last commit vulnerabilities

A typescript type declaration of locales for use in Node and JavaScript Intl methods.

Type declarations are ideal for improving the developer experience (DX) yet do not add bloat to deployed code as the Typescript compiler (and other build tools) removes them.

tl;dr

A short explanation / quick reference:

import { TypesLocales } from '@zerodep/types.locales';

interface CustomInterface {
  locale: TypesLocales;
}

Install

This utility is available from multiple @zerodep packages, enabling developers to select the most appropriately sized package (for both kb and capability) for different use cases. We believe one size does not fit all or most. See @zerodep/app, @zerodep/utils and @zerodep/is.

// all @zerodep features, capabilities and utilities
npm install @zerodep/app

// all @zerodep "types" packages
npm install @zerodep/types

// only the types.locales declaration
npm install @zerodep/types.locales

Of course, you may use yarn, pnpm, or the package manager of your choice. Only npm examples are shown for brevity.

How to Use

Examples

// import from the most appropriate @zerodep package for your needs / specific use case (see the Install section above)
import { TypesLocales } from '@zerodep/types.locales';

// for Intl.DateTimeFormat (with required locale)
interface IntlDateTimeInterface {
  locale: TypesLocales | TypesLocales[];
}

// for Intl.DateTimeFormat with other values permitted
interface IntlDateTimeInterface {
  locale?: TypesLocales | TypesLocales[] | string | string[];
}

Semantically named - package and method names are easy to grok, remember, use, and read
Documented - actually useful documentation with examples and helpful tips
Intelligently Packaged - multiple npm packages of different sizes available allowing a menu or a-la-carte composition of capabilities
100% Tested - all methods and packages are fully unit tested
ESM & CJS - has both ecmascript modules and common javascript exports, both are fully tree-shakable
CDN Available - available on fast content delivery networks in UMD, CJS and ESM formats
FP Inspired - gently opinionated to encourage functional programming style for cleaner and more maintainable software
Predictably Versioned - semantically versioned for peace-of-mind upgrading, this includes changelogs
MIT Licensed - permissively licensed for maximum usability

Support

All @zerodep packages are built for the ES2020 specification. Should you need to support older environments you will need to add appropriate polyfills. All packages are tested on the following platforms/browsers:

Browsers

Chrome - last 2 major versions
Firefox - last 2 major versions
Safari - last 2 major versions
Edge - last 2 major versions
Android - last 2 major versions
iOS - last 2 major versions

Node

v16.x - Gallium LTS
v14.x - Fermium LTS

It is likely the package will work on other technologies and version, however development and testing effort is only spent on the above.

Semver

All @zerodep packages, including this one, adhere to Semantic Versioning practices:

major versions: correlates with breaking changes to one or more method signatures
minor versions: includes addition of new functionality or backwards-compatible software improvements
patch versions: are reserved for copy changes, documentation enhancements and bug fixes

The above said, a security best practice is to pin your software packages to specific versions and only upgrade to more recent releases after careful inspection of any CHANGELOG, release notes and all software changes.
