mock-browser-timezone

A Javascript library to mock the browser's timezone using ECMAScript Internationalization API.

What's different?

Many modern browsers use the Intl API to get the desired IANA timezone string which depicts the current browser timezone.

This library is specifically designed to mock the browser timezone, assisting to test the relevant code which uses the Intl API.

Installation

Using npm:

npm install mock-browser-timezone --save-dev

Using yarn:

yarn add mock-browser-timezone -D

API

registerTimezone: For mocking the browser's timezone represented in IANA timezone string.
registerAbbreviatedTimezone: For mocking the abbreviated timezone string. Factually, there can be a lot of ambiguity in determining abbreviated timezone since it highly depends on the daylight time and a single abbreviated string can also represent many other timezone values.
For a better read regarding the same: https://stackoverflow.com/tags/timezone/info.
reset: Used to bring back the mocked timezones to their original state.

Usage

For a better implementation of mock-browser-timezone, have a look at mock-browser-timezone.js file.

1const {
2  registerTimezone,
3  registerAbbreviatedTimezone,
4  reset,
5} = require('mock-browser-timezone');
6
7// Mocking the timezone using IANA timezone string.
8registerTimezone('Europe/Paris');
9
10reset(); // Default back to the orginal value.
11
12new Intl.DateTimeFormat().resolvedOptions().timeZone; // Europe/Paris
13
14registerAbbreviatedTimezone('CET');
15
16new Intl.DateTimeFormat([], {
17  timeZoneName: 'short',
18})
19  .formatToParts(date)
20  .find((locale) => locale.type === 'timeZoneName').value; // CET
21
22reset(); // Default back to the orginal abbreviated timezone value.
