Converters and validators for https://day.js.org[Day.js] to integrate with the DefaultBinder of link:../..[mobx-binder].

== Prerequisites

The module needs the https://day.js.org/docs/en/plugin/custom-parse-format[customParseFormat] dayjs plugin to be installed

[source,js]
----
import customParseFormat from 'dayjs/plugin/customParseFormat'

dayjs.extend(customParseFormat)
----

== Conversion

The Day.js converter takes a https://day.js.org/docs/en/parse/string-format[format string] and converts displayed strings to Dayjs instances and vice versa.

If parsing fails, the validation fails with conversions.error.dayjs message key.

== Validation

Validators for Dayjs values have to be added to the binding chain after the converter.

.Example
[source,js]
----
import { DayjsConverter, DayjsValidators } from 'mobx-binder-dayjs'
...
binder.forField(fullName)
.isRequired()
.withConverter(new DayjsConverter('DD.MM.YYYY'))
.withValidator(DayjsValidators.dayInPast())
.bind()
----

Please check for supported validators and default error message keys link:src/validation/DayjsValidators.ts[here].
