For example: app.use(function(err, req, res, next) { console.error(err.stack); res.status(500).send('Something broke!'); }); You define error-handling middleware last, after other app.use() and routes calls; for example: var bodyParser = require('body-parser'); var methodOverride = require('method-override'); app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); app.use(methodOverride()); app.use(function(err, req, res, next) { // logic }); Responses from within a error handling in middleware function can be in any format that you prefer, such as an HTML error page, a simple message, or a JSON string. For organizational (and higher-level framework) purposes, you can define several error-handling middleware functions, much like you would with regular middleware functions. For example, if you wanted to define an error-handler for requests made by using XHR, and those without, you might use the following commands: var bodyParser = require('body-parser'); var methodOverride = require('method-override'); app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); app.use(methodOverride()); app.use(logErrors); app.use(clientErrorHandler); app.use(errorHandler); In this example, the generic logErrors might write request and error information to stderr, for example: function logErrors(err, req, res, next) { console.error(err.stack); next(err); } Also in this example, clientErrorHandler is defined as follows; in this case, the error is explicitly passed along to the next one. Notice that when not calling “next” in an error-handling function, you are responsible for writing (and ending) the response. Otherwise those requests will “hang”
