We often need to allow our users to perform various delicate operations. They often can’t be undone, which might have dire consequences. Therefore, the good idea is to prompt the user for confirmation. Across our application, the above case might happen frequently. Creating a separate confirmation modal for each of them is far from ideal. […]
We can determine what page the user sees based on the visited URL in a web application with routes. There is more than one way of managing routes with modern single-page applications (SPA). In this article, we look into how hash routing works. We also explain the more modern approach to routing using the history […]
TypeScript is getting more and more popular. Therefore, it is a great time to start using it if you haven’t already. Chances are, our project has been developed for quite some time. If that’s the case, the best approach could be to introduce TypeScript to the codebase gradually. We might encounter a case where we […]
Recently, we’ve developed a GraphQL API in our NestJS series. NestJS under the hood uses Apollo Server. Although it is compatible with any GraphQL client, the Apollo platform also includes the Apollo Client. If you want to know more about GraphQL and how to develop a backend with it, check out API with NestJS #27. […]
Handling forms manually is not difficult in React. Keeping all of the code consistent in your project might be quite a hassle, though. There are many ways in which we can tackle the state of our forms and validation. We can expect the approach of our teammates to differ slightly. To manage our forms better, […]
With React, we have quite a few options when it comes to state management. One of the most obvious ones is using the local state. Unfortunately, it might lead to prop drilling. It happens when we pass data from one component through many layers. When some of the components along the way do not need the […]
One of the qualities of our code that we should aim for is reusability. Also, following the Don’t Repeat Yourself principle makes our code more elegant. In this article, we explore writing functional React components with TypeScript using generic props. By doing so, we can create reusable and flexible components. If you would like to […]
Fetching resources is a bread and butter of the frontend development. When doing so, we might encounter a set of issues related to race conditions. In this article, we identify them and provide a solution. Defining a race condition The term “race condition” dates back to as far as 1954. We use it in the field […]
The hooks are an exciting addition to React and undoubtedly one that helps us to separate the logic from the template. Doing so makes the above logic more testable. Unfortunately, testing hooks does not prove to be that straightforward. In this article, we look into how we can deal with it using react-hooks-testing-library. Identifying the tricky […]
The essential thing when approaching design patterns is to utilize them in a way that improves our codebase. The above means that we sometimes can bend them to fit our needs. The Facade design pattern is commonly associated with object-oriented programming. That doesn’t change the fact that we can take its fundamentals and apply them […]
