Node-RED Nodes

A collection of nodes for Node-RED. See below for a list.


All of these nodes are available as individual npm packages. See the list below for the npm package names, or search npm.

This repository acts as an overall store for these nodes - and is not intended as a way to install them - unless you really do want some development.

To install - either use the manage palette option in the editor, or change to your Node-RED user directory.

    cd ~/.node-red
    npm install node-red-node-{filename}

To manually install using this repo:

  1. cd into the nodes directory of Node-RED
  2. Either:
    • download the zip of the repository and extract it
    • run git clone https://github.com/node-red/node-red-nodes.git
  3. run npm install in any of the node subfolders to install individual node's dependencies

Running Tests

Node.js v6 or newer is required. To run tests on all of the nodes you will need the node-red runtime:

npm i node-red-nodes
npm test


Now that we support npm installation of nodes we recommend people post their own nodes via npm. Please read the packaging guide notes.

For simple typos and single line fixes please just raise an issue pointing out our mistakes. If you need to raise a pull request please read our contribution guidelines before doing so.
