on the bleeding edge, and want to help build out the foundation in their spare time."

So you're all ready to write some Reason but you need to call a JavaScript function? Or maybe you can't figure out how to write something in OCaml-land and wish you could just bail for a minute & write it in JavaScript? Fortunately, both of those are fairly easy to pull off.

A couple of people have asked me how to get up and running recently, so I thought I'd put something together. If you're looking for a "just clone this repo & go", here's a very simple boilerplate I put together for this post, or you can check out the reason-react-example repository.
