Integrate you Chatterbug leaderboard directly in to Slack. In this repo you'll find all the tools you need to query Chatterbug's GraphQL API, an integration with AWS Lambda and API Gateway, and a Lambda function that returns messages in a format consumable by Slack.
After you have everything deployed, you can create a custom slash command in Slack to get the relevant messages in Slack itself.
There's a small binary that can be built for testing purposes in cmd/chatterbug-leaderboard.
$ go build ./cmd/chatterbug-leaderboardThere's a make target that builds the Lambda function for deployment. It'll output a zip file that can be uploaded to S3.
$ make package
rm -rf bin
mkdir bin
GOOS=linux go build -o ./bin/get-chatterbug-leaderboard ./pkg/lambda/get-chatterbug-leaderboard
cd ./bin && zip get-chatterbug-leaderboard.zip get-chatterbug-leaderboard

$ aws lambda update-function-code \
--function-name get-chatterbug-leaderboard
--s3-bucket chatterbug-leaderboard-artifacts-1-bucket-abc12cedf3456 \
--s3-key get-chatterbug-leaderboard.zip \
--profile my-profile \
--region eu-central-1Everything for running this in Lambda is captured in CloudFormatiion. There are two stacks to manage. The first is for storing the code that will be executed in Lambda and the second is for lambda and API gateway itself. They're split between two stacks because the relevant code needs to exist before the Lambda function can be created.
The process looks like this.
- Create the
artifactsstack. - Build, package, and upload the code to S3.
- Create the
lambdastack.
So first, let's create the artifacts stack.
$ aws cloudformation create-stack \
--stack-name chatterbug-leaderboard-artifacts-1 \
--template-body file://./scripts/cloudformation-artifacts.yaml \
--profile my-profile \
--region eu-central-1 \
--capabilities CAPABILITY_IAMThen you need to upload the code to the bucket that was create. The bucket name is randomly generated by CloudFormation so let's get the bucket name using the following.
$ aws cloudformation describe-stacks \
--stack-name chatterbug-leaderboard-artifacts-1 \
--profile my-profile \
--region eu-central-1
{
"Stacks": [
{
"StackId": "arn:aws:cloudformation:eu-central-1:0123456789:stack/chatterbug-leaderboard-artifacts-1/b62f58e3-d4ea-4ab4-ad70-1d30b37fc19f",
"StackName": "chatterbug-leaderboard-artifacts-1",
"Description": "Chatterbug Leaderboard API artifacts deployment",
"CreationTime": "2022-01-19T08:38:50.115Z",
"RollbackConfiguration": {},
"StackStatus": "CREATE_COMPLETE",
"DisableRollback": false,
"NotificationARNs": [],
"Capabilities": [
"CAPABILITY_IAM"
],
"Outputs": [
{
"OutputKey": "BucketARN",
"OutputValue": "arn:aws:s3:::chatterbug-leaderboard-artifacts-1-bucket-abc12cedf3456"
},
{
"OutputKey": "BucketName",
"OutputValue": "chatterbug-leaderboard-artifacts-1-bucket-abc12cedf3456"
}
],
"Tags": [],
"EnableTerminationProtection": false,
"DriftInformation": {
"StackDriftStatus": "NOT_CHECKED"
}
}
]
}Now upload the relevant code. Notice the reference in the bucket name to the previous CloudFormation output.
$ make package
$ aws s3 cp ./bin/get-chatterbug-leaderboard.zip s3://chatterbug-leaderboard-artifacts-1-bucket-abc12cedf3456/get-chatterbug-leaderboard.zip \
--profile my-profile \
--region eu-central-1Now create the lambda stack. Note the parameters need to be updated to reflect the actual stack name you used as well as include your Chatterbug API token.
$ aws cloudformation create-stack \
--stack-name chatterbug-leaderboard-lambda-1 \
--template-body file://./scripts/cloudformation-lambda.yaml \
--parameters ParameterKey=ArtifactsStackName,ParameterValue=chatterbug-leaderboard-artifacts-1 ParameterKey=ChatterbugAPIToken,ParameterValue=DEADBEEF\
--profile my-profile \
