Is it able to query a objects where it's property(a list) contain certain value?

Question

For example, I have a list like this, and I wanna search for objects which have the child "apple", is it doable?

[{id: 1, child:["apple", "tomato", "potato"]}, {id: 1, child:["potato"]}, ...]

Are those objects direct children of your root reference? – Alex Mamo Dec 20 '22 at 10:37 — Alex Mamo, Dec 20 '22 at 10:37
Yes, and the data is from the firebase realtime database. – Ian Dec 20 '22 at 12:07 — Ian, Dec 20 '22 at 12:07

That's just basic Javascript ... You should be able to do it yourself. Otherwise, you should learn Javascript instead of Angular.

Nevertheless, use the according tags.

And here is your answer.

const apples = data.filter(item => item.child.includes('apple'));

I know I could load all the data and filter it out. I was wondering if there is any way to do it on the firebase side. Thanks. – Ian Dec 20 '22 at 09:46
