Welcome back! Not surprisingly that every developer wants to create a successful application that will appeal to both the customer and its users. Maybe some even dream to become an expert in developing ReactJS apps. But for this you need to master this library and run into more than one stone. Although it is better to learn from other people’s mistakes than from your own, so I wrote this article on how to avoid mistakes when working with React and create a successful project. Maybe you will see some mistakes and understand that you also make them. Let’s get started!– Advertisement –
Then we can outline three main differences:
1) it has a slightly less abstraction than other libraries; you can use the power of React in more detail and write more efficient applications accordingly;
2) React is a library, not a framework; that is, a library that simply renders some elements; this means that to create a complete application, you can use any set of tools you want and you are not limited; in fact, it also allows a lot of possibilities for very flexible solutions;
3) React is the most popular tool at the moment, it has the most users, that is, there is a huge number of solutions and some snippets on the Internet that you can easily find them and use on your project.
So, after getting acquainted with all the advantages and functions of the ReactJS, it seemed that there should be no problems when working with it. But let’s go back to the most common mistakes and useful tips for a ReactJS developer!
- The first thing we will consider is the File Organization. It’s very important but it’s done very poorly in a lot of cases. Most people use React to create a new application and your folder structure looks not so good. If we started continuing to add components CSS files just into the SRC folder we would end up with a huge mess really quickly. To avoid this, organize the folders like a chain. You will have for example assets folder, images, components, helper folders. And in the RegisterService folder, you can put other files. File and folder structure is very important. There’s no right or wrong way how to do it but it is something definitely important for your project. So if you’re starting a new project, you and your team should decide on some kind of standard that you wanna stick to and of course you have to think how quickly these apps grow and how maintainable your system is going to be. So, in React your file structure will grow rapidly considering every component that has at least one file associated with it.
- Some developers very often forget about optimization. You need to describe absolutely all the conditions for updating your components, try to describe their typing. Because the quality of the code depends on this, as well as how your application will work. Your app will run very slowly if you don’t pay enough attention to it.
- Large spaghetti codes. Starting from the very beginning, you need to create a large base of reused components as possible that will help you optimize, simplify support and test your application. Keep this in mind and try to reuse your code as often as possible. It is one of the best approaches you can think of. But keep in mind that reused components must be polished to perfection, covered with tests, all update conditions are described and things like that.
- Next popular mistake is to forget to use keys when you want to render a list of components. So you must specify which unique parameter will be the key. It is also bad practice to assign the key to the index of a given array. Because you will delete one element, and in all subsequent ones will change the index.
- Use fragments instead of s. Often we have a lot of components, which we have to wrap in a div, because render only allows one component to be returned. Because of this, we add an extra HTML element to the document.
So, now you know cool tips for creating a successful app and how not to do the same mistakes twice. This article has outlined all the intricacies of working with ReactJS and provided a little help for you. Thanks for reading, wish you happy coding!
