Web Development with ReasonML

Setting Up the Server

We now have all the parts we need for our project. Let’s set up the server. But first, a disclaimer: this section isn’t intended as a complete guide to using Express. It provides just enough explanation to get our project working.

cd server
npm install --save express # the server
npm install --save bs-express # ReasonML bindings
npm install --save @glennsl/bs-json
npm install --save papaparse # to parse the CSV file
