Download on the App Store     Get it on Google Play
### Platform-Specific Downloads - macOS / iOS / iPadOS : Search for "Readest" on the [App Store][link-appstore], also available on TestFlight for beta test (send your Apple ID to to request access). - Windows / Linux / Android: Visit [https://readest.com][link-website] or the [Releases on GitHub][link-gh-releases]. - Web: Visit [https://web.readest.com][link-web-readest]. ## Requirements - **Node.js** and **pnpm** for Next.js development - **Rust** and **Cargo** for Tauri development For the best experience to build Readest for yourself, use a recent version of Node.js and Rust. Refer to the [Tauri documentation](https://v2.tauri.app/start/prerequisites/) for details on setting up the development environment prerequisites on different platforms. ```bash nvm install v22 nvm use v22 npm install -g pnpm rustup update ``` ## Getting Started To get started with Readest, follow these steps to clone and build the project. ### 1. Clone the Repository ```bash git clone https://github.com/readest/readest.git cd readest ``` ### 2. Install Dependencies ```bash # might need to rerun this when code is updated git submodule update --init --recursive pnpm install # copy pdfjs-dist to Next.js public directory pnpm --filter @readest/readest-app setup-pdfjs ``` ### 3. Verify Dependencies Installation To confirm that all dependencies are correctly installed, run the following command: ```bash pnpm tauri info ``` This command will display information about the installed Tauri dependencies and configuration on your platform. Note that the output may vary depending on the operating system and environment setup. Please review the output specific to your platform for any potential issues. For Windows targets, “Build Tools for Visual Studio 2022” (or a higher edition of Visual Studio) and the “Desktop development with C++” workflow must be installed. For Windows ARM64 targets, the “VS 2022 C++ ARM64 build tools” and "C++ Clang Compiler for Windows" components must be installed. And make sure `clang` can be found in the path by adding `C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\Llvm\x64\bin` for example in the environment variable `Path`. ### 4. Build for Development ```bash # Start development for the Tauri app pnpm tauri dev # or start development for the Web app pnpm dev-web # preview with OpenNext build for the Web app pnpm preview ``` For Android: ```bash # Initialize the Android environment (run once) pnpm tauri android init pnpm tauri android dev # or if you want to dev on a real device pnpm tauri android dev --host ``` For iOS: ```bash # Set up the iOS environment (run once) pnpm tauri ios init pnpm tauri ios dev # or if you want to dev on a real device pnpm tauri ios dev --host ``` ### 5. Build for Production ```bash pnpm tauri build pnpm tauri android build pnpm tauri ios build ``` ### 6. Setup dev environment with Nix If you have Nix installed, you can leverage flake to enter a development shell with all the necessary dependencies: ```bash nix develop ./ops # enter a dev shell for the web app nix develop ./ops#ios # enter a dev shell for the ios app nix develop ./ops#android # enter a dev shell for the android app ``` ### 7. More information Please check the [wiki][link-gh-wiki] of this project for more information on development. ## Troubleshooting ### 1. Readest Won’t Launch on Windows (Missing Edge WebView2 Runtime) **Symptom** - When you double-click readest.exe, nothing happens. No window appears, and Task Manager does not show the process. - This can affect both the standard installer and the portable version. **Cause** - Microsoft Edge WebView2 Runtime is either missing, outdated, or improperly installed on your system. Readest depends on WebView2 to render the interface on Windows. **How to Fix** 1. Check if WebView2 is installed - Open “Add or Remove Programs” (a.k.a. Apps & features) on Windows. Look for “Microsoft Edge WebView2 Runtime.” 2. Install or Update WebView2 - Download the WebView2 Runtime directly from Microsoft: [link](https://developer.microsoft.com/en-us/microsoft-edge/webview2?form=MA13LH). - If you prefer an offline installer, download the offline package and run it as an Administrator. 3. Re-run Readest - After installing/updating WebView2, launch readest.exe again. - If you still encounter problems, reboot your PC and try again. **Additional Tips** - If reinstalling once doesn’t work, uninstall Edge WebView2 completely, then reinstall it with Administrator privileges. - Verify your Windows installation has the latest updates from Microsoft. **Still Stuck?** - See Issue [readest/readest#358](https://github.com/readest/readest/issues/358) for further details, or head over to our [Discord][link-discord] server and open a support discussion with detailed logs of your environment and the steps you’ve taken. ## Contributors Readest is open-source, and contributions are welcome!
