The combination of Next.JS and Styled Components is truly epic. You get fast, Static Rendered, highly semantic code as a result of the union, but you also get an error unless you know the secret config that solves it (like so many things in our industry…. 😒).
This is likely the error you’re getting, or some variant of it:
Warning: Prop `className` did not match. Server: "sc-gKsewC" Client: "sc-dlfnbm"For some reason, it’s actually kinda hard to find the solution. It’s listed on an obscure Github issue somewhere. Well, without further ado, here you go.
First run:
npm i babel-plugin-styled-components…

It is of utmost importance that we make our code as readable and semantic as possible, so that the next person who comes and reads it is able to quickly understand what the intention was, what the logic is, and how to alter it to meet the new business requirements.
Inline Styles
It is generally accepted that inline styles are not the best idea, because they make the code so much less readable.
Imagine if we were on a page that contained…

Security has to be a core part of our work, not an auxiliary skill. As such, it helps to know the most common types of attacks that hackers carry out.
Common Pathways of Attack
The following access points into your application allow a User to provide custom input. A hacker can take advantage of these access points to send malicious code instead of valid data, which can cause unwanted and dangerous effects, and compromise security.

Using Formik together with Yup, TypeScript, and react-select can seem a little daunting at first. I mean, getting different libraries that share concerns to play nice together is often a recipe for hours of Googling how someone else did it, then finding that the implementation doesn’t work on…

Often, the hardest part of using a package is configuring it and making sure it plays nice with all the other packages that work in the same domain.
Naturally, there’s significant overlap between ESLint, Prettier, and TypeScript, and if you haven’t set it up in the right way, you’ll soon be gazing in a bovine trance at the “Great Wall of Errors”.
In this article, we’ll go over installation and configuration, but we’re not going to…

This one really took me a while. I got all the concepts, but there were several coffee (pfft… and cookie) breaks until I figured out exactly what the directory mappings needed to be.
tl;dr
Implementing Hot Reloading with Docker and Next.JS is literally two (2) lines of code! npm run dev, and a mapping between your local project directory and a directory on your Docker instance, using a volume:
./:/srcThat’s it! (although I use usr/src/app instead…

In the previous article, we explored how to get started with Docker, but the app we built was incredibly simple. All it did was respond with a string to a HTTP request to the main URL.
What if we wanted to do something a little more complex? How about a React app that stores its state in MongoDB?
App Explanation
You can see the code for the app here:

So this is a really simple CRUD app…

This article continues our discussion of React’s Additional Hooks. The official documentation on how to use these hooks is pretty sparse, so I feel that there’s a need to make a blog post about them. Let’s dive in and get hooked on hooks! (yeah, I know, that was pretty bad… 😂)
useRef
The traditional use of useRef is to store a reference to a DOM node. If the DOM node updates, so does the reference. …
