Load testing for TypeScript developers
Write performance tests with the productivity and type safety of TypeScript. Get compile-time checks, clearer code, and maintainable test suites using the language your team already knows.
Why TypeScript for load testing?
Catch issues earlier
TypeScript detects type mismatches, invalid function calls, and incorrect parameters while you’re writing tests, before execution. This reduces runtime surprises and shortens your debugging cycle.
Enhanced developer experience
Enjoy autocomplete, inline documentation, refactoring support, and error highlighting in your IDE. Write tests faster and with more confidence using the TypeScript tooling you already rely on.
Leverage existing TypeScript skills
Your team already knows TypeScript from frontend or backend development. Apply that knowledge directly to performance testing without learning new syntax or paradigms.

FAQ
Frequently asked questions about Gatling's TypeScript SDK
TypeScript provides compile-time error checking, intelligent code completion, and better refactoring capabilities. You'll catch configuration errors before running tests, get better IDE support, and write more maintainable test code with self-documenting type definitions.
Absolutely! Import any npm package or TypeScript library you need. This includes utility libraries like Lodash, date libraries like date-fns, crypto libraries, custom business logic, and any other packages from the npm ecosystem.
While TypeScript knowledge helps you get the most benefit, the SDK works with regular JavaScript too. You can start with JavaScript syntax and gradually adopt TypeScript features as you become more comfortable. The type definitions will guide you even if you're new to TypeScript.
The TypeScript SDK provides typed session management and data extraction. You can extract values from responses using JsonPath, regex, or CSS selectors with full type safety, and reuse them in subsequent requests with proper autocomplete support.
