   4
   5 Xterm.js is a terminal front-end component written in JavaScript that works in the browser.
   6
   7 It enables applications to provide fully featured terminals to their users and create great development experiences.
   8
   9 ## Features
  10 - **Text-based application support**: Use xterm.js to work with applications like `bash`, `git` etc.
  11 - **Curses-based application support**: Use xterm.js to work with applications like `vim`, `tmux` etc.
  12 - **Mouse events support**: Xterm.js captures mouse events like click and scroll and passes them to the terminal's back-end controlling process
  13 - **CJK (Chinese, Japanese, Korean) character support**: Xterm.js renders CJK characters seamlessly
  14 - **IME support**: Insert international (including CJK) characters using IME input with your keyboard
  15 - **Self-contained library**: Xterm.js works on its own. It does not require any external libraries like jQuery or React to work
  16 - **Modular, event-based API**: Lets you build addons and themes with ease
  17
  18 ## What xterm.js is not
  19 - Xterm.js is not a terminal application that you can download and use on your computer
  20 - Xterm.js is not `bash`. Xterm.js can be connected to processes like `bash` and let you interact with them (provide input, receive output)
  21

  49 ## Browser Support
  50
  51 Since xterm.js is typically implemented as a developer tool, only modern browsers are supported officially. Here is a list of the versions we aim to support:
  52
  53 - Chrome 48+
  54 - Edge 13+
  55 - Firefox 44+
  56 - Internet Explorer 11+
  57 - Opera 35+
  58 - Safari 8+
  59
  60 Xterm.js works seamlessly in Electron apps and may even work on earlier versions of the browsers but these are the browsers we strive to keep working.
  61
  62 ## Demo
  63
  64 ### Linux or macOS
  65
  66 Run the following commands:
  67
  68 ```
  69 $ npm install
  70 $ npm start
  71 ```
  72
  73 Then open http://0.0.0.0:3000 in a web browser.
  74
  75 ### Windows
  76
  77 First, ensure [node-gyp](https://github.com/nodejs/node-gyp) is installed and configured correctly, then run these commands.
  78
  79 Note: Do not use ConEmu, as it seems to break the demo for some reason.
  80
  81 ```
  82 > npm install
  83 > npm start
  84 ```
  85
  86 Then open http://127.0.0.1:3000 in a web browser.
  87
  88 ## Getting Started
  89
  90 To start using xterm.js on your browser, add the `xterm.js` and `xterm.css` to the head of your html page. Then create a `<div id="terminal"></div>` onto which xterm can attach itself.
  91 ```html
  92 <!doctype html>
  93   <html>
  94     <head>
  95       <link rel="stylesheet" href="bower_components/xterm.js/dist/xterm.css" />
  96       <script src="bower_components/xterm.js/dist/xterm.js"></script>
  97     </head>
  98     <body>
  99       <div id="terminal"></div>
 100       <script>
 101         var term = new Terminal();
 102         term.open(document.getElementById('terminal'));
 103         term.write('Hello from \033[1;3;31mxterm.js\033[0m $ ')
 104       </script>
 105     </body>
 106   </html>
 107 ```
 108 Finally instantiate the `Terminal` object and then call the `open` function with the DOM object of the `div`.
 109
 110 ## Addons
 111
 112 Addons are JavaScript modules that attach functions to the `Terminal` prototype to extend its functionality. There are a handful available in the main repository in the `dist/addons` directory, you can even write your own (though they may break when the internals of xterm.js change across versions).
 113
 114 To use an addon, just include the JavaScript file after xterm.js and before the `Terminal` object has been instantiated. The function should then be exposed on the `Terminal` object:
 115
 116 ```html
 117 <script src="node_modules/dist/xterm.js"></script>
 118 <script src="node_modules/dist/addons/fit/fit.js"></script>
 119 ```
 120
 121 ```js
 122 var xterm = new Terminal();
 123 // init code...
 124 xterm.fit();
 125 ```
 126
 127 ## Releases
 128
 129 Xterm.js follows a monthly release cycle roughly.
 130
 131 The existing releases are available at this GitHub repo's [Releases](https://github.com/sourcelair/xterm.js/releases), while the roadmap is available as [Milestones](https://github.com/sourcelair/xterm.js/milestones).
 132
 133 ## Development and Contribution
 134
 135 Xterm.js is maintained by [SourceLair](https://www.sourcelair.com/) and a few external contributors, but we would love to receive contributions from everyone!
 136
 137 To contribute either code, documentation or issues to xterm.js please read the [Contributing document](CONTRIBUTING.md) beforehand. The development of xterm.js does not require any special tool. All you need is an editor that supports JavaScript/TypeScript and a browser. You will need Node.js installed locally to get all the features working in the demo.
