How to Use Project IDX

1. Visit the official website of Project IDX (idx.dev), click “Get Started”, and then log in.
2. After logging in, choose to create from a template or import an existing GitHub repository.
3. Fill in the relevant information and wait for IDX to set up the workspace and initialize the development environment.
4. Click the Gemini icon in the upper right corner to explain, chat about, and annotate the code.
5. You can also click the Gemini icon at the bottom to open the Gemini sidebar for a conversation.

The underlying technology behind Project IDX

• Google Cloud Workstations: This serves as the foundation of the IDX workspace, providing powerful virtual machine services that allow resources to be created and scaled on demand. This configuration is not only fast and secure but also highly scalable, enabling flexible adjustment of resources based on development needs.
• AI Models: IDX’s AI features are powered by advanced AI models, Codey and Gemini, which are also used in other Google products such as Studio Bot and Duet. These models are differentiated by their functions. For example, a 12-billion parameter model is used for code completion, while a 24-billion parameter model provides features like streaming conversation and code generation.
• Management Preview: When an IDX workspace is launched, it not only loads the code but also automatically runs a preview environment (if applicable). The preview server runs on a virtual machine, allowing developers to start modifying the code immediately after the workspace is created and see the “hot reload” effects in real time in the preview.
• Environment Setup: The IDX workspace utilizes Docker containers provided by Google Cloud Workstations. These containers are pre-installed with various system software required to run services, such as Supervisor and other task scheduling tools, as well as other custom scripts like the preview server.
• Service Account-Based Authentication: To ensure security, IDX enables secure connections between the VM and other services through service accounts. Each workspace has a unique service account with strictly controlled permissions, allowing communication only with authorized services. A custom metadata server on the VM is responsible for securely managing these access permissions.
• Nix: To support diverse development needs, IDX adopts Nix as its package management and build system. Nix provides features such as high reproducibility, atomic upgrades and rollbacks, isolation, sandboxing, as well as robust package version control and conflict resolution capabilities. With Nix, IDX can provide developers with a consistent and predictable build environment while reducing the complexity of learning new configuration languages.
