🦕 Typesaurus

TypeScript-first ODM for Firestore.

Looking for React adaptor? Check Typesaurus React!

Why?

• Designed with TypeScript's type inference in mind
• Universal code (browser & Node.js)
• Uncompromised type-safety
• Code autocomplete
• Say goodbye to any!
• Say goodbye to exceptions!
• Ready to start? Follow this guide.

Installation

The library is available as an npm package. To install Typesaurus, run:

npm install --save typesaurus firebase firebase-admin

Note that Typesaurus requires the firebase package to work in the web environment and firebase-admin to work in Node.js. These packages aren't listed as dependencies, so they won't install automatically with the Typesaurus package.

Features

• Complete type-safety: uncompromised type-safety, includes Firestore quirks.
• Universal package: reuse the same code on the client and server.
• JavaScript-native: converts Firestore data types, i.e. timestamp, to native JS types, i.e. Date.
• Build size-efficiency: optimized build-size for web.
• Typed ids: all document ids are types, so you'll never mix up a user id with an account id.
• Centralized schema: easy to define, read and update.
• Single-import principle: single import to define, single import to use.
