installing node-opcua as a node package
$ mkdir mytest
$ cd mytest
$ npm init
$ npm install node-opcua --unsafe-perms
$ # create your first app.js file!
installing node-opcua samples as a node package
$ mkdir myserver
$ cd myserver
$ npm init
$ npm install node-opcua-samples --unsafe-perms
$ ./node_modules/.bin/simple_server
or
$ ./node_modules/.bin/simple_client -e "opc.tcp://opcserver.mAutomation.net:4841" -n="ns=1;s=EVR2.system.RTC_SEC"
or
$ ./node_modules/.bin/simple_client -e "opc.tcp://opcuademo.sterfive.com:26543"
