Question

A promise was caught with the following error: "Error in ./Search class Search - inline template:4:0 caused by: Maximum call stack size exceeded"

As a newcomer to Angular2, I am currently developing a web application that requires three separate calls to a REST API. To test these calls, I decided to simulate the API responses by creating three JSON files with the necessary data. However, my implementation is not functioning as intended, and upon checking the developer console, I encountered the following error:

Uncaught (in promise): Error: Error in ./Search class Search - inline template:4:0 caused by: Maximum call stack size exceeded

Please refer to the code snippets below for more details:

The template - search.template.html:

<search>
  <h1>Angular2 HTTP Demo App</h1>
  <h2>Foods</h2>
   <!-- Rest of the HTML content goes here -->
</search>

I seem to be stuck trying to identify the root cause of this error within the codebase. If anyone could provide some insights or assistance on resolving this issue, it would be greatly appreciated. Thank you!

Answer №1

After examining your search.template.html, the recommendation is to eliminate the use of <search> tags. The presence of this search tag in the HTML template is causing a recursive issue, ultimately resulting in an error indicating that the Maximum call stack size has been exceeded.

Instead, structure your template as shown below-

  <h1>Angular2 HTTP Demo App</h1>
  <h2>Foods</h2>
  <ul>
    <li *ngFor="let food of foods"><input type="text" name="food-name" [(ngModel)]="food.name"><button (click)="updateFood(food)">Save</button> <button (click)="deleteFood(food)">Delete</button></li>
  </ul>
  <p>Create a new food: <input type="text" name="food_name" [(ngModel)]="food_name"><button (click)="createFood(food_name)">Save</button></p>
  <h2>Books and Movies</h2>
  <h3>Books</h3>
  <ul>
    <li *ngFor="let book of books">{{book.title}}</li>
  </ul>
  <h3>Movies</h3>
  <ul>
    <li *ngFor="let movie of movies">{{movie.title}}</li>
  </ul>

Please make these adjustments and see if it resolves the issue at hand.
