Internationalization (I18N) in Angular with Transloco

In this post, I’m going to talk about internationalization and how to implement it in an Angular application with the help of a neat library called Transloco.

What is Internationalization (I18N)?

I think it’s best to start by explaining what internationalization (i18n for short - first letter of the word followed by the number of letters until the last letter of the word) is and why it is so important.

Internationalization is the process of adapting a software application to allow it to be easily used in multiple countries. There is a common misconception that this means that all text within an application must have translations for multiple languages; however, full i18n goes beyond just plain text in your application.

In many western countries, red is commonly used to signal danger. However, in some regions throughout the world, red is seen as a positive color.

Likewise, in many western countries, text is read from left to right; however, in some languages text is read from right to left.

Another example of where i18n comes into play is in images. If an image in your application contains text, to fully support i18n, it may be appropriate to generate multiple images each with the correct translations for the languages you support in your application. You would then need to serve the correct image depending on what country the user using your application is located in.

Naomi Meyer gave a brilliant talk on this subject at AngularConnect. You can watch that talk here if you are interested in learning more about. It’s worth watching!

What is Transloco?

Transloco is a library developed and maintained by the NgNeat team. It contains a multitude of features and officially supported plugins to help make translating your Angular applications easy, maintainable, scalable and performant. It is actively maintained and it supports:

• Lazy loading
• Multiple fallbacks
• Server-side rendering
• Localization (l10n)
• Runtime language changing
• Multiple languages simultaneously
• Pluralization (through an official plugin)

It’s very easy to set up and use as we’ll see in the next part of this post!

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.

Basics of Angular: Part-1

What is Angular? What it does? How we implement it in a project? So, here are some basics of angular to let you learn more about angular.

Angular is a Typescript-based open-source front-end web application platform. The Angular Team at Google and a community of individuals and corporations lead it. Angular lets you extend HTML’s syntax to express your apps’ components clearly. The angular resolves challenges while developing a single page and cross-platform applications. So, here the meaning of the single-page applications in angular is that the index.html file serves the app. And, the index.html file links other files to it.

We build angular applications with basic concepts which are NgModules. It provides a compilation context for components. At the beginning of an angular project, the command-line interface provides a built-in component which is the root component. But, NgModule can add a number of additional components. These can be created through a template or loaded from a router. This is what a compilation context about.

What is a Component in Angular?

Components are key features in Angular. It controls a patch of the screen called a view. A couple of components that we create on our own helps to build a whole application. In the end, the root component or the app component holds our entire application. The component has its business logic that it does to support the view inside the class. The class interacts with the view through an API of properties and methods. All the components added by us in the application are not linked to the index.html. But, they link to the app.component.html through the selectors. A component can be a component and not only a typescript class by adding a decorator @Component. Then, for further access, a class can import it. The decorator contains some metadata like selector, template, and style. Here’s an example of how a component decorator looks like:

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.scss']
})

Role of App Module

Modules are the package of functionalities of our app. It gives Angular the information about which features does my app has and what feature it uses. It is an empty Typescript class, but we transform it by adding a decorator @NgModule. So, we have four properties that we set up on the object pass to @NgModule. The four properties are declarations, imports, providers, and bootstrap. All the built-in new components add up to the declarations array in @NgModule.

@NgModule({
declarations: [
  AppComponent,
],
imports: [
  BrowserModule,
  HttpClientModule,
  AppRoutingModule,
  FormsModule
],
bootstrap: [AppComponent]
})

What is Data Binding?

Data Binding is the communication between the Typescript code of the component and the template. So, we have different kinds of data binding given below:

• When there is a requirement to output data from our Typescript code in the HTML template. String interpolation handles this purpose like {{data}} in HTML file. Property Binding is also used for this purpose like [property] = “data”.
• When we want to trigger any event like clicking a button. Event Binding works while we react to user events like (event) = “expression”.
• When we can react to user events and output something at the same time. Two-way Binding is used like [(ngModel)] = “data”.

Why Choose AngularJS framework for the enterprise? | Angular development Company - CMARIX

Although Angular JS has bought headlines over the domain of Web application development, its relevance downtime does not offer any guarantee. Since the JavaScript application is the child of Google, its web features may have some value. Angular JS enables the developer to write most of the code in HTML which brings the application together. Such potentiality and simplicity of the program from the Angular Development Company made Angular popular among JavaScripts.

But the real question arises on the integrity and the safety Angular can provide to the industry. Angular regularly updates its libraries to fix security issues over earlier versions. However, the private and customized Angular versions fall back from the latest versions. These versions might lack the crucial security patches. As a piece of advice, developers can share their improvement requests in the community.

Backward compatibility indicates that the updated versions can function with the outdated versions. Hence, it can simplify the migration procedures to the latest Angular version. Some portions of the AngularJS apps need lazy loading to ease the update and to facilitate the transfer of large projects.

Since AngularJS tends to spoil backward compatibility, it might cause future problems in a program.

The Changing Face of Frameworks

There were several ups and downs in the Web application market over the past. A few years ago, SproutCore ruled the throne as a top framework. However, according to Google search trends, BackboneJS later stole the spotlight which again passed over to EmberJS. But, there remains no comparison for AngularJS.

Birthed by Adam Abrons and Misko Hevery, the Brat Tech engineers in 2009, the Angular Development Company AngularJS took a swift transition to open-source. When Misko Hevery joined Google, he continued to develop Angular JS. The platform began to earn its place by December of 2012 according to Google Trends.

In the year 2015, the potential of AngularJS surpassed other frameworks and offered job placements for many developers. However, AngularJS is not entirely without competition as Facebook came up with ReactJS. Hence, there is a race to show which surpasses the other. But, according to Jeff Schroeder, among the native apps, React elevates mobile app development to higher levels.

Continuous Development in Angular JS

AngularJS has high popularity yet, the developers break backward compatibility on a regular basis. Therefore, the supporters of AngularJS have to learn the AngularJS framework again and again. A critic of AngularJS – Danny Tuppeny, points out that the framework is unstable as it offers short-term support. The developers develop the framework every now and then which can puzzle its users. However, a mobile Web developer by the name of Nene Bodonkor indicates another factor. The frameworks become satisfactory and since they fail to keep up with the market requirements, change becomes crucial.

On the contrary, Yehuda Katz, the creator of EmberJS suggests that the fast-paced lifestyle needs to slow down. Therefore, these constant changes can compel people to reduce and balance their pace. Both, ReactJS from Facebook and EmberJS fight to achieve maximum backward compatibility. Such a characteristic helps these frameworks to come to use for an enterprise. But, AngularJS still has its upper hand over its competitors.

The simple-to-learn design of the Angular Framework with various functions

A legacy system includes few characteristics like old technology that are not compatible with the present systems. These systems do not remain available for purchase from distributors or vendors. These legacy systems cannot update nor patch up by themselves as the developer or vendor stops its maintenance.

The CTO of a mobile and Web app development company Monsoon, Michi Kono agreed on the decisions. But he also commented that the core developers at AngularJS miscommunicated the information. As the AngularJS framework has its uses in Google, they can use the platform for legacy versions and supporting enterprises. According to Michi Kono, AngularJS can promise a safe approach for its use in enterprises. The framework of Angular Development Company USA makes learning simple as it lacks strong convention opinions. The framework is easy for developers to learn and Angular has its applications on other parallel technologies. Vast organizations that have a demand for on-scale development and hiring procedures can use the framework to their advantage.

The low level of Angular appears more as a toolbox than a framework. Such an approach makes Angular useful on a wide variety of utility functions. The developer can use the JavaScript framework to add a single website button through a separate framework. Major companies like Google, Facebook and Microsoft aim to improve JavaScript to match entrepreneur requirements. Since AtScript or the typed JavaScript from Google, will form the backbone of AngularJS 2.0, several developers shall prefer to leverage it.

The Best Fit

AngularJS has several promising aspects for developers from different enterprises to try. But the JavaScript framework undergoes several alterations by its developers. Yet, some of the JavaScript frameworks grab the focus of various users for which they remain in maintenance. Therefore, according to Brian Leroux, the Adobe Web developer, there are two options left. Developers can either imprison themselves within vast rewrites with no forward progress. Or Hire angular developers who can focus their attention to optimize the website architecture. Therefore, developers need to stay up-to-date with the current developments in the web application frameworks like AngularJS.

AngularJS frameworks carry lots of potential in real-time markets. But, the developers need to stay up-to-date to tackle the regular changes in its infrastructure.
