@plainbroke you would have to use one of the prior releases

I am away from home now, look thru the tags on GitHub
I think last release will work

Looks like 2.30.0,
Have to install node 20.18.1

All has to be done manually

@mvrlogins yes, someone will have to update the module or downgrade the dependency in package.json

@mvrlogins do

npm install

Instead of

npm ci

Will ONLY do exactly watch matches package-lock.json which is rarely correct

@mvrlogins set

ipWhitelist=[],

'127.0.0.1',
'::ffff:127.0.0.1',
'::1',
'10.0.1.1/24'

the 1st 3 mean ONLY the same machine as MM is running on
and then also ONLY from address 10.0.1.1

@_V_ I see the same, except, if you click on the event, the popover comes up and the color is there…

the symbol doesn’t work…

there is text in the readme about the iconify icon set…

@_V_ the filter/transformer is INSIDE the Ext3 config:{} block…

{
module: "MMM_CalendarExt3",
position:
config:{
   .
.
.
.
  eventTransformer: (ev) => {
        if (ev.title.search("John") > -1){
              ev.symbol= "\f015";
             ev.color= "blue";
        }
        return ev
   },
 }
},

@_V_ sorry, don’t know about that icon library…

can you try one of the FA values…

"\f015"

for example

@_V_ ok, symbol is a list…

use
ev.symbol.push( “mdi:birthday-cake-outline”)

instead of
ev.symbol=

@_V_ if you want to set multiple properties on this event when the if condition is true

the you need { }
after the if()

otherwise only the first is used when the condition is true…

you would have to open the browser developers window to see what the problem is
ctrl-shift-i (chrome)
console tab,
put ext3 in the filter field.

@_V_

Yes, really that simple

eventTransformer: (ev) => {
  if (ev.title.search("John") > -1) {
          ev.symbol= "WHAT TO PUT HERE";
          ev.color= ‘blue’
  }
  return ev;
};

When using the font-awesome set,
They give you a name or a number, you can use either value
I dont know the set you picked

Fa house is ‘house’ or ‘\f015’
