It is possible to run the mapshaper-server tool as an AWS Lambda Function URL.
- Start by create a container image by running the
docker build -t mapshaper-server .command. - Upload the container to an AWS ECS repository.
- Create a new Lambda function and configure to use the container image you've just uploaded to ECS.
- Update the "Image Configuration" of your Lambda function and assign the following container override:
/usr/local/bin/mapshaper-server, -server-uri, functionurl:// - Configure your function to a "Function URL". The details of whether your function URL requires authentication or not are left to you to decide.
That's it. You can test your function URL like this (where {FUNCTION_URL_ID} and {AWS_REGION} should be replace with the relevant values in your specific function URL):
$> curl -s https://{FUNCTION_URL_ID}.lambda-url.{AWS_REGION}.on.aws/api/innerpoint \
-d @fixtures/1745882083.geojson \
| jq '.features[].geometry'
