Set NodeJS Options for Remote Instances

FlowFuse Device Agent v3.8.1 adds support for setting Node.js command line arguments for Remote Instances.

This allows things like:

• Setting the Node.js heap size for memory-intensive flows
• Enabling --use-openssl-ca (Linux) or --use-system-ca (Windows and macOS) to use private CA certificates

Node.js options can be configured in two ways:

1. Via the device agent command line

Use the --node-options argument. This argument may be specified multiple times:

bash flowfuse-device-agent -c /opt/flowfuse-device-agent/device.yml \ --node-options='--max_old_space_size=256' \ --node-options='--use-openssl-ca'

2. Via the device.yml file

Add a nodeOptions section:

yaml deviceId: xxxxxxx forgeURL: https://app.flowfuse.com token: xxxxxxxx credentialSecret: xxxxx nodeOptions: - '--max_old_space_size=256' - '--use-openssl-ca'
