🚀 A terminal emulator in React

👀Table of contents

🎉Introduction

terminal-intro

Try the demo

React-terminal is a terminal emulator inspired by vue-terminal.

If you are looking for an interactive application that displays information, then React-terminal would be a good choice for you.

Some of cool features of this React component are:

  1. Built-in system commands:ls cd pwd echo etc
  2. You can use tab to automatically complete the command
  3. Command history using arrow up and down
  4. Customizable commands, prompt and label style
  5. Support callbacks(async/non-async) for commands

Some ideas for using React Terminal in your next project:

  • Personal website: Make your personal website or web resume a command-line interface.

  • Demos: Create mock commands in JavaScript for your CLI app, and let users try out commands in their browser with simulated output.

💡Install

npm i react-terminal-app

OR

yarn add react-terminal-app

This package also depends on react so make sure you've already installed it.

✨Usage

import Terminal from 'react-terminal-app'

// refer to: https://github.com/Tomotoes/react-terminal/blob/master/demo/src/commands
import dynamicList from 'command/dynamic'
import staticList from 'command/static'

const cmd = {
  dynamicList,
  staticList
}

const config = {
  prompt: '➜  ~ ',
  version: '1.0.0',
  initialDirectory: 'workspace',
  bootCmd: 'intro'
}

function App() {
   return <Terminal cmd={cmd} config={config} />
}

DataStruct

PropTypes

{
	cmd: PropTypes.shape({
      dynamicList: PropTypes.object,
      staticList: PropTypes.object
    }).isRequired,
 
    config: PropTypes.shape({
      initialDirectory: PropTypes.string,
      prompt: PropTypes.string,
      version: PropTypes.string,
      bootCmd: PropTypes.string
    }),
        
    className: PropTypes.string,
}

Command

Command is an object, used to define message showed in terminal:

interface ICommand {
    time?: string; // time to show time before command body
	type?: string; // label to show a label before command body
	label?: string; // type to set command's type, will set a class to command's label part, there is 7 builtin types: error, success, info, warning, system, black, time
    content?: string; // the main text showed in terminal.
    [propName: string]: any;
}
type command = ICommand | string

Props

className

The class name of the root node, you can customize the style.

Defaults to react-terimnal-app

config

  1. prompt

    The text to show before the prompt.

    Defaults to ➜ ~ .

  2. initialDirectory

    Directory opened by default in the terminal.

    Defaults to src.

  3. version

    The version number of the terminal, you can execute the version command to view.

    Defaults to 1.0.0.

  4. bootCmd

    The name of the command to be executed when the terminal is initialized.

    Defaults to intro.

cmd

  1. dynamicList

    The list of interactive commands.

    {
      commandName: {
      	description: '...',
        run(print, input) {
          // print: a function that allow you to print command to the terminal
          // input: Command parameters currently entered
          // eg: echo HelloWorld, input The value passed in is 'HelloWorld'
          return new Promise((resolve,reject) => {
            // do something
          })
        }
      }
    }

    Example: Define an open command to open the entered URL.

    export default {
      open: {
        description: 'Open a specified url in a new tab.',
        run(print, input) {
          return new Promise((resolve,reject) => {
            if (!input) {
              return reject({ type: 'error', label: 'Error', content: 'a url is required!' })
            }
            if (!input.startsWith('http')) {
              return reject({ type: 'error', label: 'Error', content: 'Please add `http` prefix!' })
            }
            print({ type: 'success', label: 'Success', content: 'Opening' })
            window.open(input, '_blank')
            resolve({ type: 'success', label: 'Done', content: 'Page Opened!' })
          })
        }
      }
    }
  2. staticList

    The list of commands that only show data

    {
      commandName: {
      	description: '...',
        list: [ <command> ]
      }
    }

    Example: Define a skills command to display the skills you master.

      skill: {
        description: 'Return a list of my skills and my rating of them.',
        list: [
          { type: 'success', label: 'A', content: '· JavaScript 99/100' },
          { type: 'success', label: 'A', content: '· Go 90/100' },
          { type: 'success', label: 'A', content: '· Java 80/100' },
          { type: 'success', label: 'A', content: '· Kotlin 80/100' }
       ]}
