Installation

First you need to install the npm module:

npm i ng-trans --save

Usage

1. Build node server :

You should create simple server trans-server.js file in angular project root or any project using the following options

after using npm i ng-trans --save to install package create the simple file

var trans = require('ng-trans');  
trans({  
  src: 'src/app',  
  transPath: 'src/assets/trans'  
});

2. Create HTML and TS files :

Now you should customize your component files like as the following example

<p>{{'%WelcomePage.HelloWorld.{"en":"Hello World","fr":"Bonjour le monde"}%@trans' | translate}}</p>

Notes: 1- the line should start with % and end with %@trans 2- important: the translate line should ended with object with translated types for example en and fr or en and ar and you make sure add . in between object and last key in translate levels .{"en":""} . 3- you can use multiple levels levelOne.LevelTwo.LevelThree. ....... 4- you can write object keys camel case welcomePage or upper letter WELCOME_PAGE or welcome_page or any typing ways and output will be WELCOME_PAGE. 5. you can add trans value in en as same as last key in object WelcomePage.HelloWorld.{"en":"HelloWorld"} and compiler will rewrite it as human writes Hello wold.

import {Component} from '@angular/core';
import {TranslateService} from '@ngx-translate/core';

@Component({
    selector: 'app',
   .....
})
export class AppComponent {
    validation = {isRequeried: '%welcomePAge.validation{"en":"%this field is required%@trans","fr":"Ce champ est requis"'};

    constructor(translate: TranslateService) {
    }
}

3. Run:

When you run node trans-server.js in project root then open project files you will found % %@trans removed and last object also.

import {Component} from '@angular/core';
import {TranslateService} from '@ngx-translate/core';

@Component({
    selector: 'app',
   .....
})
export class AppComponent {
    validation = {isRequeried: 'WELCOME_PAGE.VALIDATION';

    constructor(translate: TranslateService) {
    }
}

and HTML

<p>{{'WELCOME_PAGE.HELLO_WORLD' | translate}}</p>

and you can find new files in translate files path en.json and fr.json and map

{
	WELCOME_PAGE:{
		HELLO_WORLD:"Hello World",
		VALIDATION:"this field is required"
		
	}
}

If you need add more translate item do it without write old items or if you need update old one you need only set it in trans mode % .... %@trans and it will overwrite in translated files.

3. Cli:

Also you can use commend lines to build translate files without install it in project package use the following commend to download project in your workspace:

git clone https://gitlab.com/ahmedharby9/transapp.git

after download project copy your source files in src in project and create trans directory and then run commend line node app.js src 'src' transPath 'trans' you can also use node app.js -h or node app.js --help to know more about options.

Finally, this package used to reducing translation time during development work and providing you with the ideal solution in creating an integrated translation in many languages in the simplest way.
