requestDefaultsMiddleware

Middleware to set defaults on `requestInit`.

This is a convenience for other middleware so they can assume certain properties
are always set.

* If `method` is not set it will set it to `GET`
* If `headers` is not set will set it to `new Headers()`

This is included by default in [Endpoint.defaultConfig.getMiddleware](doc:Endpoint#static-var-defaultConfig).

__namedParameters

Allows definition of URL as a pattern with ability to resolve it to a URL by performing argument replacement

Patterns are defined using the [path-to-regexp](https://github.com/pillarjs/path-to-regexp) library

Usage:

```js
const url = new UrlPattern('/users/:id/'),
url.resolve({ id: 5 });
// /users/5/
url.resolve({ id: 5 }, { query: { showAddresses: true }});
// /users/5/?showAddresses=true
```

__index

Query

Same as [fetch](https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch#Parameters) but
guarantees `headers` is set and is a `Headers` instance, and `method` is set.

RequestInit

MiddlewareNextReturn

Only available in the response part of the middleware.


decodedBody

response

Response

The final value to return from middleware. This starts as `decodedBody` but can be modified
by middleware as it passes through them.
