@tuidom/terminal-backend

The real Node terminal backend for TUIDom: raw-mode tty, double-buffered ANSI diffing, Kitty keyboard protocol, mouse tracking.

⚠️ Experimental — the API is unstable, deep imports expose internals on purpose.

npm install @tuidom/core @tuidom/terminal-backend

import { TuiApplication } from "@tuidom/core/dom/tuiApplication";
import { NodeTerminalBackend } from "@tuidom/terminal-backend/nodeTerminalBackend";

const backend = new NodeTerminalBackend();
const app = new TuiApplication(backend);
// With the Kitty protocol Ctrl+C arrives as an input event, not SIGINT:
backend.onInput((event) => {
    if (event.ctrlKey && event.key === "c") {
        backend.teardown();
        process.exit(0);
    }
});

Environment helpers (isInsideTmux, …) live in @tuidom/terminal-backend/terminalEnv. For in-memory rendering (tests/screenshots) use @tuidom/headless-backend instead.
