Angular 2 is a vast and complex framework with a never ending learning curve. To help you grasp more of its many features, we’ve curated a list of 30 free learning resources that cover it all – from the quickstart guide to specific details and best practices.
Let’s first quickly go over the available guides and tutorials on the official Angular website. There are a bunch of different resources there and we decided it’s a good idea to explain them.
This will be the starting point for most beginners to Angular2. It includes setting up a work environment and running a basic Hello World app. Don’t be fooled by its name, you will need a good hour or two to finish this QuickStart.
Tour of heroes is a much more detailed tutorial than the QuickStart. It goes through the process of building a Single Page App, step by step, covering many of the must-know Angular2 features. There are TypeScript and Dart versions, but no vanilla JS.
Here the Angular team offers over 15 standalone tutorials, each doing a very in-depth look into an important topic. You can learn about Angular animations, the lifecycle of components, the navigation router, and many other core features.
A collection of code snippets and quick solutions to common challenges. Here you can find a chart of the differences between Angular 1 and 2, a FAQ section on NgModules, and solutions for form validation among other helpful tips and guides.
Now let’s look at some tutorials and articles written by the community. We’ve tried to include only publications that are fairly new, making them compatible with the changes in recent versions.
A well-written article that covers everything you need to know about upgrading old Angular 1 apps to the new framework. In it you can see what Angular2 does better, which aspects of an app need the most radical changes, as well as practical code snippets to get the job done.
This tutorial focuses on the new 3.0 router component, and explains the whole process needed for configuring it correctly. The author has done a great job explaining what Single Page Apps are, how they work, and how to route them in a robust and secure way.
A more beginner-oriented lesson looking at different techniques for adding CSS styles to components. It shows you how to use component inline styles, style urls, and template inline styles, and explains the advantages behind each one.
Angular apps tend to get really big, and at some point the source files become too large to be loaded at once. Lazy loading allows us to speed up application load time by splitting it into multiple bundles, and loading them on demand.
A deep dive into the greatly improved Angular2 dependency injection system and the different approaches behind the old and new DI. This article also has a second part, that further explains the host-child relationship and the visibility of dependencies.
The Angular2 change detection mechanism is much more transparent and easier to reason about than its equivalent in Angular 1. However, there are still situations where you need to know exactly whats going on under hood.
Angular is a very powerful and complex framework, and it’s not surprising that it’s footprint is also quite large. In this blog post you can learn various techniques, such as Tree-shaking and minification, that will drastically reduce the size of your final app.
Observables in Angular 2 can be used for handling asynch code as an alternative to Promises. They are a vast and complex topic, but this two-part tutorial does a great job of introducing them and showcasing their many use cases.
An interesting take on design patterns for building Angular components. The article goes through the components of a YouTube music player app and the relationships between them, with lots of code examples and explanations.
NgUpgrade is meant to bridge the gap between Angular 1 and 2 by allowing code from both frameworks to co-exist in the same app. This can greatly increase the size as both versions need to be included. You can learn how to reduce that extra footprint in this quick tip.
In this article you will learn three different techniques that you can use to thoroughly test Angular 2 components. They are isolated testing, shallow testing, and integration testing. All three have their strengths and weaknesses and are best applied in certain scenarios.
Protecting routes is a very common task when building applications, as we want to prevent our users from accessing areas that they’re not allowed to access. Angular 2’s router provides a feature called Guards that tries to solve exactly that problem.
This guide gives a comprehensive overview of the various ways you can debug an Angular 2 applications using tools such as the Chrome DevTools, Angular Augury, simple JSON pipe filters, and the console itself.
Since we know many developers prefer interactive lessons, here are a couple of places where you can find excellent code walkthroughs and general Angular talks.
Egghead.io is one of the most popular and recommended sources for learning Angular. Although many of the lessons are for pro members only, there are still lots and lots of awesome free lessons you can watch.
Adventures in Angular is a weekly podcast dedicated to the Angular framework. The panel cover a wide array of topics and it’s probably the best place to get Angular news. The archive contains over 110 episodes, each at least 30 minutes long.
Awesome one-hour-long course covering most of the basics. Although its beginner-oriented there are lots of things everyone can learn from this video in therms of project management and workflow.
A YouTube channel with lots of screencasts on web development and programming, with a focus on Angular 2 and its ecosystem of related technologies, tools, and languages.
Another YouTube channel with a large collection of Angular tutorials, courses, code examples, and quick-tips.
Last but not least, here are some resources that didn’t fit any of the above categories, but can still be essential learning tools for any Angular developer.
The only completely free book on Angular 2 that we could find. It covers the most important Angular 2 topics, from getting started with the basic toolchain, to writing applications in a scalable and maintainable manner. You can read it in the web browser or download it as an eBook (PDF, Mobi, ePub).
The offical style guide for the framework. Contains a ton of syntax and formatting recommendations, as well as general best practices. It’s very detailed and long, but knowing Angular’s enterprise nature, you’ll probably need to go through it at some point.
Learn from other people’s experiences with the framework by checking out this large collection of open-source applications and experiments, all developed in Angular 2.
An interview and Q&A with the creators of the framework, right after the release of Angular 2 Final. A great place to hear more about the project and its upcoming features straight from the horses mouth.
