Introduction to The Different Types of Angular CLI Commands

In this article, we are going to learn what the different types of Angular CLI commands are, and the tools that power them. Let's get started.

There are three types of Angular CLI commands:

  • schematics commands:ng add,ng generate,ng new,ng update;
  • architect commands:ng build, ng deploy, ng e2e,ng lint,ng run,ng serve,ng test,ng xi18n;
  • and native commands:ng config,ng doc,ng version, ng analytics, ng help.

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.

The Different Types of Angular CLI Commands

In this article, we are going to learn what the different types of Angular CLI commands are, and the tools that power them. Let’s get started.

There are three types of Angular CLI commands:

  • schematics commands:ng add,ng generate,ng new,ng update;
  • architect commands:ng buildng deployng e2e,ng lint,ng run,ng serve,ng test,ng xi18n;
  • and native commands:ng config,ng doc,ng versionng analyticsng help.

Schematics commands

Schematics commands are based on a tool called Schematics that comes from the @angular-devkit/schematics package. Schematics is the underlying tool the Angular CLI uses to scaffold a new Angular workspace (ng new), generate blueprints (ng generate), update/migrate existing code (ng update), and add some frameworks support to an Angular application (ng add). It’s all about code generation.

The nice thing about Schematics is that it allows us to extend the CLI’s scaffolding capabilities.

Learn how Air France-KLM is leveraging schematics in another blog post– The Angular CLI at Air France-KLM.

Architect commands

Architect commands are based on a tool called Architect that is published under the @angular-devkit/architect package name. Architect helps the Angular CLI lint (ng lint), test (ng testng e2e), serve (ng serve), build (ng build), and deploy (ng deploy) our Angular applications. It’s all about running complex tasks.

With the Architect tool, we can now create custom tasks for the Angular CLI. Previously, one would eject the Webpack configuration of the Angular CLI–using the now deprecated ng eject command–to be able to tweak the build process. Now every customization can be done using Architect. That’s why, the ng eject command was removed in Angular CLI v8.

Native commands

Native commands are general Angular CLI commands. They are native to the Angular CLI in the sense that they don’t rely on other tools/packages to be executed. Displaying our packages’ versions (ng version), opening the official documentation (ng doc), reading and setting some values in the angular.json file (ng config), or displaying the list of available commands and their description (ng help) do not require the use of any specific tool.

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

Tutorial: Nx-style monorepo workspace with Angular CLI: Part 5

In the final part of this tutorial, we create the seatmap data access, seat listing feature, shared buttons UI, and shared formatting utilities library. Finally, we compare our approach with the full Nx toolchain.

This tutorial is part of the Angular Architectural Patterns series.

In Part 4 of this tutorial, we used our generate project tool to create the check-in data access library, the check-in feature shell library, the check-in desktop application, and the mobile check-in application. We hooked everything up and reviewed how much was automated by our tool.

In this part of the tutorial, we’re going to create the seatmap data access library with NgRx feature state. We then created the seat listing feature library and hooked it up to all applications with routing. Finally, we created the shared buttons UI library and the shared formatting utilities library which we used in the seat listing component.

THIS AD MAKES CONTENT FREE. HIDE

Seatmap data access library#

The shared seatmap feature has its own data access library. This is where we would add data services and application state management specific to the seatmap domain.

npm run generate-project -- library data-access --scope=seatmap --grouping-folder=shared/seatmap --npm-scope=nrwl-airlines --with-state
# or
yarn generate-project library data-access --scope=seatmap --grouping-folder=shared/seatmap --npm-scope=nrwl-airlines --with-state
<>

Generate the seatmap data access library.

For now, we’ll put the feature store and effects in place by using the --with-stateparameter of the generate project tool. Note that we use the nested grouping folder shared/seatmap.

// seatmap-data-access.module.ts
import { NgModule } from '@angular/core';
import { EffectsModule } from '@ngrx/effects';
import { StoreModule } from '@ngrx/store';

import { SeatmapEffects } from './+state/seatmap.effects';
import * as fromSeatmap from './+state/seatmap.reducer';

@NgModule({
  imports: [
    StoreModule.forFeature(fromSeatmap.seatmapFeatureKey, fromSeatmap.reducer),
    EffectsModule.forFeature([SeatmapEffects]),
  ],
})
export class SeatmapDataAccessModule {}
<>

The seatmap data access module.

The seatmap data access Angular module gives us an overview of what’s configured in the seatmap data access library. This is a good starting point.

ng run seatmap-data-access:lint

ng run seatmap-data-access:test --watch=false
<>

Lint and test the seatmap data access library.

Everything looks ready to go!

Seat listing feature library#

It’s time to add the first feature of the seatmap domain which is used in both the check-in and booking applications.

npm run generate-project -- library feature feature-seat-listing --scope=seatmap --grouping-folder=shared/seatmap --npm-scope=nrwl-airlines
# or
yarn generate-project library feature feature-seat-listing --scope=seatmap --grouping-folder=shared/seatmap --npm-scope=nrwl-airlines
<>

Generate the seatmap seat listing feature library.

Our tool generates an Angular module and a component for us.

To add this feature to our applications, we add a route to each feature shell module.

// check-in-feature-shell.module.ts
import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { CheckInDataAccessModule } from '@nrwl-airlines/check-in/data-access';
import { SharedDataAccessModule } from '@nrwl-airlines/shared/data-access';

import { ShellComponent } from './shell/shell.component';

const routes: Routes = [
  {
    path: '',
    component: ShellComponent,
    children: [
      {
        path: '',
        pathMatch: 'full',
        redirectTo: 'seatmap', // 👈
      },
      {
        path: 'seatmap', // 👈
        loadChildren: () =>
          import('@nrwl-airlines/seatmap/feature-seat-listing')
            .then(esModule => esModule.SeatmapFeatureSeatListingModule),
      },
    ],
  },
];

@NgModule({
  declarations: [ShellComponent],
  exports: [RouterModule],
  imports: [
    RouterModule.forRoot(routes),
    SharedDataAccessModule,
    CheckInDataAccessModule,
    CommonModule,
  ],
})
export class CheckInFeatureShellModule {}
