vs. HAPI, Koa, and others - mmedrano9438/peripheral-brain GitHub Wiki

Hapi:

• hapi slightly newer than express
• a bit boilerplate-heavy for small projects
• favours configuration over code

////////

Express:

• aims to provide developers with a simple, performant, and unopinionated toolset for creating web application servers.
• API is kept lightweight and maintains a high degree of consistency with the NodeJS core API
• requires outside modules

///////

Koa:

• new web framework designed by the team behind Express
• smaller, more expressive, and more robust foundation for web applications and APIs vs Express
• does not bundle any middleware within its core, making it faster than others.
