Installation

npm install activitysmith

Setup

import ActivitySmith from "activitysmith";

const activitysmith = new ActivitySmith({
  apiKey: process.env.ACTIVITYSMITH_API_KEY,
});

CommonJS:

const ActivitySmith = require("activitysmith");

const activitysmith = new ActivitySmith({
  apiKey: process.env.ACTIVITYSMITH_API_KEY,
});

Push Notifications

Send a Push Notification

await activitysmith.notifications.send({
  title: "New subscription 💸",
  message: "Customer upgraded to Pro plan",
});

Rich Push Notifications with Media

await activitysmith.notifications.send({
  title: "Homepage ready",
  message: "Your agent finished the redesign.",
  media: "https://cdn.example.com/output/homepage-v2.png",
  redirection: "https://github.com/acme/web/pull/482",
});

Send images, videos, or audio with your push notifications, press and hold to preview media directly from the notification, then tap through to open the linked content.

What will work:

• direct image URL: .jpg, .png, .gif, etc.
• direct audio file URL: .mp3, .m4a, etc.
• direct video file URL: .mp4, .mov, etc.
• URL that responds with a proper media Content-Type, even if the path has no extension

Actionable Push Notifications

Actionable push notifications can open a URL on tap or trigger actions when someone long-presses the notification. Webhooks are executed by the ActivitySmith backend.

await activitysmith.notifications.send({
  title: "New subscription 💸",
  message: "Customer upgraded to Pro plan",
  redirection: "https://crm.example.com/customers/cus_9f3a1d", // Optional
  actions: [
    {
      title: "Open CRM Profile",
      type: "open_url",
      url: "https://crm.example.com/customers/cus_9f3a1d",
    },
    {
      title: "Start Onboarding Workflow",
      type: "webhook",
      url: "https://hooks.example.com/activitysmith/onboarding/start",
      method: "POST",
      body: {
        customer_id: "cus_9f3a1d",
        plan: "pro",
      },
    },
  ], // Optional (max 4)
});

Live Activities

There are four types of Live Activities:

• stats: best for showing business numbers side by side, such as revenue, sales, new users, conversion, refunds, or any other value you want visible at a glance
• metrics: best for live percentage values that change often, like server CPU, memory usage, disk usage, or error rate
• segmented_progress: best for anything that moves through clear stages, like deployments, onboarding flows, backups, ETL pipelines, migrations, and AI agent runs
• progress: best for tracking real-time progress with percentage, like tasks, backups, migrations, syncs, or uploads

Start & Update Live Activity

Use a stable streamKey to identify the metric, job, deployment, or system you want to keep visible. The first stream(...) call starts the Live Activity. Later calls with the same streamKey update it.

Stats

await activitysmith.liveActivities.stream("sales-hourly", {
  content_state: {
    title: "Sales",
    subtitle: "last hour",
    type: "stats",
    metrics: [
      { label: "Revenue", value: "$2430", color: "blue" },
      { label: "Orders", value: "37", color: "green" },
      { label: "Conversion", value: "4.8%", color: "magenta" },
      { label: "Avg Order", value: "$65.68", color: "yellow" },
      { label: "Refunds", value: "$84", color: "red" },
      { label: "New Buyers", value: "18", color: "cyan" },
    ],
  },
});

Metrics

await activitysmith.liveActivities.stream("prod-web-1", {
  content_state: {
    title: "Server Health",
    subtitle: "prod-web-1",
    type: "metrics",
    metrics: [
      { label: "CPU", value: 9, unit: "%" },
      { label: "MEM", value: 45, unit: "%" },
    ],
  },
});

Segmented Progress

await activitysmith.liveActivities.stream("nightly-backup", {
  content_state: {
    title: "Nightly Backup",
    subtitle: "upload archive",
    type: "segmented_progress",
    number_of_steps: 3,
    current_step: 2,
  },
});

Progress

await activitysmith.liveActivities.stream("search-reindex", {
  content_state: {
    title: "Search Reindex",
    subtitle: "catalog-v2",
    type: "progress",
    percentage: 42,
  },
});

End Live Activity

Call endStream(...) with the same streamKey to dismiss the Live Activity. You can include final values before it is removed. By default, iOS removes the Live Activity after two minutes. Set auto_dismiss_minutes to choose a different dismissal time, including 0 for immediate dismissal.

await activitysmith.liveActivities.endStream("prod-web-1", {
  content_state: {
    title: "Server Health",
    subtitle: "prod-web-1",
    type: "metrics",
    metrics: [
      { label: "CPU", value: 7, unit: "%" },
      { label: "MEM", value: 38, unit: "%" },
    ],
    auto_dismiss_minutes: 2,
  },
});

Live Activity Action

Live Activities can include one optional action button. Use it to open a URL from the Live Activity or trigger a backend webhook.

Open URL action

await activitysmith.liveActivities.stream("prod-web-1", {
  content_state: {
    title: "Server Health",
    subtitle: "prod-web-1",
    type: "metrics",
    metrics: [
      { label: "CPU", value: 76, unit: "%" },
      { label: "MEM", value: 52, unit: "%" },
    ],
  },
  action: {
    title: "Open Dashboard",
    type: "open_url",
    url: "https://ops.example.com/servers/prod-web-1",
  },
});

Webhook action

await activitysmith.liveActivities.stream("search-reindex", {
  content_state: {
    title: "Reindexing product search",
    subtitle: "Shard 7 of 12",
    type: "segmented_progress",
    number_of_steps: 12,
    current_step: 7,
  },
  action: {
    title: "Pause Reindex",
    type: "webhook",
    url: "https://ops.example.com/hooks/search/reindex/pause",
    method: "POST",
    body: {
      job_id: "reindex-2026-03-19",
      requested_by: "activitysmith-node",
    },
  },
});

Channels

Channels are used to target specific team members or devices. Can be used for both push notifications and live activities.

await activitysmith.notifications.send({
  title: "New subscription 💸",
  message: "Customer upgraded to Pro plan",
  channels: ["sales", "customer-success"], // Optional
});

Widgets

ActivitySmith lets you display any value on your Lock Screen with widgets - SaaS metrics, revenue, signups, uptime, habits, or anything else you want to track. Create a metric in the web app, then update the metric value using our API, add a widget to your lock screen and it will fetch the latest update automatically.

Use the metric key to update its value.

await activitysmith.metrics.update("deploy.success_rate", 99.9);

String metric values work too.

await activitysmith.metrics.update("prod.status", "healthy");

Error Handling

try {
  await activitysmith.notifications.send({
    title: "New subscription 💸",
  });
} catch (error) {
  console.error(error);
}
