Thorium Reader

Thorium Reader is an easy to use EPUB reading application for Windows 10/10S, MacOS and Linux. After importing e-books from a directory or OPDS feed, you'll be able to read on any screen size, customize layout settings, navigate via the table of contents or page list, set bookmarks ... A great care is taken to ensure the accessibility of the application for visual impaired people using NVDA, JAWS or Narrator.

Free application. No ads. No private data flowing anywhere.

This project is in constant evolution, corrections and new features will be added soon and your support is welcome for that. The application is based on the open-source Readium Desktop toolkit.

Prerequisites

  1. NodeJS 18 (check with node --version)
  2. NPM 9 (check with npm --version)

Technologies

  • typescript
  • electron
  • reactjs
  • redux
  • saga
  • i18next

Quick start

Install dependencies

  • npm install (or npm ci): initialize local node_modules packages from dependencies declared in package.json (this will also automatically call a long-running compilation stage in npm run postinstall)
  • in case of failure to NPM "install" because of "Divina player" SHA integrity mismatch, please try running the following command in your shell: node scripts/package-lock-patch.js && cat package-lock.json | grep -i divina-player-js

Start application in development environment

(with hot-reload dev server, web inspectors / debuggers)

  • npm run start:dev (or npm run start:dev:quick to bypass TypeScript checks / launch the app faster)

Start application in production environment

  • npm start (or npm run start)

Build installers

  • npm run package:win or npm run package:mac or npm run package:linux

[DEV] Architecture

Thorium-reader is composed of 3 parts:

  • One node.js main process (electron back-end)
  • One library window (chromium renderer)
  • One to N reader window(s) (chromium renderer)

Each part runs a model-controller and a view for the renderer process.

  • the model is a state container with Redux. It's based on flux architecture
  • the controller is a middleware from Redux named Redux-saga. It handles all side effects and application behaviour.
  • the view for the rendering is React with class components

To link these 3 parts we use:

API Concept

To have a POST request from a renderer process to the main process, we use the notion of API. It's not an http API but an RPC encapsuled one, to redux/redux-saga logic with Action and Reducer.

Here is a diagram of the communication:

api

Src:

  • src/main/redux/sagas/api/api.ts
  • src/common/redux/actions/api/index.ts
  • src/renderer/common/redux/reducers/api.ts

At the moment there are 17 API endpoints from (src/main/redux/sagas/api):

library:

  • apiapp:
    • apiapp/search : search a library from apiapp protocol
  • browser:
    • httpbrowser/browse : browse and parse an opds URL
  • opds:
    • opds/getFeed : get an opdsFeed with its identifier
    • opds/findAllFeed: get all opdsFeed saved
    • opds/deleteFeed: delete an opdsFeed with its identifier
    • opds/addFeed: add an opdsFeed
    • opds/getUrlWithSearchLinks: get the search URL from an opdsFeed
  • publication: (src/common/api/interface/publicationApi.interface.ts)
    • publication/get: get a publicationView from id
    • publication/delete: delete a publicationView from id
    • publication/findAll: get all publicationView
    • publication/findByTag: get all publicationView from a specific tag string
    • publication/updateTags: update tags list from a publication
    • publication/importFromLink: import a publication from an URL
    • publication/importFromFs: import a publication from a fileSystem path
    • publication/search: search publication from a query text
    • publication/searchEqTitrle: search publication by title matching
    • publication/exportPublication: export publication to the fileSystem
