A progressive Node.js framework for building efficient and scalable server-side applications.

Description

Segment Analytics module for Nest

Installation

To begin using it, we first install the required dependencies.

``bash
$ npm install nestjs-segment-analytics @segment/analytics-node
`

Getting Started

Once the installation process is complete, we can import the SegmentAnalyticsModule. Typically, we'll import it into the root AppModule and control its behavior using the .register() static method. During this step, the segment Analytics instance is created. Later, we'll see how we can access the Analytics instance our other feature modules.

`typescript
import { SegmentAnalyticsModule } from 'nestjs-segment-analytics';

@Module({
imports: [
SegmentAnalyticsModule.register({
writeKey: '',
}),
],
providers: [AppService],
})
export class AppModule {}
`

Use module globally

When you want to use SegmentAnalyticsModule in other modules, you'll need to import it (as is standard with any Nest module). Alternatively, declare it as a global module by setting the options object's isGlobal property to true, as shown below. In that case, you will not need to import SegmentAnalyticsModule in other modules once it's been loaded in the root module (e.g., AppModule).

`typescript
SegmentAnalyticsModule.register({
isGlobal: true,
});
`

> Hint
> The register method accepts all values from AnalyticsSettings and passes it to the Analytics constructor, you can see all options here.

Using the ConfigService

To access our segment Analytics instance, we first need to inject Analytics. As with any provider, we need to import its containing module - the SegmentAnalyticsModule - into the module that will use it (unless you set the isGlobal property in the options object passed to the SegmentAnalyticsModule.register() method to true). Import it into a feature module as shown below.

`typescript
// feature.module.ts
@Module({
imports: [SegmentAnalyticsModule],
// ...
})
`

Then we can inject it using standard constructor injection:

`typescript
import { InjectAnalytics } from 'nestjs-segment-analytics';
import { Analytics } from '@segment/analytics-node';
// ...

constructor(@InjectAnalytics() private analytics: Analytics) {}
`

> HINT
> The Analytics is imported from the @segment/analytics-node package.

And use it in our class:

`typescript
await this.analytics.track({
userId,
event: 'Create Item',
properties: { itemId: '564897' },
});
``
