  2. Deploying an Index in GCP Firestore with TypeScript

How do I deploy an index in GCP Firestore with TypeScript?

In this guide, we will deploy an index in Google Cloud Firestore using Pulumi and TypeScript. Firestore indexes are critical for efficient querying and performance optimization. We will create a Firestore index in a specified collection with specific fields and configurations.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

// Define the Firestore index
const firestoreIndex = new gcp.firestore.Index("firestoreIndex", {
    project: "your-gcp-project-id", // Replace with your GCP project ID
    collection: "your-collection-name", // Replace with your Firestore collection name
    fields: [
        {
            fieldPath: "fieldName1", // Replace with your field name
            order: "ASCENDING"
        },
        {
            fieldPath: "fieldName2", // Replace with your field name
            order: "DESCENDING"
        }
    ],
    queryScope: "COLLECTION"
});

// Export the URL of the created index
export const indexUrl = pulumi.interpolate`https://console.cloud.google.com/firestore/indexes?project=${firestoreIndex.project}`;

Key Points

  • We imported the necessary Pulumi and GCP packages.
  • We defined a Firestore index using gcp.firestore.Index.
  • The index is configured with fields and their respective sorting orders.
  • The queryScope is set to COLLECTION, meaning the index is scoped to a single collection.
  • The URL of the created index is exported for easy access.

Summary

We successfully deployed a Firestore index in Google Cloud using Pulumi and TypeScript. This index will optimize query performance for the specified fields in the given collection. Adjust the project ID, collection name, and field names as per your requirements.
