Ouch

NodeJS errors for cool kids

---

Ouch is a NodeJS implementation of PHP's Whoops library. It's not an exact port of Whoops, but implements similar functionality and uses same front end resources in some of its error handlers. It is an error handler base/framework for NodeJs. Out-of-the-box, it provides a pretty error interface that helps you debug your web projects, but at heart it's a simple yet powerful stacked error handling system.

Usage examples

    // With PrettyPageHandler
    http.createServer(function nsjfkj(req, res){

        if (req.url === '/favicon.ico') {
            res.writeHead(200, {'Content-Type': 'image/x-icon'} );
            res.end();
            return;
        }

        var d = domain.create();

        d.on('error', function(e){
            var ouchInstance = (new Ouch).pushHandler(
                    new Ouch.handlers.PrettyPageHandler('orange', null, 'sublime')
                );
            ouchInstance.handleException(e, req, res, function (output) {
                console.log('Error handled properly')
            });
        });
        d.run(function(){

            // your application code goes here

        });

    }).listen('1338', 'localhost');


    // With custom callback handler
    var ouchInstance = (new Ouch).pushHandler(
        function(next, exception, request, response){

            // custom handler logic

            next();
        });

    ouchInstance.handleException(e, req, res, function (output) {
        console.log('Error handled properly')
    });
