Description

Introduction of Angular Libraries and Modules

Creating custom Angular libraries and modules allows developers to reuse code, improve maintainability, and enhance modularity across Angular applications. This training covers the best practices for building, packaging, and publishing custom Angular libraries, along with techniques for optimizing module design and dependency management.

Prerequisites

• Basic knowledge of Angular and TypeScript
• Experience with Angular Components, Services, and Directives
• Familiarity with Angular CLI and npm packages
• Understanding of Angular Modules (NgModule) and Dependency Injection
