Angular

Install the latest version of Angular

With node.js and npm installed, the next step is to install the Angular CLI which provides tooling for effective Angular development.

From a Terminal window run the following command: npm install -g @angular/cli

 Project Setup and Generation

  ng generate <schematic>              Run the provided schematic.                                                                                                                                   [default]

  ng generate ai-config                Generates AI configuration files for Angular projects. This schematic creates configuration files that help AI tools follow Angular best practices, improving the

                                       quality of AI-generated code and suggestions.

  ng generate app-shell                Configures your project to generate an app-shell during build time.

  ng generate application [name]       Generates a new Angular application within your workspace. This schematic sets up the foundational structure of your project, including the root component, module, and

                                       configuration files. You can customize various aspects of the application, such as routing, styling, and testing.                                        [aliases: app]

  ng generate class [name]             Creates a new class in your project. Classes are the fundamental building blocks for object-oriented programming in TypeScript. They provide a blueprint for creating

                                       objects with properties and methods. This schematic helps you generate a new class with the basic structure and optional test files.                      [aliases: cl]

  ng generate component [name]         Creates a new Angular component. Components are the basic building blocks of Angular applications. Each component consists of a TypeScript class, an HTML template, and

                                       an optional CSS stylesheet. Use this schematic to generate a new component in your project.                                                                [aliases: c]

  ng generate config [type]            Generates configuration files for your project. These files control various aspects of your project's build process, testing, and browser compatibility. This schematic

                                       helps you create or update essential configuration files with ease.

  ng generate directive [name]         Creates a new directive in your project. Directives are used to extend the behavior or appearance of HTML elements and components. They allow you to manipulate the

                                       DOM, add custom attributes, and respond to events. This schematic generates the necessary files and boilerplate code for a new directive.                  [aliases: d]

  ng generate enum [name]              Creates a new enum in your project. Enums (enumerations) are a way to define a set of named constants, making your code more readable and maintainable. This schematic

                                       generates a new enum with the specified name and type.                                                                                                     [aliases: e]

  ng generate environments             Generates and configures environment files for your project. Environment files allow you to define different settings and configurations for various environments, such

                                       as development, testing, and production. This schematic helps you create and manage these files, making it easier to customize your application's behavior for each

                                       environment.

  ng generate guard [name]             Creates a new route guard in your project. Route guards are used to control access to parts of your application by checking certain conditions before a route is

                                       activated. This schematic generates a new guard with the specified name, type, and options.                                                                [aliases: g]

  ng generate interceptor [name]       Creates a new interceptor in your project. Interceptors are used to intercept and modify HTTP requests and responses before they reach their destination. This allows

                                       you to perform tasks like adding authentication headers, handling errors, or logging requests. This schematic generates the necessary files and boilerplate code for a

                                       new interceptor.

  ng generate interface [name] [type]  Creates a new interface in your project. Interfaces define the structure of objects in TypeScript, ensuring type safety and code clarity. This schematic generates a

                                       new interface with the specified name and type.                                                                                                            [aliases: i]

  ng generate library [name]           Creates a new library project in your Angular workspace. Libraries are reusable collections of components, services, and other Angular artifacts that can be shared

                                       across multiple applications. This schematic simplifies the process of generating a new library with the necessary files and configurations.             [aliases: lib]

  ng generate module [name]            Creates a new, generic NgModule definition in the given project.                                                                                           [aliases: m]

  ng generate pipe [name]              Creates a new pipe in your project. Pipes are used to transform data for display in templates. They take input values and apply a specific transformation, such as

                                       formatting dates, currency, or filtering arrays. This schematic generates the necessary files and boilerplate code for a new pipe.                         [aliases: p]

  ng generate resolver [name]          Creates a new resolver in your project. Resolvers are used to pre-fetch data before a route is activated, ensuring that the necessary data is available before the

                                       component is displayed. This can improve the user experience by preventing delays and loading states. This schematic generates a new resolver with the specified name

                                       and options.                                                                                                                                               [aliases: r]

  ng generate service [name]           Creates a new service in your project. Services are used to encapsulate reusable logic, such as data access, API calls, or utility functions. This schematic simplifies

                                       the process of generating a new service with the necessary files and boilerplate code.                                                                     [aliases: s]

  ng generate service-worker           Adds a service worker to your project. Service workers enable your application to work offline or on low-quality networks by caching assets and intercepting network

                                       requests. This schematic configures your project to use a service worker.

  ng generate web-worker [name]        Creates a new web worker in your project. Web workers allow you to run JavaScript code in the background, improving the performance and responsiveness of your

                                       application by offloading computationally intensive tasks. This schematic generates the necessary files for a new web worker and provides an optional code snippet to

                                       demonstrate its usage.
