How to save my work in node-red?

[Alpenskipper]

Hi!

I started to experiment with node-red and - it's great!
After fiddeling around with freeboard for more than a year, it just took my a few hours to create a working dashboard, where I can monitor my boat when at home.

How can I preserve (and restore ) my work in case of system crashes or updates?

best regards

Martin

Couple of ideas - Copy this file somewhere safe, it's all your hard work  
/home/pi/.node-red/flows_openplotter.json

Also, I use evernote for anything and everything, you can highlight just one flow then use the export menu in node-red to save it  into evernote so you can find it later. Same with handy bits of function code. 

Also . here's a backup flow I use most days, you should be able to edit to suit your own machine - 

Code:

Node-red must be one of the most useful pieces of free software there is

i highlight my flows and export to clipboard and then paste and save them to text editor on a usb drive or google drive.
