Built micropython firmware including fadushin's webserver module UHTTPD into file.bin to flash to an ESP8266. So many js libraries around to make super fun user interfaces for your hardware. I included smoothie.js in the file WWW to try out...

Flash the compiled versionn onto your ESP8266 using esptool.py

esptool.py --port COM16 erase_flash

esptool.py --port COM16 --baud 460800 write_flash --flash_size=detect 0 C:/file.bin

Then use ampy or webrepl to move the www folder and files onto your board: https://learn.adafruit.com/micropython-basics-load-files-and-run-code/file-operations

ampy --port COM16 put C:/esp/www

Finally you can use a serial monitor, webrepl, puTTy or the like to start typing python commands....

>>> import uhttpd

>>> import uhttpd.file_handler

>>> server = uhttpd.Server([('/', uhttpd.file_handler.Handler('/www'))])

>>> server.run()
