Useful command of Angular CLI

I made a small list of commands which use a lot in Angular CLI and I want to share my list with you.

First of all, we need to install Angular CLI.

npm install -g @angular/cli

This command we need to write in terminal or console.

When cli is installed we need to create our first project:

ng new name-of-project

This command will create an empty project for us. If want to use in our project SCSS files instead of CSS,we must write:

ng new name-of-project --style=scss

After project creation, we need to install all packages which contains in packege.json.

npm intall

Now packages are installed and we can run our project:

ng serve

If we want to run and open our project in browser we should use:

ng serve --open 

By default Angular run project on port:4200, if we want to set another port:

ng serve --port=4222

Also we can use both those option in one command:

ng serve --open --port=4222 

Setting the watch option false will stop automatic rebuilds when you change code:

ng serve --watch=false

When running ng serve, the compiled output is served from memory, not from disk. This means that the application being served is not located on disk in the dist folder.

ng serve --poll 1000

Sometimes could be very useful to build project in production mode:

ng build --prod

Also we could use Ahead of Time Compilation which compiles your app at build time:

ng build --prod --aot

It is time to start developing our project, that means we need to create a new component, class, module, or something else. Angular CLI can help us with that:

ng generate component name-of-component

#angular-cli #angular #cli #front-end-development

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
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

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.

Angular Sass: How To Use Sass In Angular 9 Tutorial

Angular supports Sass, CSS, and Less to style global application styles as well as component styles. Angular components styles have an effective CSS encapsulation mechanism that assures any component CSS is local to the component and does not globally alter any styles.

Angular Sass Example

Why use Angular Sass? Well!! Sass (Syntactically Awesome Style Sheets) is an extension of CSS that allows you to use things like variables, nested rules, inline imports, and more. It also supports you to keep things organized and enables you to create style sheets faster.

In short,  Sass is a CSS preprocessor, which combines unique features such as variables, nested rules, and mixins (sometimes referred to as syntactic sugar) into regular CSS. The main object of Sass is to make the CSS coding process more comfortable and more efficient.

Sass is compatible with all versions of CSS. When working with the Angular CLI, the default stylesheets have the .css extension. We are using Angular CLI 8. So, if you have not used previously, then please upgrade your  CLI version. We will use the Bootstrap 4 Framework for this demo and see how we can configure the Sass in our Angular 9 application.

Tutorial: Nx-style monorepo workspace with Angular CLI: Part 3

In Part 3 of this tutorial, we create the passenger info and flight search feature libraries. We use the generate project tool to create the mobile booking application and its test project. Finally, we create a mobile version of the flight search component template.

This tutorial is part of the Angular Architectural Patterns series.

In Part 2 of this tutorial, we used the generate project tool to generate the booking data access and shared data access workspace libraries with NgRx Store and Effects. We extracted a shared environments library and hooked everything up to the booking feature shell library.

In this part of the tutorial, we’re going to create the passenger info and flight search feature libraries, each with a routed component. After that, we’ll create the mobile booking application project and its end-to-end test project. Finally, we’ll use builder file replacement to create a mobile version of the flight search component template.

THIS AD MAKES CONTENT FREE. HIDE

Passenger info feature library#

Let’s create our first feature library, the passenger info feature which is part of the booking domain.

npm run generate-project -- library feature feature-passenger-info --scope=booking --npm-scope=nrwl-airlines
# or
yarn generate-project library feature feature-passenger-info --scope=booking --npm-scope=nrwl-airlines
<>

Generate passenger info feature library.

After generating the project using the previous commands and parameters, we get this file and folder structure.

libs/booking/feature-passenger-info
├── src
│   ├── lib
│   │   ├── passenger-info
│   │   │   ├── passenger-info.component.css
│   │   │   ├── passenger-info.component.html
│   │   │   ├── passenger-info.component.spec.ts
│   │   │   └── passenger-info.component.ts
│   │   ├── booking-feature-passenger-info.module.spec.ts
│   │   └── booking-feature-passenger-info.module.ts
│   ├── index.ts
│   └── test.ts
├── README.md
├── karma.conf.js
├── tsconfig.lib.json
├── tsconfig.spec.json
└── tslint.json
<>

The file and folder structure of the booking passenger info feature library.

This looks a little different from a feature shell library and a data access library.

After the generate project tool has created the workspace library with an entry point Angular module, it runs the commands in the next listing.

The generate project tool also removed the --no-common-module flag from the ng generate module command we saw earlier, since this Angular module will be declaring components.

ng generate component passenger-info --project=booking-feature-passenger-info --module=booking-feature-passenger-info.module.ts --display-block
<>

Generate component command run when generating a feature library.

Let’s look at the Angular module our tool has generated.

// booking-feature-passenger-info.module.ts
import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';

import {
  PassengerInfoComponent,
} from './passenger-info/passenger-info.component';

@NgModule({
  declarations: [PassengerInfoComponent],
  imports: [
    CommonModule,
  ],
})
export class BookingFeaturePassengerInfoModule {}
<>

Initial entry point Angular module in the passenger info feature library.

The entry point Angular module shown in the previous listing is a good starting point. We need to set up the feature routing for our component though. This is done in the next listing.

// booking-feature-passenger-info.module.ts
import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

import {
  PassengerInfoComponent,
} from './passenger-info/passenger-info.component';

const routes: Routes = [
  {
    path: '',
    pathMatch: 'full',
    component: PassengerInfoComponent,
  },
];

@NgModule({
  declarations: [PassengerInfoComponent],
  imports: [
    RouterModule.forChild(routes),
    CommonModule,
  ],
})
export class BookingFeaturePassengerInfoModule {}
<>

Passenger info feature Angular module with route configuration for its entry point component.

Nice! Now we’ve prepared our feature library to be hooked up to the feature shell library’s routing configuration.

The generated component is what you’d expect. What it’d display in a real booking application is not really important for the purpose of this article.

Let’s hook up this feature to the booking application’s routing by adding a route configuration to the booking feature shell Angular module as seen here.
