Using Slack To Monitor Your App

For the past few months, I’ve been building a software-as-a-service (SaaS) application, and throughout the development process I’ve realized what a powerful tool Slack (or team chat in general) can be to monitor user and application behavior.

After a bit of integration, it’s provided a real-time view into our application that previously didn’t exist, and it’s been so invaluable that I couldn’t help but write up this show-and-tell.

How To Secure Your Web App With HTTP Headers

Web applications, be they thin websites or thick single-page apps, are notorious targets for cyber-attacks. In 2016, approximately 40% of data breaches originated from attacks on web apps — the leading attack pattern. Indeed, these days, understanding cyber-security is not a luxury but rather a necessity for web developers, especially for developers who build consumer-facing applications.

How To Secure Your Web App With HTTP Headers

HTTP response headers can be leveraged to tighten up the security of web apps, typically just by adding a few lines of code. In this article, we’ll show how web developers can use HTTP headers to build secure apps. While the code examples are for Node.js, setting HTTP response headers is supported across all major server-side-rendering platforms and is typically simple to set up.

Beyond The Browser: From Web Apps To Desktop Apps

I started out as a web developer, and that's now one part of what I do as a full-stack developer, but never had I imagined I'd create things for the desktop. I love the web. I love how altruistic our community is, how it embraces open-source, testing and pushing the envelope.

Beyond The Browser: From Web Apps To Desktop Apps

I love discovering beautiful websites and powerful apps. When I was first tasked with creating a desktop app, I was apprehensive and intimidated. It seemed like it would be difficult, or at least… different.

How To Develop An Interactive Command Line Application Using Node.js

Over the last five years, Node.js has helped to bring uniformity to software development. You can do anything in Node.js, whether it be front-end development, server-side scripting, cross-platform desktop applications, cross-platform mobile applications, Internet of Things, you name it. Writing command line tools has also become easier than ever before because of Node.js — not just any command line tools, but tools that are interactive, useful and less time-consuming to develop.

How To Develop An Interactive Command Line Application Using Node.js

If you are a front-end developer, then you must have heard of or worked on Gulp, Angular CLI, Cordova, Yeoman and others. Have you ever wondered how they work?

How To Develop A Chat Bot With Node.js

In the past few months, chat bots have become very popular, thanks to Slack, Telegram and Facebook Messenger. But the chat bot idea is not new at all.

How To Develop A Chat Bot With Node.js

A chat bot interface is mentioned in the famous Turing test in 1950. Then there was Eliza in 1966, a simulation of a Rogerian psychotherapist and an early example of primitive natural language processing. After that came Parry in 1972, a simulation of a person with paranoid schizophrenia (and, yes, of course, Parry met Eliza).

Next Generation Server Compression With Brotli

Chances are pretty good that you’ve worked with, or at least understand the concept of, server compression. By compressing website assets on the server prior to transferring them to the browser, we’ve been able to achieve substantial performance gains.

Next Generation Server Compression With Brotli

For quite some time, the venerable gzip algorithm has been the go-to solution for reducing the size of page assets. A new kid on the block has been gaining support in modern browsers, and its name is Brotli. In this article, you’ll get hands-on with Brotli by writing a Node.js-powered HTTP server that implements this new algorithm, and we’ll compare its performance to gzip.

Optimizing Critical-Path Performance With Express Server And Handlebars

Recently, I’ve been working on an isomorphic React website. This website was developed using React, running on an Express server. Everything was going well, but I still wasn’t satisfied with a load-blocking CSS bundle. So, I started to think about options for how to implement the critical-path technique on an Express server.

This article contains my notes about installing and configuring a critical-path performance optimization using Express and Handlebars. Throughout this article, I’ll be using Node.js and Express. Familiarity with them will help you understand the examples.

How To Harness The Machines: Being Productive With Task Runners

Task runners are the heroes (or villains, depending on your point of view) that quietly toil behind most web and mobile applications. Task runners provide value through the automation of numerous development tasks such as concatenating files, spinning up development servers and compiling code.

How To Harness The Machines: Being Productive With Task Runners

In this article, we’ll cover Grunt, Gulp, Webpack and npm scripts. We’ll also provide some examples of each one to get you started. Near the end, I’ll throw out some easy wins and tips for integrating ideas from this post into your application.
