Koa vs Nameko: What are the differences?
Developers describe Koa as "Next generation web framework for node.js". Koa aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware. On the other hand, Nameko is detailed as "Python microservices framework". Python microservices framework that leverages AMQP for RPC. It supports asynchronous and synchronous events.
Koa and Nameko can be primarily classified as "Microframeworks (Backend)" tools.
Some of the features offered by Koa are:
- Provides 3 different kinds of functions as middleware
- common function
- async function
On the other hand, Nameko provides the following key features:
- Focus on business logic
- Distributed and scalable
- Extensible
Koa and Nameko are both open source tools. It seems that Koa with 27K GitHub stars and 2.49K forks on GitHub has more adoption than Nameko with 2.98K GitHub stars and 290 GitHub forks.
Which is the best Python framework for microservices?
We are using Nameko for building microservices in Python. The things we really like are dependency injection and the ease with which one can expose endpoints via RPC over RabbitMQ. We are planning to try a tool that helps us write polyglot microservices and nameko is not super compatible with it. Also, we are a bit worried about the not so good community support from nameko and looking for a python alternate to write microservices.
Bottle is much less bloated and fast. Its built-in templating system is one of the fastest as it compiles the templates in bytecode. Also Bottle has no depenencies, preventing dependency bloat.
Pros of Koa
- Async/Await6
- JavaScript5
- REST API1
