Source Code & Build Instructions
This plugin contains minified/compiled React assets under the dist/ directory. For build reproducibility and compilation transparency, the distributed package includes the complete, unminified, human-readable source code inside the src/ directory, as well as the build configuration files (package.json, package-lock.json, vite.config.ts, tsconfig.json, postcss.config.js, tailwind.config.ts). The source code is also publicly accessible and maintained in the following repository:
https://github.com/mehdituran/jetreader-lite
Build Tools & Steps
To build the compiled assets from the source code:
1. Ensure Node.js (v18+) is installed.
2. Clone the repository and navigate to the project directory.
3. Install dependencies by running:
npm install
4. Build the production assets using the Vite builder:
npm run build
5. The generated compiled files will be output to the dist/ directory.
Third-Party Libraries
The compiled assets bundle the following third-party libraries:
* React & React DOM (MIT License) – https://react.dev/
* TanStack React Query (MIT License) – https://tanstack.com/query/

Localization & Translation
JetReader is fully translation-ready: PHP strings use WordPress i18n functions (__(), _e(), etc.) and the React admin/frontend/reader interfaces use @wordpress/i18n, so the plugin follows your site’s active language (including per-page languages set by Polylang/WPML) automatically. The translation template is at languages/jetreader.pot.
Installation
- Upload the
jetreaderfolder to the/wp-content/plugins/directory, or install directly via Plugins → Add New → Upload Plugin. - Activate the plugin through the Plugins menu.
- Upon activation, the plugin will automatically create custom database tables and register the default CPT rewrite rules.
- Go to JetReader → Settings to set your default language, reader options, library card layout, and color palettes.
- Create a new WordPress Page, insert the
[jetreader_library]shortcode, and publish it. - Add your first digital item via JetReader → Library Items → Add New or by uploading documents. Your library is now ready!
Frequently asked questions
Which file formats are supported?
JetReader supports EPUB, PDF, TXT, and DOCX files. Files can be uploaded directly or linked via external URLs.
Can visitors bookmark or highlight without registering?
No. Since bookmarks and annotations are saved in your database for a persistent cross-device experience, users must be logged into a WordPress account. Public reading does not require an account.
Can I disable text copying?
Yes. Go to JetReader → Settings and toggle the “Copy Enabled” permission. This disables text selection, right-click, and copy hotkeys inside the reader interface.
How does search work in the Lite version?
JetReader allows visitors to search through uploaded documents in the library by their titles. For document-internal content search, the reader parses and searches document text directly in the visitor’s browser (client-side), without requiring any server-side database indexing.
Will JetReader slow down my WordPress site?
No. Frontend assets (JavaScript and CSS bundles) are enqueued dynamically and only load on pages where a JetReader shortcode is present.
Is JetReader compatible with WooCommerce?
Yes. JetReader declares compatibility with WooCommerce High-Performance Order Storage (HPOS) so no admin compatibility warnings appear on WooCommerce stores.
What are Tags used for?
Tags are a lightweight cross-type taxonomy. Unlike categories (which are content-type specific), a single tag can group books, articles, magazines, and Q&A documents together. This enables flexible filtering and discovery across your entire library.
How do I add screenshots to a WordPress.org plugin page?
See the Screenshots section below for the required images and how to place them.
Changelog
Initial stable release. Thank you for using JetReader!
1.1.1
- Fixed: activating JetReader Pro while Lite was active could trigger a “Cannot redeclare function” fatal error instead of cleanly handing off to Pro. The shared activation/deactivation functions now load through a separate include file so the Lite/Pro conflict guard can prevent the redeclaration as intended.
- Updated documentation, support, and plugin URIs to https://rikny.com.
1.1.0
- Localization: replaced the custom
lang/*.json+t()translation system with native WordPress i18n (__(),_e(),sprintf()) across PHP and the React admin/frontend/reader interfaces, so the plugin is now translatable through standard.po/.mofiles and works correctly with Polylang/WPML. - The plugin’s text direction (RTL/LTR) now follows WordPress’s own
is_rtl()instead of a custom per-language setting. - Removed the unused “Plugin Language” backend setting and the
lang/directory; admin menu and CPT labels are now translated through core WordPress functions instead of a custom JSON lookup. - Regenerated
languages/jetreader.potto include all translatable strings from both PHP and the React/TypeScript source.
1.0.3
- Security: file rename endpoint now rejects any new file name that changes the file extension, preventing uploads from being renamed to executable file types.
- Fixed: critical reader page CSS is now registered through
wp_register_style()/wp_add_inline_style()instead of being printed as an inline<style>tag. - Fixed: rate-limit transient keys now use the
jetreader_prefix instead of the too-shortjr_prefix to avoid collisions with other plugins.
1.0.2
- Collapsible Filter Sidebar: added a collapsible Filter Sidebar on desktop layout.
- Modern Arrow Icons: integrated custom
<and>toggle buttons for the sidebar.
1.0.1
- Custom Q&A layout: displayed as a clean, vertical list instead of standard grid cards.
- Detail modal: hid the left cover image column and adjusted width to 650px for Q&A items.
- Multiple shortcodes: fixed ID conflicts to support displaying multiple library instances on a single page.
- Type parameter mapping: automatically resolves plural shortcode attributes (e.g. books, magazines) to singular ones.

- Added support for EPUB, PDF, TXT, and DOCX files.
