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 three types of Live Activities:

• metrics: best for live operational stats like server CPU and memory, queue depth, or replica lag
• segmented_progress: best for step-based workflows like deployments, backups, and ETL pipelines
• progress: best for continuous jobs like uploads, reindexes, and long-running migrations tracked as a percentage

When working with Live Activities via our API, you have two approaches tailored to different needs. First, the stateless mode is the simplest path - one API call can initiate or update an activity, and another ends it - no state tracking on your side.

This is ideal if you want minimal complexity, perfect for automated workflows like cron jobs.

In contrast, if you need precise lifecycle control, the classic approach offers distinct calls for start, updates, and end, giving you full control over the activity's state.

In the following sections, we'll break down how to implement each method so you can choose what fits your use case best.

Simple: Let ActivitySmith manage the Live Activity for you

Use a stable streamKey to identify the system or workflow you are tracking, such as a server, deployment, or build pipeline. This is especially useful for cron jobs and other scheduled tasks where you do not want to store activity_id between runs.

Metrics

const status = 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,
  },
});

Call stream(...) again with the same streamKey whenever the state changes.

End a stream

Use this when the tracked process is finished and you no longer want the Live Activity on devices. content_state is optional here; include it if you want to end the stream with a final state.

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: "%" },
    ],
  },
});

If you later send another stream(...) request with the same streamKey, ActivitySmith starts a new Live Activity for that stream again.

Stream responses include an operation field:

• started: ActivitySmith started a new Live Activity for this streamKey
• updated: ActivitySmith updated the current Live Activity
• rotated: ActivitySmith ended the previous Live Activity and started a new one
• noop: the incoming state matched the current state, so no update was sent
• paused: the stream is paused, so no Live Activity was started or updated
• ended: returned by endStream(...) after the stream is ended

Advanced: Full lifecycle control

Use these methods when you want to manage the Live Activity lifecycle yourself:

1. Call activitysmith.liveActivities.start(...).
2. Save the returned activity_id.
3. Call activitysmith.liveActivities.update(...) as progress changes.
4. Call activitysmith.liveActivities.end(...) when the work is finished.

Metrics Type

Use metrics when you want to keep a small set of live stats visible, such as server health, queue pressure, or database load.

Start

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

const activityId = start.activity_id;

Update

await activitysmith.liveActivities.update({
  activity_id: activityId,
  content_state: {
    title: "Server Health",
    subtitle: "prod-web-1",
    type: "metrics",
    metrics: [
      { label: "CPU", value: 76, unit: "%" },
      { label: "MEM", value: 52, unit: "%" },
    ],
  },
});

End

await activitysmith.liveActivities.end({
  activity_id: activityId,
  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,
  },
});

Segmented Progress Type

Use segmented_progress for jobs and workflows that move through clear steps or phases. It fits jobs like backups, deployments, ETL pipelines, and checklists. number_of_steps is dynamic, so you can increase or decrease it later if the workflow changes.

Start

const start = await activitysmith.liveActivities.start({
  content_state: {
    title: "Nightly database backup",
    subtitle: "create snapshot",
    number_of_steps: 3,
    current_step: 1,
    type: "segmented_progress",
    color: "yellow",
  },
});

const activityId = start.activity_id;

Update

await activitysmith.liveActivities.update({
  activity_id: activityId,
  content_state: {
    title: "Nightly database backup",
    subtitle: "upload archive",
    number_of_steps: 3,
    current_step: 2,
  },
});

End

await activitysmith.liveActivities.end({
  activity_id: activityId,
  content_state: {
    title: "Nightly database backup",
    subtitle: "verify restore",
    number_of_steps: 3,
    current_step: 3,
    auto_dismiss_minutes: 2,
  },
});

Progress Type

Use progress when the state is naturally continuous. It fits charging, downloads, sync jobs, uploads, timers, and any flow where a percentage or numeric range is the clearest signal.

Start

const start = await activitysmith.liveActivities.start({
  content_state: {
    title: "EV Charging",
    subtitle: "Added 30 mi range",
    type: "progress",
    percentage: 15,
    color: "lime",
  },
});

const activityId = start.activity_id;

Update

await activitysmith.liveActivities.update({
  activity_id: activityId,
  content_state: {
    title: "EV Charging",
    subtitle: "Added 120 mi range",
    percentage: 60,
  },
});

End

await activitysmith.liveActivities.end({
  activity_id: activityId,
  content_state: {
    title: "EV Charging",
    subtitle: "Added 200 mi range",
    percentage: 100,
    auto_dismiss_minutes: 2,
  },
});

Live Activity Action

Just like Actionable Push Notifications, Live Activities can have a button that opens provided URL in a browser or triggers a webhook. Webhooks are executed by the ActivitySmith backend.

Open URL action

const start = await activitysmith.liveActivities.start({
  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",
  },
});

const activityId = start.activity_id;

Webhook action

await activitysmith.liveActivities.update({
  activity_id: activityId,
  content_state: {
    title: "Reindexing product search",
    subtitle: "Shard 7 of 12",
    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);
}
