struct-police 👮‍♂️

Stop letting bad JSON roam free in your application.

struct-police is a lightweight, zero-dependency validator that strictly enforces schema rules. If your data doesn't fit, it goes to jail (throws an error).

Usage

import { police } from 'struct-police';

const schema = {
  type: 'object',
  required: ['id', 'username'],
  properties: {
    id: { type: 'number' },
    username: { type: 'string' }
  }
};

police(data, schema); // Safe or throws
