Angular Training Overview
Angular allows developers to easily build dynamic, responsive single-page web applications that dynamically rewrite portions of the current page rather than having to generate a new page in response to every request.
Accelebrate's Angular training teaches attendees how to build applications using ES6, TypeScript, and modern front-end tools, including npm and Webpack. Students also gain an understanding of application architecture and design best practices in Angular, as well as learn how to authenticate, unit test, and manage application state in an Angular application.
Note: This course is taught in the current version of Angular at the time of teaching.
Location and Pricing
Accelebrate offers instructor-led enterprise training for groups of 3 or more online or at your site. Most Accelebrate classes can be flexibly scheduled for your group, including delivery in half-day segments across a week or set of weeks. To receive a customized proposal and price quote for private corporate training on-site or online, please contact us.
In addition, some courses are available as live, instructor-led training from one of our partners.
Objectives
- Understand how single-page web application architectures are different than traditional web application architectures
- Use new JavaScript (ES6) language features including Classes, Modules, and Arrow Functions
- Use new TypeScript language features including Types, Decorators, Interfaces, and Generics
- Learn Angular coding and architecture best practices including project layout and using container and presentation components
- Understand and use Angular model-driven forms, observables, dependency injection, and routing
- Communicate with a backend server using Angular’s HttpClient to load and save data
- Configure the router and navigate between components
- Unit test all parts of an application including Components, Services, and Pipes
- Implement Authentication and Authorization in an Angular Application
- Optimize Angular Performance by changing Change Detection Strategies
- Setup new projects from scratch using the Angular CLI
- Scaffold modules, components, services, models, routes, and unit tests in accordance with best practices using the Angular CLI
- Write End-to-End Tests (optional; taught only if this applies to your group)
- Upgrade an existing application from AngularJS to the current Angular version (optional; taught only if this applies to your group)
Prerequisites
Students must have object-oriented programming experience. Some experience with JavaScript is helpful; the new language features of JavaScript and TypeScript are covered/reviewed in class.
