Moleculer is a fast, progressive microservices framework for Node.js that helps build efficient, reliable, and scalable distributed services. It provides built-in service discovery, load balancing, fault tolerance, caching, and pluggable transporters, serializers, and loggers.
Use cases
- build microservices in Node.js
- set up service discovery and a service registry
- implement request-reply and event-driven communication between services
- add circuit breaker, retry, and timeout fault tolerance to distributed services
- build an API gateway in front of microservices
- load balance requests and events across service nodes
- add metrics and distributed tracing to services
- connect services over NATS, MQTT, Kafka, Redis, or AMQP
When to choose
- you are building a microservices architecture in Node.js
- you need built-in service discovery, load balancing, and fault tolerance without extra infrastructure
- you want pluggable transporters and serializers to fit your existing messaging stack
- you need a master-less, scalable distributed system with metrics and tracing out of the box
When to avoid
- you are building a small monolith where a simple web framework suffices
- your team is not using Node.js or JavaScript
- you need a framework with a guaranteed 1.0 stable API, since pre-1.0 minor versions may include breaking changes
- you require a framework with a large corporate backing rather than a community-driven project
