Is your #NestJS app ready to handle thousands of users? 💪 High traffic? Typical performance tests won't cut it. Ensure your backend can scale under intense pressure for a smooth launch! That’s where #k6 comes in—a powerful, open-source tool designed to load test APIs, microservices, and websites. Why is load testing important? ✅ It shows how quickly your app responds to various user loads. ✅ Keeps your app stable and fast. ✅ Spots bottlenecks early. ✅ Ensures scalability as users grow. How do you start with k6 and ensure your API is robust? 🤔 1️⃣ Install k6: Use Homebrew, Linux packages, or Docker. 2️⃣ Set up your NestJS app: We'll use an e-commerce platform as an example, but you can apply this to any NestJS app. 3️⃣ Configure tests: Script the load, define users, and set success thresholds (e.g., 95% under 500ms).).

Developers often leave dead files in the codebase, thinking they might reuse them later, but in reality, those files rarely get touched again. If you're using Git, you can confidently remove such files since they’re always retrievable from history. To identify unused files, try running npx knip — it’s a quick way to tidy up your codebase. https://lnkd.in/dY7sEpks

For Angular dev, since Angular doesn't support runtime env variables out of the box, the default way of deploying an app into multiple environments is to have environment files in our apps. For each deployment env we would add an extra environment file ( environment.dev.ts, environment.staging.ts, environment.prod.ts, ...) things can get worse if we have multiple clients who are using the same app and each one of them needs his instance. I found this article that explains a workaround for having runtime env variables in a relatively clean and elegant way.
