Firestore / Firebase Typesense Search Extension 🔍

CircleCI

A Firebase extension to sync data from your Firestore collection to Typesense, to be able to do full-text fuzzy search on your Firestore data, with typo tolerance, faceting, filtering, sorting, curation, synonyms, geosearch and more.

This extension listens to your specified Firestore collection and syncs Firestore documents to Typesense on creation, updates and deletes. It also provides a function to help you backfill data.

What is Typesense?

If you're new to Typesense, it is an open source search engine that is simple to use, run and scale, with clean APIs and documentation. Think of it as an open source alternative to Algolia and an easier-to-use, batteries-included alternative to ElasticSearch. Get a quick overview from this guide.

⚙️ Usage

1. Setup Prerequisites

Before installing this extension, make sure that you have:

  1. Set up a Cloud Firestore database in your Firebase project.
  2. Set up a Typesense cluster (on Typesense Cloud or Self-Hosted).
  3. Set up a Typesense Collection either through the Typesense Cloud dashboard or through the API.

2. Install the Extension

You can install this extension either through the Firebase Web console or through the Firebase CLI.

Syncing Multiple Firestore collections

You can install this extension multiple times in your Firebase project by clicking on the installation link above multiple times, and use a different Firestore collection path in each installation instance. Here is a screenshot of how this looks.

3. Backfilling data (optional)

This extension only syncs data that was created or changed in Firestore, after it was installed. In order to backfill data that already exists in your Firestore collection to your Typesense Collection:

  • Create a new Firestore collection called typesense_sync through the Firestore UI.
  • Create a new document with the ID backfill and contents of {trigger: true}

This will trigger the backfill background Cloud function, which will read data from your Firestore collection and create equivalent documents in your Typesense collection.
