@nitric/react-animated-term

Animated terminal component for React

Rewrite of react-animated-term in Typescript with added features

Installation

npm install @nitric/react-animated-term

yarn add @nitric/react-animated-term

You can then import react-animated-term and its styles.

import Terminal from '@nitric/react-animated-term';
import '@nitric/react-animated-term/css/styles.css';

Usage

The terminal commands and output lines are specified as an array of objects. The text field specifies the content of the line and cmd is used to specify whether the line is a command or an output. The interval prop specifies how often the terminal should be updated.

import React from 'react';
import Terminal from '@nitric/react-animated-term';

const termLines = [
  {
    text: 'ls',
    color: 'blue', // you can add colors
    cmd: true,
  },
  {
    text: 'index.js    package.json    node_modules',
    cmd: false,
  },
  {
    text: '',
    cmd: true,
  },
];

const MyComponent = () => {
  return <Terminal lines={termLines} interval={80} />;
};

Framed Animation

You can also render output that consists of frames by specifying the individual frames. With a framed output, the text field specifies the final output that should be rendered after all the frames have been rendered. Delays can also be specified for individual frames and commands.

import React from 'react';
import Terminal from '@nitric/react-animated-term';
const spinner = ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏'];
const termLines = [
  {
    text: 'node example.js',
    cmd: true,
    delay: 80,
  },
  {
    text: '✔ Loaded app',
    element: <><span className="text-green">✔</span> Loaded app<>,
    cmd: false,
    repeat: true,
    repeatCount: 5,
    frames: spinner.map(function (spinner) {
      return {
        text: spinner + ' Loading app',
        delay: 40,
      };
    }),
  },
  {
    text: '',
    cmd: true,
  },
];

const MyComponent = () => {
  return <Terminal lines={termLines} interval={80} />;
};

Themes

A white themed terminal is specified using the white prop.

import React from 'react';
import Terminal from '@nitric/react-animated-term';

const MyComponent = () => {
  return <Terminal lines={termLines} interval={80} white />;
};
