OS locale detector (os-locale-s)

Its a light weight version that minimizes the dependency module of os-locale

Get the system locale

Useful for localizing your module or app.

POSIX systems: The returned locale refers to the LC_MESSAGE category, suitable for selecting the language used in the user interface for message translation.

Motivacion

I was creating a module package and needed to detect the locale.

At that time, I found a module os-locale that provides the corresponding function in the npm package.

I just wanted to detect locale token such as "cs", "de", "es", "fr" etc but
os-locale installs as many as 27 npm packages, including indirectly dependent modules

• e.g - yarn add os-locale

I just wanted to detect a simple locale token but thought this was overwork and decided to rewrite the code.

At the same time, has been migrate to TypeScript as well.

As a result, the number of npm packages installed in os-locale-s has been reduced to 3 including os-locale-s

Install

$ npm install os-locale-s

Usage

1// node (commenjs)
2const { osLocale } = require("os-locale-s");
3(async () => {
4    console.log(await osLocale());
5    //=> 'en-US'
6})();

1// ECMA module
2import { osLocale } from "os-locale-s";
3(async () => {
4    console.log(await osLocale());
5    //=> 'en-US'
6})();

API

osLocale(options?)

Returns a Promise for the locale.

osLocale.sync(options?)

Returns the locale.

options

Type: object

spawn

Type: boolean
Default: true

Set to false to avoid spawning subprocesses and instead only resolve the locale from environment variables. (process.env)

cache

Type: boolean
Default: true

Once the locale is detected, its value is retained and reused at the second and subsequent detections.

If set to false, the last held value will be ignored and do locale detection again (and the resulting value is not preserved)
