🍋‍🟩 jsonlike

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

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 or Zod for full schema validation.
