A long time ago when I had been exploring session management in Node.js, I had written a tutorial titled, Session Management in Your Express.js Web Application. This was a basic tutorial that is still very functional today, however little things have changed since then when it comes to how the web works. For example, in 2015 HTTPS was never a requirement and we weren’t exposed to all the frontend web frameworks that exist today.
When you start introducing things into your web applications such as HTTPS or micro-services that operate on different origins or ports, or frontend frameworks, session management can get a little more complicated. We’re going to see how to maintain a session for a user using Node.js with Express.js on our backend and Vue.js on our frontend, in this tutorial.Read More
About a week ago I had written about using HTTPS with Node.js and hinted at hardware based two-factor authentication as my reason for needing it. In case you’re unfamiliar with 2FA, there are numerous approaches ranging from HMAC-based one-time passwords (HOTP) and time-based one-time passwords (TOTP) which are software based, to the hardware based universal two-factor (U2F) standard.
If you’ve been keeping up with the blog, you’ll remember I had written a tutorial titled, Implement 2FA with Time-Based One-Time Passwords in a Node.js API, which focused on the software side of things. I recently picked up some YubiKey dongles and thought I’d try my luck with the hardware side of things.
In this tutorial, we’re going to see how to implement U2F functionality in our Node.js powered RESTful API and interact with the API and our hardware dongles using jQuery in the web browser.Read More
I recently picked up a Yubico U2F hardware key and thought I’d try to create a web application that was protected with two-factor hardware-based authentication. Things were going smooth until I realized that it is mandatory to be using HTTPS within your application, even when testing locally. HTTPS is common, but I’d never actually set it up with Node.js because I had always been using services like Cloudflare that configure it for you. The problem is that these services are for live domain names, not necessarily localhost.
While we’re not going to explore U2F hardware keys in this tutorial, we’re going to take a look at creating and installing a self-signed certificate for use in Node.js within macOS.Read More
The book was designed to help make you successful at modeling and validating your data, designing queries, and anything related to creating web services.Read More
Most modern web applications need to be able to handle data consumption requests and data manipulation requests from clients using HTTP. It is the norm to pass JSON data between these requests so it makes sense to use a NoSQL document database because JSON and similar is the common storage format, eliminating the need to marshal data to new formats in every request.
Lucky for us, leveraging these concepts and technologies is not a difficult task.Read More
We’re going to see how to take a CSV file, parse it into JSON, make some changes, and then convert it back into a CSV file using Node.js and a few readily available packages.Read More
