Cross-platform Terminal Emulator In Vanilla JavaScript – vanilla-terminal

A lightweight cross-platform terminal emulator written in vanilla JavaScript without any dependencies.

Supports desktop/tablet/mobile and you can define your own shell commands in the JavaScript.

How to use it:

Create a container to place your terminal.

<div id="vanilla-terminal"></div>

Download and place the JavaScript ‘vanilla-terminal.js’ right before the closing body tag.

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

Create a new terminal instance inside the container you created.

const myTerminal = new VanillaTerminal();

Add your own shell commands to the terminal.

const myTerminal = new VanillaTerminal({
      commands: {
        flavour: (myTerminal) => {
          myTerminal.output('...')
          myTerminal.setPrompt('...');
        },
        ping: (myTerminal, parameters) => {
          myTerminal.output('Ping to <u>${parameters[0]}</u>...');
        },
      },
});

      // target container
