The Mixpanel npm package is a powerful tool for integrating Mixpanel's analytics and user tracking capabilities into your Node.js applications. It allows you to track events, create user profiles, and send data to Mixpanel for analysis.
Track Events
This feature allows you to track events that occur in your application. You can specify the event name and any properties associated with the event.
const Mixpanel = require('mixpanel');
const mixpanel = Mixpanel.init('YOUR_API_KEY');
mixpanel.track('Event Name', {
distinct_id: 'unique_user_id',
property1: 'value1',
property2: 'value2'
});Create User Profiles
This feature allows you to create and update user profiles in Mixpanel. You can set various properties for a user, such as their name and email address.
const Mixpanel = require('mixpanel');
const mixpanel = Mixpanel.init('YOUR_API_KEY');
mixpanel.people.set('unique_user_id', {
$first_name: 'John',
$last_name: 'Doe',
$email: 'john.doe@example.com'
});Increment User Properties
This feature allows you to increment numerical properties of a user profile. For example, you can keep track of how many times a user has logged in.
const Mixpanel = require('mixpanel');
const mixpanel = Mixpanel.init('YOUR_API_KEY');
mixpanel.people.increment('unique_user_id', 'login_count');Segment is a customer data platform that helps you collect, clean, and control your customer data. It offers similar event tracking and user profile management capabilities as Mixpanel, but also integrates with a wide range of other analytics and marketing tools.
Amplitude is an analytics platform that provides in-depth insights into user behavior. It offers event tracking and user profile management similar to Mixpanel, but is known for its advanced analytics and reporting features.
Heap is an analytics tool that automatically captures all user interactions with your application. It offers similar event tracking and user profile management capabilities as Mixpanel, but focuses on providing a more automated and comprehensive data collection process.
This library provides many of the features in the official JavaScript mixpanel library. It is easy to use, and fully async. It is intended to be used on the server (it is not a client module). The in-browser client library is available at https://github.com/mixpanel/mixpanel-js.
npm install mixpanel
// grab the Mixpanel factory
var Mixpanel = require('mixpanel');
// create an instance of the mixpanel client
var mixpanel = Mixpanel.init('<YOUR_TOKEN>');
// initialize mixpanel client configured to communicate over http instead of https
var mixpanel = Mixpanel.init('<YOUR_TOKEN>', {
protocol: 'http',
});
// turn off keepAlive (reestablish connection on each request)
var mixpanel = Mixpanel.init('<YOUR_TOKEN>', {
keepAlive: false,
});
// pass the custom logger (default is console)
var mixpanel = Mixpanel.init('<YOUR_TOKEN>', {
debug: true,
logger: pinoLogger, // or bunyan, or any other logger that implements the same interface
});
// track an event with optional properties
mixpanel.track('my event', {
distinct_id: 'some unique client id',
as: 'many',
properties: 'as',
you: 'want'
});
mixpanel.track('played_game');
// set an IP address to get automatic geolocation info
mixpanel.track('my event', {ip: '127.0.0.1'});
// track an event with a specific timestamp (up to 5 days old;
// use mixpanel.import() for older events)
mixpanel.track('timed event', {time: new Date()});
// create or update a user in Mixpanel Engage
mixpanel.people.set('billybob', {
$first_name: 'Billy',
$last_name: 'Bob',
$created: (new Date('jan 1 2013')).toISOString(),
plan: 'premium',
games_played: 1,
points: 0
});
// create or update a user in Mixpanel Engage without altering $last_seen
// - pass option $ignore_time: true to prevent the $last_seen property from being updated
mixpanel.people.set('billybob', {

games_played: 1
}, {
$ignore_time: true
});
// set a user profile's IP address to get automatic geolocation info
mixpanel.people.set('billybob', {

});
// set a user profile's latitude and longitude to get automatic geolocation info

}, {
$latitude: 40.7127753,
$longitude: -74.0059728
});
// set a single property on a user
mixpanel.people.set('billybob', 'plan', 'free');
// set a single property on a user, don't override
mixpanel.people.set_once('billybob', 'first_game_play', (new Date('jan 1 2013')).toISOString());
// increment a numeric property
mixpanel.people.increment('billybob', 'games_played');
// increment a numeric property by a different amount
mixpanel.people.increment('billybob', 'points', 15);
// increment multiple properties
mixpanel.people.increment('billybob', {'points': 10, 'games_played': 1});
// append value to a list
mixpanel.people.append('billybob', 'awards', 'Great Player');
// append multiple values to a list
mixpanel.people.append('billybob', {'awards': 'Great Player', 'levels_finished': 'Level 4'});
// merge value to a list (ignoring duplicates)
mixpanel.people.union('billybob', {'browsers': 'ie'});
// merge multiple values to a list (ignoring duplicates)
mixpanel.people.union('billybob', {'browsers': ['ie', 'chrome']});
// record a transaction for revenue analytics
mixpanel.people.track_charge('billybob', 39.99);
// clear a users transaction history
mixpanel.people.clear_charges('billybob');
// delete a user
mixpanel.people.delete_user('billybob');
// delete a user in Mixpanel Engage without altering $last_seen or resolving aliases
// - pass option $ignore_time: true to prevent the $last_seen property from being updated
// (useful if you subsequently re-import data for the same distinct ID)
mixpanel.people.delete_user('billybob', {$ignore_time: true, $ignore_alias: true});
// Create an alias for an existing distinct id
mixpanel.alias('distinct_id', 'your_alias');
// all functions that send data to mixpanel take an optional
// callback as the last argument
mixpanel.track('test', function(err) { if (err) throw err; });
// track multiple events at once
mixpanel.track_batch([
{
event: 'recent event',
properties: {
time: new Date(),
distinct_id: 'billybob',
gender: 'male'
}
},
{
event: 'another recent event',
properties: {
distinct_id: 'billybob',
color: 'red'
}
}
]);
// import an old event
var mixpanel_importer = Mixpanel.init('valid mixpanel token', {
secret: 'valid api secret for project'
});
// needs to be in the system once for it to show up in the interface
mixpanel_importer.track('old event', { gender: '' });
mixpanel_importer.import('old event', new Date(2012, 4, 20, 12, 34, 56), {
distinct_id: 'billybob',
gender: 'male'
});
// import multiple events at once
mixpanel_importer.import_batch([
{
event: 'old event',
properties: {
time: new Date(2012, 4, 20, 12, 34, 56),
distinct_id: 'billybob',
gender: 'male'
}
},
{
event: 'another old event',
properties: {
time: new Date(2012, 4, 21, 11, 33, 55),
distinct_id: 'billybob',
color: 'red'
}
}
]);
Where is mixpanel.identify()?
mixpanel-node is a server-side library, optimized for stateless shared usage; e.g.,
in a web application, the same mixpanel instance is used across requests for all users.
Rather than setting a distinct_id through identify() calls like Mixpanel client-side
libraries (where a single Mixpanel instance is tied to a single user), this library
requires you to pass the distinct_id with every tracking call. See
https://github.com/mixpanel/mixpanel-node/issues/13.
How do I get or set superproperties?
See the previous answer: the library does not maintain user state internally and so has no concept of superproperties for individual users. If you wish to preserve properties for users between requests, you will need to load these properties from a source specific to your app (e.g., your session store or database) and pass them explicitly with each tracking call.
