SFTP New File Handler

This repo provides the code for the Lambda function that handles new SFTP uploads for the Prior Art Archive. Each file uploaded via SFTP is:

  • Assigned a UUID,
  • Appended with metadata for UUID and original filename,
  • Copied to its final destination bucket.

On the Lambda function, the following environment variables must be set:

  • sourceBucket: The name of the source S3 bucket.
  • destinationBucket: The name of the destination S3 bucket.
  • idResolverUrl: A URL that will be sent a GET request with ?slug=example and should return the id of the Organization with that slug.

To build the Lambda trigger, use the yarn package command and deploy the resulting deploy.zip through the Lambda interface.

Testing and Deployment

This project does not currently use a Lambda framework, so deployment and testing must be done manually using the AWS Lambda interfaces.

However, we have a nice yarn script to bundle the project in a format that can be uploaded to Lambda:

> yarn package

This will generate a deploy.zip file which can be uploaded to Lambda.

Styles / Linting

We use eslint, to check that your contribution meets the style guidelines just run:

> yarn lint
