### Adapt Zod Schema to Formik validationSchema with TypeScript

Source: https://github.com/robertlichtnow/zod-formik-adapter/blob/master/README.md

Demonstrates how to use the `toFormikValidationSchema` function to adapt a Zod schema for Formik's `validationSchema` prop. This requires importing `z`, `Formik`, and the adapter function. The example shows a basic Zod object schema and its integration into a Formik component.

```tsx
import {
  z
} from 'zod';
import { Formik } from 'formik';
import {
  toFormikValidationSchema
} from 'zod-formik-adapter';

const Schema = z.object({
  name: z.string(),
  age: z.number(),
});

const Component = () => (
  <Formik
    validationSchema={toFormikValidationSchema(Schema)}
  >
    {...}
  </Formik>
);
```

### Adapt Zod Schema to Formik validate prop with TypeScript

Source: https://github.com/robertlichtnow/zod-formik-adapter/blob/master/README.md

Illustrates the usage of the `toFormikValidate` function to adapt a Zod schema for Formik's `validate` prop. Similar to `validationSchema`, it requires importing `z`, `Formik`, and the adapter function. The example defines a Zod object schema and applies it using the `validate` prop.

```tsx
import {
  z
} from 'zod';
import { Formik } from 'formik';
import {
  toFormikValidate
} from 'zod-formik-adapter';

const Schema = z.object({
  name: z.string(),
  age: z.number(),
});

const Component = () => (
  <Formik
    validate={toFormikValidate(Schema)}
  >
    {...}
  </Formik>
);
```

### Handle Zod Validation Errors in Formik (TypeScript)

Source: https://context7.com/robertlichtnow/zod-formik-adapter/llms.txt

This example demonstrates how to use the `ValidationError` class from `zod-formik-adapter` to catch and process validation errors when integrating Zod with Formik. It shows how to extract structured error messages and their corresponding paths from the `ValidationError` object. Dependencies include Zod and `zod-formik-adapter`.

```tsx
import { z } from 'zod';
import { toFormikValidationSchema, ValidationError } from 'zod-formik-adapter';

const LoginSchema = z.object({
  email: z.string().email(),
  password: z.string().min(6)
});

async function validateLoginForm(values: unknown) {
  const { validate } = toFormikValidationSchema(LoginSchema);

  try {
    await validate(values);
    console.log('Validation passed');
    return null;
  } catch (error) {
    if (error instanceof ValidationError) {
      console.log('Validation failed:', error.message);
      console.log('Error details:', error.inner);
      // error.inner is an array of { path: string, message: string }
      // Example: [
      //   { path: 'email', message: 'Invalid email address' },
      //   { path: 'password', message: 'String must contain at least 6 character(s)' }
      // ]
      return error.inner;
    }
    throw error;
  }
}

// Usage example
const invalidData = { email: 'not-an-email', password: '123' };
validateLoginForm(invalidData).then(errors => {
  if (errors) {
    errors.forEach(err => {
      console.log(`Field "${err.path}" error: ${err.message}`);
    });
  }
});
```

### Formik Product Form with Zod Validation (TypeScript)

Source: https://context7.com/robertlichtnow/zod-formik-adapter/llms.txt

A React `ProductForm` component built with Formik and Zod, utilizing `zod-formik-adapter` for validation. It defines a `ProductSchema` with various field types and demonstrates custom parse context with `abortEarly: false` to collect all validation errors.

```tsx
import React from 'react';
import { Formik, Form, Field } from 'formik';
import { z } from 'zod';
import { toFormikValidate } from 'zod-formik-adapter';

const ProductSchema = z.object({
  name: z.string().min(1, 'Product name required'),
  price: z.number().positive('Price must be positive'),
  category: z.enum(['electronics', 'clothing', 'food', 'other']),
  tags: z.array(z.string()).min(1, 'At least one tag required'),
  inStock: z.boolean(),
  metadata: z.record(z.string(), z.any()).optional()
});

type ProductFormValues = z.infer<typeof ProductSchema>;

const ProductForm: React.FC = () => {
  const initialValues: ProductFormValues = {
    name: '',
    price: 0,
    category: 'other',
    tags: [],
    inStock: true,
    metadata: {}
  };

  // Custom parse context can be used to pass additional validation options
  const parseContext = {
    // Zod v4 parse context options can be specified here
    abortEarly: false // Process all validation errors
  };

  return (
    <Formik
      initialValues={initialValues}
      validate={toFormikValidate(ProductSchema, parseContext)}
      onSubmit={(values) => {
        console.log('Product data:', values);
        // API submission logic
      }}
      validateOnChange={true}
      validateOnBlur={true}
    >
      {({ errors, values, setFieldValue }) => (
        <Form>
          <div>
            <label>Product Name</label>
            <Field name="name" />
            {errors.name && <span className="error">{errors.name}</span>}
          </div>

          <div>
            <label>Price</label>
            <Field name="price" type="number" step="0.01" />
            {errors.price && <span className="error">{errors.price}</span>}

            </Field>
            {errors.category && <span className="error">{errors.category}</span>}
          </div>

          <div>
            <label>Tags (comma-separated)</label>
            <input
              name="tags"
              value={values.tags.join(', ')}
              onChange={(e) => {
                const tags = e.target.value.split(',').map(t => t.trim()).filter(Boolean);
                setFieldValue('tags', tags);
              }}
            />
            {errors.tags && <span className="error">{errors.tags}</span>}
          </div>

          <div>
            <label>
              <Field type="checkbox" name="inStock" />
              In Stock
            </label>
          </div>

          <button type="submit">Add Product</button>
        </Form>
      )}
    </Formik>
  );
};

export default ProductForm;

### Convert Zod Schema to Formik Validation Function (TypeScript)

Source: https://context7.com/robertlichtnow/zod-formik-adapter/llms.txt

This function converts a Zod schema into a validation function suitable for Formik's `validate` prop. It takes a Zod schema as input and returns a function that Formik can use to validate form data. Validation errors are returned as an object, or undefined if validation passes. Dependencies include React, Formik, and Zod.

```tsx
import React from 'react';
import { Formik, Form, Field } from 'formik';
import { z } from 'zod';
import { toFormikValidate } from 'zod-formik-adapter';

// Define a nested object schema
const AddressSchema = z.object({
  street: z.string().min(1, 'Street is required'),
  city: z.string().min(1, 'City is required'),
  zipCode: z.string().regex(/^\d{5}(-\d{4})?$/, 'Invalid ZIP code'),
  country: z.string().min(2, 'Country code required')
});

const ProfileSchema = z.object({
  firstName: z.string().min(1, 'First name is required'),
  lastName: z.string().min(1, 'Last name is required'),
  phone: z.string().regex(/^\+?[\d\s-()]+$/, 'Invalid phone number').optional(),
  address: AddressSchema,
  preferences: z.object({
    newsletter: z.boolean(),
    notifications: z.boolean()
  }).optional()
});

type ProfileFormValues = z.infer<typeof ProfileSchema>;

const ProfileForm: React.FC = () => {
  const initialValues: ProfileFormValues = {
    firstName: '',
    lastName: '',
    phone: '',
    address: {
      street: '',
      city: '',
      zipCode: '',
      country: 'US'
    },
    preferences: {
      newsletter: false,
      notifications: true
    }
  };

  return (
    <Formik
      initialValues={initialValues}

### Convert Zod Schema to Formik Validation Schema (TypeScript)

Source: https://context7.com/robertlichtnow/zod-formik-adapter/llms.txt

Converts a Zod schema into a Formik-compatible validation schema. This function is essential for using Zod's validation logic within Formik forms. It handles asynchronous validation and error transformations, ensuring proper typing for form values. Requires 'zod' and 'formik' libraries.

```tsx
import React from 'react';
import { Formik, Form, Field, ErrorMessage } from 'formik';
import { z } from 'zod';
import { toFormikValidationSchema } from 'zod-formik-adapter';

// Define a comprehensive Zod schema
const UserSchema = z.object({
  username: z.string()
    .min(3, 'Username must be at least 3 characters')
    .max(20, 'Username must not exceed 20 characters'),
  email: z.string().email('Invalid email address'),
  age: z.number()
    .min(18, 'Must be at least 18 years old')
    .max(120, 'Invalid age'),
  password: z.string()
    .min(8, 'Password must be at least 8 characters')
    .regex(/[A-Z]/, 'Password must contain at least one uppercase letter'),
  confirmPassword: z.string()
}).refine((data) => data.password === data.confirmPassword, {
  message: "Passwords don't match",
  path: ["confirmPassword"],
});

type UserFormValues = z.infer<typeof UserSchema>;

const UserRegistrationForm: React.FC = () => {
  const initialValues: UserFormValues = {
    username: '',
    email: '',
    age: 18,
    password: '',
    confirmPassword: ''
  };

  const handleSubmit = async (values: UserFormValues) => {
    console.log('Form submitted:', values);
    // API call would go here
  };

  return (
    <Formik
      initialValues={initialValues}
      validationSchema={toFormikValidationSchema(UserSchema)}
      onSubmit={handleSubmit}
    >
      {({ errors, touched, isSubmitting }) => (
        <Form>
          <div>
            <label htmlFor="username">Username</label>
            <Field name="username" type="text" />
            <ErrorMessage name="username" component="div" />
          </div>

          <div>
            <label htmlFor="email">Email</label>
            <Field name="email" type="email" />
            <ErrorMessage name="email" component="div" />
          </div>

          <div>
            <label htmlFor="age">Age</label>
            <Field name="age" type="number" />
            <ErrorMessage name="age" component="div" />
          </div>

          <div>
            <label htmlFor="password">Password</label>
            <Field name="password" type="password" />
            <ErrorMessage name="password" component="div" />
          </div>

          <div>
            <label htmlFor="confirmPassword">Confirm Password</label>
            <Field name="confirmPassword" type="password" />
            <ErrorMessage name="confirmPassword" component="div" />
          </div>

          <button type="submit" disabled={isSubmitting}>
            Register

### Validate Complex Nested Forms with Zod and Formik in React

Source: https://context7.com/robertlichtnow/zod-formik-adapter/llms.txt

This TypeScript/React code defines a Zod schema for a project form, including nested team members and their contacts. It then uses `zod-formik-adapter` to create a Formik validation schema and renders a form with dynamic field arrays for team members and contacts. Input: Form data. Output: Validated form data or errors.

```tsx
import React from 'react';
import { Formik, Form, Field, FieldArray } from 'formik';
import { z } from 'zod';
import { toFormikValidationSchema } from 'zod-formik-adapter';

const ContactSchema = z.object({
  type: z.enum(['email', 'phone', 'social']),
  value: z.string().min(1, 'Contact value required')
});

const TeamMemberSchema = z.object({
  name: z.string().min(1, 'Name required'),
  role: z.string().min(1, 'Role required'),
  contacts: z.array(ContactSchema).min(1, 'At least one contact required')
});

const ProjectSchema = z.object({
  title: z.string().min(3, 'Title must be at least 3 characters'),
  description: z.string().max(500, 'Description too long'),
  startDate: z.string().refine((date) => !isNaN(Date.parse(date)), {
    message: 'Invalid date format'
  }),
  team: z.array(TeamMemberSchema).min(1, 'Project must have at least one team member')
});

type ProjectFormValues = z.infer<typeof ProjectSchema>;

const ProjectForm: React.FC = () => {
  const initialValues: ProjectFormValues = {
