hapi vs Koa: What are the differences?
hapi: Server Framework for Node.js. hapi is a simple to use configuration-centric framework with built-in support for input validation, caching, authentication, and other essential facilities for building web applications and services; Koa: 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.
hapi and Koa can be categorized as "Microframeworks (Backend)" tools.
hapi and Koa are both open source tools. It seems that Koa with 26.6K GitHub stars and 2.42K forks on GitHub has more adoption than hapi with 11.3K GitHub stars and 1.16K GitHub forks.
Hazeorid, Beam, and Kanteron Systems are some of the popular companies that use hapi, whereas Koa is used by Hostr, Dial Once, and Pubu. hapi has a broader approval, being mentioned in 58 company stacks & 34 developers stacks; compared to Koa, which is listed in 44 company stacks and 31 developer stacks.
