Has anyone embedded a web-UI into a C++ project?
Here's what I did: - I bought a theme that I liked, and used mstch as template engine (matched the theme's template format) - Imported rapidjson for parsing JSON, and used mstch for generating JSON (the JSON I generate is simple enough that I can do this) - Wrote an HTTP handler class for each page that handles the GET and POST requests, generating HTML or JSON depending on the request

Is there a good cross-platform (Windows / Linux) C or C++ library for file I/O?
And documentation in most cases is more user-friendly if you will use something like MkDocs(based on Markdown), example http://rapidjson.org/

DAW JSON Link v3, a JSON serialization/deserialization library, is released
It seems not super widely used compared to other famous libraries like RapidJSON, nlohmann-json, or simdjson. But it seems the author is very active in developing this project which can mitigate this "lack of community" issue.

Is cpp a good language for reading and writing large quantities of JSON files as quickly as possible?
have a look at rapidjson for a a nice simple json framework https://rapidjson.org/ I use it and it's quite fast and as good as anything I used in python.

What JSON library do you suggest?
So I just cloned https://github.com/Tencent/rapidjson to see what is the current status. At compile time they check if the C++ compiler supports the "noexcept" keyword, and if so they define RAPIDJSON_NOEXCEPT to be "noexcept". Throughout the implementation, RAPIDJSON_NOEXCEPT is added to quite a few function declarations (about a hundred of them).

How and where I can learn about Web sockets, APIs, Wrappers to connect with my C++ code?
RapidJSON is also excellent, like fantastic when performance matters. Not sure there's a much faster JSON implementation anywhere, and I've written my own SAX-style parser as a fun, hobby project for C++.
- Can anyone point me to an open-source project that correctly uses allocators?

How to parse two int values per line from a char* array from memory map
I loaded a 7Gb file into a memory map using the mio header file. The mmap variable is a char* array. I used a short file since this is my first time attempting a memory mapped file. This is the text2.txt file

Using mio header file to read in large file
I am using this mio header file and attempting to read in a 7GB file. This is taking a long time to execute so I stop the execution. I am reading in a small file just to test this out.
