zod-joda

JS-Joda integration for Zod validation library

This library adds additional types for Zod to parse and validate dates, times and durations as js-joda types. This library has support for both zod v4 and zod/v4/mini.

Installation

npm install zod-joda @js-joda/core zod

Quick Start

Import the schema types from this package. You can either import individual types or import all types via convenience method:

import {zj} from 'zod-joda';

For zod/v4/mini, import from the mini sub-path:

import {zj} from 'zod-joda/mini';

This library supplies the following types:

• zj.duration()
• zj.localDate()
• zj.localDateTime()
• zj.localTime()
• zj.zonedDateTime()

All constructors except duration take an optional object with a dateTimeFormatter property, which allows you to change the default behavior of how dates and times will be parsed. By default, every value should be in an ISO 8601 format.
