Serverless EventBridge example

This example demonstrates how to add events to the default bus and a custom bus and how to trigger event rules.

Use-case

De-coupling microservices using the AWS EventBridge service

Setup

npm i -g serverless
npm i
sls deploy

Send a message to Alice Lambda

curl -X POST -H "Content-Type:application/json" https://XXXXXXX.execute-api.us-east-1.amazonaws.com/alice 
--data '{ "messageSentToAlice": "Learn Serverless" }'

Example Result:

{"message":"Alice was called"}

Alice leaves an event on a custom bus. Bob is listening for events that Alice creates.

Dave is a schedule cron Lambda that runs every 10 minutes. Dave picks a random number between 1 and 151 and fetches the Pokemon from PokeAPI for that random number.

Eve has lots of rules she is listening for on the default EventBridge bus including scheduled events like Dave.
