# router-fns : absolutely simple routing libary

Absolutely simple, so that strong. All you need is handler, as with linux's process. It's just that.

## Installation

```

$ npm i -SE router-fns

```

## Usage

### Handler

Express-like handler.

```ts

const handler = (req, res, next) => {

  try {

    // do something

    next();

  } catch (e) {

    next(e);

  }

};

```

### reduceHandlers

Reduce multiple handlers into one handler.

This reducer is designed to implement middleware pattern.

```ts

import { reduceHandlers } from 'router-fns';

const handler = reduceHandlers(handlerA, handlerB, handlerC);

```

### initHandler

A handler which initializes request object for routing. It is required to be called before routing.

```ts

import { reduceHandlers, initHandler } from 'router-fns';

const rootHandler = reduceHandlers(initHandler, router);

```

### routingHandler

Create a handler which aims to route recieved request to appropriate handler.

```ts

import { routingHandler, initHandler } from 'router-fns';

const router = routingHandler({

  '/routeA': routingHandler({

    '/subRouteA': handlerA

  }),

  '/routeB': handlerB

});

const rootHandler = reduceHandlers(initHandler, router);

rootHandler({ url: '/routeA/subRouteA' }, {}, e => {

  if (e) throw e;

});

```
