Notadd Logo.



Notadd is an open source, Nest.js framework-based microservice development architecture that allows you to build a microservices system using the right modules and addons for different business needs. Notadd officially provides an abstract public service layer. Within the service layer, each module provides the Grpc interface for the Notadd main program to call. For example, a CMS system, you can use the officially provided nt-module-cms and nt-module-user modules as the underlying service layer. Then use the Notadd main program to write your API layer code according to the protobuf message protocol defined by the service layer.
