-All parameter coercions *except* `:body`:
-
-1. Allow keys outside the schema (by opening up the schema using eg. `malli.util/open-schema`)
-2. Keywordize the keys (ie. header & query parameter names) of the input before coercing

-In contrast, the `:body` coercion:

-To select the response content-type, you can either:
-1. Let muuntaja pick the content-type based on things like the request Accept header
-   - This is what most users want
-2. Set `:muuntaja/content-type` in the response to pick an explicit content type
-3. Set the `"Content-Type"` header in the response
-   - This disables muuntaja, so you need to encode your response body in some other way!
-   - This is not compatible with response schema checking, since coercion won't know what to do with the already-encoded response body.
-4. Use the `:extract-response-format` option to inject your own logic. See `reitit.coercion/extract-response-format-default` for the default.

 Ring [defines middleware](https://github.com/ring-clojure/ring/wiki/Concepts#middleware) as a function of type `handler & args => request => response`. It is relatively easy to understand and allows for good performance. A downside is that the middleware chain is just a opaque function, making things like debugging and composition hard. It is too easy to apply the middlewares in wrong order.

 Exceptions thrown in router creation can be [handled with custom exception handler](../basics/error_messages.md). By default, exceptions thrown at runtime from a handler or a middleware are not caught by the `reitit.ring/ring-handler`. A good practice is to have a top-level exception handler to log and format errors for clients.

 ## When to use the registry?
 
 Middleware as Keywords helps to keep the routes (all but handlers) as literal data (i.e. data that evaluates to itself), enabling the routes to be persisted in external formats like EDN-files and databases. Duct is a good example, where the [middleware can be referenced from EDN-files](https://github.com/duct-framework/duct/wiki/Configuration). It should be easy to make Duct configuration a Middleware Registry in `reitit-ring`.

-
-- If you have middleware that you want to apply to the default handler (second argument of `ring/ring-handler`), use _top-level middleware_
-- If you have a generic middleware, that doesn't depend on the route, use _top-level middleware_ or _top-level route data_
-  - If you are using top-level route data anyway for some other reasons, it might be clearest to have all the middleware there. This is what most of the reitit examples do.
-- If you want to apply a middleware to only a couple of routes, use _nested middleware_ (ie. _route data_)
-- If you want a middleware to apply to all routes, but use route-specific data, you need _top-level route data_ combined with [Compiling Middleware](compiling_middleware.md)
