Bucket Browser SDK

Basic client for Bucket.co. If you're using React, you'll be better off with the Bucket React SDK.

Install

The package can be imported or used directly in a HTML script tag:

A. Import module

import bucket from "@bucketco/browser-sdk";

const user = {
  id: 42,
  role: "manager",
};

const company = {
  id: 99,
  plan: "enterprise",
};

const bucketClient = new BucketClient({ publishableKey, user, company });

await bucketClient.initialize();

const { isEnabled, track } = bucketClient.getFeature("huddle");

if (isEnabled) {
  // show feature. When retrieving `isEnabled` the client automatically
  // sends a "check" event for the "huddle" feature which is shown in the
  // Bucket UI.

  // On usage, call `track` to let Bucket know that a user "used" the feature
  track();
}

// `track` just calls `bucketClient.track(<featureKey>)` to send an event using the same feature key
// You can also use `track` on the client directly to send any custom event.
bucketClient.track("huddle");

B. Script tag (client-side directly in html)

See example/browser.html for a working example:

<script src="https://cdn.jsdelivr.net/npm/@bucketco/browser-sdk@1"></script>
<script>
  const bucket = new BucketBrowserSDK.BucketClient({
    publishableKey: "publishableKey"
    user: { id: "42" },
    company: { id: "1" },
  });

  bucket.initialize().then(() => {
    console.log("Bucket initialized");
    document.getElementById("loading").style.display = "none";
    document.getElementById("start-huddle").style.display = "block";
  });
</script>
<span id="loading">Loading...</span>
<button
  id="start-huddle"
  style="display: none"
  onClick="bucket.track('Started huddle')"
>
  Click me
</button>

Init options

Supply these to the constructor call (3rd argument)

{
  logger: console, // by default only logs warn/error, by passing `console` you'll log everything
  host?: "https://front.bucket.co",
  sseHost?: "https://livemessaging.bucket.co"
  feedback?: undefined // See FEEDBACK.md
  featureOptions?: {
    fallbackFeatures?: string[]; // Enable these features if unable to contact bucket.co
    timeoutMs?: number; // Timeout for fetching features
    staleWhileRevalidate?: boolean; // Revalidate in the background when cached features turn stale to avoid latency in the UI
  };
}

Feature toggles

Bucket can determine which features are active for a given user/company. The user/company is given in the BucketClient constructor.

If you supply user or company objects, they require at least an id property. In addition to the id, you must also supply anything additional that you want to be able to evaluate feature targeting rules against.

Attributes cannot be nested (multiple levels) and must be either strings, integers or booleans.

Built-in attributes:

  • name (display name for user/company)
const bucketClient = new BucketClient({
  publishableKey,
  user: { id: "user_123", name: "John Doe", role: "manager" },
  company: { id: "company_123", "Acme, Inc", plan: "enterprise" },
});

Qualitative feedback

Bucket can collect qualitative feedback from your users in the form of a Customer Satisfaction Score and a comment.

Automated feedback collection

The Bucket Browser SDK comes with automated feedback collection mode enabled by default, which lets the Bucket service ask your users for feedback for relevant features just after they've used them.

Note: To get started with automatic feedback collection, make sure you've set user in the BucketClient constructor.

Automated feedback surveys work even if you're not using the SDK to send events to Bucket. It works because the Bucket Browser SDK maintains a live connection to Bucket's servers and can automatically show a feedback prompt whenever the Bucket servers determines that an event should trigger a prompt - regardless of how this event is sent to Bucket.

You can find all the options to make changes to the default behavior in the Bucket feedback documentation.

Bucket feedback UI

Bucket can assist you with collecting your user's feedback by offering a pre-built UI, allowing you to get started with minimal code and effort.

Bucket feedback SDK

Feedback can be submitted to Bucket using the SDK:

bucketClient.feedback({
  featureId: "my_feature_id", // String (required), copy from Feature feedback tab
  score: 5, // Number: 1-5 (optional)
  comment: "Absolutely stellar work!", // String (optional)
});

Bucket feedback API

If you are not using the Bucket Browser SDK, you can still submit feedback using the HTTP API.

See details in Feedback HTTP API

Zero PII

The Bucket Browser SDK doesn't collect any metadata and HTTP IP addresses are not being stored.

For tracking individual users, we recommend using something like database ID as userId, as it's unique and doesn't include any PII (personal identifiable information). If, however, you're using e.g. email address as userId, but prefer not to send any PII to Bucket, you can hash the sensitive data before sending it to Bucket:

import bucket from "@bucketco/browser-sdk";
import { sha256 } from 'crypto-hash';

bucket.user(await sha256("john_doe"));

Use of cookies

The Bucket Browser SDK uses a couple of cookies to support automated feedback surveys. These cookies are not used for tracking purposes and thus should not need to appear in cookie consent forms.

The two cookies are:

  • bucket-prompt-${userId}: store the last automated feedback prompt message ID received to avoid repeating surveys
  • bucket-token-${userId}: caching a token used to connect to Bucket's live messaging infrastructure that is used to deliver automated feedback surveys in real time.

Typescript

Types are bundled together with the library and exposed automatically when importing through a package manager.

Content Security Policy (CSP)

If you are running with strict Content Security Policies active on your website, you will need to enable these directives in order to use the SDK:

DirectiveValuesReason
connect-srchttps://front.bucket.coBasic functionality`
connect-srchttps://livemessaging.bucket.coServer sent events for use in automated feedback surveys, which allows for automatically collecting feedback when a user used a feature.
style-src'unsafe-inline'The feedback UI is styled with inline styles. Not having this directive results unstyled HTML elements.

If you are including the Bucket tracking SDK with a <script>-tag from jsdelivr.net you will also need:
