How to add query operators to query of Firestore?-CodePudding

I have problem. My app allows user to filter offers by few params. I would like to fetch data with .where() operator by I need to stack them. How can I do it?

My attempt (don't work):

let query = db.collection("cards").where("cardId", "==", id);

  if (filterParams.price.from && filterParams.price.to) {
    query
      .where("price", ">=", filterParams.price.from)
      .where("price", "<=", filterParams.price.to);
  }
  if (filterParams.graded) {
    query.where("isGraded", "==", filterParams.graded);
  }
  if (filterParams.condition) {
    query.where("condition", "==", filterParams.condition);
  }

  query = await query.get();

CodePudding user response：

Query objects are immutable. Each time you call where it returns a new Query object, which you need to then keep a reference to that query.

So:

let query = db.collection("cards").where("cardId", "==", id);

if (filterParams.price.from && filterParams.price.to) {
  query = query //
