WebStorm 2026.2 adds stable TypeScript 7 support for Angular and React with no migration required
↗
WebStorm 2026.2 ships stable TypeScript 7 support powered by a Go-based language engine, delivering faster coding assistance for Angular and React projects without requiring teams to migrate their existing TypeScript version.
The Go-based engine in TypeScript 7 reportedly delivers up to 10x faster compilation than the Node.js-based predecessor, with WebStorm's tests on the Kibana codebase showing project load times dropping from around 12 seconds to 3 seconds. This matters because IDEs must rethink how they integrate with TypeScript at the language-service level, and WebStorm has built native support rather than relying on the existing plugin layer.

TypeScript 7 replaces the Node.js-based language service with a Go-based engine that Microsoft publications report is up to 10x faster.
WebStorm 2026.2.2 provides stable TypeScript 7 support for Angular by shipping its own template transpiler ported to Kotlin, even though neither the Angular compiler nor VS Code supports TypeScript 7 yet.
React TypeScript 7 support is stable out of the box, while Vue support is still in progress with a Kotlin transpiler port coming soon.
