# Despia for Replit

> Ship your Replit web app to the App Store and Google Play with native billing, push notifications, attribution, and offline support built in.

You built your app in Replit. Despia gets it into the App Store and Google Play, with native billing, push notifications, install attribution, and offline support all included, without a separate React Native project.

***

## In-app purchases, built in

Replit's React Native mobile output requires installing and configuring a third-party purchase plugin (`react-native-purchases` or similar) and maintaining that native dependency. It is also a separate codebase from your Replit web app.

Despia wraps your existing Replit web app and includes RevenueCat as a built-in. No plugin, no React Native, no separate codebase.

```javascript theme={null}
import despia from 'despia-native'

const isDespia = navigator.userAgent.toLowerCase().includes('despia')

if (isDespia) {
    // Launch native paywall configured in your RevenueCat dashboard
    despia(`revenuecat://launchPaywall?external_id=${userId}&offering=default`)
} else {
    // Web fallback, link the purchase to their account
    window.location.href = `https://pay.rev.cat/<your_token>/${encodeURIComponent(userId)}`
}
```

Check entitlements on every app load, instant and offline-capable:

```javascript theme={null}
const data    = await despia('getpurchasehistory://', ['restoredData'])
const active  = (data.restoredData ?? []).filter(p => p.isActive)
const premium = active.some(p => p.entitlementId === 'premium')

window.onRevenueCatPurchase = () => checkEntitlements()
```

The web fallback links the purchase to the user's account via their ID. When they open the mobile app, the entitlement is already there.

***

## Push notifications, built in

OneSignal is included. No Expo push configuration, no separate plugin:

```javascript theme={null}
despia(`setonesignalplayerid://?user_id=${userId}`)
```

***

## Install attribution and ad analytics, built in

AppsFlyer ships with every Despia app. Three variables are injected automatically:

```javascript theme={null}
despia.appsFlyerReferrer     // 'tiktok_ad', 'meta_organic', 'organic'
despia.appsFlyerAttribution  // full attribution object
despia.appsFlyerUID          // unique AppsFlyer user ID

despia('appsflyer://log_event?event_name=purchase&event_values={"revenue":9.99}')
```

Replit's React Native path requires `react-native-appsflyer`, a separate plugin with its own native dependency and maintenance overhead.

***

## One codebase, not two

Replit's React Native output is a parallel implementation of your app, different navigation, different components, different platform-specific code paths. Any change to your web app needs to be replicated.

Despia wraps your Replit web app directly. One codebase. iOS and Android run the same code.

***

## CI/CD and deployment

Replit uses Expo's managed pipeline which prompts for your iCloud credentials for App Store submission. Despia uses Apple's official App Store Connect API with `.p8` key-based authentication throughout.

OTA updates are included at no cost with no MAU limits. Expo's equivalent, EAS Updates, is a paid service with MAU-based pricing.

***

## Using Replit and Despia together

Keep building your web app in Replit. Point Despia at your Replit app URL, add native features by installing `despia-native` and using the AI prompts on each feature page, and publish from the Despia dashboard.
