Node-RED

The Node-RED project has a number of components:

• Node-RED, the visual designer tool.

• Node-RED Dashboard, a dashboard user interface for Node-RED.
• Node generator, a command-line tool to generate Node-RED node modules from several sources, including OpenAPI documents and a function node's source.
• Node-RED Command Line Tool, a command-line tool that allows for remotely administering a Node-RED instance.

A Node-RED flow describes the connection and sequencing of various input, output, and processing nodes within the Node-RED platform. Each node within a flow performs a unique and specific task. When data is transmitted to a node, the node processes it according to its designated function, before passing it on to the subsequent node in the flow. This system allows for the controlled execution and regulation of a wide range of operations. Node-RED flows represent the primary visual programming mechanism of the tool.

The 2023 Node-RED Community Survey{{Cite web |title=2023 Node-RED Community Survey : Node-RED |url=https://nodered.org/about/community/survey/2023/ |access-date=2023-07-02 |website=nodered.org}} provided insights into the usage patterns, preferences, and feedback from 780 individuals who are part of the Node-RED community. The survey, conducted in March 2023, revealed that Node-RED's usage extends beyond DIY home automation, with a trend towards professional use in a variety of industries. Over half of the respondents had been using Node-RED for over two years, indicating a well-established community. The most common messaging technologies used in conjunction with Node-RED are MQTT and HTTP, while InfluxDB emerged as the most popular database within the community. The survey also shed light on perceived barriers to adoption, pointing towards the perception of Node-RED as a proof of concept tool and the lack of certain key features. Despite these challenges, the survey highlighted a high level of satisfaction within the community, with over two-thirds of respondents rating Node-RED a 5 out of 5.
