Tracker Service

Tracking service to map user interactions using the Amplitude library.

Development aid tool

Amplitude Chrome Extension here.

Installation

yarn add @felipelealdefaria/tracker-service
# or
npm i @felipelealdefaria/tracker-service

Usage

import track from '@felipelealdefaria/tracker-service'

1) Initialize:

This is required before any other methods can be called.

track.init(params: InitParams): { success?: boolean | error?: boolean }

InitParams:
- apiKey: string
- userId?: string
- options?: {}
- callback?: () => unknown

See more options here.

2) Log Event:

Log event in Amplitude Dashboard.

track.log(params: LogParams): { success?: boolean | error?: boolean }

LogParams:
- eventName: string
- eventProperties?: {}
- timestamp?: number
- callback?: () => unknown

3) Set User Identification:

Identify current user:

track.setUserId(userId: string): { success?: boolean | error?: boolean }

4) Set User Properties:

Identify current user properties:

track.setUserProperties(userProperties: {}): { success?: boolean | error?: boolean }

5) Get Session Id:

Get current session id:

track.getSessionId(): { (success?: boolean | error?: boolean), sessionId: number | null }

6) New Session:

Verify if new session was created:

track.isNewSession(): { (success?: boolean | error?: boolean), isNewSession: boolean | null }

7) Clear User Properties:

Clear current user properties:

track.clearUserProperties(): { success?: boolean | error?: boolean }

8) Set Domain:

Sets a customer domain for the amplitude cookie. Useful if you want to support cross-subdomain tracking.

track.setDomain(domain: string): { success?: boolean | error?: boolean }

9) Set Track Off:

Sets whether to opt current user out of tracking.

track.setTrackOff(enable: boolean): { success?: boolean | error?: boolean }

10) Set Device Id:

Sets a custom deviceId for current user. Note: this is not recommended unless you know what you are doing (like if you have your own system for managing deviceIds). Make sure the deviceId you set is sufficiently unique (we recommend something like a UUID - see src/uuid.js for an example of how to generate) to prevent conflicts with other devices in our system.

track.setDeviceId(deviceId: string): { success?: boolean | error?: boolean }

11) Set Group:

Add user to a group or groups. You need to specify a groupType and groupName(s).

For example you can group people by their organization. In that case, groupType is "orgId" and groupName would be the actual ID(s). groupName can be a string or an array of strings to indicate a user in multiple gruups. You can also call setGroup multiple times with different groupTypes to track multiple types of groups (up to 5 per app).

track.setGroup(params: GroupParams): { success?: boolean | error?: boolean }

GroupParams:
- groupType: string
- groupName: string | string[]

12) Log Group:

Log an event with eventType, eventProperties, and groups. Use this to set event-level groups. Note: the group(s) set only apply for the specific event type being logged and does not persist on the user (unless you explicitly set it with setGroup).

track.logGroup(params: LogGroupParams): { success?: boolean | error?: boolean }

LogGroupParams:
- eventName: string
- eventProperties?: {}
- group?: {}
- callback?: () => unknown

Service's Architecture

Service created using the principles of Clean Architecture with the intention of facilitating maintenance and a possible exchange of lib used to trackers.
