Matcher auto generation

[z4nr34l]

Description: Should generate middleware handler and matcher for exporting in config, where matcher will contain minimal matcher required.

Example:

const {middleware, matcher} = createMiddleware(middlewares, globalMiddlewares);
const config = {
  matcher
};

export { middleware, config }

It's not currently possible as next.js compiler doesn't allow dynamic matchers config.
