Node-RED is an open-source visual programming tool for wiring together hardware devices, APIs, and online services in a flow-based manner. It provides a browser-based flow editor that allows users to create and deploy event-driven applications by connecting pre-built nodes (blocks of functionality) to create a workflow.

  1. Flow-Based Programming: Visual creation of workflows using a graphical interface.

  2. Extensibility: Large ecosystem of pre-built nodes for integrating with devices, services, and protocols.

  3. Event-Driven Architecture: Support for reacting to incoming events and triggering actions.

  4. Integration: Seamless integration with hardware devices, APIs, databases, and cloud services.

Before learning Node-RED, it's beneficial to have the following skills:

  1. Basic Programming: Understanding of programming concepts like variables, control structures, and functions.

  2. Web Technologies: Familiarity with HTML, CSS, and JavaScript for creating custom user interfaces.

  3. Networking: Understanding of networking fundamentals such as TCP/IP, HTTP, and REST APIs.

  4. IoT Concepts: Knowledge of Internet of Things (IoT) concepts and protocols like MQTT, Modbus, and Zigbee.

By learning Node-RED, you gain the following skills:

  1. Flow-Based Programming: Ability to create visual workflows using a graphical interface.

  2. Integration: Skill in integrating hardware devices, APIs, databases, and online services.

  3. Event-Driven Development: Understanding of event-driven programming concepts to react to incoming events.

  4. Dashboard Creation: Proficiency in building custom user interfaces to visualize data and interact with applications.
