# Frequently Asked Questions
|
|
|
|
## Does Koa replace Express?
|
|
|
|
It's more like Connect, but a lot of the Express goodies
|
|
were moved to the middleware level in Koa to help form
|
|
a stronger foundation. This makes middleware more enjoyable
|
|
and less error-prone to write, for the entire stack, not
|
|
just the end application code.
|
|
|
|
Typically many middleware would
|
|
re-implement similar features, or even worse incorrectly implement them,
|
|
when features like signed cookie secrets among others are typically application-specific,
|
|
not middleware specific.
|
|
|
|
## Does Koa replace Connect?
|
|
|
|
No, just a different take on similar functionality
|
|
now that generators allow us to write code with less
|
|
callbacks. Connect is equally capable, and some may still prefer it,
|
|
it's up to what you prefer.
|
|
|
|
## Do Generators Decrease Performance?
|
|
|
|
Barely - check out the benchmarks in our readme, the numbers
|
|
are more than fine, and there's no substition for proper
|
|
horizontal scaling. |
