Getting started

Get it from NPM

npm install tml-angular2

Include it in your angular app

//--- main.ts ---

//import the init 
import {init} from "tml-angular2";

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
if (process.env.ENV === 'production') {
    enableProdMode();
}

//init tml.js
init({
    key: "YOUR_APP_KEY",
    onLoad: function(app: any) {
        
        //bootstrap angular app after tml starts
        platformBrowserDynamic().bootstrapModule(AppModule);
    }
});

//--- app.module.ts ---

import { NgModule } from '@angular/core';
import { BrowserModule }  from '@angular/platform-browser';

//import the main module
import {TmlAngularModule} from "tml-angular2";

//add it to your module imports
@NgModule({
    imports: [
        BrowserModule,
        TmlAngularModule,
        // more modules
    ],
    declarations: [
      // ...
    ]
})

export class AppModule { }

Usage

Translation Examples:

Plain string:

<h1 tmlTr>Hello World</h1>

<h1 tmlTr="Hello World"></h1>

Variable:

// greetings: { hello: "Hello World", goodbye: "Bye now!" }
<h1 [tmlTr]="greetings.hello"></h1>

<h1 tmlTr>{{greetings.goodbye}}</h1>

With token data:

<h1 tmlTr [tmlValues]="{ user: user.name }">Welcome {user}</h1>

<div class="birthday" tmlTr [tmlValues]="{ name: user.name, age: user.age }">
  Happy birthday {name}, you're now {age} years old 
</div>

Mixed interpolation and token data:

//data:
ingredient: { quantity: 2, measurements: 'tablespoon', name: 'minced garlic' }

//template:
<h1 [tmlValues]="{ count: ingredient.quantity }" 
 tmlTr="{ count || {{ingredient.measurements}} } {{ingredient.name}}"></h1>

//translators see:
{count || tablespoon} minced garlic 

//result:
<h1>2 cups minced garlic</h1>

Phrase description

The description of a phrase is not mandatory, but it should be used in cases when the label alone is not sufficient enough to determine the meaning of the sentence being translated. As a general rule, you should always provide description to words, phrases and sentences that are only meaningful within a specific context. TML uses label and description together to create a unique key for each phrase. The description serves two purposes: it creates a unique key for each label and it also gives a hint to the translators for the context in which the label is used.

<h3 tmlTr tmlDescription="Link to invite your friends to join the site">Invite</h3>

<span tmlTr="Invite" tmlDescription="An invitation you received from your friend"></span>

Simple string translation with a pipe (for attributes, alts, titles)

<img alt="{{ 'amazing art' | trl }}" src="amazing-art.jpg" />

<input name="username" placeholder="{{ 'Enter username' | trl }}" />

Pipe with token data

<input type="number" name="age" 
 min="{{limits.minimalAge}}" 
 placeholder="{{ 'Enter your age (must be over {age})' | trl:{ age: limits.minimalAge }}" />

Pipe with token data and description

<input type="number" name="age" 
 min="{{limits.minimalAge}}" 
 placeholder="{{ 'Enter your age (must be over {age})' | trl:'Person age in years':{ age: limits.minimalAge }}" />

JS API

There is an injectable service called TranslateService which exposes some useful methods:

Current language:

currentLanguage() : Language

Change language by locale:

changeLanguage(locale: string, callback:Function<Language>)

Is the currently selected language right-to-left:

isRtl() : boolean

Translate string:

translate(label: string) : string

translate(label: string, description: string) : string

translate(label: string, description: string, values: {[key: string]: any}) : string

Language change event:

languageChanged$ : EventEmitter<Language>

//in your component
import {TranslateService} from "tml-angular2";

constructor(translateService: TranslateService) {
    
    translateService.currentLanguage();
    // { locale: 'en', native_name: 'English',  .... }
    
    translateService.isRtl();
    // false
    
    translateService.translate("Hello World");
    // Hello World
    
    translateService.changeLanguage('ru', (language) => {
      console.log(language);
      // {locale: 'ru', native_name: 'Русский', .... }
       
      translateService.translate("Hello World");
      // Привет Мир
    }
    
    translateService.languageChanged$.subscribe(language => { 
      console.log(language)
      // {locale: 'ru', native_name: 'Русский', .... }
    });

}
