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.

Server side validation
I also wrote this library, which makes things even more node/deno like: https://github.com/burggraf/supascript

Functions?
You can also check out my SupaScript extension here, which may give you access to other node libraries you may need: https://github.com/burggraf/SupaScript
-
Firebase and other options
And I write a majority of my functions using Javascript and even have access to a lot of npm libraries. (I wrote https://github.com/burggraf/SupaScript for this purpose).

Open source Firebase alternative (Supabase) raises $30M Series A
You should also look at my SupaScript repo on github. This is a wrapper on PLV8 that lets you write functions in Javascript with NodeJS and Deno-like functionality. It also makes it MUCH easier to work with JSON data and make HTTP calls to API providers. If you're comfortable with NodeJS, you'll find it pretty easy to write Postgres functions with this.

JSR: The JavaScript Registry
Unpkg serves whatever is published to NPM, and if it's a library intended for the browser, that often includes minified versions ready for use in script tags, for example, https://unpkg.com/[email protected]/mithril.min.js. Sometimes the default export is CJS (which has require() calls), in which case, you can usually use the browse url that I mentioned to see if there's another export you can use.
https://esm.sh/ is definitely a good option too if you're OK with modules.

Deno Cron
* Change my NPM imports to something that would work with Deno. The most straightforward thing to do was just change `import "foo"` to `import "npm:foo"`, but this felt hacky so eventually I used https://esm.sh, which worked for some packages but not others.
