@vhymanskyy, Its not good idea, because this lib support AT v0.22 version up to SDK 0.9.6. Latest SDK 1.0.1 requires ESP8266 modules with 1Mb flash and more, and have smallest free RAM. This lib, also, do not have commit for 2 last months.
NodeMCU have very small heap size with SDK 1.0.0 and above and stop develop on SDK 0.9.6 now.
Good way, IMHO, Arduino IDE. Users can easy update ESP8266 firmware and can customize it.
Also, you can see many commits and pull requests every day from many users on Arduino IDE repo on github
