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.

Jacobin: Minimal JVM written in Go and capable of running Java 17 classes
Ummm, excuse me, but where the f&$k has this been hiding? I’ve been looking for ways to extend my go applications with scripting support. I started with Lua (worked ) then Python (worked but hacky) then javascript using otto [1]. However it lacks ES6 support so having pretty OOP js code is a non-starter. I would love to have Java as a runtime that can be executed from goroutines.

Running a Js file inside Go
Either call a JavaScript interpreter like node with exec.Command and read its stdout, or use a pure Go JavaScript interpreter like goja or otto.

Suggestion for a dynamic Struct Validation Rules
Otto https://github.com/robertkrimen/otto Seems interesting. It lets me call Go functions from inside JS as well as return results. The fncs pattern reminds me a bit of how the template engine works.

Wazero: The zero dependency WebAssembly runtime for Go developers
> why host other languages
Here's an example:
I recently finished building https://subzo.com.au which allows customizing and ordering 3D models. The way the model's cost, volume and other attributes are calculated needs to be done both on the frontend (for speed) and on the backend (to validate). Backend is in Go and we can't practically run Go in the browser. So instead, I wrote the calculation snippets in JavaScript (which runs natively in the browser) and ran them on the backend on a JavaScript VM library written in Go [1].

Choosing scripting extension - need advice
Googling suggests https://github.com/robertkrimen/otto which allows scripting in javascript for golang projects. This would be definitely enough, but in some way it may be a bit overkill - and scripts supporter shall need some knowledge of javascript which is not always straightforward :)

I write my own web desktop OS for 3 years and this is what it looks like now
It doesn't make sense to ask the user (aka me) to change the code every time I want to modify any web apps right? So I decided to split the webapps into two parts. WebApps are those only require basic permissions and do not interact with the host OS. They will be run inside a sandbox created using ECMA5 VM called Otto. The other type is called Subservice, in which it will need extra permission to interact with the OS and require higher level of access to the backend file system.

SSR React in Go
Firstly, I used rogchap/v8go to execute JavaScript in a Go environment. I listed other options below.

I built a local Laravel dev environment that doesn't require PHP at all
Now the only issue I see is that someone who can't be bothered to install PHP and composer will probably not want to install node and npm either. If you could somehow run WASM inside an executable file (maybe something written in Go with https://github.com/rogchap/v8go ? Or an Electron App ?), all you'd need to do is download the executable file on any computer and double click it to start serving a Laravel project.

Show HN: A Full-Stack Web Framework Written in Go
I only browsed for a wee bit, so take this with some salt, but it _looks_ like the framework is running a JS VM isolate alongside the Go server struct[1], which gets called with whatever script file is being rendered. Since it looks like the render files are, at least in the case of Svelte, individually compiled JS files that are SSR rendered via the V8 isolate, I _believe_ you're correct that there is no CSR (though there might still be JS-hydrated code if the Svelte component included something involving an interactive component).
I think the idea is to ingest a JS "template" and spit out the rendered HTML+JS, kind of like traditional SSR templates, but it could be possible to shoe-horn in an entire client-side router that gets initialized as a DOM object somewhere.

Plenti — a Svelte SSG for people that don’t like web maintenance bullsh#t
Plenti is a simple open source Static Site Generator (SSG) with a Go backend and Svelte frontend. Jim picked Golang because it is simple, quick and has the ability to generate a binary that can be run on any machine; and Svelte, well, for one, “Svelte is so hot right now” and also because of the power it gives developers to write simple HTML and CSS to create websites. Merging these two technologies was not an easy task, but with V8Go binding the two together, it’s a marriage that works.
