My pi with node-red and the rest won't boot anymore after a powerfail.  
I have a backup of my config but that comes with a lot of errors. Missing nodes.  
Some are quite easy to find out what node it was (mysql) but others I cannot find.  
(ui\_tab, ui\_base, ui\_group, ui\_link f.i.)  
And the deveopment machine (pi) also hangs at boot.  
I can read the old sd card with another pi.  
But where can I find which nodes were installed?  
Or can I just copy the .node-red and the .npm maps to my new sd card?  
This is the list:  
ui\_tab  
ui\_group  
ui\_base  
ui\_link  
MySQLdatabase  
ui\_spacer  
zigbee2mqtt-server  
ui\_dropdown  
aggregator  
mysql  
ui\_chart  
ui\_date\_picker  
ui\_form  
ui\_gauge  
ui\_slider  
ui\_text  
ui\_button  
ui\_switch  
weekday  
eztimer  
ui\_text\_input  
ui\_numeric  
ui\_table  
cronplus  
ui\_led  
e-mail  
zigbee2mqtt-bridge  
zigbee2mqtt-in  
zigbee2mqtt-out  
zigbee2mqtt-get  
Is there a map where I can find which nodes are installed?

Assuming you used the official installer script, then look in `~/.node-red/package.json`

And if you restore package.json, then go into the .node-red folder and run  
`npm install`  
it will install any missing nodes. If you don't want the latest versions of them all then also restore package-lock.json before running npm install and it will install the same versions you had previously.

This flow will tell you everything. Just change the file paths in the read file nodes.
