This is a reference implementation for viewing Aperio SVS digital slide images that are stored in Amazon S3.
The S3VS front-end (web) uses OpenSeadragon and is meant to be embedded in an existing application. Once the back-end is deployed, set the service endpoint in config.js
, and then you can test the front-end in standalone mode like so:
npx http-server web
or
npx serve web
or
npx servor --static web
The S3VS back-end (api) is implemented as an AWS Serverless application. It creates a Lambda function that translates IIIF image requests to S3 byte-range fetches against the .svs file in an S3 bucket. It relies on a modified implementation of OpenSlide to read the .svs files from an S3 bucket.
This implementation uses Amazon API Gateway with an API mapping to a custom domain. If your front-end uses AWS Signature Version 4 signed requests (e.g. using AWS Amplify), another option for the API on AWS is a S3 Object Lambda REST endpoint with a DNS alias record.
