Fullstory Browser SDK

Fullstory's browser SDK lets you manage Fullstory data capture on your site as well as retrieve deep links to session replays and send your own custom events. More information about the Fullstory API can be found at https://developer.fullstory.com.

NOTE: this is the documentation for version 2. For version 1 documentation, please see @fullstory/browser@1.7.1.

Install the SDK

with npm

npm i @fullstory/browser --save

with yarn

yarn add @fullstory/browser

Migrating to Version 2.x.x

In version 2.x.x, init is a separate named export from FullStory. You will need to update all of your wildcard ('*') imports to explicit named imports.

Version 1.x.x

import * as FullStory from '@fullstory/browser';

Version 2.x.x

import { FullStory, init } from '@fullstory/browser';

init

You can use the named import init by itself:

import { init } from '@fullstory/browser';

init({ orgId: 'my-org-id' })

You can also rename the function for readability:

import { init as initFullStory } from '@fullstory/browser';

initFullStory({ orgId: 'my-org-id' })

FullStory

The FullStory named export is equivalent to the global FS object described in the developer documentation. You can use it to make all version 2 API calls:

import { FullStory } from '@fullstory/browser';

FullStory('trackEvent', {
  name: 'My Event',
  properties: {
    product: 'Sprockets',
    quantity: 1,
  },
})

Initialize the SDK

Call the init() function with options as soon as you can in your website startup process. Calling init after successful initialization will trigger console warnings - if you need to programmatically check if FullStory has been initialized at some point in your code, you can call isInitialized().

Configuration Options

The only required option is orgId, all others are optional.

• orgId - Sets your Fullstory Org Id. Find out how to get your Org Id here.
• debug - When set to true, enables Fullstory debug messages; defaults to false.
• host - The recording server host domain. Can be set to direct recorded events to a proxy that you host. Defaults to fullstory.com.
• script - Fullstory script host domain. Fullstory hosts the fs.js recording script on a CDN, but you can choose to host a copy yourself. Defaults to edge.fullstory.com.
• namespace - Sets the global identifier for Fullstory when conflicts with FS arise; see help.
• cookieDomain - Overrides the cookie domain. By default, cookies will be valid for all subdomains of your site; if you want to limit the cookies to a specific subdomain, you can set the domain value explicitly. More information can be found here.
• recordCrossDomainIFrames - Defaults to false. Fullstory can record cross-domain iFrames if: 1. The Fullstory Browser SDK is running in the cross-domain iFrame and 2. recordCrossDomainIFrames is set to true in the cross-domain iFrame and 3. The Fullstory Browser SDK is running in the parent page of the cross-domain iFrame. Click here for a detailed explanation of what "cross-domain" means. Before using, you should understand the security implications, and configure your Content Security Policy (CSP) HTTP headers accordingly - specifically the frame-ancestors directive. Failure to configure your CSP headers while using this setting can bypass IFrames security protections that are included in modern browsers. More information about cross-domain iFrame recording can be found on our Knowledge Base. Note: the recordCrossDomainIFrames parameter is the same as the window['_fs_run_in_iframe'] referenced in the KB article.
• recordOnlyThisIFrame - When set to true, this tells Fullstory that the IFrame is the "root" of the recording and should be its own session; defaults to false. Use this when your app is embedded in an IFrame on a site not running Fullstory or when the site is running Fullstory, but you want your content sent to a different Fullstory org.
• devMode - Set to true if you want to deactivate Fullstory in your development environment. When set to true, Fullstory will shutdown recording and all subsequent SDK method calls will be no-ops. At the time init is called with devMode: true, a single event call will be sent to Fullstory to indicate that the SDK is in devMode; this is to help trouble-shoot the case that the SDK was accidentally set to devMode: true in a production environment. Additionally, any calls to SDK methods will console.warn that Fullstory is in devMode. Defaults to false.
• startCaptureManually - Set to true if you want to start capture manually using FS('start'). Fullstory will load but wait for a call to FS('start') to begin capturing. See Manually Delay Data Capture for more information. Defaults to false.
• assetMapId - Use this to set the current asset map id. See Asset Uploading for Web for more information.
• appHost - Use this to set the app host for displaying session urls. If using a version of Fullstory Relay, you may need to set appHost "app.fullstory.com" or "app.eu1.fullstory.com" depending on your region.

Ready Callback

The init function also accepts an optional readyCallback argument. If you provide a function, it will be invoked when the Fullstory session has started. Your callback will be called with one parameter: an object containing information about the session. Currently the only property is sessionUrl, which is a string containing the URL to the session.

import { init } from '@fullstory/browser';

init({ orgId }, ({ sessionUrl }) => console.log(`Started session: ${sessionUrl}`));

Initialization Examples

React

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import { init as initFullStory } from '@fullstory/browser';


initFullStory({ orgId: '<your org id here>' });

ReactDOM.render(<App />, document.getElementById('root'));

Angular with devMode enabled

import { Component } from '@angular/core';
import { init as initFullStory } from '@fullstory/browser';
import { environment } from '../environments/environment';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {

  constructor() {
    initFullStory({
      orgId: '<your org id here>',
      devMode: !environment.production,
    });
  }
}

Vue

import Vue from 'vue';
import App from './App.vue';
import { init as initFullStory, FullStory } from '@fullstory/browser';

initFullStory({ orgId: '<your org id here>' });
Vue.prototype.$FullStory = FullStory;

new Vue({
  render: h => h(App)
}).$mount('#app');

Vue 3

import { createApp } from 'vue';
import App from './App.vue';
import { init as initFullStory, FullStory } from '@fullstory/browser';

initFullStory({ orgId: '<your org id here>' });

const app = createApp(App);
app.config.globalProperties.$FullStory = FullStory;
app.mount('#app');

Using the SDK

Once FullStory is initialized, you can make calls to the FullStory SDK. See the developer documentation for more information.

Sending custom events

FullStory('trackEvent', {
  name: 'Subscribed',
  properties: {
    uid: '750948353',
    plan_name: 'Professional',
    plan_price: 299,
    plan_users: 10,
    days_in_trial: 42,
    feature_packs: ['MAPS', 'DEV', 'DATA'],
  },
  schema: {
    properties: {
      plan_users: 'int', // override default inferred "real" type with "int"
      days_in_trial: 'int', // override default inferred "real" type with "int"
    }
  }
});

NOTE: The inclusion of type suffixes - appending _str or _int to the end of properties - is no longer required. All custom properties are inferred on the server. To override any default inference, you can add a schema. See Custom Properties for more information.

Generating session replay links

const startOfPlayback = FullStory('getSession');
const playbackAtThisMomentInTime = FullStory('getSession', { format: 'url.now' });

Sending custom user properties

FullStory('setProperties', {
  type: 'user',
  properties: {
    displayName: 'Daniel Falko',
    email: '[e-mail]',
    pricing_plan: 'free',
    popup_help: true,
    total_spent: 14.50,
  },
});

For more information on sending custom user properties, view the Fullstory help article on Capturing custom user properties.

Sending custom page properties

FullStory('setProperties', {
  type: 'page',
  properties: {
    pageName: 'Checkout', // what is the name of the page?
    cart_size: 10, // how many items were in the cart?
    used_coupon: true, // was a coupon used?
  },
  schema: {
    properties: {
      cart_size: 'int', // override default inferred "real" type with "int"
    }
  }
});

For more information on setting page properties, view the Fullstory help article on Sending custom page data to Fullstory.
