xterm.js is a TypeScript-based front-end terminal emulation component that lets web applications embed fully-featured terminal interfaces. It powers in-browser terminals in tools like VS Code and browser IDEs. Xterm.js works with most terminal apps such as bash, vim, and tmux, including support for curses-based apps and mouse events. Xterm.js is really fast, it even includes a GPU-accelerated renderer. Xterm.js is not a terminal application that you can download and use on your computer. Xterm.js is not bash. Xterm.js can be connected to processes like bash and let you interact with them (provide input, receive output).
