Better error pages for Node.js. A collection of middleware for better error handling and reporting with Express 3/4 and Koa. Also compatible with other connect-style frameworks.

Overview

The library exposes middleware specific to both Express as well as Koa.

Express middleware:

• oops.wrapRequests: Binds all request/response pairs to domains. This localizes any uncaught exceptions thrown during a request life-cycle to the given request.
• oops.express: Installs an error handler and error page

Koa middleware:

• oops.koa: Installs an error handler and error page

It also exposes a function for installing an error dashboard:

• oops.installDashboard: Install the oops dashboard in an express or koa app

Express 3.x and 4.x

Basic development setup:

var oops = require('oops.js');

if (app.settings.env === 'development') {
  app.use(oops.express());
}

Using a redis client to track errors among multiple node instances, as well as wrapRequests and the dashboard.

var redis  = require('redis');
var client = redis.createClient();
var oops = require('oops.js');

app.use(oops.wrapRequests);
if (app.settings.env === 'development') {
  app.use(oops.express());
  oops.installDashboard(app, {redis: client});
}
