Cloud Firestore Database and Operations

Before setting up dependencies, writing data models, or configuring security rules, you MUST always identify the Firestore instance edition.

1. Instance Selection and Edition Detection

Run the following command to list current Firestore databases: bash npx -y firebase-tools@latest firestore:databases:list

A. Instance Found

  1. For each database found, inspect its edition and details: bash npx -y firebase-tools@latest firestore:databases:get <database-id>
  2. Ask the user which database instance they wish to target or if they would prefer to create a new instance.
  3. Once the target instance is established:
    • If the edition is STANDARD, follow the guides under references/standard/.
    • If the edition is ENTERPRISE or native mode, follow the guides under references/enterprise/.

B. No Instance Found (or New Requested)

If no databases exist or the user requests a new one, default to provisioning an Enterprise edition database: bash npx -y firebase-tools@latest firestore:databases:create <database-id> --edition="enterprise" --location="nam5" - Proceed with using the guides under references/enterprise/.

2. Specialized Guides

Based on the identified or created instance edition, open and read the corresponding reference guides:

Standard Edition (references/standard/)

Enterprise Edition / Native Mode (references/enterprise/)
