Hello I´m trying to use themes on node-red but it does not work.
My setup:
cd /mnt/dietpi_userdata/node-red
npm install @node-red-contrib-themes/theme-collection
Edit the settings.js
root@DietPi:/mnt/dietpi_userdata/node-red# vi settings.js
…
editorTheme: {
theme: “dark”
},
…
and restart node-red via #service node-red restart
But the theme don´t work.
Welcome to our community.
I guess installation would need to be done as user nodered
cd /mnt/dietpi_userdata/node-red
sudo -u nodered npm i @node-red-contrib-themes/theme-collection
Inside settings.js you added a new block? Or did you used the existing block?
editorTheme: {
/** The following property can be used to set a custom theme for the editor.
* See https://github.com/node-red-contrib-themes/theme-collection for
* a collection of themes to chose from.
*/
theme: "dark",
/** To disable the 'Welcome to Node-RED' tour that is displayed the first
* time you access the editor for each release of Node-RED, set this to false
*/
//tours: false,
palette: {
/** The following property can be used to order the categories in the editor
* palette. If a node's category is not in the list, the category will get
* added to the end of the palette.
* If not set, the following default order is used:
*/
//categories: ['subflows', 'common', 'function', 'network', 'sequence', 'parser', 'storage'],
},
projects: {
/** To enable the Projects feature, set this value to true */
enabled: false,
workflow: {
/** Set the default projects workflow mode.
* - manual - you must manually commit changes
* - auto - changes are automatically committed
* This can be overridden per-user from the 'Git config'
* section of 'User Settings' within the editor
*/
mode: "manual"
}
},
I´ve installed the theme-collection as “nodered” user as suggested.
Is the File mnt/dietpi_userdata/node-red/settings.js the correct file ?
I tried the Setup as new block (copied from this thread) and as edit of the existing block. Both attempts does not work.
Thanks for your help.
I´m new to dietpi and a look in the nodered web interface says it runs Version 1.3.7 Maintenance Release. Themes works from version 2.x, so is this the issue ? Why do dietpi install this old version ?
We don’t install a specific version. We just run sudo -u nodered npm i --no-audit node-red. On my test system I get 3.0.2: Maintenance Release
You could have filled the issue template at the beginning. At least this would have given some more information on your system
Sorry, here are some information from my system:
G_DIETPI_VERSION_CORE=8
G_DIETPI_VERSION_SUB=9
G_DIETPI_VERSION_RC=2
G_GITBRANCH=‘master’
G_GITOWNER=‘MichaIng’
When I use # sudo -u nodered npm i --no-audit node-red
I get the following Messages:

I tried to use the command as root and the Release shown in the WebInterface ist now: 3.0.2: Maintenance Release. Now the dark Theme is working ! 
thank you very much !
Ahmmmm this would need to have been done from /mnt/dietpi_userdata/node-red sub directory and not root user home. Of course you had permission issues there.
Oh, my fault 
i tried:
root@DietPi:/mnt/dietpi_userdata/node-red# sudo -u nodered npm i --no-audit node-red
up to date in 2s
40 packages are looking for funding
run npm fund for details
Have I do something to fix my fault or is it okay ?
let’s the root user home directory
ls -la /root
root@DietPi:~# ls -la
