Hello, my name is German. I’ve no idea how to build or create an installation or program file. I’ve no idea programming something. I’m a just a user and nothing more. There is a chor-js thing out there. I’m searching now for month but I did not find something usable for me. I love the Camunda modeler and I think it can be modified to use it for choreography diagrams. (Sorry for my English.)
Is there somebody to help me? I’m working on OS X.
Best

HI @germans
What exactly are you looking for help with - are you interested in running chor-js locally on your machine?
-Niall
Yes, locally on my MacBook.
Is there a reason why you can’t just the current live link
https://bpt-lab.org/chor-js-demo/ ?
If you ran it locally it would look exactly the same.
For documentation purposes, it would be very nice if that library could be used inside modeler 
A saved locally version of the website does not work if there is no network. When I’m out for interview this often happens. Safari hangs sometimes with this website.
An other solution is the Software cubetto. So there are ways - I would prefer the camunda modeler.
I’ll try and give you step-by-step instructions, but i don’t use a Mac so some of this might be different
Alright, well first you need to go and install Node.js: https://nodejs.org/dist/v12.18.4/node-v12.18.4.pkg
Once that’s installed you’ll need to download the project, you can do that by following the github link and using the download function:
Next you need to unzip the project and then open a terminal window which is open at the directory where you have the downloaded project. Then in the terminal enter the commant
npm install
and wait for it to finish installing. When it’s done enter
npm run dev
and wait until it’s started up then go to http://localhost:9013/ and you should see the local version running.
Yeah - again. 
It is so much easier to start an app. I hate this and I understand nothing what is happening here. I got a lot warnings an errors in the terminal window.

What exactly did you do before this occurred? what did you enter?
Hmm - good question. I followed the description.
It looks like I’m not alone: https://github.com/zalmoxisus/crossbuilder/issues/30
Some weeks ago I tried this by my own. I have no idea what I did. At that time I was not in the download directory.
I know it doesn’t really help you germans ( 
) but I’m on a Mac and followed Niall’s instructions that he wrote above and it started and ran OK for me.
I do get errors at startup as well, but the app does run OK when connect to via the URL shown at the end of the log in a browser…
