JSON Schema validation for Human

Main goal of this library is to provide relevant error message like the following:

Enum Validation Error


$ yarn add better-avj-errors
$ # Or
$ npm i better-avj-errors


import Ajv from 'ajv';
// const Ajv = require('ajv');
import betterAjvErrors from 'better-avj-errors';
// const betterAjvErrors = require('better-avj-errors');

// You need to pass `jsonPointers: true`
const ajv = new Ajv({ jsonPointers: true });

// Load schema and data
const schema = ...;
const data = ...;

const validate = ajv.compile(schema);
const valid = validate(data);

if (!valid) {
  betterAjvErrors(schema, data, validate.errors);
