Ouch!

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.

Installation

The source is available for download from GitHub. Alternatively, you can install using Node Package Manager (npm):

npm install ouch

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
var ouchInstance = (new Ouch).pushHandler(
    function(next, exception, inspector, run, request, response){

        // custom handler logic

        next();
    });

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

For more options, have a look at the example files in examples to get a feel for how things work. Also take a look at the API Documentation and the list of available handlers below.

Available Handlers

Ouch currently ships with the following built-in handlers, available in the

require("ouch").handlers
namespace:
  • PrettyPageHandler
    - Shows a pretty error page when something goes pants-up
  • JsonResponseHandler
    - Process errors and returns information on them as a JSON string.
  • CallbackHandler
    - Wraps a callable as a handler. You do not need to use this handler explicitly, Ouch will automatically wrap any callable you pass to
    ouchInstance.pushHandler
    .

Todo

- Add more handlers.
