GraphQL Endpoint in AWS AppSync (in Go)

View Code

This example shows how to setup a basic GraphQL endpoint in AWS AppSync. The endpoint contains one query and one mutation that get and put items to a Dynamo DB table.

Deploying the App

To deploy your infrastructure, follow the below steps.

Prerequisites

1. Install Go
2. Install Pulumi
3. Configure AWS Credentials

Steps

After cloning this repo, from this working directory, run these commands:

1. Create a new Pulumi stack, which is an isolated deployment target for this example:

   $ pulumi stack init dev
   

2. Set the required configuration variables for this program (AWS Region):

   $ pulumi config set aws:region us-west-2
   

3. Run pulumi up up to preview and deploy changes:

   $ pulumi up
   Previewing update (dev):
   ...
   
   Updating (dev):
   ...
   Resources:
       + 10 created
   Duration: 20s
   

4. Check the deployed GraphQL endpoint:

   $ pulumi stack output endpoint
   https://***.appsync-api.us-west-2.amazonaws.com/graphql
   $ pulumi stack output key
   ***sensitivekey***
   $ curl -XPOST -H "Content-Type:application/graphql" -H "x-api-key:$(pulumi stack output key)" -d '{ "query": "mutation AddTenant { addTenant(id: \"123\", name: \"FirstCorp\") { id name } }" }' "$(pulumi stack output endpoint)" 
   {
       "data": {
           "addTenant": {
               "id": "123",
               "name": "FirstCorp"
           }
       }
   }
   

Clean up

1. Run pulumi destroy to tear down all resources.

2. To delete the stack itself, run pulumi stack rm. Note that this command deletes all deployment history from the Pulumi console.
