Hey everyone! 👋

I'd like to share an open-source package I recently developed called nestjs-metrics-reporter. It's designed to make metrics reporting in NestJS as simple and seamless as possible.

Why Did I Create This?

When using other metrics libraries, I found that the dependency injection setup and boilerplate often got in the way more than they helped. Because of this, I wrote a zero-dependency-injection alternative to make reporting metrics from anywhere in your codebase easier.

I wrote about the motivation and technical details in more depth in my Medium article Avoid Prometheus Mess in NestJS

Key Features

• No Dependency Injection – Global static ReporterService for clean, portable code.
• Effortless Integration – Zero-setup, start tracking metrics instantly.
• Support for Pushgateway – Push batch job metrics effortlessly.
• Designed for Simplicity – Spend time coding, rather than dealing with complex configurations.

How It Works

With a minimal setup in your AppModule, you'll start reporting metrics like counters, gauges, histograms, and summaries in no time:

1. Install the package:

npm install nestjs-metrics-reporter

2. Configure the module:

ReporterModule.forRoot({
   defaultMetricsEnabled: true,
   defaultLabels: {
     app: 'my-app',
   },
}),

3. Report metrics anywhere in your application:

ReporterService.gauge('active_users', 42, { region: 'us-east-1' });

I'd be happy to hear your feedback! Feel free to dive in, open issues, or send PRs my way.
