Minimalistic library to work with countries and timezones data.
The 'countries-and-timezones' npm package provides utilities for working with country and timezone data. It allows you to retrieve information about countries, their timezones, and perform various operations related to timezones.
Get Country Information
This feature allows you to retrieve information about a specific country using its ISO 3166-1 alpha-2 code. The returned object includes details such as the country's name, timezones, and other relevant data.
const ctz = require('countries-and-timezones');
const country = ctz.getCountry('US');
console.log(country);Get Timezone Information
This feature allows you to retrieve information about a specific timezone using its IANA timezone identifier. The returned object includes details such as the timezone's name, offset, and other relevant data.
const ctz = require('countries-and-timezones');
const timezone = ctz.getTimezone('America/New_York');
console.log(timezone);Get All Countries
This feature allows you to retrieve a list of all countries supported by the package. The returned object includes details for each country.
const ctz = require('countries-and-timezones');
const countries = ctz.getAllCountries();
console.log(countries);Get All Timezones
This feature allows you to retrieve a list of all timezones supported by the package. The returned object includes details for each timezone.
const ctz = require('countries-and-timezones');
const timezones = ctz.getAllTimezones();
console.log(timezones);Get Timezones for a Country
This feature allows you to retrieve a list of all timezones for a specific country using its ISO 3166-1 alpha-2 code. The returned array includes details for each timezone.
const ctz = require('countries-and-timezones');
const timezones = ctz.getTimezonesForCountry('US');
console.log(timezones);The 'moment-timezone' package is an extension for the 'moment' library to handle timezones. It provides utilities for parsing, manipulating, and displaying dates and times in various timezones. Compared to 'countries-and-timezones', 'moment-timezone' focuses more on date and time manipulation rather than country-specific data.
The 'timezone-support' package provides utilities for working with timezones and converting dates between different timezones. It includes features for parsing and formatting dates, as well as handling daylight saving time. Compared to 'countries-and-timezones', 'timezone-support' is more focused on date and time operations rather than providing country-specific information.
The 'world-countries' package provides a comprehensive list of countries with various details such as names, codes, and regions. It is similar to 'countries-and-timezones' in terms of providing country data, but it does not include timezone information.
