Usage

const { compile } = require("@node-rs/jsonschema");
const schema = {
 type: 'object',
 properties: {
 foo: { type: 'integer' },
 bar: { type: 'string' },
 },
 required: ['foo'],
 additionalProperties: false,
};
const input = JSON.stringify({
 foo: 1,
 bar: 'abc',
})
const exceptionInput = JSON.stringify({
 foo: 'abc',
 bar: 1,
})
const validator = compile(schema);
// check whether the input meet schema
const result = validator(input);
console.log(result); // true
const result = validator(exceptionInput);
console.log(result); // false
