Connecting Hasura to a Supabase Postgres Database
This guide explains how to connect a new or existing Supabase Postgres database to a Hasura instance, either on Hasura Cloud or via one of our self-hosted solutions. If you're exploring Supabase Postgres and are interested in migrating an existing Postgres database - such as from Heroku - check out their docs before continuing below.
If you plan on using Hasura Cloud, which we recommend, follow steps 1 and 2 below. If you're self-hosting a Hasura instance and already have a project running, skip to step 3.
Step 1: Sign up or log in to Hasura Cloud
Navigate to Hasura Cloud and sign up or log in.
Step 2: Create a Hasura Cloud project
On the Hasura Cloud dashboard, create a new project:
After the project is initialized successfully, click on
Launch Console to open the Hasura Console in your browser.
On the Hasura Console, navigate to the
Data tab and choose
Connect Existing Database. Hasura will prompt you for a
Postgres Database URL. We'll create this in the next step and then come back here.
Step 3: Create a Postgres DB on Supabase
Log into Supabase using your GitHub login.
From your dashboard, click
If you don't already have an organization within Supabase, you'll need to create a one. Click
Fill in a name and click
After creating your organization, you'll be presented with the
Create a new project view. Fill in the necessary
information and click
Create new project:
You'll be redirected to your project's dashboard. After a few minutes, your database should be provisioned. You'll know you're ready once your dashboard changes from this:
Congratulations! You've now created a Postgres instance on Supabase which you can use with Hasura GraphQL Engine. Follow the steps below to connect it to Hasura.
Step 4: Get the database connection URL
The structure of the database connection URL looks as follows:
From your database's dashboard, click the
Settings icon on the side navigation:
Then scroll down to find the
Connection string section. Select the
URI option and copy the string:
You'll need to replace
[YOUR-PASSWORD] with your project's password.
Step 5: Finish connecting the database
Back on the Hasura Console, enter the database URI that we retrieved in the previous step:
For security reasons, it is recommended to set database URLs as env vars and using the env vars to connect to the databases in place of the raw database URLs.
Voilà. You are ready to start developing.
