Shared Protocol Buffer definitions for Nexus microservices

Nexus Proto

Shared Protocol Buffer definitions for Nexus microservices.

Why "Nexus"?

The name Nexus was chosen to represent the central connection between microservices. In many languages, "nexus" refers to a point of intersection or link, which is exactly what this project provides: an efficient hub for communication between distributed services built in different technologies. The idea is to create a convergence point that makes it easier to integrate systems, ensuring consistent and scalable communication, no matter the language or framework used. Nexus is the solution that connects and unites services in a simple and effective way.

Features

• Centralized Protocol Definitions: All communication contracts are defined in a shared repository of .proto files.
• Pre-Generated Python Stubs: Python stubs (*_pb2.py and *_pb2_grpc.py) are automatically generated and included in the package, eliminating the need for consumers to generate them.
• Multi-Language Support: Easily integrate microservices written in different programming languages (e.g., Python, Node.js, Java, etc.).
• Scalable Communication: Easily extend the system as new microservices are added to the architecture.
• gRPC-powered: Leveraging gRPC for high-performance communication with built-in support for multiple programming languages.
• Industry Standard: Follows best practices from projects like googleapis-common-protos, ensuring consistency and reliability.

Installation

Node.js / npm

npm install @keeps-learn/nexus-proto

📦 npm Package: https://www.npmjs.com/package/@keeps-learn/nexus-proto

Python / pip

pip install keeps-learn-nexus-proto

📦 PyPI Package: https://pypi.org/project/keeps-learn-nexus-proto/

Quick Start - Python

Using Pre-Generated Stubs (Recommended)

# Import stubs directly - no compilation needed!
from nexus_proto.generated.myaccount import users_pb2, users_pb2_grpc
from nexus_proto.generated.konquest import mission_pb2, mission_pb2_grpc

# Use message types
user = users_pb2.User(id="123", name="John Doe")

# Use service stubs with gRPC
import grpc
channel = grpc.aio.secure_channel('localhost:50051', grpc.ssl_channel_credentials())
stub = users_pb2_grpc.UserServiceStub(channel)

See USAGE.md for more detailed examples and options.
