Firestore Index Rules format JSON-CodePudding

I'm relatively new to Firebase and Firestore, I have created 2 Index in the firestore web app and seems like I also have to update the firestore.indexes.json on my IDE.

Base from the image above, is this the correct way of adding it on VSCODE? I'm just assuming it is.

{
  "indexes": [
    {
      "collectionGroup": "timeinout",
      "queryScope": "COLLECTION",
      "fields": [
        {
          "fieldPath": "uid",
          "order": "ASCENDING"
        },
        {
          "fieldPath": "createdAt",
          "order": "ASCENDING"
        },
        {
          "fieldPath": "uid",
          "order": "ASCENDING"
        },
        {
          "fieldPath": "timein",
          "order": "ASCENDING"
        }
      ]
    }
  ],
  "fieldOverrides": []
}

CodePudding user response：

The index definition is almost there, but it will only create one index, across all four of those fields (one of which, uid, will be duplicated).

To create 2 indexes, you can put 2 entries in the indexes array rather than putting all 4 fields into a single index entry:

{
  "indexes": [
    {
      "collectionGroup": "timeinout",
      "queryScope": "COLLECTION",
      "fields": [
        {
          "fieldPath": "uid",
          "order": "ASCENDING"
        },
        {
          "fieldPath": "createdAt",
          "order": "ASCENDING"
        }
      ]
    },
    {
      "collectionGroup": "timeinout",
      "queryScope": "COLLECTION",
      "fields": [
        {
          "fieldPath": "uid",
          "order": "ASCENDING"
        },
        {
          "fieldPath": "timein",
          "order": "ASCENDING"
        }
      ]
    }
  ],
  "fieldOverrides": []
}
