wasm-i18n

A Rust and WebAssembly project template for managing internationalization (i18n) translations in web applications using wasm-pack.

About

This project provides a set of functions to manage internationalization (i18n) translations in web applications. It allows you to set, get, delete, and update translations for different locales, as well as load translations from a remote URL.

📦 Install

You can install the package via npm:

npm install wasm-i18n

Or if you are using yarn:

yarn add wasm-i18n

Make sure you have wasm-bindgen and wasm-pack set up in your project to build and run this package.

🚴 Usage

Example Usage

import { I18n } from 'wasm-i18n';

let i18n = new I18n();

async function run() {
    await i18n.setTranslations('en', {
        "welcome": "Hello {username}"
    });

    await i18n.setTranslations('en', {
        "test": {
            "data": '1111'
        }
    });

    const tr = i18n.getTranslations('en');
    console.log(tr);

    const translation = i18n.getTranslation('en', "welcome");
    console.log(translation);

    const formatted = i18n.formatTranslation('en', 'welcome', { username: 'Alice' });
    console.log(formatted);

    document.getElementById('welcome-message').innerText = formatted;

    const test = i18n.getTranslation('en', "test.data");
    console.log(test);
}

run();

API Documentation

setTranslations(locale: string, obj: any): void

Sets translations for a specific locale. If translations already exist for the locale, they will be merged with the new translations.

i18n.setTranslations('en', {
    "hello": "Hello",
    "world": "World"
});

getTranslations(locale: string): any

Gets all translations for a specific locale.

const translations = i18n.getTranslations('en');
console.log(translations);

delTranslations(locale: string): void

Deletes all translations for a specific locale.

i18n.delTranslations('en');

delTranslation(locale: string, key: string): void

Deletes a specific translation key for a locale.

i18n.delTranslation('en', 'hello');

getTranslation(locale: string, key: string): any

Gets the translation for a specific key in a locale.

const translation = i18n.getTranslation('en', 'hello');
console.log(translation);

hasTranslation(locale: string, key: string): boolean

Checks if a specific translation key exists in a locale.

const exists = i18n.hasTranslation('en', 'hello');
console.log(exists);

hasLocale(locale: string): boolean

Checks if a specific locale exists.

const exists = i18n.hasLocale('en');
console.log(exists);

formatTranslation(locale: string, key: string, args: any): string

Formats a translation string with provided arguments.

const formatted = i18n.formatTranslation('en', 'welcome', { username: 'Alice' });
console.log(formatted);

loadTranslations(url: string): Promise<void>

Loads translations from a remote URL.

await i18n.loadTranslations('https://example.com/translations.json');

getAllLocales(): Promise<Array<string>>

Gets all available locales.

const locales = await i18n.getAllLocales();
console.log(locales);

getAllTranslationsForLocale(locale: string): Promise<any>

Gets all translations for a specific locale.

const translations = await i18n.getAllTranslationsForLocale('en');
console.log(translations);

clearAllTranslations(): void

Clears all translations.

i18n.clearAllTranslations();

updateTranslation(locale: string, key: string, value: any): void

Updates a specific translation key for a locale.

i18n.updateTranslation('en', 'hello', 'Hello, World!');

getAllTranslations(): any

Gets all translations for all locales.

const all_translations = i18n.getAllTranslations();
console.log(all_translations);

hasKeyInTranslations(locale: string, key: string): boolean

Checks if a specific key exists in the translations for a locale.

const exists = i18n.hasKeyInTranslations('en', 'hello');
console.log(exists);
