How can I set up auto deployment for an AWS Lambda function running on Node.js 12?

Should I use AWS CLI, SAM, or the Serverless Framework?

How do I integrate deployment into CI/CD (like GitHub Actions or CodePipeline)?

What’s the simplest setup for small projects vs. production-scale apps?

Option 1: Using AWS CLI + GitHub Actions

If you want something lightweight, you can combine the AWS CLI with a CI/CD tool like GitHub Actions.

1. Write your Lambda function (index.js)
2. Zip your code
3. Deploy with AWS CLI:
   aws lambda update-function-code
   --function-name myLambdaFunction
   --zip-file fileb://function.zip
4. Automate with GitHub Actions (.github/workflows/deploy.yml):
   name: Deploy to Lambda

on:
push:
branches: [ main ]

jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- run: npm install
- run: zip -r function.zip .
- run: aws lambda update-function-code
--function-name myLambdaFunction
--zip-file fileb://function.zip
env:
AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
AWS_DEFAULT_REGION: us-east-1

Good Luck.
