New way of debugging template syntax errors with ng-template-error

Debugging template syntax errors in Angular can be a frustrating experience, but the new tool ng-template-error makes the process much easier and more efficient. This tool helps developers identify and debug errors in their Angular templates by providing a detailed error message with the exact location of the error in the template file.

In Angular, templates are used to define the structure and layout of the user interface. When there is an error in the template syntax, the application will not work as expected. For example, if there is a typo in a property name or if the property doesn't exist, Angular will throw an error. These types of errors can be difficult to locate and fix without proper tools.

The ng-template-error tool solves this problem by providing a clear error message that makes it easy to identify the source of the error. Let's look at an example to see how it works.

<ng-template #myTmpl>
   {{this.willThrowError}}
</ng-template>
Enter fullscreen mode Exit fullscreen mode

In this example, we have a simple ng-template that tries to bind the property willThrowError. If we run this code, Angular will throw an error because the property willThrowError doesn't exist. With ng-template-error, we will see the following error message:

Template parse errors:
Can't bind to 'willThrowError' since it isn't a known property of '<ng-template>'.
Enter fullscreen mode Exit fullscreen mode

This error message clearly indicates that there is an error in the template and that the property willThrowError is not a known property of the ng-template. The error message also specifies the exact location of the error in the template file, making it easy to identify and fix the issue.

Another advantage of ng-template-error is that it makes it easier to debug complex templates. With large templates, it can be challenging to locate the source of an error. However, with ng-template-error, the error message will be displayed with the exact location of the error, even in complex templates.

In conclusion, ng-template-error is a powerful tool for Angular developers looking to streamline their debugging process and improve the efficiency of their workflow. With its clear error messages and precise location of errors, ng-template-error makes it easy to quickly identify and resolve template syntax errors in Angular applications.
