Step 3 – building the OPC UA Connector

To build the OPC UA Connector we need to download the Node.js AWS Greengrass SDK, the AWS OPC UA Connector, build our OPC UA Lambda, and deploy it to the cloud.

Check the official documentation at https://docs.aws.amazon.com/greengrass/latest/developerguide/opcua.html . Unfortunately, at the time of writing, there is a small bug reported in the documentation.

To do this, follow these steps:

1. From GitHub, fork the GitHub repository at https://github.com/aws-samples/aws-greengrass-samples.git on the local aws-greengrass-home folder and install the packages:

$ git clone https://github.com/aws-samples/aws-greengrass-samples.git$ cd aws-greengrass-samples/greengrass-opcua-adapter-nodejs$ npm install
