Rails API vs Moleculer: What are the differences?
What is Rails API? Rails for API only applications. Rails::API is a subset of a normal Rails application, created for applications that don't require all functionality that a complete Rails application provides. It is a bit more lightweight, and consequently a bit faster than a normal Rails application. The main example for its usage is in API applications only, where you usually don't need the entire Rails middleware stack nor template generation.
What is Moleculer? Fast & powerful microservices framework for NodeJS. It is a fault tolerant framework. It has built-in load balancer, circuit breaker, retries, timeout and bulkhead features. It is open source and free of charge project.
Rails API and Moleculer can be categorized as "Microframeworks (Backend)" tools.
Rails API and Moleculer are both open source tools. Rails API with 5.26K GitHub stars and 294 forks on GitHub appears to be more popular than Moleculer with 2.85K GitHub stars and 252 GitHub forks.
