Improve app performance with Angular 17 defer 🤩

In recent years, Angular has become a popular framework for building dynamic web applications. With the release of Angular 17, developers now have access to the defer attribute, which can help improve app performance.

What is the defer attribute?

The defer attribute is a new feature in Angular 17 that allows developers to postpone the execution of certain scripts until the HTML document has been fully parsed. This can be particularly useful for improving performance, as it allows the rest of the page to load without being delayed by script execution.

How to use the defer attribute

Using the defer attribute in Angular 17 is simple. Developers can simply add the attribute to their script tags, like so:

<script defer src="app.js"></script>
<script defer src="controller.js"></script>

By adding the defer attribute to their script tags, developers can ensure that their scripts will be executed after the HTML document has been fully parsed, improving overall app performance.

Benefits of using the defer attribute

There are several benefits to using the defer attribute in Angular 17. By postponing the execution of certain scripts, developers can improve app performance by allowing the rest of the page to load without being blocked by script execution. This can lead to faster page load times and an overall smoother user experience.

Conclusion

With the release of Angular 17, developers now have access to the defer attribute, which can help improve app performance by postponing the execution of certain scripts. By using the defer attribute, developers can ensure that their scripts are executed after the HTML document has been fully parsed, leading to faster page load times and an overall smoother user experience.
