Simple local development environment for web apps

/in /by
  1. Open your app working directory
    • There you should have at least index.html
  2. Launch http-server in your terminal
    • If you haven’t installed it yet: npm install http-server -g
  3. Launch chromium-browser --disable-web-security --user-data-dir=/tmp/something in your terminal to allow all origins (temporary ignore  CORS mechanism )
    • Make sure you don’t have other instances open: pkill -f chromium
  4. Type in the address bar one of the address from your http-server info to access to your app

Note: Use Chromium without security just with your own code for testing and development, do not browse with it and beware about using third-party software in your code.

Post JSON data to an URL

/in /by

The easiest way to do a POST in JavaScript: using fetch.

Get JSON data from an URL

/in /by

AJAX request using ES6 Promises with fetch and XMLHttpRequest. Notice that the url needs https because we request from https and the server should allow all origins (Access-Control-Allow-Origin: *)

Fetch is simpler and cleaner, it avoid callback hell and having to remember the complex API of XMLHttpRequest.
