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.

Critique of Lazy Sequences in Clojure
Clojure's lazy sequences by default are wonderful ergonomically, but it provides many ways to use strict evaluation if you want to. They aren't really a hassle either. I've been doing Clojure for the last few years and have a few grievances, but overall it's the most coherent, well thought out language I've used and I can't recommend it enough.
There is the issue of startup time with the JVM, but you can also do AOT compilation now so that really isn't a problem. Here are some other cool projects to look at if you're interested:

[ANN] Malli 0.11.0 is out - a data-driven data specification library for Clojure/Script
BREAKING: walking a :schema passes children instead of [id] to the walker function #884
-
Generic functions, a newbie question
When you get to larger, more complex validations, I'd recommend checking out Malli or Spec.
-
Any resources for "current best practices and learnings?"
for specs, you can try malli - feels pretty well supported and full featured: https://github.com/metosin/malli (i'm not 100% sure how popular it is for others, but I use it on my personal projects)
- Single-file scripts that download their dependencies

Have you tried malli: Data-driven Schemas for Clojure/Script?
-
Clojure from a Schemer's perspective
All that being said, I particularly use malli and I don't find anything to complain about. There is a very nice and sound ecosystem being built around it (malli-ts is one of my contributions to it, but still in early development stages). I highly recommend reading its README, very informative stuff.

Clojure 15th Anniversary: A Retrospective
Any large codebase can be broken up into small isolated components that can be reasoned about independently. This is how you structure Clojure projects if you want them to be maintainable. Clojure inherently encourages doing this by defaulting to immutability. The contract between components is the data being passed to the component and returned by it. Using Malli schemas at the edges of the components is a typical approach to documenting their APIs https://github.com/metosin/malli
I see the fact that people often end up creating large and tightly coupled monolithic codebases in static languages as a negative aspect of static typing. Such codebases are difficult to reason about even if you have guarantees that the types align. Ultimately, you need to understand the relationships in code, and how they relate to business logic. The more coupling an application has the harder it becomes to reason about it as a whole.
Ideally, I think applications should be structured as a bunch of Lego blocks that can be composed together. Each component should encapsulate some functionality, and then the flow of the business logic should bubble up to the top and expressed in how these components are chained together.

Worrying comment from HN on Building a Startup on Clojure
Uhhh spec has existed for a long time and before that, schema Nowadays we also have the excellent malli. If his codebase is full of functions where the shape of the data isn’t obvious, isn’t documented and isn’t specified in a specific/schema, that’s on him and his bad coding practices and really no different from passing data in other dynamic languages. A class by itself (without additional effort) only gives you field names.

Riff: A “mycelium-clj” for the Clojure ecosystem?
I definitely believe Clojure needs a rails. Not only will it help beginners get started, if it can help people get started faster and build fast like Django and rails do, I think it'll help more with adoption.
Biff and fulcro seems like they have a shot at this

[ANN] London Clojurians Talk: Why you need Fulcro, the web framework to build apps better, faster (by Jakub Holý)
Fulcro (https://github.com/fulcrologic/fulcro) is my web framework of choice whenever I need to create any non-trivial web application thanks to its productivity. Its overarching design goal is sustainable development speed as time goes and code grows and it really shows up. It is developer friendly, with minimal boilerplate, and features you need for any serious application. And it is surprisingly flexible. Fulcro is based on a few simple ideas that combine powerfully to produce a multitude of capabilities, including its Rapid Application Development "add-on". Some people find Fulcro complicated and scary - but it doesn't need to be. Stop choosing "simpler" web frameworks - and ending up implementing half of Fulcro with much more effort and verbosity and much less value. I will present the minimalist way of learning Fulcro with its three corner stones and explain Fulcro's building blocks. After this talk, you will understand the design and value of Fulcro, be motivated to learn it, and equipped to do so quickly.

Electric Clojure second batch of tutorials - multiplayer chat, backpressure, component lifecycle, todolist
I am curious how this compares to Fulcro both from a conceptual and a usage perspective. Which advantages does this offer over Fulcro?

Libraries that join front and back end?
Fulcro has a complete "story" for data-driven UIs and backends. https://github.com/fulcrologic/fulcro

Looking for an example of server-side rendering and client-side rendering with Clojure(script)
We do that via Fulcro: render the first frame in CLJ on JVM, then continue with CLJS in browser. The code is a bit dirty and probably won’t tell you much (because I can’t share the whole app), but you can definitely do that.
What are some alternatives?
