![]() ![]() Node-RED uses flows_.json as the default flows file. If the Projects feature is enabled, this identifies which project should be started. If the Projects feature is not enabled, this sets the flow file you want to work with. When you deploy your changes, the flows are then started. This allows you to open the flows in the editor and make changes without the flows running. ![]() Starts Node-RED without starting the flows. Sets the TCP port the runtime listens on. Start by updating the package repository with the command: sudo apt update 2. Node-RED can be started using the command node-red. Option 1: Update Node.js with NVM (Node Version Manager) The best way to upgrade Node.js is with NVM, a practical tool for managing multiple Node.js versions. This by providing the flow file name as argument to the node-red command.
