# agnostic-http-error-handler

Node.js framework agnostic HTTP error handler.

## Usage 

### Express.js

```js

const { express: errMiddleware } = require('agnostic-http-error-handler')()

const service = require('express')()

service.get('/throw', (req, res) => {

  throw new Error('Upps!')

})

service.use(errMiddleware)

service.listen(3000)

```

### Restana

```js

const { restana: errorHandler } = require('agnostic-http-error-handler')()

const service = require('restana')({

  errorHandler

})

service.get('/throw', (req, res) => {

  throw new Error('Upps!')

})

service.start()

```

### Native

```js

const { native: errorHandler } = require('agnostic-http-error-handler')()

...

server.on('request', (req, res) => {

  try {

    // request handler logic...

  } catch (err) {

    errorHandler(err, req, res)

  }

})

```

### Pre-Error-Handler callback

In case you would like to extend the error processing logic of your application, you can use the `preErrorHandler` configuration callback:

```js

const logger = require('...')

const { native: errorHandler } = require('agnostic-http-error-handler')((err, responsePayload, req, res) => {

  logger.error(`Unexpected error while processing "${req.method} ${req.url}" request`, err)

})

...

server.on('request', (req, res) => {

  try {

    // request handler logic...

  } catch (err) {

    errorHandler(err, req, res)

  }

})

```

> NOTE: In case the `preErrorHandler` invocation response can be coerce as a TRUE value, sending the `responsePayload` to the client is aborted.
