ORM Environment Variable Directive Sample App

The sequelize sample app shows how to use the klotho::persist annotation, with an environment variable directive, to inject the connection string onto the sequelize client.

Prerequisites

This guide assumes:

Run the app locally

npm i
export ORM_CONNECTION_STRING="sqlite::memory:" 
npx ts-node index.ts

Hit your endpoints:

curl http://localhost:3000/item -X POST -d '{"key": "test_key", "value": "test_value"}' -H "Content-Type: application/json"
# > success%

curl http://localhost:3000/item/test_key
# > test_value%

Compile and Deploy with Klotho

Run the terminal commands:

# Compile the app
npx tsc && klotho . --app ts-orm-env-var -p aws

# Go into the compiled directory
cd compiled

# If you didn't set the aws region as indicated in the compiler output, do that now
pulumi config set aws:region YOUR_REGION -s ts-orm-env-var

# Set username and password
pulumi config set ts-orm-env-var:sequelizedb_username <USERNAME> -s ts-orm-env-var
pulumi config set --secret ts-orm-env-var:sequelizedb_password <PASSWORD> -s ts-orm-env-var

# npm install
npm install

# Deploy
pulumi up -s ts-orm-env-var

# Outputs: {
#   apiUrl: 'https://<...>.execute-api.<YOUR_REGION>.amazonaws.com/stage/'
# }

Calling your service

# Add a user 
curl -X POST  https://<...>.execute-api.<YOUR_REGION>.amazonaws.com/stage/item -d '{"key": "test_key", "value": "test_value"}' -H "Content-Type: application/json"
# > success

# Get all users
curl  https://<...>.execute-api.<YOUR_REGION>.amazonaws.com/stage/item/test_key
# > 100

Clean Up

From within the compiled directory

# Tear down when done
pulumi destroy -s ts-orm-env-var
