What is the best way to remove specific records from a FirebaseTS Database using Angular 13?

Hi there! I'm still getting the hang of the Angular framework, so please bear with me. Currently, I have a feed or timeline consisting of simple posts that contain text. This text is stored in Firebase using the following method:

firestore = new FirebaseTSFirestore();

createItem(postInput: HTMLInputElement) {
    let postMessage = postInput.value;
    let postId = this.firestore.genDocId();

    this.firestore.create(
      {
        path: ["Posts", postId],
        data: {
          postMessage: postMessage,
          timestamp: FirebaseTSApp.getFirestoreTimestamp()
        }
      }
    )
  }

The Posts folder contains documents with randomly generated names achieved through

let postId = this.firestore.genDocId();
. Each document represents a post on my timeline. I also have a "trash bin" icon within my post HTML component which will serve as a delete button.

<span><i class="fa fa-trash"></i></span>

Here's an example of how the list appears: timeline

My question is, how can I delete the document associated with the trash icon? I've searched online but haven't found much information. Any guidance on how to achieve this would be greatly appreciated.

Thanks in advance!

Answer №1

  • In order to implement the delete functionality, you must create a click function and include the element ID in conjunction with your icon like this:

    <i class="fa fa-trash" (click) = removeItem(id)” >

  • Next, within your TypeScript component, define the following method:

    removeItem(id:any) { this.firestore.db.collection(‘collection name’).doc(id).delete()
