nbb serverless example

This example demonstrates how to deploy and run CLJS code on AWS Lambda NodeJS 14.x runtime using Serverless Framework.

We setup a simple HTTP POST endpoint on API Gateway that proxies requests to a lambda function. index.mjs file works as a bootstrap that uses nbb to load CLJS code when the lambda (cold)starts.

Prerequisities

  • AWS Account and API credentials configured on your system
  • Node

Setup, deployment and testing

  • npm install
  • npx sls deploy

Grab the endpoint URL from the output and call it like this:

curl -X POST -H "Content-Type: application/json" -d '{"x":1,"y":2}' https://1xz3t07x70.execute-api.us-east-1.amazonaws.com/dev/add

...or

 npx sls invoke --function add --data '{"body":"{\"x\":1,\"y\":2}"}'

NOTE: npx sls invoke local does not work due to serverless/serverless#11308

Develop

You can edit the code locally or directly in the Lambda Console.
