• GraphQL API: Efficient data fetching with GraphQL.

Architecture

The application is composed of the following components:

1. Frontend: Next.js for the user interface.
2. Backend: NestJS with GraphQL for API management.
3. Database: PostgreSQL for persistent storage.
4. Cache: Redis for caching data.
5. Infrastructure: Terraform automates the provisioning of EC2 instances in AWS.
6. CI/CD: GitHub Actions automates the build and deployment process.

Deployment

1. create ECR in AWS you have to create to ECR for frontend and backend dockers.
2. setting up the parameters set the parameters in AWS parameter store.

   # Replace values with your actual secrets
   aws ssm put-parameter --name "/tenant-test/OPENAI_API_KEY" --type "SecureString" --value <OPENAI-API-KEY> --overwrite
   aws ssm put-parameter --name "/tenant-test/POSTGRES_USER" --type "SecureString" --value <POSTGRE-USER> --overwrite
   aws ssm put-parameter --name "/tenant-test/POSTGRES_PASSWORD" --type "SecureString" --value <POSTGRES-PASSWORD> --overwrite
   aws ssm put-parameter --name "/tenant-test/POSTGRES_DB" --type "SecureString" --value <POSTGRES-DB-NAME> --overwrite
   aws ssm put-parameter --name "/tenant-test/DATABASE_URL" --type "SecureString" --value "postgresql://<POSTGRE-USER>:<POSTGRES-PASSWORD>@postgres:5432/<POSTGRES-DB-NAME>" --overwrite
   aws ssm put-parameter --name "/tenant-test/REDIS_URL" --type "String" --value "redis://redis:6379" --overwrite
   

3. Setup the github environment variable you have to setup the following variable in github:

   AWS_ACCESS_KEY_ID
   AWS_REGION
   AWS_SECRET_ACCESS_KEY
   EC2_PRIVATE_KEY
   ECR_REPOSITORY
   

4. Pushing in main branch Now just push to main branch everything is up and running in few minutes.
