Foreword
Terminal applications (TUI, Text User Interface) have always had a unique charm — lightweight, fast, and cross-platform. From htop to vim, from the interactive wizard of npm init to database management tools, excellent terminal interfaces can make command-line workflows more efficient.
However, developing a terminal application usually requires dealing directly with low-level rendering details: calculating character buffers, handling ANSI escape sequences, listening for terminal resize events... These tedious tasks often overshadow the business logic itself.
Recently, an Angular adapter for the OpenTUI project has emerged — @cyia/opentui-angular. It allows developers familiar with Angular to build terminal interfaces using the patterns they already know.
OpenTUI itself provides a comprehensive component system (text, box, input, scrollbox, code, diff, etc.) and a set of hooks APIs (keyboard events, focus management, paste handling, timeline animations, etc.), but its design is deeply coupled to React — it relies on react-server-dom-flight to drive the rendering loop.
