Connecting Hasura to an ElephantSQL Postgres Database
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 ElephantSQL
Log into ElephantSQL.
If this is your first time logging into ElephantSQL, you'll need to create a team. Complete the form and click
From here, you'll need to create a new instance:
Choose a name, plan, and - if necessary - tags for this instance. Click
Select Region when complete:
Choose a region and click
Confirm your selections and click
Congratulations! You've now created an ElephantSQL Postgres instance you can use with Hasura GraphQL Engine. Follow the steps below to connect it to Hasura.
Step 4: Get the database connection URL
From your dashboard, click on the name of your instance:
The structure of the database connection URL looks as follows:
Details view, copy the URL string to your clipboard:
Step 5: Finish connecting the database
Back on the Hasura Console, enter the database URL 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.
