Can I use ElysiaJS for WebSocket endpoints and real-time backend routing?

Yes, ElysiaJS supports WebSocket endpoints alongside standard API routing. You can establish real-time backend connections while maintaining type-safe communication between the server and connected clients.

What do I need to set up an ElysiaJS backend environment?

To set up an ElysiaJS backend environment, you need a modern JavaScript or TypeScript runtime like Node or Bun. Scaffold a new project using the command line to generate the initial server structure.

How does ElysiaJS handle API authentication and validation?

ElysiaJS handles API authentication and validation by applying type-safe schemas to routes. This enforces strict request data validation and secures backend endpoints through integrated authentication patterns.

Does ElysiaJS provide OpenAPI integration for backend API design?

Yes, ElysiaJS provides OpenAPI integration to streamline API ecosystems. It generates API documentation and works with Eden Treaty to offer external integrations for type-safe client-server communication.

What are the best practices for ElysiaJS production deployment?

Best practices for ElysiaJS production deployment involve using real-world patterns for testing and API design. Apply production deployment strategies to scale your type-safe backend efficiently in a modern runtime.
