Papyrus Engine CBZ

Web engine for comic book ZIP archives (.cbz). Pages are loaded lazily from the archive and rendered as images.

Install

npm install @papyrus-sdk/engine-cbz @papyrus-sdk/core @papyrus-sdk/types

Usage

import { CBZEngine } from "@papyrus-sdk/engine-cbz";

const engine = new CBZEngine({ maxCachedPages: 12 });
await engine.load({ type: "comic", source: { uri: "https://example.com/book.cbz" } });

maxCachedPages limits the number of extracted page images kept in memory. The default is 12.

Rust/WASM experiment

The repository also contains @papyrus-sdk/engine-cbz-rust, an experimental adapter that uses the Rust/WASM archive core and falls back to this zip.js implementation if the WASM runtime cannot initialize. The regular CBZEngine remains the stable comparison path.
