# node-express-async

Automatically handles unhandled async middleware errors by sending them to next() function.

This way you don't need and you won't forget to try-catch all middlewares for default 

error handling.

## Usage

You need to *require* the module (only) once by application for example in app.js:

```javascript

require("node-express-async");

```

After this you can use async middlewares normally, like this:

```javascript

const router = express.Router();

router.get('/', async (req, res, /* next */) => {

    // You don't need the try-catch

    // try {

    ... your code

    // } catch(err) {

    //     next(err);

    // }

})

```

## How it works

It modifies Route object of Express, to every middleware which has async prefix 

will be wrapped by asyncMiddleware function. The wrapper creates a Promise, which if 

rejected calls the next function.
