How to Get Missing Plugins in Node-RED

Node-RED is an open-source flow-based programming tool that provides an easy-to-use graphical interface for developing applications. Sometimes, you may encounter a missing plugin when deploying your flow, which can prevent you from deploying the flow properly. In this guide, we will provide step-by-step instructions on how to get missing plugins in Node-RED.


  1. Open Node-RED in your web browser.
  2. Click on the "Menu" button in the upper right-hand corner of the screen.
  3. Select "Manage palette" from the drop-down menu.
  4. In the "Manage palette" menu, select the "Install" tab.
  5. Use the search bar to find the missing plugin/node that you need to install.
  6. Select the correct plugin/node from the list of search results.
  7. Click on the "Install" button next to the plugin/node to install it.
  8. Wait for the installation to complete.
  9. Once the installation is complete, close the "Manage palette" menu by clicking on the "Close" button.
