How to Install DejaOS

📦 Runtime Environment​

DejaOS is a JavaScript runtime designed for embedded devices. No manual installation is required—all devices we provide come with DejaOS pre-installed and ready to use out of the box.

  3. DejaOS IDE Extension
    This is a VSCode extension. Search for DejaOS IDE in the VSCode Extensions Marketplace, or install directly via:

⚠️ System Support​

Currently, the development environment only supports Windows.
macOS and Linux are not yet supported.

🌐 Network Requirements​

During development, DejaOS IDE may need to download official JavaScript modules:

  • Online Development: Access the DejaOS module repository to fetch the latest modules and dependencies.
  • Offline Development: Previously downloaded modules are cached locally, allowing continued development without an internet connection.

We recommend staying online to ensure you always have access to the latest modules.
