Hello,

I have a very simple patch where i load a node.script and it is giving me this error:

node.script: Node script not ready can't handle message bang

  • my js file is in the same folder as my patch file

  • all syntax is correct, checked multiple times

test js is: 

post("test.js loaded");
function bang() {
    outlet(0, 12345);
}
testy.maxpat
Max Patch

and i've uploaded my maxpat file.

please help and thanks in advance

Node is a little different to regular js/v8, you need to import the max-api and reference it for each function call:

const max = require('max-api');

max.post("hello");

max.addHandler("bang", () => {
    max.outlet(0, 12345);
});

I've also added a [loadbang] -> [script start] -> [node.script test.js]
This ensures the script starts as soon as the patcher has loaded. You usually need to start the script before calling functions within it.

Max Patch
Copy patch and select New From Clipboard in Max.

Patch above. File -> New From Clipboard. Be sure to re-attach the updated test.js. Hope this helps!

P.S: [node.script] has 1 outlet for messages, therefore you usually don't need to reference "0" as the first outlet argument. Instead, this acts as a list of args.
