Performance Testing APIs
Explore tools and strategies for performance testing your NestJS APIs to identify bottlenecks and ensure scalability.
Why Performance Matters
Ever used a slow app? Performance testing helps prevent that! It's about checking how your API behaves under various workloads.
We want to ensure our NestJS APIs are fast, responsive, and reliable, even when many users access them simultaneously. This is crucial for a good user experience and system stability.
Measuring API Health
When performance testing, we look at specific metrics:
- Latency: The time taken for a request to complete. Lower is better!
- Throughput: The number of requests processed per second. Higher is better!
- Error Rate: The percentage of failed requests. Aim for zero.
- Resource Utilization: How much CPU/Memory your server uses.
These metrics help us understand our API's strengths and weaknesses.
