Advanced tools
Package description
@rjsf/validator-ajv8 is a validation package for React JSON Schema Form (RJSF) that uses AJV version 8 for JSON schema validation. It allows you to validate form data against a JSON schema, ensuring that the data conforms to the specified structure and constraints.
Schema Validation
This feature allows you to validate data against a JSON schema. The code sample demonstrates how to compile a schema and validate data using AJV.
const Ajv = require('ajv');
const ajv = new Ajv();
const schema = {
type: 'object',
properties: {
name: { type: 'string' },
age: { type: 'integer' }
},
required: ['name', 'age']
};
const validate = ajv.compile(schema);
const data = { name: 'John', age: 30 };
const valid = validate(data);
if (!valid) console.log(validate.errors);Custom Keywords
This feature allows you to add custom validation keywords to your schema. The code sample shows how to add a custom keyword 'isPositive' and use it in a schema.
const Ajv = require('ajv');
const ajv = new Ajv();
ajv.addKeyword('isPositive', {
type: 'number',
validate: (schema, data) => data > 0
});
const schema = {
type: 'object',
properties: {
positiveNumber: { type: 'number', isPositive: true }
}
};
const validate = ajv.compile(schema);
const data = { positiveNumber: 10 };
const valid = validate(data);
if (!valid) console.log(validate.errors);Error Messages
This feature provides detailed error messages when validation fails. The code sample demonstrates how to enable all error messages and validate data that does not meet the schema requirements.
const Ajv = require('ajv');
const ajv = new Ajv({ allErrors: true });
const schema = {
type: 'object',
properties: {
name: { type: 'string' },
age: { type: 'integer', minimum: 18 }
},
required: ['name', 'age']
};
const validate = ajv.compile(schema);
const data = { name: 'John', age: 16 };
const valid = validate(data);
if (!valid) console.log(validate.errors);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.
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 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.

Exports validator-ajv8 plugin for react-jsonschema-form.
@rjsf/utils >= 5.0.0yarn add @rjsf/core
yarn add @rjsf/validator-ajv8
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} />
