vanilla-terminal

🍦A simple and lightweight Javascript web browser terminal

Web apps are great. But sometimes instead of all the double-clicks, mouse pointers, taps and swipes across the screen - you just want good old keyboard input. This terminal runs in a browser, desktop or mobile. It provides a simple and easy way to extend the terminal with your own commands.

How to use

Include vanilla-terminal.js in your HTML:

<script src="vanilla-terminal.min.js"></script>

Define an HTML div tag where the terminal will be contained:

<div id="vanilla-terminal"></div>

Create a new terminal instance and convert the DOM element into a live terminal.

const terminal = new VanillaTerminal();

If you want use another DOM element as container just set the property container:

const terminal = new VanillaTerminal({ container: 'my-vanilla-container' });

Add your own commands

If you want add your own commands to the terminal just pass a object using the property as your command and the value as the callback.

const commands = {
  flavour: (instance) => {
    instance.output('There is only one flavour for your favorite🍦and it is <b>vanilla<b>.')
    instance.setPrompt('@soyjavi <small>❤️</small> <u>vanilla</u> ');
  },
 
  ping: (instance, parameters) => {
    instance.output('Ping to <u>${parameters[0]}</u>...');
  },
};
 
const terminal = new VanillaTerminal({ commands });

Now in your terminal could type your new commands:

> help
These shell commands are defined internally:
flavour, ping, clear, help, version, wipe
 
> flavour
There is only one flavour for your favorite🍦and it is vanilla.
