# pr-express-server

ExpressJS based server with useful middlewares

## Philosophy

Simple and ready-to-use express-server pre-loaded with commonly used middleware provided as a starting point for development

## Installation

```bash
$ npm install pr-express-server
```

## APIs

The module exposes a simple create-function and returns an ExpressJS app with pre-loaded middleware. These middleware can be configured via options passed to the function. The app also has updated methods to start/listen and stop/close the server.

```js
var server = require("pr-express-server");

// create server
var app = server(options);

// setup the business-login as would with an express-app
app.set(); // properties
app.use(); // handlers

// start
app.listen(callback);

// stop
app.close(callback);
```
