<!-- ABOUT THE PROJECT -->

## About The Project

Exports `validator-ajv8` plugin for `react-jsonschema-form`.

### Built With

- [react-jsonschema-form](https://github.com/rjsf-team/react-jsonschema-form/)
- [AJV](https://github.com/ajv-validator/ajv/)
- [TypeScript](https://www.typescriptlang.org/)

<!-- GETTING STARTED -->

## Getting Started

### Prerequisites

#### React JsonSchema Form Utils

- `@rjsf/utils >= 5.0.0`

```bash
yarn add @rjsf/core
```

### Installation

```bash
yarn add @rjsf/validator-ajv8
```

<!-- USAGE EXAMPLES -->

## Usage

```tsx
import { RJSFSchema } from 'packages/utils/dist/index';
import Form from 'packages/core/dist/index';
import validator from '@rjsf/validator-ajv8';

const schema: RJSFSchema = {
  type: 'string',
};

<Form schema={schema} validator={validator} />;
```

or, using a more complex example using custom validator with custom formats

```tsx
import { RJSFSchema } from '@rjsf/utils';
import Form from '@rjsf/core';
import { customizeValidator } from '@rjsf/validator-ajv8';

const customFormats = {
  'phone-us': /\(?\d{3}\)?[\s-]?\d{3}[\s-]?\d{4}$/,
};

const validator = customizeValidator({
  customFormats,
});

const schema: RJSFSchema = {
  type: 'string',
  format: 'phone-us',
};

<Form schema={schema} validator={validator} />;
```

or, using a more complex example using a custom with additional meta schema

```tsx
import { RJSFSchema } from '@rjsf/utils';
import Form from '@rjsf/core';
import { customizeValidator } from '@rjsf/validator-ajv8';

const metaSchemaDraft06 = require('ajv/lib/refs/json-schema-draft-06.json');

const validator = customizeValidator({
  additionalMetaSchemas: [metaSchemaDraft06],
});

const schema: RJSFSchema = {
  $schema: 'http://json-schema.org/draft-06/schema#',
  type: 'string',
};

<Form schema={schema} validator={validator} />;
```

or, using a more complex example using custom validator config override options

```tsx
import { RJSFSchema } from '@rjsf/utils';
import Form from '@rjsf/core';
import { customizeValidator } from '@rjsf/validator-ajv8';

const validator = customizeValidator({
  ajvOptionsOverrides: {
    $data: true,
    verbose: true,
  },
});

const schema: RJSFSchema = {
  type: 'string',
};

<Form schema={schema} validator={validator} />;
```

or, using a more complex example using `ajv-formats` custom [format options](https://github.com/ajv-validator/ajv-formats).

```tsx
import { RJSFSchema } from '@rjsf/utils';
import Form from '@rjsf/core';
import { customizeValidator } from '@rjsf/validator-ajv8';

const validator = customizeValidator({
  ajvFormatOptions: {
    keywords: true,
    formats: ['date', 'time'],
  },
});

const schema: RJSFSchema = {
  type: 'string',
};

<Form schema={schema} validator={validator} />;
```

Finally, you can combine both additional meta schemas, custom formats, custom validator config override options and `ajv-formats` custom [format options](https://github.com/ajv-validator/ajv-formats).

```tsx
import { RJSFSchema } from '@rjsf/utils';
import Form from '@rjsf/core';
import { customizeValidator } from '@rjsf/validator-ajv8';

const metaSchemaDraft06 = require('ajv/lib/refs/json-schema-draft-06.json');

const customFormats = {
  'phone-us': /\(?\d{3}\)?[\s-]?\d{3}[\s-]?\d{4}$/,
};

const validator = customizeValidator({
  additionalMetaSchemas: [metaSchemaDraft06],
  customFormats,
  ajvOptionsOverrides: {
    $data: true,
    verbose: true,
  },
  ajvFormatOptions: {
    keywords: true,
    formats: ['date', 'time'],
  },
});

const schema: RJSFSchema = {
  $schema: 'http://json-schema.org/draft-06/schema#',
  type: 'string',
  format: 'phone-us',
};

<Form schema={schema} validator={validator} />;
```
