If you’ve been building anything with Node.js for long enough, then you’ve no doubt experienced the pain of unexpected speed issues. JavaScript is an evented, asynchronous language. That can make reasoning about performance tricky, as will become apparent. The surging popularity of Node.js has exposed the need for tooling, techniques and thinking suited to the constraints of server-side JavaScript. When it comes to performance, what works in the browser doesn’t necessarily suit Node.js. So, how do we make sure a Node.js implementation is fast and fit for purpose? Let’s walk through a hands-on example. Tools Node is a very versatile platform, but one of the predominant applications is creating networked processes. We’re going to focus on profiling the most common of these: HTTP...

Ever wanted to do specific things on your application server at certain times without having to physically run them yourself. You want to spend more of your time worrying about productive tasks instead of remembering that you want to move data from one part of the server to another every month. This is where Cron jobs come in. In your Node applications, the applications of these are endless as they save. In this article, we’ll look at how to create and use Cron jobs in Node applications. To do this, we’ll make a simple application that automatically deletes auto-generated error.log files from the server. Another advantage of Cron jobs is that you can schedule the execution of different scripts at different intervals from your application. Prerequisites To follow through th...
