@amplitude/analytics-node

What is @amplitude/analytics-node?

@amplitude/analytics-node is an npm package that allows you to integrate Amplitude's analytics capabilities into your Node.js applications. It provides functionalities for tracking events, identifying users, and setting user properties, which can help you understand user behavior and improve your product.

What are @amplitude/analytics-node's main functionalities?

Track Events

This feature allows you to track events that occur in your application. The code sample demonstrates how to log a 'user_signup' event with associated properties.

const amplitude = require('@amplitude/analytics-node');
const client = amplitude.init('YOUR_API_KEY');

client.logEvent({
  event_type: 'user_signup',
  user_id: 'user123',
  event_properties: {
    plan: 'premium'
  }
});

Identify Users

This feature allows you to identify users and set their properties. The code sample shows how to identify a user and set their email and name.

const amplitude = require('@amplitude/analytics-node');
const client = amplitude.init('YOUR_API_KEY');

client.identify({
  user_id: 'user123',
  user_properties: {
    $set: {
      email: '[e-mail]',
      name: 'John Doe'
    }
  }
});

Set User Properties

This feature allows you to set or update properties for a user. The code sample demonstrates how to set the age and gender properties for a user.

const amplitude = require('@amplitude/analytics-node');
const client = amplitude.init('YOUR_API_KEY');

client.identify({
  user_id: 'user123',
  user_properties: {
    $set: {
      age: 30,
      gender: 'male'
    }
  }
});

Official Amplitude SDK for Node.js

Installation

To get started with using Amplitude Node.js SDK, install the package to your project via NPM.

Using Node package

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

# npm
npm install @amplitude/analytics-node

# yarn
yarn add @amplitude/analytics-node

Usage

Initializing SDK

Initialization is necessary before any instrumentation is done. The API key for your Amplitude project is required.

amplitude.init(API_KEY);

Tracking an Event

Events represent how users interact with your application. For example, "Button Clicked" may be an action you want to note.

import { track } from '@amplitude/analytics-node';

// Track a basic event
track('Button Clicked');

// Track events with additional properties
const eventProperties = {
  selectedColors: ['red', 'blue'],
};
track('Button Clicked', eventProperties);

User Properties

User properties help you understand your users at the time they performed some action within your app such as their device details, their preferences, or language.

import { Identify, identify } from '@amplitude/analytics-node';

const event = new Identify();

// sets the value of a user property
event.set('key1', 'value1');

// sets the value of a user property only once
event.setOnce('key1', 'value1');

// increments a user property by some numerical value.
event.add('value1', 10);

// pre inserts a value or values to a user property
event.preInsert('ab-tests', 'new-user-test');

// post inserts a value or values to a user property
event.postInsert('ab-tests', 'new-user-test');

// removes a value or values to a user property
event.remove('ab-tests', 'new-user-test')

// sends identify event
identify(event);

prepend/append

• append will append a value or values to a user property array.
• prepend will prepend a value or values to a user property.

User Groups

import { setGroup } from '@amplitude/analytics-node';

// set group with single group name
setGroup('orgId', '15');

// set group with multiple group names
setGroup('sport', ['soccer', 'tennis']);

Group Identify

This feature is only available to Growth and Enterprise customers who have purchased the Accounts add-on.

Use the Group Identify API to set or update properties of particular groups. However, these updates will only affect events going forward.

import { Identify, groupIdentify } from '@amplitude/analytics-node';

const groupType = 'plan';
const groupName = 'enterprise';
const identity = new Identify()
identity.set('key1', 'value1');

groupIdentify(groupType, groupName, identity);

Track Revenue

Revenue instances will store each revenue transaction and allow you to define several special revenue properties (such as 'revenueType', 'productIdentifier', etc.) that are used in Amplitude's Event Segmentation and Revenue LTV charts. These Revenue instance objects are then passed into revenue to send as revenue events to Amplitude. This allows us to automatically display data relevant to revenue in the platform. You can use this to track both in-app and non-in-app purchases.

import { Revenue, revenue } from '@amplitude/analytics-node';

const event = new Revenue()
  .setProductId('com.company.productId')
  .setPrice(3.99)
  .setQuantity(3);

revenue(event);

Callback

All asynchronous API are optionally awaitable through a specific Promise interface. This also serves as callback interface.

// Using async/await
const results = await track('Button Clicked').promise;
result.event; // {...} (The final event object sent to Amplitude)
result.code; // 200 (The HTTP response status code of the request.
result.message; // "Event tracked successfully" (The response message)

// Using promises
track('Button Clicked').promise.then((result) => {
  result.event; // {...} (The final event object sent to Amplitude)
  result.code; // 200 (The HTTP response status code of the request.
  result.message; // "Event tracked successfully" (The response message)
});
