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.

Notes: Advanced Node.js Concepts by Stephen Grider
In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.

Rest server for embedded system
Some useful libraries include nghttp2 for HTTP/2 and llhttp for HTTP/1.1. Both are network stack and TLS implementation agnostic.
-
Does nodejs intercept http request natively or does it use something to understand http request like wsgi in python ?
There is a HTTP parser directly bundled in node (https://github.com/nodejs/llhttp)
-
Fetch API has landed into Node.js
Those wasm blobs are Node's own llhttp https://github.com/nodejs/llhttp in wasm to speed up HTTP parsing.
The question is totally legitimate but please assume core doesn't make "load random binary" level kind of goofs :)

Book recommendations for Backend development concepts for a beginner
For HTTP, you have to look at HTTP parser. For example, https://github.com/nodejs/llhttp is used in NodeJS.

The history and reasons behind CORS, and how to use it
Whoa, I didn't know that! But yeah, it seems like https://github.com/nodejs/http-parser is based on nginx. It now uses https://github.com/nodejs/llhttp but has some of the same legacy.
On the other hand, deno's HTTP stuff is built on top of Hyper, a Rust library https://github.com/hyperium/hyper

Show HN: Micro HTTP server in 22 lines of C
No, parsing HTTP/1.x is a nightmare and definitely not simple. It wasn't even particularly well defined until 2014 when the original RFCs were modernized, and even now there are bugs reported in HTTP parsers all the time.
Node.js came out in 2009, a full ten years after HTTP/1.1 (RFC 2068) and it's original http-parser is full-on spaghetti code, doesn't conform to the RFCs for performance reasons, and is considered unmaintainable by the author of it's replacement[0]

GitHub Engineering: When MTLS Is Done Wrong
mTLS has warts when used cross-origin. Fetch spec says that pre-flight requests mustn't include client certificates[1], so as a consequence servers behind mTLS authenticated proxy won't get a chance to reply to those pre-flight. Yet for non-preflighted requests it's fine to include client certificates..

Node.js fetch() vs. Deno fetch(): Implementation details...
I've been testing full duplex streaming from and to the browser using fetch() in a Native Messaging host. (No browser currently support full duplex streaming even though HTTP/2 does, see Fetch body streams are not full duplex #1254).
-
How do I detect requests initiated by the new fetch standard? How should I detect an AJAX request in general?
Most js libraries use XMLHttpRequest and so provide HTTP_X_REQUESTED_WITH: XMLHttpRequest, but neither Chrome's implementation nor Github's polyfill of the new fetch uses a similar header. So how can one detect that the request is AJAX?

Server Sent Events
Any resource of significance should be given a URI. https://www.w3.org/DesignIssues/Axioms.html#uri
Or alternatively,
> Cool URLs don't change (implicitly, cool things have URLs, see above). https://www.w3.org/Provider/Style/URI
The advantage would be so high. It'd become a standard way to assert a resource, to make known a fact, that would be viable across systems. Instead of pushing to a chat app an anonymous chat message in a room, the server could assert a /room/42/msg/c0f3 resource, could identify universally what it is it's sending.
We have come glancingly close to getting such a thing so many times. The HyBi mailing list that begat websockets had a number of alternate more resourceful ideas floating around such as a BEEP protocol that allowed patterns beyond request/response of resources. The browser actually implements an internal protocol that uses HTTP2/push to send resourceful messages... Even though http2/push was de-implemented for webserving in general, and even though ability to hear push events was never implemented (oft requested).
The best we have today is to stream json-ls events, which have an @id property identifying them. But developers would have to snoop these events, and store them in a service worker, to make them actually accessible as http resources.
I continue to hold hope eventually we'll get better at using urls to send data, to assert new things happening... But it's been nearly 30 years of me hoping, and with some fleeting exceptions the browser teams have seemed disinterested in making urls cool, in spite of a number of requests. https://github.com/whatwg/fetch/issues/65 was an old request. https://github.com/whatwg/fetch/issues/607 had some steam in making it happen.

My experience being blocked by Google Safe Browsing
Port 10080 is blocked on most browsers[0] per the WhatWG "bad ports" list[1]. That particular port was added to the list due to the Slipstream attack[2] that made the news a few years ago[3].
You don't have to switch to a browser that ignores standard security mitigations. Just pick a different port for your service.
[0] I just tested Chrome, Firefox, and Safari.
