Mastering load testing with Gatling’s JavaScript SDK

Modern web applications rely on real-time interactions, event-driven architectures, and a wide variety of protocols. But for most JavaScript developers, load testing often feels like switching gears: different languages, different tools, and extra overhead.

Gatling’s JavaScript SDK removes that friction. With full TypeScript support and functionality equivalent to our traditional Java/Scala SDKs, it gives JS developers the power to write complex, production-grade load tests directly in their native language.

In this 45-minute session, Shaun Brown, Product Marketing Managerat Gatling, will demonstrate how the JS SDK lets you:

• Craft flexible, reusable load tests in JavaScript or TypeScript
• Test multiple protocols like WebSocket, SSE, and MQTT with ease
• Run and scale tests on Gatling Enterprise Edition for advanced reporting, collaboration, and observability integration

Shaun will walk through a live demo showing how simple it is to set up and run a test, including a real example with MQTT. You’ll also learn how enterprise-grade load testing capabilities fit naturally into your JS development workflow, without context switching.
