End-to-end type-safety refers to a system in which every component of the system is checked for type consistency, meaning that data is passed between components only if the types of the data are compatible.
This can help prevent bugs and errors by catching type mismatches early in the development process, rather than at runtime.
It ensures that the system is working in a predictable way, thus reducing the risk of unexpected behavior.
Elysia supports End-to-End Type-Safety between client-server with the Eden plugin.
Hover over variable and function to see type definition.
Elysia allows you change the type on server and it will be instantly reflected on the client, helping with auto-completion and type-enforcement.
See Eden for more examples.
