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:

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.

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.

FAQ
-
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.
-
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
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.
