How can I migrate my Express.js application to another framework?
Migrating from Express.js involves several steps. Which framework are you considering?
I'm thinking about switching to Koa. What should I keep in mind?
Koa is a great choice! You'll need to adjust middleware usage since Koa uses async functions. Are you familiar with that?
Not really. Can you explain how middleware works in Koa?
Sure! In Koa, middleware is composed using async functions. Each middleware can either end the response or pass control to the next one using 'await next()'.
Got it! What about routing? How does it differ from Express?
Koa doesn't come with a built-in router, so you'll need to use a third-party router like 'koa-router'. It offers similar functionality but requires some setup.
