Speed Stars

Yes, in development Rails compiles everything listed in manifest.js, which can feel slow — it’s by design for debugging, but you can tweak configs or split manifests to speed things up.

It depends on the platform you choose. If you just want to explore Rails broadly, a subscription might give you more value in the short term. If you find a single course that looks really solid, a one-time purchase can be more cost-effective.

Using RethinkDB changefeeds with Rails + Server-Sent Events is a solid approach for keeping your widget data live without requiring browser refreshes—perfect for a fast-moving boxscore. While there aren’t many Rails-specific tutorials pairing RethinkDB + SSE, you can adapt examples of RethinkDB changefeeds with Node/Express pretty easily, since the concept is the same: listen to DB changes → push them via SSE.
