This sub-project implements a basic Image management API in GCP. (index.js)

Please note: index.js contains the latest functioning code. experiments/ is from my initial experimentation and may not be functional.

The first phase on this module has been completed. This encompasses the basic functionality of uploading a remote image (via stream), and providing a signed URL by which to access that image. It consists of one REST end point.

1. Create Project and add Project_ID to config.json
2. Create a service account with access to upload Google Functions and save the key in keys/gcp_functions.json
3. Create Bucket in Google Cloud Storage and update bucket_name in config.json
4. Create a service account with write permissions to your google storage bucket and save the key in keys/gcp_storage.json

• Filetype verification
• Partitioned file uploads
• Caching
  • Match Cache expiry to Bucket item expiration
• Add script to deploy.sh to add Project_ID to bucket name
• Security and signing

The item expiry can be handled directly in the data bucket policy. gsutil mb --retention 80d gs://ImageAPI (For a more nuanced/extensible approach we could specify a more detailed lifecycle policy or have a lambda function launched via scheduled CRON job - eg. via cloud scheduler)

The gcloud deploy command, unfortunately, appears to only work on a singular local index.js file (or remote repositories).

Google's AppEngine provides ready made image servicing, including resizing and cropping. https://cloud.google.com/appengine/docs/standard/python/refdocs/google.appengine.api.images#google.appengine.api.images.get_serving_url https://medium.com/google-cloud/uploading-resizing-and-serving-images-with-google-cloud-platform-ca9631a2c556

We're currently utilizing Google's prebuilt node module for access. For a smaller footprint, to aid with speed of load for the cloud functions, we could use a streamlined request library to interact directly with their REST API.
