Fixing the ngx-spinner Type Error: A Comprehensive Guide

When working on Angular applications, you might come across an error that states: "[ngx-spinner]: Property 'type' is missed." This error can be frustrating, especially when you're trying to implement a loading spinner for better user experience. In this guide, we'll dive into what this error means, and how to resolve it step by step.

Understanding the Problem

The error you're encountering typically indicates that the spinner type has not been defined in the configuration. The ngx-spinner library provides various types of loading indicators to choose from, but failing to specify the type will result in this error. Here's a brief overview of the components involved:

Busy Service: This is a service that manages the visibility of the spinner.

Angular Configuration: The styles and animations for the spinner need to be properly defined in the angular.json file.

When the type is not specified, your spinner won't load as intended, which could lead to a confusing experience for users.

Step-by-Step Solution

To fix the error, you'll need to follow the steps we outlined below. Let's break it down:

1. Edit Your Busy Service

Ensure your busy service is correctly configured to show the spinner with a defined type. Here’s how your busy method should look:

3. Selecting Your Loader Animation Type

In the code above, we've included the line scale party animation as an example of a spinner type. You can find other animations available in the node_modules/ngx-spinner/animations directory. Choose one that fits your application and insert it into the angular.json file.

Conclusion

By following the steps outlined above, you should be able to resolve the ngx-spinner type error effectively. Make sure to define not only the type in your busy service but also to include the necessary styles in the angular.json file. This will ensure that your application has a smooth loading experience, providing users with visual feedback during data processing.
