package uses [zod](https://www.npmjs.com/package/zod) to type check JSON values.\n\nIt includes type guards for each of the JSON types, as well as parse functions and corresponding types.\n\n## Contents\n\n- [Installation](#installation)\n- [Usage](#usage)\n  - [JSONValue](#jsonvalue)\n  - [JSONObject](#jsonobject)\n  - [JSONArray](#jsonarray)\n  - [JSONPrimitive](#jsonprimitive)\n  - [JSONOrderable](#jsonorderable)\n  - [String](#string)\n  - [Number](#number)\n  - [Boolean](#boolean)\n  - [Null](#null)\n  - [Undefined](#undefined)\n\n## Installation\n\n```sh\nyarn add types-json\n```\n\n```sh\nnpm install types-json\n```\n\n```sh\npnpm add types-json\n```\n\n## Usage\n\n### JSONValue\n\nWhen using `isJSONValue`, values which cannot be parsed or serialized properly using `JSON.parse` and `JSON.stringify` return false.\n\nSimilarly, when using `parseJSONValue`, invalid values return `undefined`.\n\nFinally, a zod schema provided representing the `JSONValue` type.\n\n```ts\nimport { isJSONValue, parseJSONValue, jsonValueSchema } from \"types-json\";\n\nisJSONValue(undefined); // false\nisJSONValue(null); // true\nisJSONValue(NaN); // false\nisJSONValue(Infinity); // false\nisJSONValue([1, 2, 3]); // true\nisJSONValue([1, 2, () =\u003e 3]); // false\n```\n\nOptional types are also provided:\n\n```ts\nimport { isOptionalJSONValue, parseOptionalJSONValue, optionalJSONValueSchema } from \"types-json\";\n\nisOptionalJSONValue(undefined); // true\nisOptionalJSONValue({ a: 1, b: undefined }); // true\n```\n\n### JSONObject\n\nJSONObject is a type guard and parse function for objects which can be parsed and serialized using `JSON.parse` and `JSON.stringify`.\n\n```ts\nimport {\n  isJSONObject,\n  parseJSONObject,\n  jsonObjectSchema\n} from \"types-json\";\n\nisJSONObject({ foo: \"bar\" }); // true\nisJSONObject({ foo: () =\u003e \"bar\" }); // false\nparseJSONObject({ foo: \"bar\" }); // true\nparseJSONObject({ foo: () =\u003e \"bar\" }); // undefined\n```\n\nOptional types are also provided. `OptionalJSONObject` includes `undefined`, while `NestedOptionalJSONObject` only allows for `undefined` values nested within the object:\n\n```ts\nimport {\n  isOptionalJSONObject,\n  parseOptionalJSONObject,\n  optionalJSONObjectSchema,\n  isNestedOptionalJSONObject,\n  parseNestedOptionalJSONObject,\n  nestedOptionalJSONObjectSchema\n} from \"types-json\";\n\nisOptionalJSONObject(undefined); // true\nisOptionalJSONObject({ a: 1, b: undefined }); // true\n\nisNestedOptionalJSONObject(undefined); // false\nisNestedOptionalJSONObject({ a: 1, b: undefined }); // true\n```\n\n### JSONArray\n\n```ts\nimport {\n  isJSONArray,\n  parseJSONArray,\n  jsonArraySchema,\n} from \"types-json\";\n\nisJSONArray([1]); // true\nisJSONArray([1, () =\u003e 2]); // false\nparseJSONArray([1]); // []\nparseJSONArray([1, () =\u003e 2]); // undefined\n```\n\nOptional types are also provided. `OptionalJSONArray` includes `undefined`, while `NestedOptionalJSONArray` only allows for `undefined` values nested within objects inside the array. Note that `undefined` values nested within arrays are not allowed, as they are not valid JSON:\n\n```ts\nimport {\n  isOptionalJSONArray,\n  parseOptionalJSONArray,\n  optionalJSONArraySchema,\n  isNestedOptionalJSONArray,\n  parseNestedOptionalJSONArray,\n  nestedOptionalJSONArraySchema\n} from \"types-json\";\n\nisOptionalJSONArray(undefined); // true\nisOptionalJSONArray([1, undefined]); // false\nisOptionalJSONArray([1, { a: 1, b: undefined }]); // true\n\nisNestedOptionalJSONArray(undefined); // false\nisNestedOptionalJSONArray([1, undefined]); // false\nisNestedOptionalJSONArray([1, { a: 1, b: undefined }]); // true\n```\n\n### JSONPrimitive\n\n```ts\nimport {\n  isJSONPrimitive,\n  parseJSONPrimitive,\n  jsonPrimitiveSchema\n} from \"types-json\";\n\nisJSONPrimitive(\"foo\"); // true\nisJSONPrimitive(1); // true\nisJSONPrimitive(true); // true\nisJSONPrimitive(null); // true\nisJSONPrimitive(undefined); // false\nisJSONPrimitive({}); // false\n```\n\nOptional types are also provided:\n\n```ts\nimport {\n  isOptionalJSONPrimitive,\n  optionalJSONPrimitiveSchema\n} from \"types-json\";\n\nisOptionalJSONPrimitive(\"foo\"); // true\nisOptionalJSONPrimitive(1); // true\nisOptionalJSONPrimitive(true); // true\nisOptionalJSONPrimitive(null); // true\nisOptionalJSONPrimitive(undefined); // true\nisOptionalJSONPrimitive({}); // false\n```\n\n### JSONOrderable\n\n`JSONOrderable` is a type for values which can be reasonably compared using operators such as `\u003e`, `\u003c`, `\u003e=`, and `\u003c=`:\n\n```ts\nimport {\n  isJSONOrderable,\n  parseJSONOrderable,\n  jsonOrderableSchema\n} from \"types-json\";\n\nisJSONOrderable(\"foo\"); // true\nisJSONOrderable(1); // true\nisJSONOrderable(true); // false\nisJSONOrderable(null); // false\nisJSONOrderable(undefined); // false\nisJSONOrderable({}); // false\nisJSONOrderable([]); // false\n```\n\nOptional types are also provided:\n\n```ts\nimport {\n  isOptionalJSONOrderable,\n  optionalJSONOrderableSchema\n} from \"types-json\";\n\nisOptionalJSONOrderable(\"foo\"); // true\nisOptionalJSONOrderable(1); // true\nisOptionalJSONOrderable(true); // false\nisOptionalJSONOrderable(null); // false\nisOptionalJSONOrderable(undefined); // true\nisOptionalJSONOrderable({}); // false\nisOptionalJSONOrderable([]); // false\n```\n\n### String\n\n```ts\nimport {\n  isString,\n  parseString,\n  stringSchema\n} from \"types-json\";\n\nisString(\"foo\"); // true\nisString(1); // undefined\nparseString(\"foo\"); // \"foo\"\nparseString(1); // undefined\n```\n\nOptional types are also provided:\n\n```ts\nimport {\n  isOptionalString,\n  optionalStringSchema\n} from \"types-json\";\n\nisOptionalString(\"foo\"); // true\nisOptionalString(undefined); // true\n```\n\n### Number\n\n```ts\nimport {\n  isNumber,\n  parseNumber,\n  numberSchema\n} from \"types-json\";\n\nisNumber(1); // true\nisNumber(\"1\"); // undefined\nparseNumber(1); // true\nparseNumber(\"1\"); // undefined\n```\n\nOptional types are also provided:\n\n```ts\nimport {\n  isOptionalNumber,\n  optionalNumberSchema\n} from \"types-json\";\n\nisOptionalNumber(1); // true\nisOptionalNumber(undefined); // true\n```\n\n### Boolean\n\n```ts\nimport {\n  isBoolean,\n  parseBoolean,\n  booleanSchema\n} from \"types-json\";\n\nisBoolean(true); // true\nisBoolean(\"true\"); // undefined\nparseBoolean(true); // true\nparseBoolean(\"true\"); // undefined\n```\n\nOptional types are also provided:\n\n```ts\nimport {\n  isOptionalBoolean,\n  optionalBooleanSchema\n} from \"types-json\";\n\nisOptionalBoolean(true); // true\nisOptionalBoolean(undefined); // true\n```\n\n### Null\n\n```ts\nimport {\n  isNull,\n  parseNull,\n  nullSchema\n};\n\nisNull(null); // true\nisNull(\"not null\"); // undefined\nparseNull(null); // null\nparseNull(\"not null\"); // undefined\n```\n\nOptional types are also provided:\n\n```ts\nimport {\n  isOptionalNull,\n  optionalNullSchema\n} from \"types-json\";\n\nisOptionalNull(null); // true\nisOptionalNull(undefined);
