xterm.js Development Skill
Expert guidance for building, configuring, and integrating xterm.js terminal emulators in web and Electron applications. Use this skill whenever the user mentions xterm, xterm.js, @xterm/xterm, terminal emulator in the browser, web terminal, WebSSH, in-browser shell, or asks about addons like FitAddon, WebglAddon, SearchAddon, AttachAddon, or integration with node-pty. Also trigger for questions about ANSI/VT sequences, terminal theming, PTY over WebSocket, custom key handlers, parser hooks, or embedding a terminal in React/Vue/Angular/Electron apps. TRIGGER WHEN: the user mentions xterm, xterm.js, @xterm/xterm, terminal emulator in the browser, web terminal, WebSSH, in-browser shell, or asks about addons like FitAddon, WebglAddon, SearchAddon, AttachAddon, or integration with node-pty. DO NOT TRIGGER WHEN: the user wants a native OS terminal (not browser-based) or a non-xterm terminal library (e.g. VT100 emulator in Python).
