July 13, 2020 — In this article, Rachel Andrew takes a look at a new effort to crowdfund the costs of implementing browser features. She encourage developers to use, talk about, and raise implementation bugs with browsers to try to get features implemented, however, what if there was a more direct way to do so? What if web developers could get together and fund the development of these features? This article is based on an interview with Brian Kardell, Developer Advocate at Igalia. Read more…

June 17, 2020 — UI or User Interface test is a form of acceptance testing done to verify the user flows of your front-end application. The emphasis of these kinds of software tests is on the end-user that is the actual person who will be interacting with your web application on a variety of devices ranging from desktops, laptops to mobile devices. In this final part of Mirage JS Deep Dive series, Kelvin Omereshone will be putting everything you’ve learned in the past series into learning how to perform UI tests with Mirage JS. Read more…

June 11, 2020 — In this article, Adeneye David Abiodun explains how to build a facial recognition web app with React by using the Face Recognition API, as well as the Face Detection model and Predict API. The app built in this article is similar to the face detection box on a pop-up camera in a mobile phone — it’s able to detect a human face in any image fetched from the Internet. Please note that you will need to know the fundamentals of React. Read more…

June 10, 2020 — So far, we have seen how we can create records with Mirage, intercept API requests via route handlers and, last but not least, how the shape of the data returned to us from Mirage is affected. In this third part of Mirage JS Deep Dive series, Kelvin Omereshone will be focusing on using response, timing and passthrough in Mirage for a better handle on simulating an actual backend server. However, before you begin reading this article, please read the introduction to MirageJS first as well as Part 1 and Part 2 of this series. Read more…

June 9, 2020 — To make the move from “site” to app, we’ll need to dive into the world of “app-generated” content. In this article, Bryan Robinson will get you started in this world with the power of serverless data. He’ll start with a simple demo by ingesting and posting data to FaunaDB and then extend that functionality in a full-fledged application using Auth0, FaunaDB’s Token system and User-Defined Functions.

June 3, 2020 — If you’re a React developer who’d like to learn how you can start consuming APIs in your React applications, then this article is for you. Consuming REST APIs in a React Application can be done in various ways, but in this tutorial, Shedrack Akintayo will be discussing how we can consume REST APIs using two of the most popular methods known as Axios and Fetch API. You will learn what a REST API is and how to build a simple application that consumes a REST API by using both Fetch API and Axios. Read more…

May 29, 2020 — Factories are a faster way to create new database records., A fixture is a state of a set or collection of objects that serve as a baseline for running tests, and a serializer is responsible for transforming the response. In this second part of the Mirage JS Deep Dive series, Kelvin Omereshone will be looking at Mirage JS’ Factories, Fixtures, and Serializers. You’ll see how they enable rapid API mocking using Mirage. Read more…

April 30, 2020 — Mirage JS borrowed some terms and concepts which are very much familiar to back-end developers, however, since the library would be used mostly by front-end teams, it’s appropriate to learn what these terms and concepts are. In this first part of the Mirage JS Deep Dive series, Kelvin Omereshone will be looking at Mirage JS models and associations. He’ll take a closer look at what they are and the roles they play in crafting out production-ready frontend without an actual backend with Mirage JS. Read more…
