ajv-formats

Plugin for AJV that adds support for additional international formats and formats added in draft2019.

Currently, iri, iri-reference, idn-email, idn-hostname, and duration formats (added in draft 2019) are supported.

Installation

npm install ajv-formats

Usage

The main export is an apply function that patches an existing instance of ajv.

const Ajv = require('ajv');
const apply = require('ajv-formats');
const ajv = new Ajv();
apply(ajv);

let schema = {
  type: 'string',
  format: 'idn-email'
};
ajv.validate(schema, 'квіточка@пошта.укр')  // returns true

Alternately, the formats can be passed as an option when creating a new ajv instance.

const Ajv = require('ajv');
const formats = require('ajv-formats/formats');
const ajv = new Ajv({formats});

let schema = {
  type: 'string',
  format: 'idn-email'
};
ajv.validate(schema, 'квіточка@пошта.укр')  // returns true

Draft07

The library also provides a draft07 export to load only the formats relevant to draft07.

const Ajv = require('ajv');
const formats = require('ajv-formats/draft07');
const ajv = new Ajv({formats});

Formats

iri

The string is parsed with 'uri-js' and the scheme is checked against the list of known IANA schemes. If it's a 'mailto' schemes, all of the to: addresses are validated, otherwise we check there IRI includes a path and is an absolute reference.

iri-reference

All valid IRIs are valid. Fragments must have a valid path and of type "relative", "same-document" or "uri". If there is a scheme, it must be valid.

idn-email

isemail is used to check the validity of the email.

idn-hostname

The hostname is converted to ascii with punycode and checked for a valid tld.

duration

The string is checked against a regex.
