Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Testcontainers
If your project uses Nix, checkout services-flake for running services via Nix.
https://github.com/juspay/services-flake
We actually do this in Nammayatri, an OSS project providing "Uber" for autos in India.
https://github.com/nammayatri/nammayatri
There is a services-flake module allowing you to spin the entire nammayatri stack (including postgres, redis, etc.) using a flake app. Similarly, there's one for running load test, which is also run in Jenkins CI.

Show HN: I open-sourced the in-memory PostgreSQL I built at work for E2E tests
Hey HN! For a few months, I've been building pgmock at work for our E2E and unit test suite. It emulates Postgres in WebAssembly and has full feature parity with production databases.
The cool thing about it is that you don't need any external processes or proxies. If your platform can run WASM (Node.js, browser, etc.), it can probably run pgmock. Creating a new database with mock data is as simple as creating a JavaScript object.
It's a bit different from the amazing pglite [1] (which inspired me to open-source pgmock in the first place). While pgmock runs an x86 emulator, pglite compiles a Postgres fork to native WASM directly and is hence much faster and more lightweight. However, it only supports single-user mode and a select few extensions, so you can't connect to it with normal Postgres clients (which is quite crucial for E2E testing).
Theoretically, it could be modified to run any Docker image on WebAssembly platforms. Anything specific you'd like to see?
Happy hacking!

Soul: A SQLite REST and Realtime Server
I've found postgres via docker to be fine for dev and testing, but there are various epheremal postgres scripts, plus this could be promising for node stuff https://github.com/electric-sql/pglite if it works out. I'd imagine if this does work out we'll see the same kind of builds for other runtimes as well (like python)

The Cell Programming Language
> Use SQLite for everything, or Postgres if you outgrow it.
Or both! ElectricSQL syncs front end SQLlite back to server side postgres. And they just rebuilt postgres on pure WASM (https://github.com/electric-sql/pglite). All ties together with a CRDT.
I'm not affiliated, but just think it's just cool to imagine calls to front end sqllite as the be-all-end-all.
