To keep your data up to date with your subreddit, it is expected that you run
reddinx.incremental() on a regular basis. Because manually running the command
and committing the results is not sustainable, you should find a way to run it
automatically for you.
As an example, here is how I configured it to automatically update the content of https://gamemaster.pixelastic.com/maps/ with new posts from /dndmaps.
First, I configured CircleCI to run the yarn run ci:dailyUpdate script
every day. This script then runs an incremental update, commit the changes,
push them back to the repository and updates my Algolia search index.
If you're looking for an easy way to run sandboxed scripts on CircleCI, check on-circle.
