Use this file to discover all available pages. [Supabase](https://supabase.com/?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) is a Backend-as-a-Service (BaaS) app development platform that provides hosted backend services such as a Postgres database, user authentication, file storage, edge functions, realtime syncing, and a vector and AI toolkit. It's an open-source alternative to Google's Firebase. Supabase automatically [generates a REST API](https://supabase.com/docs/guides/api?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) from your database and employs a concept called [row level security (RLS)](https://supabase.com/docs/guides/auth/row-level-security?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) to secure your data, making it possible to directly interact with your database from your React Native application without needing to go through a server! Supabase provides a TypeScript client library called [`supabase-js`](https://supabase.com/docs/reference/javascript/introduction?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) to interact with the REST API. Alternatively, Supabase also exposes a [GraphQL API](https://supabase.com/docs/guides/database/extensions/pg_graphql?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) allowing you to use your favorite GraphQL client (for example, [Apollo Client](https://supabase.github.io/pg_graphql/usage_with_apollo/)) should you wish to. Prerequisites 2 requirements 1. A Supabase project Head over to [database.new](https://database.new?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) to create a new Supabase project. 2. Project URL and Publishable key Get the **Project URL** from the API settings and **Publishable key** from the API Keys: 1. Go to the [API Settings](https://supabase.com/dashboard/project/_/settings/api) page in the Dashboard. 2. Find your Project `URL` and `service_role` keys on this page. 3. Then go to the [API Keys](https://supabase.com/dashboard/project/_/settings/api-keys). 4. Find your Project **Publishable key** on this page under the API Keys tab. ## Using the Supabase TypeScript SDK Using [`supabase-js`](https://supabase.com/docs/reference/javascript/introduction?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) is the most convenient way of leveraging the full power of the Supabase stack as it conveniently combines all the different services (database, auth, realtime, storage, edge functions) together. ### Install and initialize the Supabase TypeScript SDK After you have created your [Expo project](/get-started/create-a-project), install `@supabase/supabase-js` and the required dependencies using the following command: ```sh npx expo install @supabase/supabase-js expo-sqlite ``` Create a helper file to initialize the Supabase client (`@supabase/supabase-js`). You need the API URL and the `Publishable` key copied [earlier](/guides/using-supabase#get-the-api-keys). These variables are safe to expose in your Expo app since Supabase has [Row Level Security](https://supabase.com/docs/guides/auth/row-level-security?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) enabled in the Database. ```ts import 'expo-sqlite/localStorage/install'; import { createClient } from '@supabase/supabase-js'; const supabaseUrl = YOUR_REACT_NATIVE_SUPABASE_URL; const supabasePublishableKey = YOUR_REACT_NATIVE_SUPABASE_PUBLISHABLE_KEY; export const supabase = createClient(supabaseUrl, supabasePublishableKey, { auth: { storage: localStorage, autoRefreshToken: true, persistSession: true, detectSessionInUrl: false, }, }); ``` Now you can `import { supabase } from '/utils/supabase'` throughout your application to leverage the full power of Supabase! ## Next steps [Build a User Management App](https://supabase.com/docs/guides/getting-started/tutorials/with-expo-react-native?utm_source=expo&utm_medium=referral&utm_term=expo-react-native) — Learn how to combine Supabase Auth and Database in this quickstart guide.
