@tuishot/node

In-process Node-API rendering for tuishot. It parses ANSI with the same Alacritty terminal model as the native CLI and can render an existing validated tuishot grid. It never starts the CLI or a PTY.

import { renderAnsi } from "@tuishot/node";

const { png, svg, txt, json } = renderAnsi("\x1b[31mhello\x1b[0m\nworld", {
  cols: 40,
  rows: 4,
});

renderAnsi treats bare LF as a newline at column zero, matching static output from Ink's renderToString. Existing CRLF is preserved. Rendering uses the bundled JetBrains Mono font only, so repeated output is byte-stable across supported hosts. Static ANSI dimensions are limited to 1,000,000 cells to bound in-process allocation before parsing.

The package supports Node.js 18 and newer. Native addons are installed through one of eight platform-specific optional packages. To bound native allocations, ANSI and Grid inputs are limited to 1,000,000 cells; Grid symbol text is limited to 16 MiB in aggregate.
