See - unfortunately, this repo is no longer maintained and is known to not work with the latest versions of node-red / Firebase. Perhaps you can take up the cause - if you are up to the challenge and want to submit a complete PR or a new repo that wants to take this npm package name, please submit a PR or File a Pull Request and I will be happy to review.

NPM version NPM downloads

node-red nodes for interacting with Firebase.

The goal of this project is to provide an elegant GUI that allows you to interact with your Firebase data using Node-Red.

As a side benefit, these nodes should be a natural complement to the data explorer interface offered by the Firebase Forge and a faster/easier to use tool than diving straight into the programming libraries offered for all of the Firebase supported platforms.


Run the following command after you have done a global install of Node-RED (as described at

sudo npm install -g node-red-contrib-firebase

Manual Installation

The following instructions assume a standard installation of Node-Red. Please adjust directories accordingly if a non-standard installation is used.
The Node-Red user directory is printed to the Terminal whenever Node-Red is launched.
Windows users will need to replace "$HOME" with "%HOMEPATH%" and replace forwardslashes with backslashes.

To manually install :

  1. Download this repository (via git clone, as a .zip, etc.)

  2. Launch your favorite Terminal / Command Prompt

  3. Create a nodes folder in the Node-Red user directory.
    Don't worry if you see a cannot create directory, File exists error - that simply means this directory has already been created.

        mkdir $HOME/.node-red/nodes
  4. cd into the .node-red/nodes user directory of Node-RED

    cd $HOME/.node-red/nodes
  5. Copy the node-red-contrib-firebase folder into the .node-red/nodes directory. The final directory structure should be $HOME/.node-red/nodes/node-red-contrib-firebase/

    cp -r $HOME/Downloads/node-red-contrib-firebase/ ./node-red-contrib-firebase/
  6. cd into the node-red-contrib-firebase folder

    cd node-red-contrib-firebase
  7. Install the required dependencies

    npm install


To use the nodes, launch Node-RED (see for help getting started).

The firebase nodes will appear in their own "firebase" catagory on the Node-Red pallet. Drag and drop any node onto the canvas and configure as you would any other node-red node. Node specific configuration information for each node is included in the info pane in Node-Red.


the project uses Semantic Versioning so hopefully no big surprises.

Unfortunately, Node-RED is a bit "stickier" than a traditional node.js app. If you find that things are acting strangely after updating to a new version, dragging a fresh node onto the workspace from the palette (potentially with fresh config nodes) should clear it up.

Example Application

If you are brand new to Node-Red, one simple way to get started is to use an existing flow.

  • Start by copying the following to your clipboard

  • Launch Node-Red and open the web user interface (Located at by default).

  • Click the menu drop down in the top right corner and select Import -> Clipboard.

  • Paste the contents of your clipboard in and click "OK".

  • Click in the palette to place the nodes.

  • You now need to configure login credentials for each node with a Red Triangle. You can add new credentials by double clicking on any firebase node and clicking on the pencil icon in the top right corner of the edit dialog box. Once you have created a set of credentials they will be available in the drop down box for use in other nodes.

  • Press the Deploy Button in the top right corner and begin experimenting!

Potential Node-Red Installation Issues on Windows

For Node-Red installations on Windows using Node.JS v0.12, you may run into missing compiler dependencies from npm and see MSBUILD errors. Installing Microsoft Visual Studio Community should fix this issue.

Node.JS on Windows behind a Corporate Proxy Server

If you are using Node.JS on Windows behind a corporate proxy server, you will likely run into issues with node programs and npm. Run the following commands to inform node of your proxy settings (modify the values to fit your proxy setup):

npm config set proxy
npm config set https-proxy

If authentication is required by your proxy, you may need to use the following syntax:

npm config set proxy
npm config set https-proxy

To undo these changes for use outside of a proxied environment run

npm config delete proxy
npm config delete https-proxy

Feedback and Support

For feedback or support on the Firebase Nodes, please submit issues to the Github issue tracker.

For more information, feedback, or community support on Node-Red, see the Node-Red Website, Google groups forum, and Github Repository.

//TODO: List

  • All of the ones scattered throughout the code

  • testFlows.json to provide good unit testing coverage

  • Code cleanup and commenting (using jsDoc?)

  • Make some errors "sticky" so we don't report inappropriate status in case the page is loaded after initial deploy as the errors could be missed later and make debugging flows difficult (need to come up with a list of what is/isn't recoverable and under what conditions...)

  • Add support for remaining Firebase Authentication strategies including facebook, twitter, GitHub and Google. (the Twitter Node likely should provide good inspiration for how to do this)

  • Expose more of the Firebase API and add nodes for creating users, updating passwords, etc.?
