 # ajv-formats
 
-Plugin for AJV that adds support for additional international formats and
-formats added in draft2019.
+JSON Schema formats for Ajv
 
-Currently, `iri`, `iri-reference`, `idn-email`, `idn-hostname`, and `duration`
-formats are supported. `duration` was added in draft 2019.

-## Installation
+## Usage
 
-```sh
-npm install ajv-formats
+```javascript
+import Ajv from "ajv"
+import addFormats from "ajv-formats"
+
+const ajv = new Ajv()
+addFormats(ajv)
 ```
 
-## Usage
+## Formats
 
-The default export is an `apply` function that patches an existing instance of
-`ajv`.
+The package defines these formats:
 
-```js
-const Ajv = require('ajv');
-const apply = require('ajv-formats');
-const ajv = new Ajv();
-apply(ajv); // returns ajv instance, allowing chaining
+- _date_: full-date according to [RFC3339](http://tools.ietf.org/html/rfc3339#section-5.6).
+- _time_: time with optional time-zone.
+- _date-time_: date-time from the same source (time-zone is mandatory).
+- _duration_: duration from [RFC3339](https://tools.ietf.org/html/rfc3339#appendix-A)
+- _uri_: full URI.
+- _uri-reference_: URI reference, including full and relative URIs.
+- _uri-template_: URI template according to [RFC6570](https://tools.ietf.org/html/rfc6570)
+- _url_ (deprecated): [URL record](https://url.spec.whatwg.org/#concept-url).
+- _email_: email address.
+- _hostname_: host name according to [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5).
+- _ipv4_: IP address v4.
+- _ipv6_: IP address v6.
+- _regex_: tests whether a string is a valid regular expression by passing it to RegExp constructor.
+- _uuid_: Universally Unique IDentifier according to [RFC4122](http://tools.ietf.org/html/rfc4122).
+- _json-pointer_: JSON-pointer according to [RFC6901](https://tools.ietf.org/html/rfc6901).
+- _relative-json-pointer_: relative JSON-pointer according to [this draft](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00).
 
-let schema = {
-  type: 'string',
-  format: 'idn-email',
-};
-ajv.validate(schema, 'квіточка@пошта.укр'); // returns true
-```
+See regular expressions used for format validation and the sources that were used in [formats.ts](https://github.com/ajv-validator/ajv-formats/blob/master/src/formats.ts).
 
-The `apply` function also accepts a second optional parameter to specify which
-formats to add to the `ajv` instance.
+**Please note**: JSON Schema draft-07 also defines formats `iri`, `iri-reference`, `idn-hostname` and `idn-email` for URLs, hostnames and emails with international characters. These formats are available in [ajv-formats-draft2019](https://github.com/luzlab/ajv-formats-draft2019) plugin.
 
-```js
-const Ajv = require('ajv');
-const apply = require('ajv-formats');
-const ajv = new Ajv();
+## Keywords to compare values: `formatMaximum` / `formatMinimum` and `formatExclusiveMaximum` / `formatExclusiveMinimum`
 
-// Install only the idn-email and iri formats
-apply(ajv, { formats: ['idn-email', 'iri'] });
-```
+These keywords allow to define minimum/maximum constraints when the format keyword defines ordering (`compare` function in format definition).
 
-The module also provides an alternate entrypoint `ajv-formats/formats` that
-works with the `ajv` constructor to add the formats to new instances.
+Rhese keywords are added to ajv instance when ajv-formats is used without options or with option `keywords: true`.
 
-```js
-const Ajv = require('ajv');
-const formats = require('ajv-formats/formats');
-const ajv = new Ajv({ formats });
+These keywords apply only to strings. If the data is not a string, the validation succeeds.
 
-let schema = {
-  type: 'string',
-  format: 'idn-email',
-};
-ajv.validate(schema, 'квіточка@пошта.укр'); // returns true
-```
+The value of keywords `formatMaximum`/`formatMinimum` and `formatExclusiveMaximum`/`formatExclusiveMinimum` should be a string or [\$data reference](https://github.com/ajv-validator/ajv/blob/v7-beta/docs/validation.md#data-reference). This value is the maximum (minimum) allowed value for the data to be valid as determined by `format` keyword. If `format` keyword is not present schema compilation will throw exception.
 
-Using the `ajv-formats/formats` entry point also allows cherry picking formats.
-Note the approach below only works for formats that don't contain a hypen `-` in
-the name. This approach may yield smaller packed bundles since it allows
-tree-shaking to remove unwanted validators and related dependencies.
+When these keyword are added, they also add comparison functions to formats `"date"`, `"time"` and `"date-time"`. User-defined formats also can have comparison functions. See [addFormat](https://github.com/ajv-validator/ajv/blob/v7-beta/docs/api.md#api-addformat) method.
 
-```js
-const Ajv = require('ajv');
-const { duration, iri } = require('ajv-formats/formats');
-const ajv = new Ajv({ formats: { duration, iri } });
-```
+```javascript
+require("ajv-formats")(ajv)
 
-## International formats
+const schema = {
+  type: "string",
+  format: "date",
+  formatMinimum: "2016-02-06",
+  formatExclusiveMaximum: "2016-12-27",
+}
 
-The library also provides an `idn` export to load only the international formats
-(ie. `iri`, `iri-reference`, `idn-hostname` and `idn-email`).
+const validDataList = ["2016-02-06", "2016-12-26"]
 
-```js
-const Ajv = require('ajv');
-const formats = require('ajv-formats/idn');
-const ajv = new Ajv({ formats });
+const invalidDataList = ["2016-02-05", "2016-12-27", "abc"]
 ```
 
-## Formats
+## Options
 
-### iri
+Options can be passed via the second parameter. Options value can be
 
-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.
+1. The list of format names that will be added to ajv instance:
 
-### iri-reference
+```javascript
+addFormats(ajv, ["date", "time"])
+```
 
-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.
+**Please note**: when ajv encounters an undefined format it throws exception (unless ajv instance was configured with `strict: false` option). To allow specific undefined formats they have to be passed to ajv instance via `formats` option with `true` value:
 
-Validating a IRI references is challenging since the syntax is so permissive.
-Basically, any URL-safe string is a valid IRI syntactically. I struggled to find
-[negative test cases](https://github.com/luzlab/ajv-formats/blob/master/index.test.js#L240)
-when writing the unit tests for IRI-references. Consider:
+```javascript
+const ajv = new Ajv((formats: {date: true, time: true})) // to ignore "date" and "time" formats in schemas.
+```
 
-- `google.com` is NOT a valid IRI because it does not include a scheme.
-- `file.txt` is a valid IRI-reference
-- `/this:that` is a valid IRI-reference
-- `this:that` is a NOT a valid IRI-reference
+2. Format validation mode (default is `"full"`) with optional list of format names and `keywords` option to add additional format comparison keywords:
 
-### idn-email
+```javascript
+addFormats(ajv, {mode: "fast"})
+```
 
-[`isemail`](https://www.npmjs.com/package/isemail) is used to check the validity
-of the email.
+or
 
-### idn-hostname
+```javascript
+addFormats(ajv, {mode: "fast", formats: ["date", "time"], keywords: true})
+```
 
-The hostname is converted to ascii with punycode and checked for a valid tld.
+In `"fast"` mode the following formats are simplified: `"date"`, `"time"`, `"date-time"`, `"uri"`, `"uri-reference"`, `"email"`. For example `"date"`, `"time"` and `"date-time"` do not validate ranges in `"fast"` mode, only string structure, and other formats have simplified regular expressions.
 
-### duration
+## Tests
 
-The string is checked against a regex.
+```bash
+npm install
+git submodule update --init
+npm test
+```
