An Introduction To CSS Cascade Layers

CSS recently turned 25 years old, and over that time, many techniques and tools have been created to help developers work with the cascade. Within the last year, a new spec to orchestrate the “C” in CSS was drafted and is now an official candidate recommendation: cascade layers. Cascade layers allow controlling the specificity and order of rule sets across stylesheets. We all have run into CSS collisions and sudden regressions in our codebases when new styles are written or 3rd-party styles are added. This is because of the interdependence of styles due to source order, specificity, and inheritance. Some ways to control the cascade have included methodologies like ITCSS and BEM and other newer native features like CSS custom properties and :where/:is. Cascade layers will be the ultimate na...

Getting Started With the File System Access API

The File System Access API is a web API that allows read and write access to a user’s local files. It unlocks new capabilities to build powerful web applications, such as text editors or IDEs, image editing tools, improved import/export, all in the frontend. Let’s look into how to get started using this API. Reading files with the File System Access API Before diving into the code required to read a file from the user’s system, an important detail to keep in mind is that calling the File System Access API needs to be done by a user gesture, in a secure context. In the following example, we’ll use a click event. Reading from a single file Reading data from a file can be done in less than 10 lines of code. Here’s an example code sample: let fileHandle; document.querySelector(".pick-file"...

GraphQL On The Front-End (React And Apollo)

One of the main benefits of GraphQL is the client’s ability to request what they need from the server and receive that data exactly and predictably. Without much effort, one can easily pull nested data by just adding more properties to our queries instead of adding multiple endpoints. This prevents issues like over-fetching that can impact performance. Usually, to handle GraphQL on the client-side, we make use of the Apollo Client. It allows developers to define, handle, and make queries/mutations available within our application. It can also act as a state management tool with your client-side application. In this article, we’re going to learn how to handle real-time updates on the client-side using GraphQL. We’ll be learning how to do this with GraphQL Features like Cache Update, Subsc...

React Children And Iteration Methods

The most obvious and common prop that developers work with within React is the children prop. In the majority of cases, there is no need to understand how the children prop looks like. But in some cases, we want to inspect the children prop to maybe wrap each child in another element/component or to reorder or slice them. In those cases inspecting how the children prop looks like becomes essential. In this article, we’ll look at a React utility React.Children.toArray which lets us prepare the children prop for inspection and iteration, some of its shortcomings and how to overcome them — through a small open-source package, to keep our React code function the way it is deterministically supposed to behave, keeping performance intact. If you know the basics of React and have at least an ide...

Making GraphQL Work In WordPress

Headless WordPress seems to be in vogue lately, with many new developments taking place in just the last few weeks. One of the reasons for the explosion in activity is the release of version 1.0 of WPGraphQL, a GraphQL server for WordPress. WPGraphQL provides a GraphQL API: a way to fetch data from, and post data to, a WordPress website. It enables us to decouple the experience of managing our content, which is done via WordPress, from rendering the website, for which we can use the library of the framework of our choice (React, Vue.js, Gatsby, Next.js, or any other). Until recently, WPGraphQL was the only GraphQL server for WordPress. But now another such plugin is available: GraphQL API for WordPress, authored by me. These two plugins serve the same purpose: to provide a GraphQL API...

Reactivity In Vue

In this article, we’re going to look at reactivity in Vue, how it works, and how we can create reactive variables using newly created methods and functions. This article is targeted at developers who have a good understanding of how Vue 2.x works and are looking to get familiar with the new Vue 3. We’re going to build a simple application to better understand this topic. The code for this app can be found on GitHub. By default, JavaScript isn’t reactive. This means that if we create the variable boy and reference it in part A of our application, then proceed to modify boy in part B, part A will not update with the new value of boy. let framework = 'Vue'; let sentence = `${framework} is awesome`; console.log(sentence) // logs "Vue is awesome" framework = 'React'; console.log(sentence) //...

Search Engine Optimization Checklist (PDF)

Search engine optimization (SEO) is an essential part of a website’s design, and one all too often overlooked.

Reactive Variables In GraphQL Apollo Client

In this article, we will look at how to set up reactive variables, how the GraphQL cache polices come into place in defining read and writes to the cache, and provide the ability for developers to add types that exist on the client-side alone so that we can structure queries for client-side variables same way we can for remote GraphQL data. After learning more about the fundamentals of reactive variables, we will build a simple app that switches the theme of our application to either dark mode or light mode based on the value of our reactive variable. We will be looking at how to query a reactive variable, how to update the value stored in a reactive variable, and how the change in value triggers updates in components that depend on the reactive variable for certain actions to occur. The ...

Getting Started With Next.js

Lately, Next.js has termed itself The React Framework for Production, and with such bold claim comes a bevy of features that it offers to help you take your React websites from zero to production. These features would matter less if Next.js isn’t relatively easy to learn, and while the numerous features might mean more things and nuances to learn, its attempt at simplicity, power, and perhaps success at it is definitely something to have in your arsenal. As you settle in to learn about Next.js, there are some things you might already be familiar with and you might even be surprised at how it gives you a lot to work with that it might seem almost overwhelming at face value. Next.js is lit for static sites and it has been well-engineered for that purpose. But it also takes it further with i...

Authentication In Vue.js

Authentication is a very necessary feature for applications that store user data. It’s a process of verifying the identity of users, ensuring that unauthorized users cannot access private data — data belonging to other users. This leads to having restricted routes that can only be accessed by authenticated users. These authenticated users are verified by using their login details (i.e. username/email and password) and assigning them with a token to be used in order to access an application’s protected resources. In this article, you’re going to be learning about: Vuex Configuration with Axios Defining Routes Handling Users Handling Expired Token Dependencies We will be working with the following dependencies that help in authentication: AxiosFor sending and retrieving data from our API ...
