node-opcua is an implementation of an OPC UA stack fully written in Typescript for NodeJS.
Node-opcua is the OPC-UA stack running on NodeJS.
Why NodeJS ?
Because nodeJs is a great framework to design asynchronous applications.
$ mkdir mytest
$ cd mytest
$ npm init
$ npm install node-opcua --unsafe-perms
$ # create your first app.js file!
$ mkdir myserver
$ cd myserver
$ npm init
$ npm install node-opcua-samples --unsafe-perms
$ ./node_modules/.bin/simple_serveror
$ ./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" - nodejs version 14 or above
