Node.js framework agnostic HTTP error handler.
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)const { restana: errorHandler } = require('agnostic-http-error-handler')()
const service = require('restana')({
errorHandler
})
service.get('/throw', (req, res) => {
throw new Error('Upps!')
})
service.start()const { native: errorHandler } = require('agnostic-http-error-handler')()
...
server.on('request', (req, res) => {
try {
// request handler logic...
} catch (err) {
errorHandler(err, req, res)
}
})In case you would like to extend the error processing logic of your application, you can use the preErrorHandler configuration callback:
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
preErrorHandlerinvocation response can be coerce as a TRUE value, sending theresponsePayloadto the client is aborted.
