Bit of a confusing name, when there is already an extremely popular mongodb node.js framework called Mongoose

Disagree with the downvote. Never used mongoose, nor am i a node developper, yet my first reaction was to wonder why a js db library evolved in an iot framework.

Seems to be the latter, fairly typical "its GPL unless you want to pay us for a different license"

There's actually a very good use case if you have sleeping children:

It's not on AWS but runs on a local raspberry pi, but my doorbell signals via MQTT that someone ringed. This makes my security camera take a picture and sends a push notification to a custom made iOS app which shows who's in front of the door on my apple watch. If I'm logged in my home wifi, I can even open the door with a button directly from this notification. I would argue that I'm not the only one who finds that useful.

> mJS - JavaScript engine for prototyping and C/C++ for production

I don't know much about it, but from the surface it seems that the problem is exactly the same? What is the benefit of prototyping in JS instead of Python? In the end, either you refactor everything purely in C, or you use both in your production system.

I see mJS does FFI to interface with other C routines. Why introduce a second language to your project? This seems like a huge overhead for no benefit (you're still expected to write C at some point). The language is only a subset of JS, so "not JS", so no ecosystem and new assumptions you have to redefine before getting serious with it?

Is it just me who thinks it's a bad idea? Would someone be able to explain the advantage of going in this direction?

I haven't checked what Mongoose does, but it's fairly common for embedded OS's to link the application and kernel together. IOW, using the GPL may force you to give the source code to your customers if they ask for it.
