Redis Environment Variable Directive Sample App

The redis sample app shows how to use the klotho::persist annotation, with an environment variable directive, to inject host and port onto a node.js redis client to store data.

Prerequisites

This guide assumes:

• pulumi is configured with the proper AWS credentials

Run the app locally

To install Redis locally, follow the instructions on the official Redis getting started page

npm i 
npx ts-node index.ts

Hit your endpoints:

curl -X POST http://localhost:3000/user -d '{"firstName": "john", "lastName": "doe"}' -H "Content-Type: application/json"
# > success%

curl http://localhost:3000/user/john
# > doe%

Compile and Deploy with Klotho

Run the terminal commands:

# Compile the app
npx tsc && klotho . --app ts-redis-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-redis-env-var

# npm install
npm install

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

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

Calling your service

# Add a user 
curl -X POST  https://<...>.execute-api.us-east-1.amazonaws.com/stage/user -d '{"firstName": "john", "lastName": "doe"}' -H "Content-Type: application/json"
# > success

# Get a users last name
curl https://<...>.execute-api.us-east-1.amazonaws.com/stage/user/john
# > doe

Clean Up

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