About The Project

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

Built With

• react-jsonschema-form
• AJV
• TypeScript

Getting Started

Prerequisites

React JsonSchema Form Utils

• @rjsf/utils >= 5.0.0

yarn add @rjsf/core

Installation

yarn add @rjsf/validator-ajv8

Usage

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

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

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

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.

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.

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} />;

Similar packages

Other packages similar to @rjsf/validator-ajv8

ajv

AJV (Another JSON Schema Validator) is a popular JSON schema validator used for validating data against JSON schemas. It is highly performant and supports JSON Schema draft-07 and later. Compared to @rjsf/validator-ajv8, AJV is a more general-purpose validator and can be used outside of the React JSON Schema Form context.

jsonschema

The jsonschema package is a simple and lightweight JSON schema validator for JavaScript. It supports JSON Schema draft-04 and is easy to use for basic validation needs. While it is not as feature-rich as AJV, it provides a straightforward way to validate JSON data. Compared to @rjsf/validator-ajv8, jsonschema is less powerful but may be sufficient for simpler use cases.

is-my-json-valid

is-my-json-valid is a fast JSON schema validator that supports JSON Schema draft-04. It is designed for performance and can be used in both Node.js and browser environments. Compared to @rjsf/validator-ajv8, is-my-json-valid is focused on speed and may lack some of the advanced features provided by AJV.
