melange-opam-template

A simple project template using Melange with opam.

If you are looking for a template with esy, check melange-esy-template.

Quick Start

make init

# In separate terminals:
make watch
make serve

React

React support is provided by @rescript/react. The entry point of the sample React app is src/ReactApp.re.

Commands

You can see all available commands by running make help or just make. Here are a few of the most useful ones:

  • make init: set up opam local switch and download OCaml, Melange and JavaScript dependencies
  • make install: install OCaml, Melange and JavaScript dependencies
  • make watch: watch for the filesystem and have Melange rebuild on every change
  • make serve: serve the application with a local HTTP server

JavaScript output

Since Melange just compiles source files into JavaScript files, it can be used for projects on any JavaScript platform - not just the browser.

All ReasonML/OCaml/ReScript source files under src/ will be compiled to JavaScript and written to _build/default/src/* (along with some other build artifacts).

For example, src/Hello.ml (using OCaml syntax) and src/Main.re (using ReasonML syntax) can each be run with node:

node _build/default/src/Hello.bs.js
node _build/default/src/Main.bs.js
