Edge deployment and SQLite about node-gtfs

[AvidDabbler]

You could also run this in a Github action which would trigger a redeploy and store it in the repo. I have been playing around with storing the db on a remix server with Simple Transit Site. I am persisting the db in s3 using a cron job and pulling it down in the Dockerfile and then running the Gtfs update.

I know that there are other options like Litestream, but it does not work with the DigitalOcean platform for some reason.

@laem You are correct - I build the db locally and then check it into the git repo along with the code for the project and then deploy (via git) to Vercel. So it is all bundled together. Whenever there is an update to the GTFS, I make a new commit to the repo.

That might not work well with very large agencies GTFS or for GTFS that changes very frequently.

I'd like to add support for more databases other than sqlite3, perhaps using Drizzle or Prisma.

I have had success deploying to Vercel by including sqlite generated from node-gtfs as part of the repo in a read-only fashion (following the baked-data pattern https://simonwillison.net/2021/Jul/28/baked-data/ )

Thanks ! So if I understand well, you have a server (or your local computer) where you're building your db, and then on Vercel you're downloading (through git or S3) a prepared version of your DB to be consumed without any writes.

In other words, no importGTFS on the edge platform ?
