<h1>BUG: RxJs chaining operators</h1>
|
|
|
|
> Author: Thomas Laforge
|
|
|
|
Let's dive inside the wonderful word of RxJs.
|
|
|
|
This challenge is inspired by a real-life example.
|
|
|
|
### Presentation of the challenge
|
|
|
|
#### User Story
|
|
|
|
We need a button for each `Topic`. When we click on it, we delete all objects with this `Topic` in our database _(Fake DB in our case)_. Finally we display **All [topic] have been deleted** is everything was deleted successfully or **Error: deletion of some [topic] failed** if some deletions failed
|
|
|
|
#### Constraints:
|
|
|
|
We can only pass one object to our DB for deletion at the time. The DB will respond true if the data was successfully deleted and false otherwise.
|
|
|
|
### What you need to do
|
|
|
|
The QA team reports a **bug**. The UI shows **All [topic] have been deleted** all the time, even if some deletions fail.
|
|
|
|
👉 Spot the bug and correct it.
