Installation

Run

$ npm install

in the root of the directory to install the necessary files.

Install parcel.

$ yarn global add parcel-bundler

or

$ npm install -g parcel-bundler

Building

$ npm run build

for a single build of the code or

$ npm run start

for a continuous build on filesave.

$ parcel index.html

to build the "application" (currently just an empty page that serves the js output).

Notes

Right now the result type is the opposite order of Belt.Result.t since that's the convention I was used to. I export a result constructor in Utils for convenience which is flipped. It'll get fixed eventually...
