A suite of Go applications using Hasura DDN.

DDN Gopher

This is a bundled suite of applications which you can run with Docker:

• An authentication server, using Gin
• A PostgreSQL database with a users table by default
• A pre-loaded Hasura DDN project which can be run locally
• A starter CLI application, using Bubble Tea

Prerequisites

• Docker
• The Hasura DDN CLI

Let's get up and running

Step 1. Clone the repo

Clone the repo:

git clone https://github.com/robertjdominguez/ddn-gopher

Step 2. Create a .env in the root

Move into the repository:

cd ddn-gopher

Then, create a new .env file with a JWT secret key:

touch ./auth-server/.env && echo "JWT_SECRET=somethingSuperSecureGoesHere!" > ./auth-server/.env

Step 3. Update the AuthConfig

Replace the value for the JWT key in hasura/supergraph_globals/auth-config.hml

With whatever value you used above, replace 3q2+7w==iQ== in this ☝️ file:

kind: AuthConfig
version: v1
definition:
  mode:
    jwt:
      audience: null
      issuer: null
      allowedSkew: null
      claimsConfig:
        namespace:
          claimsFormat: Json
          location: /https:~1~1hasura.io~1jwt~1claims
      tokenLocation:
        type: BearerAuthorization
      key:
        fixed:
          algorithm: HS256
          key:
            value: <your-new-value-here>

Step 3. Start Docker Compose

From the root of the project, run:

 HASURA_DDN_PAT=$(ddn auth print-pat) docker compose up -d
