Can the push() method be utilized to insert an element into an observable array?

I've initialized an array of type string called products using the Observable interface as shown below:

products: Observable<string[]>;

Now, I need to add elements to the products array without using the subscribe method. Unfortunately, the normal push method is not working in this case. Here's the code snippet that's causing an issue:

this.products.push("mova");

Can you suggest an alternative way to add elements to an array without using dependency injection or subscribing methods? Please provide a simple solution.

Answer №1

When working with an Observable of type string[], you cannot directly push values to the property as it is designed to handle a stream of data that will be set in the future.

To work around this, you can follow these steps:

products: Observable<string[]>;
items: string[] = [];

// Push values into the items array.

this.products = of(items); // <--This will set the Observable of string[]

Remember, you still need to subscribe to the products observable to access the data.
