TypeScript Compile Error: The property is not available in the 'IStateParamsService' type

My client project heavily utilizes TypeScript. Currently, I am encountering a technical issue.

Within my HTML code, I have an anchor tag as shown below:

<a class="btn btn-default mrm" ui-sref="course-detail({courseId: '{{c.Id}}'})">Details</a>

In my course detail controller, I am retrieving the values in the stateparam variable. However, when attempting to access the 'courseId' from that variable, a build error occurs. Please refer to the image below for clarification.

If I remove the IF block, I can successfully log the output in the developer console as displayed in the image below.

Obtaining the course Id property and value is crucial for the continuation of my project. Otherwise, I may be forced to rewrite this controller using pure AngularJS, which is not my preferred approach. Thank you.

Answer №1

When utilizing TypeScript, it is recommended to access maps explicitly using brackets notation [].

To retrieve a specific field from a map-like object, square brackets should be used instead of dot notation:

if (this.param['courseId'] === "00000....0000") {
  //.. continue with the remaining code

This approach should effectively address the immediate issue you are encountering.
