Forms in React

In this article, we’ll learn how Formik handles the state of the form data, validates the data, and handles form submission.

There are 2 approaches to access the value of an input element in React. In the first approach, named uncontrolled input, you access the value from a reference to the input element. The second approach, which I like because it doesn’t use references, is using a controlled input. Let’s see how to design controlled inputs using React hooks.

In this post, we are going to go through creating a few forms using Formik. Formik is a simple React/React Native form library that helps with handling form state, input validation, formatting, error handling, form submission, amongst other things.

I typically use plain React for forms. But I just converted a React form to use Formik.

Forms are fun. They start simple then blow up in your face.

A comprehensive comparison of the two libraries, with examples.

In this article, we’re going to take a look at some of the most popular solutions for form management and validation in React.

This article will show you a few different ways to handle form values in React. We’ll look at useState, custom Hooks, and, finally, no state at all!

When it comes to a multi-step form with React. I had trouble searching for related materials. On how to do it as I was implementing a survey form for one of my projects.

How to speed up your React form development with Formik.

We’re going to build a form together in this post. We’ll start with a React component then integrate Formik while demonstrating the way it handles state, validation, and submissions.

How to use react-hook-form to build clear and maintainable React forms.

Creating forms in React has become so easy now. We're going to learn how we can create custom forms using Hooks, and remove the necessity of downloading a ton of libraries for our applications.

In this tutorial, we’ll demonstrate how you can use uniforms to efficiently build schema-based forms in React.

Using the Name attribute in React Forms.

Using Netlify's built-in form handling with Gatsby should be simple and intuitive, but sadly it's not that simple. Well it is, it just requires some extra configuration not detailed in the documentation. So let’s get started!

In this article, we’ll take a step a back and discuss the challenges inherent to building forms with just React, such as state management and validation, and then how to solve them with the KendoReact Form component.

Looking to build a form component in React? It can get complicated, but there are tools we can use to make life easier. Read on for an example of how to build React forms with KendoReact, which easily takes care of the tedious aspects of React forms.

The goal of this post is to help you understand how to build more accessible React forms by using the popular react-icons library and the very accessible React components made available by the ReachUI library.

In this post, we will demonstrate how to build different performant React Native forms with native React Native UI components.

My biggest complaint about React is forms. Not because I think React took the wrong approach in how forms are implemented in React, but because it’s the most challenging problem in using React.

Using Formik to simplify the building of React forms, while staying away from magic.

Formik outperformed Redux Form in terms of size, best practices, and performance, but in this article, we will see how Formik measures up against the new kid on the block, React Hook Form. We will compare the two libraries and determine who will emerge as the victor in the end.

The more modern the application, the more likely developers will need to use special features and helpful hints to ensure demanding clients are happy with their user experience.

Components are the building blocks of React applications. It’s almost impossible to build a React application and not make use of components. It’s widespread to the point that some third-party packages provide you with components you can use to integrate functionality into your application.

Form Development in React comes down to three things: Data, Validations, and Submission. See how to handle these yourself or using Formik to make things simpler.

An alternative to some goodness of this.setState()

In this article I’m going to share with you on how I created my own form validation using React hooks.

Building forms with React involves setting up state as the container for user data and props as the means to control how state is updated using user input.

This final part of this series will focus on improving the user experience for the people that will use our validation library: the developers.

While the next part will focus on improving the developer experience, today’s article will focus on adding more features to what was created in Part 1.

Ever wondered how validation libraries work? This article will tell you how to build your very own validation library for React step by step.

Imagine that you, the good-looking developer (yes, I’m talking to you!), want to build an invitation form where users can add one or more email addresses to a list and send a message to all of them.

For almost every form that you create, you will want some sort of validation. In React, working with and validating forms can be a bit verbose, so in this article we are going to use a package called Formik to help us out!

There are multiple ways to upload a file using React. I’m going to explain the steps to upload a single file, multiple files, and files and data in React.

This is the continuation of our first part on Formik, the amazing Forms library for React.

Forms in the ReactJS can be a pain with all those repetition and business logic at the same time. Formik handles form state and Yup handles validation so we can focus our business logic.

In this article we will cover forms overview, discussing Forms in general and different form libraries.

Build a form validation engine using custom React Hooks, from scratch, without having to learn a single form library. Read on to learn how!

Use custom React Hooks to build forms that require half the code to write, are reusable, and are much easier to read. Read on to learn more!

Formik is an alternative and more efficient way of building React forms, keeping your React form logic organized and making testing, refactoring, and overall reasoning a breeze. We demonstrate how to leverage the features of Formik to build better React forms.

Join me as we walk through the easiest way I know how to add custom form validation in React in the fewest steps. Get up to speed creating your own custom form validation in your React components.

Last week I wrote an article about how we can build a form validation hook with React Hooks. But just after finishing the article I started to think “Ok, but we know that almost all the validation in this example could be done just using the DOM API”, and that is the story of how this article was born.

Today, let’s talk about forms. You have probably read a bunch of articles about state management in forms, this isn’t one of them. Instead, I’d like to talk about the design and API of forms.

The problem is that multi-step forms — while reducing perceived complexity on the front end — can feel complex and overwhelming to develop. But, I’m here to tell you that it’s not only achievable, but relatively straightforward using React as the base. So, that’s what we’re going to build together today!

There are several React hooks available right now and I plan to detail in some of them, but this article is about building a custom hook only using the useState hook to validate a form data.

Let’s go ahead to code a simple form first in a Stateful Component. We’ll rewrite the same form using Hooks and you can decide which one you like better.

In this tutorial, we’ll learn how to use React Dropzone to create an awesome file uploader. Keep reading to learn more about react-dropzone.

For any developer who envisions building an application, uploading images is a major component they have to take into account.

I regularly find inaccessible forms. In this post we’ll check out one of the common accessibility problems and fix it.

Form validation can be a tricky thing. There are a surprising number of edge cases as you get into the guts of a form implementation.

Implementing great forms can be a real time-waster. With just a few lines of JSON, you can use MSON to generate forms that perform real-time validation and have a consistent layout. And, MSON comes with a bunch of cool stuff like date pickers, masked fields and field collections.

An overview and walkthrough of fundamental React concepts, such as components, state, and props, as well as submitting forms, pulling data from an API, and deploying a React app to production.

The goal for this post is to get a better understanding of how to build forms in React.

Luckily, React forms don’t have to be awkward. In fact, they can be downright easy. And the trick is simple: you just need to understand that form state isn’t like other state.

So, you just got started with React and you’ve started building React apps and you’re wondering, how do I work with forms in React? Fret not.

Forms are pretty simple, right? Yeah! But there can be quite a few moving parts involved. A few things you might have to take care of…

I wrote my own react validation code, and am sharing it with you.

Come get a sneak peak at the new React Form v4 (currently in alpha).

In this stream, I'll walk you through how I built a useField hook using nothing but React Hooks. I'll also talk about why I think form state is so hard to handle in any UI and my plans to make it easier.

This video shows how to use the React Autosuggest library to show a dynamic list of countries which is loaded from a JSON endpoint. We'll use it within a Formik form and also cover how to tie Autosuggest into Formik and its validations.

This video covers how to use Formik to create and manage forms in React. We'll cover getting user input, validating it with Yup, and then handling the form submission.

In this video we'll cover Forms in Vanilla React (no additional packages).

In this talk, we’ll go over the existing solutions, how they stack up against each other, and what their limitations are.

In this talk, we'll explore the current React form landscape and learn how hooks and state machines can be used to create abstract models of complex forms that greatly reduce dependencies on restrictive form libraries or complex custom components.

We will explore an alternative way to manage forms using types and GraphQL.

Learn how to make a form in React using Typescript, Material UI, and Formik.

I'm going to be showing off a new library that I found that makes writing forms in React insanely simple.

I've got a contact form that I need to save to local storage so if people refresh the page and come back it's still around. Let's see how that goes!

My contact form leaves some things to be desired with the workflow on my end so I'm going to make a serverless function for my contact form so it'll do what I want it to do.

In this project we will build a React multi step form with multiple componenets including user & personal details, confirmation and success. We will use Material UI as well.

In this talk, we're going deep on forms in React. I'll explore managing validation, error messages, and working with 3rd-party inputs and introduce you to Formik, a tiny form helper that lets you do all the fun stuff I just mentioned and more.

Build simple forms with React controlled components and keep your API declarative.

In this video we build a contact form that will work with Netlify's form service.

React.js is a JavaScript library that can be used to build highly engaging web apps. In these apps, you often have to upload images or files. Learn how easy it actually is to do that!

Forms are hard in any framework, but they are extra complicated in React due to the recommended method of using "controlled inputs", inputs where all of their state is managed by the developer, not by the DOM or the React framework itself.

Forms in React can be verbose, repetitive, and messy. Managing the state of values, errors, and touched can make matters even worse. Formik adds a level of organization to your forms that allows for easier implementation, integrated validation, and a consistent interface to add third party components. Formik also makes it easy to abstract common form behavior into primitives that you can share and compose throughout your application.
