Hasura Setup

Alright, we're about to begin our foray into authentication with Hasura.

First off, we need to do some set up.

Config Variables

Since we have deployed Hasura GraphQL Engine on Hasura Cloud, let's head to Hasura Cloud Dashboard to configure the JWT secret.

Open the Hasura Cloud dashboard and head to the "Env vars" page for your Hasura Cloud project:

Click on + New Env Var to add a new environment variable.

Add a new Config Var called HASURA_GRAPHQL_JWT_SECRET, and copy and paste the json below into the value box.

Copy
{
  "type": "HS256",
  "key": "JWTSecretMustBeAtLeast32CharactersLong!"
}

You should end up with something like the following:

Replace the key with any key you want but it must be at least 32 characters long.

You should end up with something like the following:

Permissions and Roles

Next up, go to your Hasura console. Refresh it if it was already open. You'd be asked to login to Hasura Cloud Dashboard.

Next up, go to the Data tab and click the users table.

We shall add another column called

password (String, nullable)

Go to Insert Row and add another mock user

Next, go to the Permissions tab and create a new role called user

Set Insert, Update, Select, and Delete permissions
