Build apps with Push Notifications

lib/notifications.ts registers the Expo push token, creates Android channels from config, and upserts the token to a Supabase push_tokens table. Goodspeed generates Push Notifications as a standard part of every app, so the output is a working codebase from day one, not a scaffold you have to finish yourself.

WHAT GETS GENERATED

Built into every Push Notifications build

Every app Goodspeed generates with Push Notifications includes these production-ready patterns, wired together from the first build.

Item	Description	Strength
requestPermissionAndRegister helper	Requests notification permissions, reads the Expo push token from a physical device, creates Android channels from gasConfig, and upserts to the push_tokens table in Supabase.	Setup
Android notification channels from config	gasConfig.features.pushNotifications.channels is an array of channel configs. lib/notifications.ts creates them at app start using setNotificationChannelAsync.	Android
Global notification handler	A module-level setNotificationHandler sets shouldShowAlert, shouldPlaySound, and shouldSetBadge for all received notifications.	Handler
Supabase push_tokens table	A generated migration creates a push_tokens table with user_id, token, and platform columns. The token is upserted on every app start so stale tokens rotate automatically.	Backend
supabase/functions/send-push/ Edge Function	An Edge Function accepts a user ID and message payload, fetches the push token from push_tokens, and calls the Expo Push API to deliver the notification.	Delivery

REAL GENERATED CODE

A snippet from a Push Notifications app the studio shipped

This pattern comes straight out of the production groundwork every Goodspeed app is generated on. The studio generates Push Notifications code like this for every app in the pipeline, not a hello-world sample you have to grow into a real app.

Token registration

// lib/notifications.ts: register push token
export async function requestPermissionAndRegister(
  userId: string
): Promise<string | null> {
  if (isWeb || !ExpoNotifications || !Device?.isDevice) return null;
  const { status } = await ExpoNotifications.requestPermissionsAsync();
  if (status !== 'granted') return null;
  const token = (await ExpoNotifications.getExpoPushTokenAsync()).data;
  await supabase.from('push_tokens')
    .upsert({ user_id: userId, token, platform: Platform.OS },
             { onConflict: 'user_id' });
  return token;
}
