Termpage 💻


Termpage allows you to create neat functional webpages that behave like a terminal

Why Termpage?

I wanted to build an effective web interface for my raspberry pi home server without thinking too much about design or ux.

Example usage

You can include termpage lib from CDN or install it from npm.

<script src="" type="text/javascript">

npm install --save termpage

The easiest way to get started is to drop this code in your index.html and implement your own terminal logic inside command processing function

<!doctype html>
    <script src="" type="text/javascript"></script>
    <div class="termpage-window" style="position:absolute;top:0;bottom:0;left:0;right:0" id="window"></div>
      Termpage.init(document.getElementById('window'), (command) => {
        command = command.toLowerCase().trim();
        if (command === 'home') {
          return "Welcome to termpage";
        } else {
          return 'Command not found';
      }, {
        initialCommand: 'home'

You can check more complicated usage demo in the examples folder

API documentation


Termpage.init(domElement, commandParser, options)

commandParser = (input) => {
  return response;

input is user input command string

response can be either string or object {text: responseText, commands: ['menuCommand1', 'menuCommand']}

Commands array is used to display command suggestion interface bellow command input. This interface can make life easier for people with mobile devices because they can tap on commands instead of typing them.

List of available options:

    prompt: '$',
    initialCommand: 'home',
    autoFocus: true

Responses can be returned as promises for async commands.

Termpage.replace, and Termpage.color

Termpage.replace together with and Termpage.color helpers can be used to format terminal output without losing monospace alignment between lines.

This code would format Cell1 as a html link and Cell2 as span with color

| Cell1 | Cell2 |
`, {Cell1:''), Cell2: termpage.color('red')})


These default Termpage styles can be freely customized by overriding them with your own css file

.termpage-window {
  background-color: black;
  border: 2px solid #888;
  padding-top: 5px;

.termpage-window * {
  font-family: "Courier New", Courier, monospace;
  font-size: 16px;
  color: #ddd;

.termpage-input {
  background-color: #222;
  color: #ddd;
  caret-color: white;

.termpage-block, .termpage-input {
  line-height: 20px;

.termpage-block {
  padding-left: 5px;
  padding-right: 5px;

.termpage-window a {
  background-color: #888;
  text-decoration: none;
.termpage-window a:hover {
  background-color: #333;

.termpage-menu {
  background-color: #888;

.termpage-menu li:hover {
  background-color: #666;
  cursor: pointer;
You can’t perform that action at this time.
