Lambda HTTP Router Example

This is a simple example to test the performance of a simple HTTP router using AWS Lambda.

Requirements

• go
• docker
• docker-compose
• awslocal-cli
• tflocal-cli

Running the example

1. Set LOCALSTACK_API_KEY to the env

echo LOCALSTACK_API_KEY=xxxxxxx >> .env

2. Start the stack

make start

3. Running the example for the first time

make init
make apply

4. Refreshing the code after the first time

make refresh

5. Destroying the example

make destroy

6. Stopping the stack

make stop

Testing the router

The output from the make apply command will show the URL of the API Gateway. Export this value to the API_URL environment variable. Then use curl to test the router.

export API_URL=http://{API_ID}.execute-api.localhost.localstack.cloud:4566
curl -X GET $API_URL
curl -X GET $API_URL/users
curl -X GET $API_URL/users/1
curl -X DELETE $API_URL/users/1
