Buile up Resize Images on the Fly with Amazon S3, AWS Lambda, and Amazon API Gateway via CDK

Buile up Resize Images on the Fly with Amazon S3, AWS Lambda, and Amazon API Gateway via CDK

Requirement

1. Install AWS CDK using npm install -g aws-cdk
2. Run npm install in repo root directory to install the packages
3. Switch/fix the default AWS profile to be the profile you want to use (profile management is not quite working properly)
4. Run cdk bootstrap to bootstrap the account for CDK usage

Deployment

1. Run npm run build to compile the code (remember to do this whenever there is a code change! or use "npm run watch")
2. cdk deploy deploy this stack to your default AWS account/region

Verification

Output will show your correct endpoint, when you completed the cdk deploy stage.

1. Upload Example Images

aws s3 cp example/hello.jpg s3://$BucketName/

2. open origin image

open browser to http://$BucketName.s3-website-us-east-1.amazonaws.com/hello.jpg

3. open resize image

open browser to http://$BucketName.s3-website-us-east-1.amazonaws.com/400x400/hello.jpg

CleanUP

1. Run "cdk destroy" to delete the stack. This works even if the stack never was created properly in the first place.
