Basics

import React from "react";
import { Form, Input } from "@rocketseat/unform";

function App() {
  function handleSubmit(data) {
    console.log(data);

    /**
     * {
     *   email: '[e-mail]',
     *   password: "123456"
     * }
     */
  };

  return (
    <Form onSubmit={handleSubmit}>
      <Input name="email" />
      <Input name="password" type="password" />

      <button type="submit">Sign in</button>
    </Form>
  );
}

nested fields

import React from "react";
import { Form, Input, Scope } from "@rocketseat/unform";

function App() {
  function handleSubmit(data) {
    console.log(data);

    /**
     * {
     *   name: 'Diego',
     *   address: { street: "Name of street", number: 123 }
     * }
     */
  };

  return (
    <Form onSubmit={handleSubmit}>
      <Input name="name" />

      <Scope path="address">
        <Input name="street" />
        <Input name="number" />
      </Scope>

      <button type="submit">Save</button>
    </Form>
  );
}

Initial data

import React from "react";
import { Form, Input, Scope } from "@rocketseat/unform";

function App() {
  const initialData = {
    name: 'John Doe',
    address: {
      street: 'Sample Avenue',
    },
  }

  function handleSubmit(data) {};

  return (
    <Form onSubmit={handleSubmit} initialData={initialData}>
      <Input name="name" />

      <Scope path="address">
        <Input name="street" />
        <Input name="number" />
      </Scope>

      <button type="submit">Save</button>
    </Form>
  );
}

Validation

import React from "react";
import { Form, Input } from "@rocketseat/unform";
import * as Yup from 'yup';

const schema = Yup.object().shape({
  email: Yup.string()
    .email('Custom invalid email message')
    .required('Custom required message'),
  password: Yup.string().min(4).required(),
})

function App() {
  function handleSubmit(data) {};

  return (
    <Form schema={schema} onSubmit={handleSubmit}>
      <Input name="email" />
      <Input name="password" type="password" />

      <button type="submit">Save</button>
    </Form>
  );
}

Manipulate data

import React, { useState } from "react";
import { Form, Input } from "@rocketseat/unform";
import * as Yup from 'yup';

const schema = Yup.object().shape({
  name: Yup.string().required(),
  email: Yup.string().email().required(),
  password: Yup.string().when('$updatePassword', {
    is: true,
    then: Yup.string().min(4).required(),
    otherwise: Yup.string().strip(true)
  }),
})

function App() {
  const [updatePassword, setUpdatePassword] = useState(false);

  const initialData = {
    name: 'John Doe',
    email: '[e-mail]',
  }

  function handleSubmit(data) {};

  return (
    <Form
      schema={schema}
      initialData={initialData}
      context={{ updatePassword }}
      onSubmit={handleSubmit}
    >
      <Input name="name" />
      <Input name="email" />

      <input
        type="checkBox"
        name="Update Password"
        checked={updatePassword}
        onChange={e => setUpdatePassword(e.target.checked)}
      />
