Graphql Yoga Sample App

The ts-graphql-yoga sample application demonstrates how to use the @klotho::expose annotation with a graphql-yoga server. The sample application defines a graphql endpoint to run queries and mutations against.

Prerequisites

This guide assumes:

• pulumi is configured with the proper AWS credentials

Run the app locally

run the terminal commands:

npm install
npx ts-node index.ts
# [email protected] start
# ts-node src/index.ts
# Server is running on http://localhost:3000/graphql

Running queries through the browser

# hello
  query {
    hello
  }

# > {
# >  "data": {
# >    "hello": "Hello from Klotho!"
# >  }
# > }

Compile and Deploy with Cloudcc

run the terminal commands:

# Compile the app
npx tsc && klotho . --app ts-graphql-yoga -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-graphql-yoga

# npm install
npm install

# Deploy
pulumi up -s ts-graphql-yoga

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

Calling your service

# Add a user 
curl 'https://<...>.execute-api.<YOUR_REGION>.amazonaws.com/stage/graphql' -X POST -H 'content-type: application/json' --data '{"query": "query {hello}"}'
# > {"data":{"hello":"Hello from Klotho!"}}%

Clean Up

From the compiled directory still,

# Tear down when done
pulumi destroy -s ts-graphql-yoga
