You can run the full example:

opkg update
opkg install lua luasocket luasec
# openssl is needed for wget to handle https://
opkg install wget openssl-util libustream-wolfssl
# Get blynk-library-lua from github
cd /root
wget --no-check-certificate -qO- https://github.com/vshymanskyy/blynk-library-lua/archive/v0.2.0.tar.gz | tar xvz
cd blynk-library-lua-0.2.0
# Run it

It is very easy to get it running on NodeMCU (or any other ESP8266

blynk
object is global, so you can call it from the interactive console:
blynk:virtualWrite(1, tmr.time())
sudo apt-get install lua5.3 lua-sec lua-socket
The Timer
is included for demonstration purposes.
Here are also some handy functions:
local function millis()
return math.floor(socket.gettime()*1000)
end
local function delay(msec)
return socket.sleep(msec/1000)
end
