    The Lura Project framework

    The Lura Project framework

    Ultra performant API Gateway with middlewares

    An extendable, simple and stateless high-performance API Gateway framework designed for both cloud-native and on-prem setups.

This is of course a good practice, but the UI consumers need to do implementations that suffer a lot of complexity and burden with the sizes of their microservices responses. Lura is an API Gateway builder and proxy generator that sits between the client and all the source servers, adding a new layer that removes all the complexity to the clients, providing them only the information that the UI needs. ...
