Top 23 JavaScript Client Projects

postgres
Postgres.js - The Fastest full featured PostgreSQL client for Node.js, Deno, Bun and CloudFlare (by porsager)
Bun provides native MySQL, SQlite, and Postgres drivers.
I'm not saying Node should support every db in existence but the ones I listed are critical infrastructure at this point.
When using Postgres in Node you either rely on the old pg which pulls 13 dependencies[1] or postgres[2] which is much better and has zero deps but mostly depends on a single guy.

Project mention: The Invisible Network Calls: Tracking fetch() and dns.promises in Node.js | dev.to | 2026-04-08
Then Node.js 18 introduced a global fetch() function. It looks like the browser Fetch API. It's convenient. It's modern. And it's backed by undici — a completely separate HTTP client that does NOT use http.request internally.
