libraries for React applications<\/span><\/a>. It is lightweight and built for simple and easy projects due to its easy management, and simplicity to manage form state and behavior. It forms a unidirectional data flow to easily integrate the react components.<\/p>\n\n\n\nWhat is Formik?<\/h2>\n\n\n\n
Formik is also the library for the react application but it is more established for handling forms. It also provides a set of React components to manage the different forms which make it useful for work in complex and larger projects. It is designed with different features like state validation, state management, and form submission.<\/p>\n\n\n\n
Installation and Set up of React Hook Form<\/h2>\n\n\n\n
Getting started with the React Hook Form is a straightforward process. Begin by installing the library using npm:<\/p>\n\n\n\n
bash<\/p>\n\n\n\n
npm install react-hook-form<\/strong><\/p>\n\n\n\nOnce installed, you can import the required components and hooks into your React component and start using them.<\/p>\n\n\n\n
Installation and Set up of Formik<\/h2>\n\n\n\n
To use Formik, you need to install it via npm:<\/p>\n\n\n\n
bash<\/p>\n\n\n\n
npm install formik<\/strong><\/p>\n\n\n\nAfter installation, you can import the necessary components and hooks into your React component. Formik also requires the Yup library for validation, which you can install separately:<\/p>\n\n\n\n
bash<\/p>\n\n\n\n
npm install yup<\/strong><\/p>\n\n\n\nAPI and Usage of React Hook Form<\/h2>\n\n\n\n
React Hook Form provides a simple API and provides different functionality like \u201cuseForm\u201d. It is used to initialize and gain access to its methods and state. Here’s a basic example of using React Hook Form:<\/p>\n\n\n\n
jsx\n\nimport React from 'react';\n\nimport { useForm, Controller } from 'react-hook-form';\n\nfunction MyForm() {\n\n const { control, handleSubmit } = useForm();\n\n const onSubmit = (data) => {\n\n console.log(data);\n\n };\n\n return (\n\n <form onSubmit={handleSubmit(onSubmit)}>\n\n <Controller\n\n name=\"example\"\n\n control={control}\n\n defaultValue=\"\"\n\n render={({ field }) => <input {...field} \/>}\n\n \/>\n\n <button type=\"submit\">Submit<\/button>\n\n <\/form>\n\n );\n\n}<\/code><\/pre>\n\n\n\nAPI and Usage of Formik<\/h2>\n\n\n\n
Formik also provides the \u201cuseFormik\u201d to provide different functionalities. It is generally used to initialize the form and also provide a bag of helpers for managing the state.<\/p>\n\n\n\n
Let\u2019s understand by the following example: <\/p>\n\n\n\n
jsx\n\nimport React from 'react';\n\nimport { useFormik } from 'formik';\n\nfunction MyForm() {\n\n const formik = useFormik({\n\n initialValues: {\n\n example: '',\n\n },\n\n onSubmit: (values) => {\n\n console.log(values);\n\n },\n\n });\n\n return (\n\n <form onSubmit={formik.handleSubmit}>\n\n <input\n\n id=\"example\"\n\n name=\"example\"\n\n type=\"text\"\n\n onChange={formik.handleChange}\n\n value={formik.values.example}\n\n \/>\n\n <button type=\"submit\">Submit<\/button>\n\n <\/form>\n\n );\n\n}<\/code><\/pre>\n\n\n\n
