Just enough JavaScript object validation.

**jsonlike** is a tiny < 1kB library used to validate JavaScript objects against a JSON-like schema.

It can:

* Match properties by primitive types

* Match arrays of single type values

* Match nested objects

## Usage

```ts

import {jsonlike} from '@dbushell/jsonlike';

const json = JSON.parse(`{

  "greeting": "Hello, World!",

  "items": [{"id": 1}, {"id": 2}, {"id": 3}]

}`);

const valid = jsonlike(json, {

  greeting: 'string',

  items: [{id: 'number'}]

});

```

## Notes

Use [Ajv](https://github.com/ajv-validator/ajv) or [Zod](https://github.com/colinhacks/zod) for full schema validation.
