Any list of most used IoT libraries for ESP boards?

Hello everyone, I'm developing an IDE for Arduino, currently I'm creating a IoT resources interface. My IDE already compiles and upload codes to the ESP32 and NodeMCU-12E boards, but I have never used them in my projects. Could anyone tell me what the most used IoT-focused libraries in this boards? Getting his names, i will add them on my IDE, with a real-time code description. Txs!

GitHub has a really nice search system that allows you to sort the results by number of stars, which is a reasonable indicator of popularity. The trick would be to get your search terms right. I suspect quite a few popular libraries that you would consider "IoT-focused" don't even use the term "IoT" or "Internet of things".
