How To Translate in Angular 8 Application

In this article, we will discuss Internationalization in Angular 8 using ngx-translate library.

NGX-Translate is an internationalization library for Angular. Internationalization is the process of translating an application into multiple languages. Using this library, we can translate our application language into multiple languages. This will work with not only static data, but dynamic data as well.

Prerequisites

• Basic knowledge of Angular.
• Node and NPM installed.
• Visual Studio Code.

If you’re new to Angular, then you can follow this tutorial on getting started.

Angular is a TypeScript-based, open source web application framework developed by Google. Angular is a platform for building mobile, desktop, and web applications.

TypeScript

TypeScript is an open source programming language developed and maintained by Microsoft. TypeScript is a superset of JavaScript that compiles to plain JavaScript.

Development Environment Required Software,

1. Node.js is an open source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a browser. See Node.js’ website for download and installation.
2. Angular CLI is a command line interface tool that we use to initialize, develop, and maintain Angular applications. Download this with the following command: npm install -g @angular/cli
3. Visual Studio Code — optional download link here.

Step 1

Create a new Angular project by using the following command. First, we need to set a path for creating a new angular app.

ng new MultilanguageApp

Creating a new Angular project

Now, open this project in Visual Studio Code. To open this in Visual Studio Code, choose the project path and run below command.

code .

Step 2

Now, install the ngx-translate library by using the following commands. We can install bootstrap and jquery for design.

npm install @ngx-translate/core --save

npm install @ngx-translate/http-loader --save

npm install bootstrap@4 jquery –save

Example of how to run the previous commands:

Output of previous commands

After installing the bootstrap package, we have to add reference of the CSS file on the styles.css file. To do this, fun the following command:

@import "~bootstrap/dist/css/bootstrap.css";

Step 3

Import the necessary modules into app.module.ts.

Installing necessary modules

Step 4

Now, expand the src folder and right-click on the Assets folder. Add a new folder under it and rename that to “i18” and add JSON files to this folder (based on how many languages you want to translate. I’m showing an example of two language English and French so I’m creating two files).

1. en.json
2. fr.json

The JSON file is a combination of a key-value pair.

Examples:

Example of key-value pairs

Step 5

Open the en.json file and paste the following code

{  
    "Addemployee": "Add-employee",  
    "Name": "Name",  
    "Email": "Email",  
    "PhoneNo": "Phone No",  
    "Submit": "Submit",  
    "Cancel": "Cancel",  
    "Home": "Home",  
    "Employee": "Employee",  
    "EmployeeList": "Employee List"  
}  

Step 6

Open fr.json file and paste the following code.

{  
    "Addemployee": "Ajouter employé",  
    "Name": "prénom",  
    "Email": "Email",  
    "PhoneNo": "Pas de téléphone",  
    "Submit": "Soumettre",  
    "Cancel": "Annuler",  
    "Home": "Accueil",  
    "Employee": "Employée",  
    "EmployeeList": "Liste des employés"  
}  

Step 7

Open the app.component.html file and paste the following code.

  

  

    
    Welcome to {{ title }}!  
    
    
      {{ lang }}  
    
  
  
    
      
      {{ 'Home' | translate }}  
      {{ 'Employee' | translate }}  
      {{ 'EmployeeList' | translate }}  
      [EmployeeList(Reload)](employeelist "EmployeeList(Reload)") -->  
      
    
    
      
    
  

Ex.

Declaring key and translating text

Step 8

Open the app.component.ts file and paste the following code.

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

@Component({  
  selector: 'app-root',  
  templateUrl: './app.component.html',  
  styleUrls: ['./app.component.css']  
})  
export class AppComponent {  
  title = 'MultilanguageApp';  

  constructor(  
    public translate: TranslateService) {  
    translate.addLangs(['en', 'fr']);  
    if (localStorage.getItem('locale')) {  
      const browserLang = localStorage.getItem('locale');  
      translate.use(browserLang.match(/en|fr/) ? browserLang : 'en');  
    } else {  
      localStorage.setItem('locale', 'en');  
      translate.setDefaultLang('en');  
    }  
  }  
  changeLang(language: string) {  
    localStorage.setItem('locale', language);  
    this.translate.use(language);  
  }  
} 

Ex.

Import service on constructor

Step 9

Run this command for hosting the application with default port 4200.

Running the command on port 4200

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

1. Installing Node.js and npm
2. Installing Angular CLI
3. Creating workspace
4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

• Node.js
• npm Package Manager

Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

1. npm -v

Installing Angular CLI

• Open Terminal/Command Prompt
• To install Angular CLI, run the below command:

1. npm install -g @angular/cli

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

• Using CLI
• Using Visual Studio Code

1. Using CLI

To create a workspace:

• Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
• Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:

1. Ng new YourAppName

• After running this command, it will prompt you to select from various options about the CSS and other functionalities.

• To leave everything to default, simply press the Enter or the Return key.

Wondering how to upgrade your skills in the pandemic? Here's a simple way you can do it.

Corona Virus Pandemic has brought the world to a standstill.

Countries are on a major lockdown. Schools, colleges, theatres, gym, clubs, and all other public places are shut down, the country’s economy is suffering, human health is on stake, people are losing their jobs and nobody knows how worse it can get.

Since most of the places are on lockdown, and you are working from home or have enough time to nourish your skills, then you should use this time wisely! We always complain that we want some ‘time’ to learn and upgrade our knowledge but don’t get it due to our ‘busy schedules’. So, now is the time to make a ‘list of skills’ and learn and upgrade your skills at home!

And for the technology-loving people like us, Knoldus Techhub has already helped us a lot in doing it in a short span of time!

If you are still not aware of it, don’t worry as Georgia Byng has well said,

“No time is better than the present”

– Georgia Byng, a British children’s writer, illustrator, actress and film producer.

No matter if you are a developer (be it front-end or back-end) or a data scientist, tester, or a DevOps person, or, a learner who has a keen interest in technology, Knoldus Techhub has brought it all for you under one common roof.

From technologies like Scala, spark, elastic-search to angular, go, machine learning, it has a total of 20 technologies with some recently added ones i.e. DAML, test automation, snowflake, and ionic.

How to upgrade your skills?

Every technology in Tech-hub has n number of templates. Once you click on any specific technology you’ll be able to see all the templates of that technology. Since these templates are downloadable, you need to provide your email to get the template downloadable link in your mail.

These templates helps you learn the practical implementation of a topic with so much of ease. Using these templates you can learn and kick-start your development in no time.

Apart from your learning, there are some out of the box templates, that can help provide the solution to your business problem that has all the basic dependencies/ implementations already plugged in. Tech hub names these templates as xlr8rs (pronounced as accelerators).

xlr8rs make your development real fast by just adding your core business logic to the template.

If you are looking for a template that’s not available, you can also request a template may be for learning or requesting for a solution to your business problem and tech-hub will connect with you to provide you the solution. Isn’t this helpful 🙂

Confused with which technology to start with?

To keep you updated, the Knoldus tech hub provides you with the information on the most trending technology and the most downloaded templates at present. This you’ll be informed and learn the one that’s most trending.

Since we believe:

“There’s always a scope of improvement“
