The terminal emulator is a venerable but essential tool for everyone using the command line. There are so many terminal emulators available for Linux that the choice is, frankly, bamboozling. This article looks at Hyper, one of the newer terminal emulators available. It’s built with web technologies – JavaScript, HTML, CSS. The goal of the project is to create a beautiful and extensible experience for command-line interface users, built on open web standards. Hyper is based on xterm.js, a front-end component written in TypeScript.
