Specifically the latest versions of *Chrome*, *Edge*, *Firefox* and *Safari*. + +We also partially support *Intenet Explorer 11*, meaning xterm.js should work for the most part, but we reserve the right to not provide workarounds specifically for it unless it's absolutely necessary to get the basic input/output flow working. + +Xterm.js works seamlessly in [Electron](https://electronjs.org/) apps and may even work on earlier versions of the browsers, these are the versions we strive to keep working. + +## API + +The full API for xterm.js is contained within the [TypeScript declaration file](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts), use the branch/tag picker in GitHub (`w`) to navigate to the correct version of the API. + +Note that some APIs are marked *experimental*, these are added to enable experimentation with new ideas without committing to support it like a normal [semver](https://semver.org/) API.

custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This this is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingCodepoint: number;\n\n // buffers over several parse calls\n protected _params: Params;\n protected _collect: number;\n\n // handler lookup containers\n protected _printHandler: PrintHandlerType;\n protected _executeHandlers: {[flag: number]: ExecuteHandlerType};\n protected _csiHandlers: IHandlerCollection;\n protected _escHandlers: IHandlerCollection;\n protected _oscParser: IOscParser;\n protected _dcsParser: IDcsParser;\n protected _errorHandler: (state: IParsingState) => IParsingState;\n\n // fallback handlers\n protected _printHandlerFb: PrintFallbackHandlerType;\n protected _executeHandlerFb: ExecuteFallbackHandlerType;\n protected _csiHandlerFb: CsiFallbackHandlerType;\n protected _escHandlerFb: EscFallbackHandlerType;\n protected _errorHandlerFb: (state: IParsingState) => IParsingState;\n\n constructor(readonly TRANSITIONS: TransitionTable = VT500_TRANSITION_TABLE) {\n super();\n\n this.initialState = ParserState.GROUND;\n this.currentState = this.initialState;\n this._params = new Params();

It's used by popular projects such as VS Code, Hyper and Theia.\n\n## Features\n\n- **Terminal apps just work**: Xterm.js works with most terminal apps such as `bash`, `vim` and `tmux`, this includes support for curses-based apps and mouse event support.\n- **Performant**: Xterm.js is *really* fast, it even includes a GPU-accelerated renderer.\n- **Rich unicode support**: Supports CJK, emojis and IMEs.\n- **Self-contained**: Requires zero dependencies to work.\n- **Accessible**: Screen reader and minimum contrast ratio support can be turned on\n- **And much more**: Links, theming, addons, well documented API, etc.\n\n## What xterm.js is not\n\n- Xterm.js is not a terminal application that you can download and use on your computer.\n- Xterm.js is not `bash`. Xterm.js can be connected to processes like `bash` and let you interact with them (provide input, receive output).\n\n## Getting Started\n\nFirst you need to install the module, we ship exclusively through [npm](https://www.npmjs.com/) so you need that installed and then add xterm.js as a dependency by running:\n\n```\nnpm install xterm\n```\n\nTo start using xterm.js on your browser, add the `xterm.js` and `xterm.css` to the head of your html page. Then create a `
` onto which xterm can attach itself. Finally instantiate the `Terminal` object and then call the `open` function with the DOM object of the `div`.\n\n```html\n\n \n \n \n \n \n \n
\n \n \n \n```\n\n### Importing\n\nThe recommended way to load xterm.js is via the ES6 module syntax:\n\n```javascript\nimport { Terminal } from 'xterm';\n```\n\n### Addons\n\n⚠️ *This section describes the new addon format introduced in v3.14.0, see [here](https://github.com/xtermjs/xterm.js/blob/3.14.2/README.md#addons) for the instructions on the old format*\n\nAddons are separate modules that extend the `Terminal` by building on the [xterm.js API](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts). To use an addon you first need to install it in your project:\n\n```bash\nnpm i -S xterm-addon-web-links\n```\n\nThen import the addon, instantiate it and call `Terminal.loadAddon`:\n\n```ts\nimport { Terminal } from 'xterm';\nimport { WebLinksAddon } from 'xterm-addon-web-links';\n\nconst terminal = new Terminal();\n// Load WebLinksAddon on terminal, this is all that's needed to get web links\n// working in the terminal.\nterminal.loadAddon(new WebLinksAddon());\n```\n\nThe xterm.js team maintains the following addons but they can be built by anyone:\n\n- [`xterm-addon-attach`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-attach): Attaches to a server running a process via a websocket\n- [`xterm-addon-fit`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-fit): Fits the terminal to the containing element\n- [`xterm-addon-search`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-search): Adds search functionality\n- [`xterm-addon-web-links`](https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-web-links): Adds web link detection and interaction\n\n## Browser Support\n\nSince xterm.js is typically implemented as a developer tool, only modern browsers are supported officially. Specifically the latest versions of *Chrome*, *Edge*, *Firefox* and *Safari*.\n\nWe also partially support *Intenet Explorer 11*, meaning xterm.js should work for the most part, but we reserve the right to not provide workarounds specifically for it unless it's absolutely necessary to get the basic input/output flow working.\n\nXterm.js works seamlessly in [Electron](https://electronjs.org/) apps and may even work on earlier versions of the browsers, these are the versions we strive to keep working.\n\n## API\n\nThe full API for xterm.js is contained within the [TypeScript declaration file](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts), use the branch/tag picker in GitHub (`w`) to navigate to the correct version of the API.\n\nNote that some APIs are marked *experimental*, these are added to enable experimentation with new ideas without committing to support it like a normal [semver](https://semver.org/) API. Note that these APIs can change radically between versions so be sure to read release notes if you plan on using experimental APIs.\n\n## Real-world uses\nXterm.js is used in several world-class applications to provide great terminal experiences.\n\n- [**SourceLair**](https://www.sourcelair.com/): In-browser IDE that provides its users with fully-featured Linux terminals based on xterm.js.\n- [**Microsoft Visual Studio Code**](http://code.visualstudio.com/): Modern, versatile and powerful open source code editor that provides an integrated terminal based on xterm.js.\n- [**ttyd**](https://github.com/tsl0922/ttyd): A command-line tool for sharing terminal over the web, with fully-featured terminal emulation based on xterm.js.\n- [**Katacoda**](https://www.katacoda.com/): Katacoda is an Interactive Learning Platform for software developers, covering the latest Cloud Native technologies.\n- [**Eclipse Che**](http://www.eclipse.org/che): Developer workspace server, cloud IDE, and Eclipse next-generation IDE.\n- [**Codenvy**](http://www.codenvy.com): Cloud workspaces for development teams.\n- [**CoderPad**](https://coderpad.io): Online interviewing platform for programmers.
