@slightlyoff @kellan one more thing to add is that according to people at Google, poor INP and LCP often go together.

Thanks to RSC, SQL in JS is suddenly a hot topic. In this context it's worthwhile to shout-out @RemultJs, a "CRUD framework for fullstack TypeScript". Check it out! https://remult.dev/

I know it's a hot topic, but it's Friday so let's talk about why, if you choose to write SQL by hand, the use of a "sql tagged template" is good for security:
