Readium Web is a toolkit for building Web Readers. It currently supports EPUB, with plans for PDF, audiobooks and comics/manga/webtoons in future revisions.
This repo is a work in progress, but it will host documentation and project management for the Readium Web project.
Readium Web is divided into two separate toolkits:
- the TypeScript toolkit
- and the Go toolkit
The TypeScript and Go toolkits are meant to be complementary rather than competing toolkits.
The primary use case of the go-toolkit in a Web Reader implementation is to:
- stream packaged resources (EPUB, CBZ)
- output a Readium Web Publication Manifest for each of them over HTTPS
- along with various complementary API responses (Positions List, Guided Navigation)
- and stream individual resources of these publications over HTTPS
Whereas the primary use case of the ts-toolkit in a Web Reader implementation is to:
- interact with a Readium Web Publication Manifest and related APIs
- provide various navigators to handle various publication types (reflowable publications and fixed layout for now)
- along with the lower level API associated to these navigators (for example the Preferences API or Decorator API)
We could say that the go-toolkit turns a publication into an API, whereas the ts-toolkit is the engine of a Web Reader.
In addition to these toolkits, implementers can also build their projects directly on top of Thorium Web and the Readium CLI.
Thorium Web is an open-licensed Web Reader that's built on top of the TypeScript toolkit, providing UI components and all of the features that you would expect from a reading app.
The Readium CLI can stream EPUB publications over HTTP/HTTPS or connect to a storage such as S3, GCS or the local filesystem of a server.
We recommand looking into both projects as your default options when deploying a Web Reader.
Readium Playground is a reference implementation of Thorium Web.
A demo is available at https://playground.readium.org to play with the capabilities of Readium Web and Thorium Web. Unlike a vanilla version of Thorium Web, it also provides various affordances meant to illustrate how implementers can customize the behaviour of a Web Reader.
