Starting point is 00:00:00 This audio is presented by Hacker Noon, where anyone can learn anything about any technology. React 19. New tools to work with forms by Social Discovery Group. This article walks through the common struggles developers face when dealing with forms, and how React 19 finally introduces some long-awaited tools that make form handling cleaner, more declarative, and far less error-prone. Over the past six years in front-end development, from building complex form systems to integrating AI tools at SDG, I've written, debugged, and refactored more form code than I'd like to admit. And if you've ever built or maintained forms in React, you probably share that feeling.
Starting point is 00:00:40 They're deceptively simple, until they're not. In this article, I'll walk you through the common struggles developers face when dealing with forms, and how React 19 finally introduces some long-awaited tools that make form handling cleaner, more declarative, and far less error-prone. Sparkles, common challenges in form handling. Magnifying glass let's start with the pain points that every React developer has faced at least once. 1. Boilerplate code everywhere. Managing form state in React usually starts like this. Check mark it simple and perfectly fine for small forms. But as soon as you scale up, you end up drowning in repetitive state hooks, manual resets, and endless event. Prevent default, calls, each keystroke triggers a re-render, and managing
Starting point is 00:01:25 errors or pending states requires even more state variables. It's functional, but far from elegant. 2. Props drilling. When your form isn't just one component but a hierarchy of nested components, you end up passing props through every level. State, errors, loading flags, all drilled down through multiple layers. Downward trend this not only bloats the code but makes maintenance and refactoring painful. Face with Cold Sweat 3. Optimistic updates are hard, Ever tried to implement optimistic updates manually? That's when you show a success change in the UI immediately after a user action before the server actually confirms it.
Starting point is 00:02:04 It sounds easy but managing rollback logic when a request fails can be a real headache. Face with head bandage where do you store the temporary optimistic state? How do you merge and the N roll it back? Anti-clockwise arrows React 19 introduces something much cleaner for this. Use action state. A new way to handle form submission. One of the most exciting additions in React 19 is the equals equals asterisk use action state asterisk equals hook. It simplifies form logic by combining async form submission, state management, and loading indication, all in one place.
Starting point is 00:02:39 Bullseye hears what's happening. FN, your async function that handles the form submission. Initial state, the initial value of your form state, is pending, a built-in flag showing whether a submission is in progress. How it works, the async function passed to use action state automatically receives two arguments. You then hook it into your form like this. Now, when the form is submitted, react automatically, calls your async action. Updates asterisk, asterisk, state asterisk with the returned result, tracks the submission process via as pending. No more manual use state, prevent default, or reset logic.
Starting point is 00:03:17 React takes care awful of that. gear a note about start transition i f you decide to trigger the form action manually e g outside of the form's action prop wrap it with start transition otherwise react will warn you that an async update occurred outside a transition and as pending won't update properly why you'll love use action state check mark no need for multiple equals equals asterisk use state equals equals hooks check mark automatic pending state is pending check mark no event prevent default, required, checkmark auto form reset after successful submission. Form logic feels declarative again, just describe the action, not the wiring. Use form status. No more props drilling. Another powerful new hook. Use form status solves the problem of prop drilling and form trees. You can call this hook inside any child component of a form, and it will automatically connect to the parent form's state. example notice that submit button can access the forms data and pending status without a n y props being passed down gotchas to remember cross mark it doesn't work if you call it in the same component where the form is rendered it must be inside a child component cross mark it won't react to forms using on submit handlers it must be a form with an asterisk asterisk action asterisk asterisk prop warning as of now form method overrides inside buttons or inputs e g form Form method equals, get, don't work as expected.
Starting point is 00:04:46 The form still uses the main method. Bug I've opened an underscore underscore issue on GitHub underscore underscore to track that bug. Why use form status matters. Puzzle piece eliminates prop drilling in form trees. High voltage makes contextual decisions inside child components. Possible light bulb keeps components decoupled and cleaner. Use optimistic. Declarative optimistic U.I.
Starting point is 00:05:09 Finally, let's talk about one of my favorite additions. Use Optimistic. It brings built-in support for optimistic UI updates, making user interactions feel instant and smooth. The problem, imagine clicking, add to favorites. You want to show the update immediately, before the server response. Traditionally, you juggle between local state, rollback logic, and async requests. The solution, with Use Optimistic, it becomes declarative and minimal. If the server request fails, React automatically rolls back to the previous state. If it succeeds, the optimistic change stays. Important rule, don't mutate.
Starting point is 00:05:48 The update function you pass to use optimistic must be pure. Crossmark wrong. Check mark correct. Always return a new state object or array using with start transition. If you trigger optimistic updates outside of a forms action, wrap the min start transition. Otherwise, React will warn you that an optimistic update happened outside a transition. Light bulb benefits of use optimistic. High voltage instant UI feedback.
Starting point is 00:06:14 Anti-clockwise arrows automatic rollback on errors. Soap cleaner component logic. Hourglass fewer loading states needed. It's the kind of U.X improvement users feel, even if they don't know why your app suddenly feels so fast. Conclusions. React 19 significantly simplifies form handling, and for once, it's not about new syntax,
Starting point is 00:06:33 but real developer experience improvements. Rocket hears a quick recap of what to use and when. goal react 19 tool access form submission results use action state track pending submission as pending from use action state or pending from use form status access form state deep in children whose form status handle optimistic UI updates use optimistic these hooks make forms in react declarative composable and far less noisy if you've ever felt that working with forms in react meant writing boilerplate just to keep things in sync react 19 is the release you've been waiting for sparkles join a team that's shaping the few future of web experiences with React 19.
