 # Middleware
 
-You’ve seen middleware in action in the [Async Actions](../advanced/AsyncActions.md) example. If you’ve used server-side libraries like [Express](http://expressjs.com/) and [Koa](http://koajs.com/), you were also probably already familiar with the concept of *middleware*. In these frameworks, middleware is some code you can put between the framework receiving a request, and framework generating a response. For example, Express or Koa middleware may add CORS headers, logging, compression, and more. The best feature of middleware is that it’s composable in a chain. You can use multiple independent third-party middleware in a single project.

 Redux middleware solves different problems than Express or Koa middleware, but in a conceptually similar way. **It provides a third-party extension point between dispatching an action, and the moment it reaches the reducer.** People use Redux middleware for logging, crash reporting, talking to an asynchronous API, routing, and more.
