Dependencies
The Image Resize Core is built using Node.js and various supporting packages:
- aws-sdk - The official AWS SDK is used for all interactions with DynamoDB, S3 and Lambda. Since images and archives are stored in S3, this is essentially used for every API request.
- lodash - Lodash is a collection of helper methods which is primarily used for input validation as it has lots of tools for type validation.
-
probe-image-size - Determines the width and height of an image. Used to provide the
dimensionsproperty on the /imageEditors and /images APIs. - readable-stream - Node.js streams, but in a module. This allows us to work with a consistent stream API (node.js 8 streams in this case) while in any node environment.
