Customizing Passes with passkit-generator

[mis101247]

Hello,

I'm working on customizing a pass using passkit-generator and I've run into some issues. I'd really appreciate your help with the following:

Problem with Folder Model:
I have an existing mypass.pass file. When I load it using the Folder Model, I can't change any styles or colors. Is this normal? Or is there a way to modify styles when using the Folder Model?

I found #191, so I change to create pass by Buffer Model.

Issue with Buffer Model:
To get around the above limitation, I tried using the Buffer Model to create my pass. However, now I can't add personalization.json and personalizationLogo.png files.

const pass = new PKPass(
        {
          'personalization.json': Buffer.from(
            personalizationJsonString,
            'utf-8',
          ),
          'personalizationLogo.png': fs.readFileSync(personalizationLogo),
          'pass.json': Buffer.from(passJsonString),
          'strip.png': fs.readFileSync(resizedStrip),
          'strip@2x.png': fs.readFileSync(resizedStrip2x),
          'logo.png': fs.readFileSync(resizedLogo),
          'logo@2x.png': fs.readFileSync(resizedLogo2x),
          'icon.png': fs.readFileSync(resizedLogo2x),
          'icon@2x.png': fs.readFileSync(resizedIcon),
        },
        {
          wwdr,
          signerCert,
          signerKey,
          signerKeyPassphrase,
        },
        {
          // keys to be added or overridden
          serialNumber: 'xxxxxxx',
        },
      );

My specific questions are:

How can I correctly add personalization.json and personalizationLogo.png when using the Buffer Model?
Is there a best practice that allows both style flexibility and personalization?
Am I doing something wrong? If so, how can I fix it?

Thank you very much for your time and help!

Hey @mis101247, thanks for using passkit-generator!

Today I cannot help you as I'm away. I'll likely be able to help you maybe this night or tomorrow, not sure yet.

In the meanwhile, I suggest you reading the documentation. There are some details and methods I think you'll need, like the usage of addBuffer(), which is called underneath when you create a pass instance.

Also, I suggest you looking at the logs, as passkit-generator may print some things if there is a validation error.

Last but not least, I'd like to ask you to edit your first message and add how you were trying to change the colors or other info, when using folder model.

Let me know if you are able to solve. I'll examine your question more deeply ASAP, thanks for understanding.

What does it mean "cannot add"? You have any log, a crash or did you open the pkpass file as zip and verified the file wasn't added?

[alexandercerutti]

Btw, this will never work: addBuffer is a method, not a property.

pass.addBuffer['personalizationLogo.png'] = ...

I add the personalization.json and .png buffer through new PKPass(), but when I convert the generated pkpass file to a zip file and open it, I don't see the personalization.json or related image files.

[mis101247]

And I will try to using pass.addBuffer('personalizationLogo.png'), let you know the result.

Thank you for your package :)

If personalization files are invalid or nfc property is not set, they get trimmed away and you should see a log in the console. If you don't see anything, there could be a bug.

Let me know.
