Package Exports
- @stoplight/better-ajv-errors
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stoplight/better-ajv-errors) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
JSON Schema validation for Human 👨🎤
Main goal of this library is to provide relevant AJV error messages. It's a fork of great better-ajv-errors by Atlassian, with focus on being leaner.
Installation
$ yarn add @stoplight/better-ajv-errorsor
$ npm i @stoplight/better-ajv-errorsAlso make sure that you installed ajv package to validate data against JSON schemas.
Usage
First, you need to validate your payload with ajv. If it's invalid then you
can pass validate.errors object into better-ajv-errors.
import Ajv from 'ajv';
import betterAjvErrors from '@stoplight/better-ajv-errors';
// const Ajv = require('ajv');
// const betterAjvErrors = require('better-ajv-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) {
const output = betterAjvErrors(schema, validate.errors, {
propertyPath: [],
targetValue: data,
});
console.log(output);
