Is there a way to make two separate API calls within the same Angular component? For instance, I have an order component that is rendered twice in a tabular manager on a page. Using ngif condition, I display different data for TAB1 and TAB2. The issue is that API1 call occurs automatically when the page loads, while API2 call should only happen when TAB2 is clicked. Is it possible to achieve this functionality without creating a new component?
To handle the input effectively and make decisions accordingly, consider developing a unique component like this:
<custom-component [enableApiCall]=true></custom-component>if(enableApiCall) performApiCall();Initially executed within ngOnInit. Subsequently inside the catch function of selectedIndexChange.
Hey, I understand your point. You can actually handle both API calls using just one component by implementing two separate functions. I suggest trying this approach: The first API call will be executed when the page loads, and then, on clicking TAB2, you can call a function that triggers the second API call. Meanwhile, you can display a loader on the user interface to indicate the loading process. This solution should solve your problem.
Also, as an alternative suggestion, you could consider making both API calls on page load and then use the ngIf directive to hide or show your data based on whether TAB1 or TAB2 is clicked.
Please let me know if either of these solutions work for you.
When faced with such scenarios, it is recommended to utilize a reactive programming approach. Follow these steps: 1) Within your service file, write the API call and return an observable object. 2) Use the pipe operator and employ the rxjs sharereplay operator while creating this observable. 3) Create two variables of type Observable - input1$ = Observable and input2$ = Observable. Both will store the response from the API, allowing you to perform necessary manipulations like mapping or filtering in any subsequent calls. 4) Bind these observables to your HTML using the async pipe.
This approach offers several benefits, especially when the same API call is required multiple times within the component. By not invoking it twice, the data remains consistent. To gain a better understanding, watch this helpful video here.
