@jsvision/core

The foundation engine of the jsvision SDK for building classic terminal (TUI) applications in TypeScript: capability detection & auto-config, a pure byte→event input decoder, a width-correct rendering engine with a pure damage-diff serializer, depth-aware colour encoding, a native tty host with guaranteed restore on every exit path, and a safety layer (essentials gate, sanitize boundary, typed errors).

ESM-only, zero runtime dependencies, Node ≥ 22.

npm install @jsvision/core

import { resolveCapabilities, ScreenBuffer, serialize } from '@jsvision/core';
