Return multiple passes

[brannan-holland]

Thank you @alexandercerutti for putting this well documented package together!

I have been attempting to implement an "Add all" option for passes that are grouped together with little success.

Two key issues I have encountered:

• Only way I could figure to add pass together was to concat the buffer for each. This returned a zip file. Im sure there is a much better way to do this.
• I have not found a great way to modify the "groupingIdentifier" when using form method.

New to a lot of this and do not post often. Please let me know if there is anything else I can include!

Hey @brannan-holland! Thanks for using passkit-generator!

Returning multiple passes is a weird matter.
Apple officially supports .pkpasses, which is a bundle containing multiple .pkpass inside, but apparently only a few apps support them: Safari, Mail and I don't know who else, and if there is something that developers can do in their app to support them.

passkit-generator has the support to .pkpasses if you need them.

Otherwise you'll need to implement something custom I guess, which involves designing how you are receiving your .pkpass files in the app (because that means you cannot probably use another way)

For what concerns the groupingIdentifier, I'm not exactly sure what you are asking.

Let me know!

Ill look into .pkpasses and see if this is a good option!

I have the groupingIdentifier configured in my .pass model currently. I know I will need to dynamically set this value as im generating the passes. I see I can set certain fields such as barcode or text fields using PKPass.from. I cant seem to find the best way to set groupingIdentifier

@brannan-holland groupingIdentifier is not a property that requires a strict validation on passkit-generator side. For this reason, you can pass it in the props when you initialize PKPass.from.

Look here: https://github.com/alexandercerutti/passkit-generator/wiki/API-Documentation-Reference#-from-a-template

Look in the page for getAdditionalPropsForThisPassSomehow() example function to see how it gets used.

passkit-generator/examples/self-hosted/src/PKPasses.ts

Lines 57 to 77 in bab4117

	const pass = new PKPass(
	{},
	{
	wwdr: certificates.wwdr,
	signerCert: certificates.signerCert,
	signerKey: certificates.signerKey,
	signerKeyPassphrase: certificates.signerKeyPassphrase,
	},
	{
	...props,
	description: "Example Apple Wallet Pass",
	passTypeIdentifier: "pass.com.passkitgenerator",
	// Be sure to issue different serialNumbers or you might incur into the bug explained above
	serialNumber: `nmyuxofgna${Math.random()}`,
	organizationName: `Test Organization ${Math.random()}`,
	teamIdentifier: "F53WB8AE67",
	foregroundColor: `rgb(${getRandomColorPart()}, ${getRandomColorPart()}, ${getRandomColorPart()})`,
	labelColor: `rgb(${getRandomColorPart()}, ${getRandomColorPart()}, ${getRandomColorPart()})`,
	backgroundColor: `rgb(${getRandomColorPart()}, ${getRandomColorPart()}, ${getRandomColorPart()})`,
	},
	);

new PKPass is not different from PKPass.from in this sense.

The code you see above, is from an example in the repo that shows how to create .pkpasses. I suggest you to fully read it, from top to bottom comments included to understand more.

[brannan-holland]

Disregard. .pkpasses looks to solve both problems!

Thank you for your help!
