Performance Testing (k6, Grafana, Prometheus, Docker, TypeScript) overview

A performance and load testing platform centered on k6 for scripting realistic user scenarios in TypeScript/JavaScript, with Prometheus collecting test metrics and Grafana rendering real-time dashboards of throughput, latency percentiles, and error rates. Docker containers enable distributed load generation from multiple workers. Tests run in CI via GitHub Actions with automatic regression detection against baseline thresholds. Targeted at performance engineers validating SLOs before release. Locust serves as an alternative for Python-native teams. The tradeoff is that k6 lacks built-in browser rendering — teams needing real browser performance metrics must supplement with Playwright or Lighthouse.
