However this one has a few key benefits! While looking around for a good option, I had trouble finding a timezone select components which: 1. Adjusted the choices automatically with Daylight Savings Time (DST) 2. Didn't have a huge list of choices to scroll through when technically only 24 (ish) are necessary > [!IMPORTANT] > > ### Demo: [ndom91.github.io/react-timezone-select](https://ndom91.github.io/react-timezone-select/) > > This demo is also available in the `./examples` directory. Simply run `pnpm dev` in the root of the repository and the vite dev server will start, where you can then find the example app at [`localhost:3001`](http://localhost:3001). ## 🏗️ Installing ```bash npm install react-timezone-select react-select ``` > [!CAUTION] > The package `react-select` is optional. It is unnecessary if you're only using [the hook](#-timezone-hook). ## 🔭 Usage ```tsx import React, { useState } from "react" import ReactDOM from "react-dom" import TimezoneSelect, { type ITimezone } from "react-timezone-select" const App = () => { const [selectedTimezone, setSelectedTimezone] = useState( Intl.DateTimeFormat().resolvedOptions().timeZone, ) return (

react-timezone-select

Please make a selection

Output:

          {JSON.stringify(selectedTimezone, null, 2)}

) } const rootElement = document.getElementById("root") ReactDOM.render(, rootElement) ``` ## 🎨 Timezone Hook By default, `react-timezone-select` uses [`react-select`](https://github.com/jedwatson/react-select) as underlying select component. If you'd like to bring your own select component, you can use the `useTimezoneSelect` hook instead of the `TimezoneSelect` component to render the timezones using your self-provided select component. ```tsx import { useTimezoneSelect, allTimezones } from "react-timezone-select" const labelStyle = "original" const timezones = { ...allTimezones, "Europe/Berlin": "Frankfurt", } const customSelect = () => { const { options, parseTimezone } = useTimezoneSelect({ labelStyle, timezones }) return ( ) } ``` ## 🕹️ Props

Prop	Type	Default	Note
`value`	`string \| ITimezoneOption`	null	Initial/current Timezone
`onBlur`	`() => void`	null
`onChange`	`(timezone: ITimezoneOption) => void`	null
`labelStyle`	`'original' \| 'altName' \| 'abbrev' \| 'offsetHidden'`	`'original'`
`displayValue`	`'GMT' \| 'UTC'`	`'GMT'`	Prefix for the label (i.e. `"(GMT+2:00)"` or `"(UTC+2:00)"`)
`timezones`	`Record`	`allTimezones`
`currentDatetime`	`Date \| string`	null	Override datetime used to calculate timezone values (alternative to current datetime), useful for calculating different summer / winter times, etc.

#### Example `value`s: ```ts // string value='America/Juneau' // ITimezoneOption; i.e. `onChange` return value value={{ value: 'America/Juneau' label: '(GMT-8:00) Alaska, abbrev: 'AHST', offset: -8, altName: 'Alaskan Standard Time' }} ``` #### Example `timezones`: ```ts timezones={{ ...allTimezones, 'America/Lima': 'Pittsburgh', 'Europe/Berlin': 'Frankfurt', }} ``` ## ✨ Tips ### 👤 Default Users Timezone If you'd like the user's own timezone to be set as the initially selected option on render, we can make use of the new `Intl` browser API by setting the default state value to `Intl.DateTimeFormat().resolvedOptions().timeZone`. ```tsx const [timezone, setTimezone] = useState(Intl.DateTimeFormat().resolvedOptions().timeZone) ``` ### 🕒 Custom Timezones You can append custom choices of your own, or fully replace the listed timezone options. The `timezones` prop takes a dictionary of timezones in the format of "`{ tzIdentifier: Label }`" ([Timezone Identifiers](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)). ```tsx import TimezoneSelect, { type ITimezone, allTimezones } from 'react-timezone-select' const [selectedTimezone, setSelectedTimezone] = useState('Europe/Berlin') ``` The example above will include all original timezones and generate two additional choices: - `'(GMT-5:00) Pittsburgh'` - `'(GMT+1:00) Frankfurt'` We'll prepend the correct `(GMT...)` part to the generated label, you just have to provide the string you want in your label. Also, you can omit spreading in the `allTimezones` object for a select dropdown consisting of only your custom choices. ## 🚧 Contributing Pull requests are always welcome!
