🎉 Getting Started

This document aims to be a gentle introduction to the framework and its features. It is an elementary preface with examples and links to other parts of the documentation. Let's get start!

Installation

Let's say that you've already has Node.js installed and already setup a ReasonML project.

$ npm install --save resver-rex

then add it to bsconfig.json

{

...

"bs-dependencies": ["resver-rex"]

...

}

Launch Server 🚀

/* file: Server.re */

open Rex;

let handler = HttpHandler.({verb, path, res}) => {

switch (verb, path) {

| (Verb.Get, []) => res |> Response.send("Hello world!")

| _ => res |> Response.send("Not found")

};

};

App.make(~port=3000, ~handler, ());

Your code should be compiled to Server.bs.js, then run

$ node ./Server.bs.js

then the app should live at http://localhost:3000

Handler

there is only one function that run them all. ~handler.

Params:

req: Request.t, // request object

res: Response.t, // response object

verb: Verb.t, // HTTP Methods for example GET, POST, etc.

path: Path.t // list of string that separated by "/"

query: Js.Json.t, // query string

body: Body.t, // parsed body

pubsub: PubSub.t('a) // publish/subscribe (used in websocket)
