Well also see why its becoming a popular choice for building both simple and complex forms.
This is the default state of an input, in this case we do nothing special and let the browser handle the value of it. You will learn how to use and integrate this library with React. Uncontrolled Inputįirst we need to talk about uncontrolled inputs, where I say input it's also select or textarea. But they also support the way of managing Controlled components because many components cannot be treated as an Uncontrolled component. And React provides you with a lot of ways to do just that. Handling forms in JavaScript could be a difficult task, in this article we will learn how to tame them. React Hook Form (RHF) is using both Uncontrolled components and Controlled components. In React, mutable state is typically kept in the state property of components, and only updated with setState().
The same process is realized with errors object and touched object.Working with Forms in React without libraries This approach prevents you to type more code to convert an object from form to backend object type. Now, let’s consider a scenario where you have to manage a complex form state with multiple form inputs, which can be several different types like text, number, date. Sometimes you may be using hooks to manage the form state, using useState or useReducer. The same layers and properties are replicated in the final object, Hooks allow us to create smaller, composable, reusable more manageable React components. This process turns very easily to create forms from an object with several layers, It does not matter if the object is complex or has many properties or array, You can do much more complex form shapes by using nested forms, this can be done easily by setting your component name to one using a notation like account. UseForm provides a way to create complex forms easily, this hook returns an object of values in the same shape that it receives, this is possible using dot notation. React hooks are a game-changer when we think about forms, with hooks is very simple to create forms, and you can go on without libraries.īut when we wanna complex forms with many validations and complex objects with several layer and properties is appropriate to use a library form to manager the state of inputs and its validations.įor this reason, there is useForm, with useForm we can make greats forms and complex validations with less line code.
