To understand how to use this technology, I wrote an article called ‘How To Use ReactJS’. You will read about the basic concepts of the library, which will give you an idea of the functionality and use. Let’s start from the beginning.
- Like any development project, it should start with preparation. You can use Facebook’s create-react-app package to create a basic React app. This is probably the most popular approach to setting up a working environment to get started with development. With create-react-app, the programmer gets at his disposal a lot of necessary tools, which eliminates the need to select them on his own. To install create-react-app globally, use the following command: npm i -g create-react-app. Then, to create an app template, run the following command: create-react-app react-intro. This completes the preliminary preparation.
- Now we launch the application and go to the project folder and start the development server, which allows us to open a new React application.
- When working with React, it is important to understand how the structure of your future application works. To do this, open the project you just created with your IDE (I recommend Visual Studio Code). Find the line where your React application will be located. This entire element will be replaced with the application code, and everything else will remain unchanged.
- Now let’s open the src / index.js file that deploys the React application. And by the way, the application source code will be located in the src directory.
- Now you are ready to take a look at the code for your first component. To do this, open the src / App.js file. I n order to make a React component, you must to begin with a class that acquires from React. Component. This can be exactly what the class App extends Component line solves. All React components must contain an usage of the render method, in which, as you might figure from its title, the component is rendered and a description of its visual introduction is formed. This method should return HTML markup for showing it on the page.
So, in order to effectively use React, you need to understand what components are, because as you can see from the development process, they are of incredible importance. Components in React can be made using two approaches. The first one is to use the Class Component, the second is to use the Functional Component. Also, I want to draw your attention to the Single Responsibility Principle (SRP) – this is one of the most important principles of programming that should be followed. It tells us that the module ought to solve only one issue and ought to do it proficiently. In case you create a project without following this rule alone, the code of such a project can turn into a nightmare develop that cannot be supported.
It is worth noting that in this guide I touched upon only the basic concepts of ReactJS and in order to use it fully, you need to study the information in more detail. You might be wondering if I should use React for development? The short answer is yes. Because this technology is suitable for creating many things. Top reasons for use: great for team development, strict adherence to UI, and workflow template; UI code is readable and easy to maintain; component based UI development is the future of web development and you should start doing it now. To be honest, React slows things down initially.
Understanding how props and state work and how components interact is not easy, and documentation is a “maze of information”. In theory, this can be resolved quickly if the whole team is working on it. If your application / website is not full of dynamic pages, you will have to write a lot of code to solve small problems. Despite this, using React in development has a lot of advantages in the process.
We can talk for a very long time about the productive use of React. In particular, how to properly organize the code, and what development techniques are recommended and not recommended to use. While this tutorial is not comprehensive, I believe that if it is your first exposure to ReactJS, then you will be able to effectively master this UI library with what you have learned today. Thanks for reading an article ‘How To Use ReactJS’. Happy coding and hiring from Ava.codes!
