Extending Guide Index
Why do we need framework extensions?
JitAi provides a rich set of official development frameworks, but in real business scenarios, you may encounter:
- Industry-specific requirements not yet covered by the official framework
- Existing component functionality that's close but needs customization
- Internal enterprise standards requiring unified custom component libraries
Framework extensions are designed to solve these problems, enabling you to build solutions that meet specific requirements on top of the JitAi ecosystem.
Must understand JAAP first
Before extending the JitAi development framework, developers must have a thorough understanding of the JAAP (JitAi AI Application Protocol) specifications, particularly the concepts of Meta, Type, and Instance elements and their relationships. If you intend to override or rewrite the official framework, you'll also need to understand the principles of inheritance and overriding.

Extension types
New extensions
Create entirely new Type elements and their visual editors, suitable for functionality completely absent from the official framework.
Inheritance extensions
Extend and modify existing Type elements while maintaining API compatibility (Liskov Substitution Principle).
Implementation approaches:
- Complete rewrite: Reimplement all logic while maintaining consistent external interfaces
- Incremental modification: Make local adjustments based on existing logic while maintaining interface consistency
Community support
- For issues encountered during extension development, get help through the community forum
- Excellent extension implementations are welcome to be shared with the community for other developers to learn
- Extensions with universal value have the opportunity to be integrated into the official framework
