SheetJS js-xlsx
📗 SheetJS Spreadsheet Data Toolkit -- New home https://git.sheetjs.com/SheetJS/sheetjs
Project mention: How to Convert Supplier CSVs to Shopify/Amazon/WooCommerce Without Uploading to a Server | dev.to | 2026-06-01The decision to process everything in the browser wasn't just about cost savings (zero server bills). It's a privacy feature: supplier inventory data, wholesale prices, and margin calculations never leave the user's machine. Technically, the app uses Papa Parse for CSV and SheetJS for XLSX, both loaded dynamically from CDN. The parsed rows are stored in a simple JavaScript array — no WebAssembly, no worker pool, just plain array operations that complete in under 50ms for typical supplier files.

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: Run SQLite in the Browser with sql.js: A Complete Guide from Install to CRUD | dev.to | 2026-03-08
sql.js is a browser solution. If you're in Node.js, use better-sqlite3 instead — it uses native bindings, runs significantly faster, has a cleaner API, and doesn't carry the 1.5 MB Wasm overhead.
