# JSON Schema Validator

  

    

    

    

    

    

  

This package implements a JSON Schema validator.

## Features

 - dead simple

 - faster than sonic

 - completely synchronous

 - circular reference detection & handling

 - errors if it finds any $refs - use the [dereferencer](https://github.com/json-schema-tools/dereferencer) before using the validator.

 - you get the json schema draft based on [meta-schema](https://github.com/json-schema-tools/meta-schema).

## Getting Started

```sh

npm install @json-schema-tools/validator

```

```typescript

import Validator, { ValidatorErrors, ReferenceError } from "@json-schema-tools/validator"

import { JSONSchema } from "@json-schema-tools/meta-schema";

const mySchema: JSONSchema = {

  title: "baz",

  type: "object",

  properties: {

    foo: {

      title: "foo",

      type: "array",

      items: { type: "string" }

    },

    bar: {

      title: "bar",

      anyOf: [

        { title: "stringerific", type: "string" },

        { title: "numberoo", type: "number" }

      ]

    }

  }

};

const valid = validator(mySchema, { foo: ["hello", "world" ], bar: 1 });

// true

const invalid = validator(mySchema, { foo: ["hello", "world" ], bar: true });

// invalid instanceof ValidationErrors === true

// invalid.errors is an array of the error types

```
