Lazy Loading Locales with Angular - ANGULARarchitects

Angular 9 introduces a new implementation for its built-in I18N support called @angular/localize. One concept it contains is called global locales. These are bundles with meta data for different date and number formats the CLI can add after compiling the application.

Normally, the CLI uses these bundles under the hood to dramatically speed up the creation of different language versions. However, we can divert it from its intended use to load the meta data dynamically on demand.

This article shows how to leverage this. The used example can be found in my GitHub repo.

Big thanks to Angular’s Pete Bacon Darwin who helped me to see the whole picture regarding global locals.

Situation Before Angular 9

Beginning with Angular 5, Angular is shipped with meta data for different locales. It is derived from the Unicode Common Locale Data Repository (CLDR). To support some of them, we had to import and register them before the application starts, e. g. within main.ts:

import { registerLocaleData } from '@angular/common';
import localeDe from '@angular/common/locales/de';
import localeDeAt from '@angular/common/locales/de-AT';
import localeEs from '@angular/common/locales/es';

registerLocaleData(localeDe);     // de-DE
registerLocaleData(localeDeAt);   // de-AT
registerLocaleData(localeEs);     // es-ES


  .catch(err => console.error(err));

In addition to these locales, en-US is always available.

Obviously, this increases the size of the main bundle as all this meta data is referenced at compile time. As the next chapters show, Angular 9 introduces a way to prevent this situation.

Global Locales

Beginning with version 9, Angular is also providing a special set of bundles registering the locale meta data globally at For instance, in the case of German, the meta data would be put to['de']. Hence, they are called global locales.

These bundles are located within node_modules/@angular/common/locales/global:

global locales

Global Locals go hand in hand with the new @angular/localize package which brings the built-in I18N support to the next level. The idea of this package is to only compile the application once. Then, this compiled version is duplicated for each language one wants to support and each of these duplications is modified.

These modifications involve exchanging texts but also adding the right meta data. For the latter one, we need a way to simply add this meta data after the build. This is what global locals enable.

Obviously, this approach is much faster than the original one which compiled the whole application once per language.

Saying this, normally you don’t need to deal directly with these global locals because the CLI does the heavy lifting for you. If you want to try it out, you find a wonderful blog post about [@angular/localize]( here.

However, if you don’t use @angular/localize do deal with translation texts but go with something like ngx-translate instead, directly dealing with global locales will come in handy. This is also the case if you do use @angular/localize but define the translation texts programatically, e. g. after loading them from a custom service in a custom data format (which is called runtime tranlation).

In these cases, loading just the needed meta data on demand instead of loading the meta data for all languages upfront will improve your startup performance.

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!!!

Angular environment setup

Install Angular in Easy Steps

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

  • Node.js
  • npm Package Manager

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

installing 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

create angular workspace

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

angular CSS options

  • 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:

    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.

declarations: [
imports: [
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”.
