> Compose an array of middleware into a single function for use in Express, Connect, router, etc.

## Installation

```sh

npm install compose-middleware --save

```

## Usage

Compose multiple middleware functions into a single request middleware handler, with support for inline error handling middleware.

```js

var express = require("express");

var compose = require("compose-middleware").compose;

var app = express();

app.use(

  compose([

    function(req, res, next) {},

    function(err, req, res, next) {},

    function(req, res, next) {}

  ])

);

```

**P.S.** The composed function takes three arguments. Express.js (and Connect, router) only accept error handlers of four arguments. If you want to return an error handler from `compose` instead, try the `errors` export - it works exactly the same, but exposes the four argument middleware pattern.
