var Ajv = require('ajv')
// or ESM/TypeScript import

const schema = {
  type: 'string',
  minLength: 10,
}
var ajv = new Ajv() // options can be passed, e.g. {allErrors: true}
var validate = ajv.compile(schema)
var valid = validate('Jokcy')
console.log(valid)
if (!valid) console.log(validate.errors)
