Moleculer: Open-Source Microservices Framework for Node.js
Moleculer is an open-source microservices framework for Node.js. It helps developers organize application logic into self-contained services that can communicate with each other. Key features include service discovery, fault tolerance, load balancing, middleware, and metrics.
What is Moleculer?
Moleculer is an open-source microservices framework for Node.js applications. It aims to help developers break down complex, monolithic codebases into independent microservices that can scale and evolve separately.
Some key features and benefits of Moleculer:
- Service discovery - Automatic service registry and lookup helps services find and talk to each other.
- Fault tolerance - Built-in retry, timeout, and circuit breaker handling makes services resilient.
- Load balancing - Requests are distributed across service instances.
- Middleware - Extensible middleware system for cross-cutting concerns like logging, metrics, authentication etc.
- Metrics and monitoring - Metrics exporter to track service performance and health.
- Supports multiple transports - Works over HTTP, NATS, MQTT, Redis etc.
- API gateway - Development gateway proposes a public API gateway.
- Originally created by Icebob and now maintained by the open-source community.
Moleculer promotes a microservice architecture with decoupled services that can be developed, deployed and scaled independently. Its modular and extensible nature makes it apt for modern distributed applications.
