Introduction to Reason Compilation

7 - Compile to JavaScript

Would you like some sweet, sweet interop with the JS ecosystem?

We're gonna use BuckleScript, an OCaml-to-JS compiler that emits really, really clean output.

The other option is js_of_ocaml, a mature and battle-tested compiler.

We're gonna use real third-party dependencies this time around. Check the new package.json's dependencies field (a reason binding to JS functions) and devDependencies field (BuckleScript compiler). npm install in the current directory to get them.

Making this work is surprisingly simple. See the updated run.sh. We've also made modifications to .gitignore and .merlin.

Make sure you read the compiled output. Yes, read it. Trust us on this one!
