@clysema/http

Serves or HTTP static content and/or a REST GET/POST endpoints. Can be used to create a local user interface. Basic Auth.

Install

$ npm install @clysema/http

Usage

config/http.json

{
  "root": "/home/pi/www",
  "host": "localhost",
  "port": 4000,
  "rest": true,
  "get": ["vars"],
  "post": ["controls"]
}

If root property exis, will serve static content placed in /home/pi/www on http://localhost:4000.

If rest is true and get list is defined, a GET in http://localhost:4000/vars endpoint will return app.vars in this example.

If rest is true and post list is defined, a POST in http://localhost:4000/controls will write app.controls (in this example) with the data supplied.

Anywhere in the app code:

// (simply setup app.vars  object) for the get endpoint
app.vars = { date: new Date() };
// log the controls
console.log(app.controls);
