Project mention: Ask HN: How Can I Make My Front End React to Database Changes in Real-Time? | news.ycombinator.com | 2024-04-17

I'm interested in this problem also!
I think there is a large overlap with projects that market/focus on offline-first experiences.
AFAIK this problem can be solved by:
1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take!

Project mention: Rust GraphQL APIs for NodeJS Developers: Introduction | dev.to | 2024-02-08

In my usual NodeJS tech stack, which includes GraphQL, NestJS, SQL (predominantly PostgreSQL with MikroORM), I encountered these limitations. To overcome them, I've developed a new stack utilizing Rust, which still offers some ease of development:

slonik

71 4,381 9.2 TypeScript

A Node.js PostgreSQL client with runtime and build time type safety, and composable SQL.

Project mention: Sneakiest development trap: making easy easier... | dev.to | 2024-01-04

And sometimes invest instead in learning a technology rather than hide it: for example slonik encourages you to write normal SQL queries by making SQL templating easier and safer. In turn, your IDE would be able to understand those queries and give you support based on the database schemas you actually have.
