can i get the complete list of nodes with input and output properties in excel?

Welcome to the forum @itxDataScientist

What do you mean by input and output properties?

If you mean that you want a different way of analysing message flows, then you would have to import Node-RED's flow file - probably using PowerQuery to reformat it to tabular data.

But I doubt it will tell you what you want. That's because, in general, nodes don't much care about what is up-/down-stream of them.

But, as Colin has suggested, we need to know a lot more about what you are trying to achieve before being able to give you further help.

do you mean like all the repository of node-red nodes/ contrib-nodes available with their functions/uses as a list in an excel spreadsheet ?

exactly and with that configurable ones separate, check the pic i shared

I have never seen a screen like that, exactly where are you seeing that?

8

actually i want to have a spreadsheet all available nodes
(with the details as shown in the above table)

It isn't impossible. But it will be incredibly hard I believe.

You will have to start by analysing each node in your environment looking for all of the node's settings. That would get you the node name and configurable properties - but only using their internal names. You can get all that by analysing your flows.json file.

To get friendly names, I think you would have to analyse each nodes Editor HTML for the setting and then work back to get the label. That would be time consuming, hard and fragile.

As for the input and output ports. Most nodes do no add meaningful port descriptions and generally the only place to look would be the help sidebar (more editor HTML) and even then, not all nodes will describe their inputs and outputs in the same way.

Personally, I do now add port descriptions to my nodes and I know a few other people do as well. But certainly not all. Especially older nodes.

See what Grok3 said

Node-RED is a powerful flow-based programming tool that comes with a set of core nodes included by default in its runtime, maintained by the Node-RED development team. Additionally, there are numerous contrib (contributed) nodes created by the community and published as npm packages, extending Node-RED's functionality. Since the list of contrib nodes is vast and constantly growing (with thousands available in the Node-RED Library), I’ll provide a comprehensive overview of the core nodes and a summarized approach to the contrib nodes, as listing every single one exhaustively isn’t feasible here.

Core Nodes in Node-RED

The core nodes are the default set provided with a standard Node-RED installation. As of February 21, 2025 (with my knowledge continuously updated), these are organized into categories in the Node-RED editor palette. Below is a list based on the standard core nodes available in the latest stable release (up to my knowledge base):

Input Nodes

  1. Inject - Manually or automatically triggers a flow with a defined payload (e.g., timestamp, string, JSON).

  2. MQTT In - Subscribes to messages from an MQTT broker.

  3. HTTP In - Creates an HTTP endpoint to receive HTTP requests.

  4. WebSocket In - Listens for messages from a WebSocket connection.

  5. TCP In - Receives data from a TCP port.

  6. UDP In - Receives UDP packets.

Output Nodes

  1. Debug - Outputs messages to the debug sidebar or console.

  2. MQTT Out - Publishes messages to an MQTT broker.

  3. HTTP Response - Sends an HTTP response (paired with HTTP In).

  4. WebSocket Out - Sends messages to a WebSocket client.

  5. TCP Out - Sends data to a TCP connection.

  6. UDP Out - Sends UDP packets.

Function Nodes

  1. Function - Executes custom JavaScript code to process messages.

  2. Template - Generates text using Mustache templating based on message properties.

  3. Change - Modifies message properties or context (set, change, delete, move).

  4. Switch - Routes messages based on rules (e.g., payload value, JSONata expressions).

  5. Range - Scales or maps numeric values within a range.

  6. Delay - Delays messages or rate-limits them.

  7. Trigger - Sends a message after a delay or on specific conditions.

  8. Exec - Runs a system command and captures its output.

Sequence Nodes

  1. Split - Splits a message (e.g., array, string) into multiple messages.

  2. Join - Combines multiple messages into a single message (e.g., array, object).

  3. Sort - Sorts an array in the message payload.

  4. Batch - Groups messages into batches based on count or time.

Parser Nodes

  1. CSV - Converts between CSV strings and JavaScript objects/arrays.

  2. HTML - Extracts data from HTML using CSS selectors.

  3. JSON - Parses or stringifies JSON data.

  4. XML - Converts between XML strings and JavaScript objects.

  5. YAML - Converts between YAML strings and JavaScript objects.

Storage Nodes

  1. File In - Reads content from a file.

  2. File - Writes or appends content to a file.

Network Nodes

  1. HTTP Request - Makes an HTTP request to a URL and returns the response.

  2. TCP Request - Sends a TCP request and waits for a response.

Advanced Nodes

  1. Link In - Receives messages from a Link Out node (flow linking).

  2. Link Out - Sends messages to a Link In node.

  3. Link Call - Dynamically calls a linked flow and returns a response.

  4. Catch - Catches errors thrown in a flow on the same tab.

  5. Status - Captures status updates from other nodes on the same tab.

  6. Comment - Adds notes or documentation to the flow (no processing).

Platform-Specific Nodes (if applicable)

  • RPi GPIO - Interfaces with Raspberry Pi GPIO pins (available only when running on a Raspberry Pi).

This list reflects the standard core nodes as of the latest Node-RED versions (e.g., 3.x series). The exact set may vary slightly depending on the installation environment (e.g., Raspberry Pi nodes are omitted in non-Pi environments).

Contrib Nodes in Node-RED

Contrib nodes are community-developed nodes available via npm and the Node-RED Library (flows.nodered.org). As of February 21, 2025, there are thousands of contrib nodes, with new ones added regularly. Listing all of them is impractical due to their sheer number and dynamic nature, but I can categorize and highlight some popular and widely-used examples based on common use cases and my knowledge of the ecosystem.

Categories and Examples of Contrib Nodes

  1. IoT and Hardware

  • node-red-contrib-dht-sensor - Interfaces with DHT11/DHT22 temperature/humidity sensors.

  • node-red-node-arduino - Communicates with Arduino boards via Firmata.

  • node-red-contrib-homematic - Controls Homematic smart home devices.

  • node-red-contrib-alexa-local - Integrates with Amazon Alexa locally.

  1. Messaging and Communication

  • node-red-contrib-telegrambot - Builds Telegram bots.

  • node-red-node-twitter - Sends/receives tweets (note: API changes may affect functionality).

  • node-red-contrib-slack - Integrates with Slack for messaging.

  • node-red-node-email - Sends and receives emails.

  • node-red-contrib-mongodb - Interacts with MongoDB.

  • node-red-contrib-influxdb - Writes/reads data to/from InfluxDB.

  • node-red-node-sqlite - Works with SQLite databases.

  1. UI and Dashboard

  • node-red-dashboard - Creates a web-based dashboard with widgets (e.g., buttons, gauges, charts).

  • node-red-contrib-ui - Additional UI elements for dashboards.

  • node-red-contrib-uibuilder - Customizable web UI with front-end framework support (e.g., Vue.js).

  1. Automation and Control

  • node-red-contrib-home-assistant-websocket - Integrates with Home Assistant for smart home automation.

  • node-red-contrib-schedex - Advanced scheduling with cron-like functionality.

  • node-red-contrib-loop - Adds looping capabilities to flows.

  1. Data Processing and Analysis

  • node-red-contrib-machine-learning - Provides machine learning capabilities (e.g., classification, outlier detection).

  • node-red-contrib-moment - Formats dates/times using Moment.js.

  • node-red-node-smooth - Applies smoothing functions (e.g., average, min, max) to data.

  1. Media and Streaming

  • node-red-contrib-dynamorse-core - Streams professional-quality media with NMOS support.

  • node-red-contrib-mjpeg - Handles MJPEG streams.

  1. Miscellaneous Utilities

  • node-red-contrib-counter - Creates a message counter.

  • node-red-contrib-config - Sets flow/global context values at startup.

  • node-red-contrib-os - Retrieves system information (e.g., CPU, network interfaces).

How to Find All Contrib Nodes

  • Node-RED Library: Visit flows.nodered.org to browse or search the full catalog of contrib nodes. You can filter by category, popularity, or keyword.

  • npm Search: Use npm search node-red-contrib in a terminal to list packages with "node-red-contrib" in their name (though some use scoped names like @scope/node-red-...).

  • Palette Manager: In the Node-RED editor, go to "Manage Palette" > "Install" tab to search and install nodes directly.

Since contrib nodes evolve rapidly, their exact list depends on what’s published to npm and the Node-RED Library as of today, February 21, 2025, 08:03 PM IST. For the most current list, I recommend checking the Node-RED Library online.

Summary

  • Core Nodes: Approximately 40+ nodes (listed above) covering input, output, processing, networking, and storage, included by default in Node-RED.

  • Contrib Nodes: Thousands of nodes, with examples spanning IoT, messaging, UI, automation, and more. The exact number and details are dynamic and best explored via the Node-RED Library or npm.

If you need a deeper dive into a specific category or node, let me know, and I can expand accordingly!
