To complete this tutorial, you will need: 1. For instance, we can have a button component display with different colors in several parts of our application. These third-party components tend to be reusable. React is more powerful the tinier each component is - it makes the overall application easier to navigate and encourages as many components as possible to be stateless. One piece is missing though. Hey quick accessibility heads-up. Use TypeScript — avoid prop-types. Great article, thank you. React Function Components -- also known as React Functional Components -- are the status quo of writing modern React applications. Components are the building blocks of React applications. Now let’s say you’re working on a login form. Wanna give this a try yourself? In React, a component's API is its props. The key idea is to make it generic. Thus, we wrapped our reusable Form Group component in the React memo function to prevent it from re-rendering if the props had not changed. Every time we specify this property from the outside, we override the default prop given in the Button component (here: Button Two). We can do same thing with inputs, location Inputs, file uploader componets or anything which is used more then 1 place in our codebase. With React, you create components. into reusable components with well-defined interfaces. What about reusing components because they serve a more common purpose? If you’ve been building applications that accept user input via forms, you might have come across the need to make some form fields dynamic. Unfortunately you don’t set the id on the input field. You have seen how to refactor a React component from being specific to being more generic. Let's start by creating a simple form button component which is a touchable element that allows the user to interact with the device’s screen and perform the next action. We all know that React components let you divide your UI into sharable design elements (button, form, form-field, table, spinner etc). We'll also cover the best practices because even experienced developers get it wrong. This makes for a good component because it enforces good markup (something Brad Frost calls dumb React) which goes to show that not every component has to be some highly complex piece of functionality. Let's experience this by refactoring a component from being very specific to being more generic. No setup configuration. Usually when we start off with our React application, we don't have any components except for our root component commonly called App: For instance, in order to make this HTML button reusable in React, we have to extract it to its own component. I avoided JavaScript from the beginning of my career as a programmer, and I think it was mostly because I didn't have a good way of keeping and maintaining a state in components. When you encapsulate the , you are in effect creating a new API for the developer, so the developer has to look up the API before creating a new . Hi Silas, We can combine the two by making the React state be the “single source of truth”. 1. These third-party components tend to be reusable. How to make a React component reusable? Generally speaking we make a component more reusable by turning it from specific to more generic. The idea is to ensure that the component can be used in as many scenarios as possible. Reading Time: 4 minutes If you want to learn how to create a reusable table component with react js and bootstrap to display data in a beautiful tabular format in your application with less code and higher reusability within just 10 mins then please read through this post and you will be a PRO in creating reusable table component in ReactJS. So I might opt for having a name prop to determine the type of icon to display. We’re using it both as the text input for a username and another text input for a password. Would you add that logic in the FormInput component and then enable it via “addPasswordReveal” prop or rather create a new separate component “FormInputPassword”? With React Native, you use JavaScript to access your platform’s APIs as well as to describe the appearance and behavior of your UI using React components: bundles of reusable, nestable code. I've used WordPress since day one all the way up to v17, If we want to make any changes to how the input functions, we can make those changes inside the FormInput component file we created and they will be applied to every instance where the input component is used. The type attribute of our button is wired in the Button component and we cannot do anything about it from the outside. That way, the next time you need to build some UI, you can write much less code. You can have the buyer choose the design they want. Step 1. Contribute to gkhan205/react-reusable-form-component development by creating an account on GitHub. Personal Development as a Software Engineer. The possible yardstick for making something a reusable component probably ought to be when you need the same functionality in other parts of an application. You can see that we’re not making assumptions by predefining anything. Recently, I've been spending a majority of my time in React and I began to really enjoy front-end JavaScript development. It’s almost impossible to build a React application and not make use of components. Coyier and a team of swell people. Let's define a Button component for it: Using this Button component as element in React's JSX creates every time a new instance of this Button component. CodePen is a place to experiment, debug, and show off your HTML, CSS, and ... React basic 3 — Reusable Functional Components.

Generic React components are commonly widely used in the entire application because they are highly reusable. I’ll like to see what you came up with, so link up your work in the comment section! Another property could be the label showing up for the button: We can also use React's built-in children property which is commonly used for composition in React: The Button component is almost a 100% generic by offering an API to the outside. React basic 6 — Use Axios Library to Fetch Data. for local development. It’s widespread to the point that some third-party packages provide you with components you can use to integrate functionality into your application. Thanks for the article, it’s very well written. Thus you can’t click the label to focus the input. *May or may not contain any actual "CSS" The simplest way to define a component is to write a JavaScript function:This function is a valid React component because it accepts a single “props” (which stands for properties) object argument with data and returns a React element. It’s almost impossible to build a React application and not make use of components. Here’s our final login form when all of our components are put together. business, with a local development tool to match. Try working on a reusable ,
