JetBrains Teases Powerful New Features for WebStorm 2025.2
JetBrains has released the roadmap for WebStorm 2025.2 , giving developers a look at what’s coming in the next major update to its popular JavaScript and TypeScript IDE. Set for release in July, this version continues the trend of improving developer workflows, performance, and support for modern web tools.
This comes shortly after the WebStorm 2025.1 update rolled out in April — and the team is already collecting user feedback to shape future releases.
Enhanced Bun Support
One of the highlights in WebStorm 2025.2 is improved integration with Bun , the fast JavaScript runtime. If your project includes a bun.lockb file, WebStorm will now automatically detect it and suggest using Bun as the default package manager , eliminating the need for manual configuration. You’ll also be able to run files directly via Bun from the context menu — just like you would with Node.js.
Under-the-Hood TypeScript Improvements
The new service-powered type engine — a major internal overhaul of how WebStorm handles TypeScript types — is continuing to evolve. This change aims to significantly improve performance, especially in large-scale projects that use heavy frameworks or deeply nested component trees.
Specific enhancements include better tag and attribute completion in React (TypeScript) and Angular templates , along with fixes for edge cases involving third-party libraries. For example, issues like missing props from libraries such as motion are being addressed.
Modern CSS Features
WebStorm 2025.2 is expanding its support for the latest CSS standards. The update will recognize newer property values, recently introduced at-rules, and updates from the CSS Color Module , including support for color formats like color-mix().
In addition, JetBrains is fixing a long-standing issue where CSS variables weren’t resolving correctly inside language-injected code , a common scenario in CSS-in-JS setups.
Preparing for the Future of TypeScript
As Microsoft works on rebuilding the TypeScript compiler and language server in Go for better speed and scalability, JetBrains is laying the groundwork in WebStorm to ensure compatibility with these changes. While no visible effects will appear in the 2025.2 release, this foundation is critical for future updates.
Try It Early
If you’re eager to test these features ahead of the official launch, JetBrains invites users to join the WebStorm 2025.2 Early Access Program (EAP) . Keep in mind that EAP builds may be unstable, and some features could change or be removed before the final release.
