ajvでJSON Schemaのvalidation.js

const schema = {
  properties: {
    smaller: {
      type: 'number',
    },
    larger: {
      type: 'number',
    },
  },
};

const data = {
  smaller: 5,
  larger: '1',
};

const Ajv = require('ajv');
const ajv = new Ajv();
const valid = ajv.validate(schema, data);
if (!valid) console.log(ajv.errors);
