Node.js framework agnostic HTTP error handler.

Usage

$3

``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)
`

$3


`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()

`

$3


`js
const { native: errorHandler } = require('agnostic-http-error-handler')()
...
server.on('request', (req, res) => {
try {
// request handler logic...
} catch (err) {
errorHandler(err, req, res)
}
})
`

$3

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.
