## Production data: NestJS Observe
This app's production telemetry - traces, errors, logs and metrics - goes to [NestJS Observe](https://observe.nestjs.com). Until `ObserveModule` is registered in `src/app.module.ts`, nothing is sent: `npx @nestjs/observe link` sets it up in one step - it installs `@nestjs/observe`, wires it into the app, and writes the key pair (`OBSERVE_APP_KEY`, `OBSERVE_APP_SECRET`) to `.env`.
When a task depends on how the app behaves in production - an error users hit, a slow endpoint, a failing job, whether a release made things worse - work from that data, not from the code alone:
- The Observe MCP server answers those questions directly: errors with their traces and logs, slow operations, jobs, and what a release changed (`find_regressions`, `diff_release`). It is included on the Pro plan and above. In Claude Code: `claude mcp add observe --transport http https://observe-api.nestjs.com/mcp`, and the client opens a browser to approve. Other clients: https://www.observe.nestjs.com/documentation/mcp
- Without it, the user can open the request or error in the Observe dashboard and click **Copy agent prompt**, which hands over that page's trace, stack and logs as text.

## Description
[Nest](https://github.com/nestjs/nest) framework TypeScript starter repository.
## Project setup
```bash
$ npm install
```
## Compile and run the project
```bash
# development
$ npm run start
# watch mode
$ npm run start:dev
# production mode
$ npm run start:prod
```
## Run tests
```bash
# unit tests
$ npm run test
# e2e tests
$ npm run test:e2e
# test coverage
$ npm run test:cov
```
## Deployment
When you're ready to deploy your NestJS application to production, there are some key steps you can take to ensure it runs as efficiently as possible. Check out the [deployment documentation](https://docs.nestjs.com/deployment) for more information.
If you are looking for a cloud-based platform to deploy your NestJS application, check out [Mau](https://mau.nestjs.com), our official platform for deploying NestJS applications on AWS. Mau makes deployment straightforward and fast, requiring just a few simple steps:
```bash
$ npm install -g @nestjs/mau
$ mau deploy
```
With Mau, you can deploy your application in just a few clicks, allowing you to focus on building features rather than managing infrastructure.
## Observability
In production applications, observability is essential for understanding how your system behaves, detecting issues early, and maintaining reliable performance.
[NestJS Observe](https://observe.nestjs.com) automatically instruments your NestJS application, giving you deep visibility into your system with minimal setup:
- **Distributed tracing:** Follow requests across services and understand how they flow through your system.
- **Waterfall analysis:** Visualize request execution and identify slow operations, bottlenecks, and unexpected delays.
- **Performance analysis:** Analyze application performance in real time and quickly pinpoint areas that need optimization.
- **Metrics:** Track key application and infrastructure metrics to understand system health and performance trends.
- **Logging:** Centralize and correlate logs with traces and other telemetry to make debugging easier.
- **Error tracking:** Detect errors quickly and investigate their root causes with the surrounding context.
- **SLA monitoring:** Track service-level objectives and identify when your application is approaching or exceeding defined thresholds.
- **Alarms and alerts:** Set up alerts for critical errors, performance degradation, SLA violations, and other anomalies so your team can react quickly.
To add it to this project, run this and approve the code it prints at [observe.nestjs.com/link](https://observe.nestjs.com/link) - signing up for free if you have no account:
```bash
$ npx @nestjs/observe link
```
It installs `@nestjs/observe`, wires it into `AppModule` and `main.ts`, and writes the app key and secret into `.env`, which every `nest start` script (`start`, `start:dev`, `start:debug`) then loads. In production, set `OBSERVE_APP_KEY` and `OBSERVE_APP_SECRET` in the environment instead.
Or do it by hand:
```bash
$ npm install @nestjs/observe
```
Then follow the [setup guide](https://docs.nestjs.com/observability/sdk) - it takes a single import and an app key.
The free plan needs no payment details and covers 300,000 events a month. You can also browse the [live demo](https://www.observe-demo.nestjs.com/dashboard) first - the whole dashboard over a busy service's data, with nothing to install.
## Resources
