@amplitude/plugin-session-replay-browser

Official Browser SDK plugin for session replay

Installation

This package is published on NPM registry and is available to be installed using npm and yarn.

# npm
npm install @amplitude/plugin-session-replay-browser

# yarn
yarn add @amplitude/plugin-session-replay-browser

Usage

This plugin works on top of Amplitude Browser SDK and adds session replay features to built-in features. To use this plugin, you need to install @amplitude/analytics-browser version v1.9.1 or later.

This plugin requires that default tracking for sessions is enabled. If default tracking for sessions is not enabled in the config, the plugin will automatically enable it.

1. Import Amplitude packages

• @amplitude/analytics-browser
• @amplitude/plugin-session-replay-browser

import * as amplitude from '@amplitude/analytics-browser';
import { sessionReplayPlugin } from '@amplitude/plugin-session-replay-browser';

2. Instantiate Session Replay plugin

The plugin must be registered with the amplitude instance via the following code. The plugin accepts an optional parameter which is an Object to configure the plugin based on your use case.

amplitude.init(API_KEY);
const sessionReplayTracking = sessionReplayPlugin({
  sampleRate: undefined
});

Options

Name	Type	Default	Description
sampleRate	number	undefined	Use this option to control how many sessions will be selected for replay collection. A selected session will be collected for replay, while sessions that are not selected will not. The number should be a decimal between 0 and 1, ie 0.4, representing the fraction of sessions you would like to have randomly selected for replay collection. Over a large number of sessions, 0.4 would select 40% of those sessions.

3. Install plugin to Amplitude SDK

amplitude.add(sessionReplayTracking);

Privacy

By default, the session replay will mask all inputs, meaning the text in inputs will appear in a session replay as asterisks: ***. You may require more specific masking controls based on your use case, so we offer the following controls:

1. Unmask inputs

In your application code, add the class .amp-unmask to any input whose text you'd like to have unmasked in the replay. In the session replay, it will be possible to read the exact text entered into an input with this class, the text will not be converted to asterisks.

2. Mask non-input elements

In your application code, add the class .amp-mask to any non-input element whose text you'd like to have masked from the replay. The text in the element, as well as it's children, will all be converted to asterisks.

3. Block non-text elements

In your application code, add the class .amp-block to any element you would like to have blocked from the collection of the replay. The element will appear in the replay as a placeholder with the same dimensions.
