How to Build Dynamic Form with Validation in React Hook Form

This is a quick example of how to build a dynamic form with validation in React with the React Hook Form library.

React Hook Form is a relatively new library for working with forms in React using React Hooks, I just stumbled across it recently and will be using it for my React projects going forward, I think it’s easier to use than the other options available and requires less code. For more info see https://react-hook-form.com.

The example form allows selecting the number of tickets to purchase and then entering the name and email of the person each ticket is for, both fields are required and the email field must contain a valid email address. The “Buy Tickets” button simply displays the form values in an alert popup if the form is valid, and the “Reset” button resets the form back to it’s initial state including the removal of all ticket name & email fields.

Styling of the example is all done with Bootstrap 4.5 CSS, for more info see https://getbootstrap.com/docs/4.5/getting-started/introduction/.

App Component with Dynamic React Hook Form

The example app component contains all the code for the dynamic form built with React Hook Form.

Form validation rules are defined with the Yup schema validation library and passed to the useForm() function of the React Hook Form library.

The useForm() hook function returns an object with methods for working with a form including registering inputs, handling form submit, resetting the form, displaying errors, watching for value changes and more, for a complete list see https://react-hook-form.com/api#useForm.

A watcher is created on the numberOfTickets select field to provide access to the current number of tickets and to trigger a for re-render when the number of tickets is changed. The ticketNumbers() function returns an array of ticket indexes (e.g. [0,1,2,3...]) based on the number of tickets selected and is used in the component template to render the dynamic form fields for each ticket.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Validating React Forms With React-Hook-Form

Validating inputs is very often required. For example, when you want to make sure two passwords inputs are the same, an email input should in fact be an email or that the input is not too long. This is can be easily done using React Hook From. In this article, I will show you how.

Required Fields

The most simple, yet very common, validation is to make sure that an input component contains input from the user. React Hook Form basic concept is to register input tags to the form by passing register() to the tag’s ref attribute. As we can see here:

Build a Contact Form with React Hooks and PHP

A while ago I wrote an article about creating a contact form using React and PHP. Many people found it interesting. So, here I am writing an updated version of that article.

Check out the article about creating a contact form with React and PHP:

Hooks are a new addition in React and we are going to re-create the contact form using React Hooks.

Prerequisites? Not really!

Same as the previous project. This tutorial is beginners friendly. You don’t have to be an expert in Javascript, React, or PHP but I won’t go into basic details like installing React and setting up the project.

I assume you already have an up and running React project. We will focus on creating the component.

Creating the component

If you have a component folder in your project please go ahead and create a ‘Form’ folder inside it. It is up to you to decide where the component should live. Once you created the folder let’s create the ‘index.js’ file.
