# Install node red in Raspberry Pi

All this step will show you how to install node-red on Raspberry Pi. Open the terminal of Raspberry Pi and do as below:

* **Install node:**
  * `$ sudo apt update`                 (*you need to update first*)
  * `$ sudo apt install nodejs`   (Install nodejs)
  * `$ node -v`                              (check version of nodejs if you get v10.12.0 you need to update to v14.5.0)
* **Update node if your node is v10.12.0:**
  * `$ curl -sL` [`https://deb.nodesource.com/setup_14.x`](https://deb.nodesource.com/setup_14.x) `| sudo -E bash -`                  (This command use for update your package repository)
  * `$ sudo apt install nodejs`   (install nodejs)
  * `$ node -v`                               (you will get node v14.5.0)
* **Install node-red:**
  * `$bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)`
    * This script will:
      * remove the pre-packaged version of Node-RED and Node.js if they are present
      * Install the current Node.js LTS release using the [NodeSource](https://github.com/nodesource/distributions/blob/master/README.md). If it detects Node.js is already installed from NodeSource, it will ensure it is at least Node 8, but otherwise leave it alone
      * install the latest version of Node-RED using npm
      * optionally install a collection of useful Pi-specific nodes
      * setup Node-RED to run as a service and provide a set of commands to work with the service
  * `$ sudo npm install -g npm@2.x`
  * `$ npm install node-red-dashboard` (If you did with all the step you will get node-red on your Raspberry Pi)
  * `$ node-red-start`       (to open your node red)
