Is this the best way to update Node-Red on a raspberry pi? `update-nodejs-and-nodered`? And is there a way to get it to install nodes that I commonly use a batch rather than clicking on them individually in the Pallet Manager? Thank you all

Yes - as [described in our docs for the Pi](https://nodered.org/docs/getting-started/raspberrypi#installing-node-red)

You can do that from the command-line.

```auto
cd ~/.node-red
npm install my-favourite-node-1 my-favourite-node-2 my-favourite-node-3

```

And then restart Node-RED.

Willing to update my Node-Red local installation (installed on my Rasp) from the current version 0.20.7 to the last one I just want to know it the official updating script will save all my installed palettes and all of my files (flows.json, flows\_cred.json, settings.json etc...). In a word after successfully run the update script all my previous flows will run as before or do I have to re-install palettes, set input credentials in the config nodes?

@lenny1972 the upgrade script will upgrade Node-RED and leave your user data (flows etc) alone

If you did have a problem you can always restore your flow files from your backup.

if you are on an x64 machine - or any raspberry pi [ARM6 or ARM7 or ARM64]. I've written this binary that will uninstall nodejs, and install the latest version. You can check out the source code here:

>
> Install NodeJs on your Raspberry Pi 1, 2, 3, 4, zero, and zero w - GitHub - audstanley/NodeJs-Raspberry-Pi: Install NodeJs on your Raspberry Pi 1, 2, 3, 4, zero, and zero w

This doesn't solve upgrading the version of Node-Red, but if Node-Red requires an update NodeJs than this will get you there. 🙂
