🎉 Add Koa as additional web layer

[rubek-joshi]

A Koa-lity Web Layer

Koa was written by the same guys who worked on Express and has grown to become the most popular alternative to Express.

1. Popularity

It has grown to become the most popular alternative to Express.

You can view the updated chart here.

2. Lightweight

Koa is very lightweight, with just ~1854 lines of code.

Same source as above image.

3. Performance

It is fast, not the fastest but still quite fast. While Fastify clearly wins this category, Koa offers much more than Fastify. (see below)

Other Notable Reasons

• No more callbacks, facilitating an upstream and downstream flow of control.
• Better error handling through try/catch.
• Cleaner, more readable async code.
• Koa improves interoperability, robustness, and makes writing middleware much more enjoyable.
• Has a large number of helpful methods but maintains a small footprint, as no middleware are bundled.
• A great eco-system.

Footnote

I genuinely think Koa should be a candidate to serve as the recommended web layer. I've used Express (extensively), Fastify (briefly) and Koa which in my personal opinion provided me with the best developer experience. It also powers Strapi.
