An AWS Lambda function in Go for archiving a list of data from URLs

SmushIt

A Lambda function using the Go 1.x runtime that takes a list of URLs, archives the data from them in a zip file, and provides a download URL.

Local Development

Install and use AWS SAM Local for local testing. This will use the template.yml file as a definition of the function to test.

1. Start the local API: sam local start-api
2. Make changes to the code
3. Build the code: GOOS=linux GOARCH=amd64 go build -o main main.go
4. Use the included Postman collection for testing requests against the code

AWS Lambda

1. Archive the built artifact: zip main.zip main
2. Upload it to your Lambda function: aws lambda update-function-code --function-name archive --zip-file fileb://main.zip

Example Request

The request body takes a filename and array of URLs. The filename is used as the filename for anyone who downloads the archive file that is created from the files in the "urls" array.

curl -X POST \
  http://127.0.0.1:3000/archive \
  -H 'Cache-Control: no-cache' \
