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.

PostgREST – Serve a RESTful API from Any Postgres Database
You can use a library like https://github.com/agentultra/postgresql-replicant or similar to hook in a data plane and use PostgREST as a data plane.
Your business logic works on the event stream that comes from the WAL.

backend.sql and frontend.js = ♥
I wrote postgresql-replicant [0] in order to do this. It’s not a novel idea. It lets you read the logical replication stream.
On top of this library you can do all sorts of things: replicate data to Kafka or SQS, write a web socket server to publish changes to clients, etc.

Ask HN: What are some tools / libraries you built yourself?
https://github.com/agentultra/postgresql-replicant — stream delta changes from a PostgreSQL database. Not a novel concept or implementation but this library doesn’t exist in Haskell and that’s a shame because Haskell has lots of great libraries for working with streams.
https://github.com/agent ultra/DataVersion — type-directed data migration library. I needed to migrate some data in a document database that had no schema with years of data in it to a format that had a schema. I leveraged some other stuff to achieve it but this library was a key piece to being confident that the transformations were correct and complete. Migrated the database and backfill it with a Lambda function using this library.
Those are just the most recent ones.

Haskell good for general use?
On my stream at https://twitch.tv/agentultra I've been working on a library to stream changes out of a PostgreSQL database. We've had to figure out how to use low-level libpq bindings, concurrency primitives, serializing and deserializing binary messages, etc. You can find the library here: https://github.com/agentultra/postgresql-replicant

[Announce] postgresql-replicant-0.1.0.0-candidate: streaming PostgreSQL changes
You can star the repo and report issues at: https://github.com/agentultra/postgresql-replicant -- new contributors are welcome! I'm still working out a contribution guide, it's still super early on the project. I can be found here and on the FP Slack (https://fpchat-invite.herokuapp.com/) and on the FP Zulip (https://funprog.zulipchat.com)

Getting Started with Axum - Rust's Most Popular Framework
You can also use HTML templating with crates like askama, tera and maud! This can be combined with the power of lightweight JavaScript libraries like htmx to speed up time to production. You can read more about this on our other article about using HTMX with Rust which you can find here.. We also collaborated with Stefan Baumgartner on an article for serving HTML with Askama!

Full-stack authentication system using rust (actix-web) and sveltekit
An authentication system is an integral part of modern applications. It's so important that almost all modern applications have some sort of it. Because of their critical nature, such systems should be secure and should follow OWAP®'s recommendations on web security and password hashing as well as storage to prevent attacks such as Preimage and Dictionary attacks (common to SHA algorithms). To demonstrate some of the recommendations, we'll be building a robust session-based authentication system in Rust and a complementary frontend application. For this article series, we'll be using Rust's actix-web and some awesome crates for the backend service. SvelteKit will be used for the frontend. It should be noted however that what we'll be building is largely framework agnostic. As a result, you can decide to opt for axum, rocket, warp or any other rust's web framework for the backend and react, vue or any other javascript framework for the frontend. You can even use rust's yew, seed or some templating engines such as MiniJinja or tera at the frontend. It's entirely up to you. Our focus will be more on the concepts.

Show HN: Robyn – the fastest Python web framework written in Rust
Or Flask!
My guess is that "fastest" refers to the request-response loop.
I'd be interested in knowing how fast it is once you tack your favourite template rendering engine on top.
It would be nice if it supported Tera, the Rust template engine that is inspired by Jinja2:

Help with warp routes
As you might've noticed I have a static www folder with all my files. If I go to /, /login, /register I want to respond with my templated HTML. If the browser asks for another file, such as index.js or something.png I want to serve it from the static folder. I someone wants to access the raw template HTML, such as index.html I want to response with a 404 message.
