Web Scraping with C++
It uses libcurl and gumbo (https://github.com/google/gumbo-parser). Gumbo is apparently written in pure C99 (interestingly Curl is written in the even older C89 standard). Will've been more amusing if article was written considering that and used C99.

The computers are fast, but you don't know it
> A standards compliant HTML5 parser is at the bare minimum millions of lines of code.
But https://github.com/google/gumbo-parser is only 34K lines?

Markup Language Operations in Nim to extract and remove el
oops... I saw a markup parser and automatically thought XML, but you are right! HTML is actually a whole different beast!
As it turns out, seems like nim also has an html parser [1], but I'm guessing something like Google's gumbo [2] could be more reliable, but you would have to write bindings for nim.

What second language to learn after Python?
Well, regarding HTML5, what I've found was libxml (does not support tag-soup HTML5), https://github.com/lexbor/lexbor, for which I was unable to find good documentation ( see https://lexbor.com/docs/lexbor/#dom), Apache Xerces (appears to not support tag-soup HTML5 as well), and Gumbo, which does not appear to be active and to support selectors and XPath (although there are libraries that add that).
-
Does anyone know of an HTML parser written in C++ that has Node.js interface?
I haven't used any of them, but there's a few wrappers available for Gumbo.

What C++ library do you wish existed but hasn’t been created yet?
This one might fit the bill https://github.com/libcpr/cpr

How to convert libcurl to C++?
There is also the cpr package which should offer a more c++ focussed interface for curl.

Trying to use libcpr, linking errors - newbie...
So I'm very new to C++ and I'm trying to write a C++ version of a tool that I put together in Python. I'm trying to use libcpr for all my HTTP needs. I've spent the day trying to get it set up and working, but I'm getting a bunch of linking errors when I try to run. I really don't know if I did the building of it correctly, I'm trying to use Visual Studio Community 2022 and the Usage section of their docs talks about CMake and a couple package manager methods.

Standardise a C++ build tool and package manager?
I think vcpkg manifests have solved a really key portion of the "please give me these libraries" problem. Couple lines in a json file, pass CMake to your vcpkg toolchain script path and triplet, and you're pretty much done with dependencies. I actually used it for a project with libcpr/cpr and a couple other popular libraries, and I was shocked at how painless it was to get up and running with some web request stuff.

What are some cool modern libraries you enjoy using?
Libraries like nlohmann's json, cpr, fmt are prime examples of what I'm seeking. Any suggestions?

I'm getting a 422 Validation Failed from Github API. Only when making a request with the Cpr library.
Basically specifying the language and the repo, and it does work when the request is made from postman or from the browser. However, when using https://github.com/libcpr/cpr, I'm getting the following response:
