Fixing angular2-highcharts Compatibility Issues in Angular 11

If you're an Angular developer delving into charting libraries, you might have come across a roadblock while trying to use angular2-highcharts with Angular 11. Many developers, including myself, experienced issues after upgrading from an earlier version like Angular 8. In this blog, we'll explore why these problems arise and what you can do to resolve them effectively.

The Problem: Compatibility Issues with Angular 11

When working with angular2-highcharts, you may find that it functions seamlessly with Angular 8, but suddenly stops working after an upgrade to Angular 11. This discrepancy mainly stems from a significant change in Angular’s architecture – the introduction of the Ivy compiler. In essence, angular2-highcharts was built for the older "View Engine," while Angular 11 utilizes the new Ivy compiler. This incompatibility is primarily the root cause of your issues.

Common Symptoms

You might notice issues such as:

Charts not rendering

Runtime errors related to module imports

Performance problems as the framework tries to adapt incompatible code

The Solution: Transitioning to highcharts-angular

Fortunately, there is a straightforward solution to this problem. The recommended approach is to transition from angular2-highcharts to the official highcharts-angular wrapper. This library is actively maintained and fully compatible with Angular's Ivy compiler. Here’s how to make the switch:

Step-by-Step Guide

Install the Official Wrapper:
First, you need to install highcharts-angular. You can do this using npm:

Conclusion

Upgrading to Angular 11 does require re-evaluating your dependencies, especially for libraries like angular2-highcharts, which are no longer compatible with newer compiler architecture. By switching to highcharts-angular, you not only gain compatibility but also access to a library that is well-reviewed and frequently updated.

Making such changes may seem daunting at first, but following the steps outlined above should help you migrate smoothly and get your charting needs back on track in no time. Happy coding!
