Migration guide: @awesome-cordova-plugins to @revenuecat/capacitor-purchases [docs]

Hi, how do I solve an error message that says "Missing identifier parameter in {}"?

Here is how I'm initializing purchases in a hook:

export function usePurchases() {
  const [isPurchasesInitialized, setIsInitialized] = useState(false)

  useEffect(() => {
    (async () => {
      const { Purchases, LOG_LEVEL } = (await import('@revenuecat/purchases-capacitor'))

      if (!isPurchasesInitialized) {
        const userUuid = await getUserUuid()
        Purchases.setLogLevel({ level: LOG_LEVEL.DEBUG });
        const apiKey = Capacitor.getPlatform() === 'android' ?
          process.env.REVENUECAT_API_KEY_ANDROID :
          process.env.REVENUECAT_API_KEY_IOS

        Purchases.configure({
          apiKey,
          appUserID: userUuid
        });
        myPurchases = Purchases

        setIsInitialized(true)
      }
    })()
  }, [isPurchasesInitialized]);

  return { isPurchasesInitialized, Purchases: myPurchases };
}

This is how I get and set the purchases' offerings and customer Info:

          const offerings = await Purchases.getOfferings();
          setOfferings(offerings)
          const customerInfo = process.env.APP_ENVIRONMENT === 'development' && SUBSCRIBE_DEV_USERS ?
            DEV_CUSTOMER_INFO :
            await Purchases.getCustomerInfo()

Here is the code that runs when the "Purchase Package" button is clicked:

console.log(offeringPackage)
await Purchases.purchasePackage(offeringPackage);

Here is what the offeringPackage log in the above code prints:

What am I doing wrong?

Thanks for the plugin!

Looks like the package you're purchasing needs to be passed at a property inside an options object like so:

await Purchases.purchasePackage({ aPackage: offeringPackage });

[mepc36]

As one more note:

this code/thread will be particularly helpful for anyone migrating from @awesome-cordova-plugins/purchases to this package. This new package is mainly a drop-in replacement, with the following changes:

1. Don't call Purchases.configureWith, but instead call Purchases.configure
2. This aforementioned .purchasePackage problem detailed above.
3. .restorePurchases() does work the same
4. Don't call Purchases.setDebugLogs, but Purchases.setLogLevel({ level: LOG_LEVEL.DEBUG }) instead.
5. customerInfo is now nested inside a larger returned object, so instead of this...

          const customerInfo = await Purchases.getCustomerInfo()

...call this:

          const { customerInfo } = await Purchases.getCustomerInfo()

If I run into any other problems, I will report back. Thanks!

Leaving open for visibility, maintainers, feel free to close if you don't think a meaningful subset of your users will want this!

@mepc36 Hi! I had a question about the migration.

I am using this code on a NextJS project:
import { Purchases } from "@revenuecat/purchases-capacitor"

await Purchases.configure({
apiKey,
appUserID: uid
})

But getting this error:
Error: "CapacitorPurchases" plugin is not implemented on android

Do you maybe have any idea why it is not using Purchases instead of CapacitorPurchases?

When using:
import { CapacitorPurchases } from '@capgo/capacitor-purchases';

CapacitorPurchases.setDebugLogsEnabled({ enabled: true }).then()

The app crashes instrantly, what would be a correct and functioning code solution at this moment?

@mepc36 thanks for sharing! Sorry for the delayed response, not sure how we missed this. @codykerns @tonidero we should have a section of the docs dedicated to this specific migration, I think @mepc36 is right and it'll be a common use case.

@Martijn0405 I'd recommend performing a clean install:

• remove the SDK
• reinstall the SDK through npm install @revenuecat/purchases-capacitor
• run ionic cap sync and then ionic cap run android

[tonidero]

Oh sorry we missed this! We have this doc with the changes in the API: https://github.com/RevenueCat/purchases-capacitor/blob/main/migrations/v6-MIGRATION.md, but we can add a link to that in the docs. Also, I think we might be able to explain a bit more about the changes in the doc

[tonidero]

One question @mepc36, about this point:

customerInfo is now nested inside a larger returned object, so instead of this...

     const customerInfo = await Purchases.getCustomerInfo()

...call this:

     const { customerInfo } = await Purchases.getCustomerInfo()

If I run into any other problems, I will report back. Thanks!

This seems like it didn't change from version 5.x of the plugin. Did you update from an older version of the plugin?

Edit: Sorry, please ignore the above, you did mention you're coming from @awesome-cordova-plugins. As Andy said, we are planning to create a guide to migrate from that to this plugin. Sorry for the noise!
