Does your site still send password reminders via email? This should be a red flag to you, as both a user of the website and as a developer. Either your password is stored in plain text or it can be decrypted, instead of having the much stronger, more secure one-way encryption. In this article, Jamie Munro will demonstrate how to use JSON Web Tokens (JWT) to generate a URL-safe token. The JWT contains encoded information about the user and a signature that, when decoded, is validated to ensure that the token has not been tampered with. Jamie will focus on the password-reset process by securing the password-reset flow with a URL-safe token that is validated with a signature.

In this article, Owais Afaq gives you hands-on access to his journey of creating a digital assistant capable of connecting with any system via a RESTful API to perform various tasks. He will create a chatbot using Node.js and Microsoft’s Bot Framework SDK; send the data collected from the user to an API; set up both local and server environments; and deploy it live on dev.botframework.com. In part 2 of this series, you’ll learn how to add natural language processing using LUIS to make our chatbot intelligent enough to understand human language and to extract information from a user’s utterances.

These days, understanding cyber-security is not a luxury but rather a necessity for web developers, especially for developers who build consumer-facing applications. In this article, Hagay Lupesko will show you 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.

Imagine an archaic, alien workflow, with ancient tooling, and none of those things you love about the web. How would your career be affected? As a web developer, not only do you already possess all of the skills to make great modern desktop apps, but thanks to powerful new APIs at your disposal, the desktop is actually where your skills can be leveraged the most. In this article, Adam Lynch will look at the development of desktop applications using NW.js and Electron, the ups and downs of building one and living with one, using one code base for the desktop and the web, and more.

Node.js has helped to bring uniformity to software development. Writing command line tools has also become easier than ever before because of Node.js. Tools such as Yeoman ask for runtime inputs that eventually help you to customize a project’s configuration as well. Some generators in Yeoman help you to deploy a project in your production environment. That is exactly what you are going to learn today. In this tutorial, Nihar Sawant will develop a command line application that accepts a CSV file of customer information, and using the SendGrid API, he will send emails to them.

One of the most famous chat bots was Alice (artificial linguistic Internet computer entity), released in 1995. It wasn’t able to pass the Turing test, but it won the Loebner Prize three times. In 2014, Slackbot made chat bots popular again. In 2015, Telegram and then Facebook Messenger released chat bot support; then, in 2016 Skype did the same, and Apple and some other companies announced even more chat bot platforms. Depending on your idea, target market and the platforms you are most familiar with, you can start with any of the other platforms that support chat bots.

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, Jeremy Wagner will get hands-on with Brotli by writing a Node.js-powered HTTP server that implements this new algorithm, and will compare its performance to gzip.

In this article, Filip Bartos will share his notes about installing and configuring a critical-path performance optimization using Express and Handlebars for an isomorphic React website. This website was developed using React, running on an Express server, and it was going well, but Filip still wasn’t satisfied with a load-blocking CSS bundle. So, he started to think about options for how to implement the critical-path technique on an Express server. Throughout this article, Filip will be using Node.js and Express. Familiarity with them will help you understand the examples.

In this article, Adam Simpson will cover Grunt, Gulp, Webpack and npm scripts, providing some examples of each one to get you started into task runners. Task runners can solve real problems. Adam has used them to compile different builds of a JavaScript application, depending on whether the target was production or local development, or to compile Handlebars templates. Task runners are constantly evolving and changing, and in this article Adam will try to cover the most used ones in the current zeitgeist. Happy task running!

Your “virtual retrospective board” needs to allow team members to sync the current state of the board in real time between all team members, talk about the board via video chat, create, edit and move sticky notes and make sure users log in with the right password. To achieve this you need deepstream and a bit of JQuery. In this article, Wolfram Hampel will show you the step by step you need to know.
