Shared App Dependencies

I would like to create a library for Devvit, and while it would be possible to include my library using package.json, it would be more efficient if multiple apps on the same subreddit could share the same code and data. My library would listen for a trigger, process the data, and store the changes in Redis. Currently every app using my library would each do these same steps. If my library could be shared, then these steps would only happen once, and each app would be able to read the same final data.

Start by reviewing the package.json-based library inclusion described in the issue, then trace how Devvit apps listen for triggers and store data in Redis. Define what shared code and data would mean for multiple apps on one subreddit, and consider how completion would be verified when processing occurs only once and apps can read the final data.
