@absolutejs/dispatch-fcm

Firebase Cloud Messaging HTTP v1 PushAdapter for @absolutejs/dispatch. It uses google-auth-library Application Default Credentials by default, so access tokens remain short-lived and service-account keys do not enter message payloads or dispatch core.

import { createDispatcher } from "@absolutejs/dispatch";
import { createFcmAdapter } from "@absolutejs/dispatch-fcm";

const dispatcher = createDispatcher({
  push: createFcmAdapter({ projectId: process.env.FCM_PROJECT_ID! }),
});

Use /topics/name or metadata.targetType: 'topic' for a topic. FCM data values are normalized to strings as required by HTTP v1. Advanced android, apns, and webpush objects can be supplied in message metadata.
