Brass Lantern for Vue

@brass-lantern/vue: the CRT terminal as a component and mountGame, with five themes, on top of @brass-lantern/engine.

Install

npm i @brass-lantern/engine @brass-lantern/vue vue pinia

Needs vue 3.5 or later and pinia 4. The Z-machine interpreter (ifvms) comes with it.

Use

import { mountGame } from '@brass-lantern/vue';
import '@brass-lantern/vue/style.css';
import { tutorial } from '@brass-lantern/engine/worlds';

mountGame('#app', {
  cartridges: [{ kind: 'world', id: 'snack-attack', title: 'SNACK ATTACK', world: tutorial }],
  storagePrefix: 'my-game',   // saves, transcripts and the player's theme live under this
  theme: 'crt-green',         // optional: crt-amber (default), crt-green, simple, simple-light, simple-dark
});

Under TypeScript 6, the .css import needs Vite’s client types (vite/client) or a declare module '*.css'; somewhere in your project. The game fills its container and touches nothing else on the page, so give the container a size (for a full-screen game, html, body, #app { height: 100%; margin: 0; overflow: hidden; }). Pass autofocus: false to a game embedded in a longer page.

Prefer a component? <BrassLantern :options="options" /> takes the same options. The package exports BrassLantern, mountGame, ConsentBanner, the themes (PRESETS, PALETTES, resolveTheme, UnknownTheme), useTypewriter, the GameOptions and GameEvent types, and the cartridge types (Cartridge, WorldCartridge, ZCodeCartridge); the rest is internal. Two games on one page need different storagePrefix values.

Players can type THEME, BLOOM ON|OFF and EFFECTS ON|OFF, at the menu, in native worlds and in story files; the choice is remembered in the browser. Every option, custom themes and the intent server are in the guide.
