FSBrowserNG | Full autocontained async web server

FSBrowserNG is a C++ library typically used in Internet of Things (IoT) applications. FSBrowserNG has no bugs, it has no vulnerabilities and it has low support. However FSBrowserNG has a Non-SPDX License. You can download it from GitHub.

I wanted to add a standard environment for all my ESP8266 based projects to be able to configure them via web browser to avoid code editing when I need to change some settings like SSID, password, etc. I found John Lassen's WebConfig project to almost fit my needs. It uses a simple but powerful web interface with dynamic data using microAJAX. I've added some dynamic data using Links2004's WebSockets library. So, I tried to fork it. Original WebConfig project stores web pages on PROGMEM, but I was recently using SPIFFS on ESP8266 and I think it is a good way to store web content. I found I was not the first to think this when I noticed about FSBrowser example in ESP8266WebServer library. This example code has a great bonus: a text editor (based on ACE) with syntax highligth that can be used to edit html on board directly. I found a bug on it (already sent to esp8266/Arduino repository) and, when fixed, noticed how usefull this editor is. My code is a fork of both projects, and has become a start framework for my future projects. Finally i've refactored code to use it as a library, so it is easier to integrate it in a project. See this example to check that only 3 lines are necessary to use it. I only have to add more HTML data and some funtions to show dynamic data in order to adapt it to any other task. It has integrated NTP syncronization based on my own NTPClient library, that can be configured via this Web interface too. Configuration is stored on SPIFFS too, in a JSON file. So, it recovers config during boot. Implemented OTA Update with Arduino IDE and Web interface. Web access can be protected with Basic HTTP Authentication. I use a library called ESPAsyncWebServer. It is much faster than standard ESP8266WebServer library due to its async design.
