Reset middlewares

[Rysakov1986]

Hello! Your package is very cool! But, please add the ability to reset middlewares in nested route.

Example:
path: /api/auth
routes.js // middlewares check jwt token

path: /api/auth/login
reset.js // reset or reset and set new middlewares

Or: add routes.js options for reset or add middlewares.

Thanks!

Indeed, there's a need to avoid applying middleware to all routes inside a folder.

I'm not quite sure if it should be the responsibility of the library, though, at least for now. I'd prefer leaving it to the middleware to decide they do not need to run for a specific route. For example, by wrapping them as such:

// /api/auth/routes.js or maybe /api/routes.js
module.exports = except('/api/auth/login', [checkJWTToken])

/**
 * Creates a middleware that runs the given list of `middlewares` 
 * (or single middleware) unless the request path matches the given `path`
 * @param path String 
 * @param middlewares Function|Array<Function>
 * @return Function
 */
function except(path, middlewares) {
	// Automatically wrap arrays of middlewares
	if (Array.isArray(middlewares)) {
		return middlewares.map(middleware => except(path, middleware))
	}

	return function(req,res,next) {
		// Implementation might be a bit naive here
		// update to suit your own needs
		if (req.path !== path) {
			return middlewares(req,res,next);
		}
		next();
	}
}

function checkJWTToken(req, res, next) {
	// ...
}

Guess there's a slight overhead as the check would happen for each middleware. Not sure if Express or a library provides an API that allows to combine multiple middlewares into one:

module.exports = except(path, group(mw1,mw2,mw3))
