Mises à jour de 2026.2

Fonctionnalités

Key highlights

• TypeScript 7 support for faster workflows with large codebases - Large TypeScript codebases don't have to feel slow. TypeScript 7 rewrites the compiler and language server in Go, and the difference is noticeable immediately. In testing, project load time on the Kibana codebase dropped from ~12 seconds to ~3 seconds, which means editor responsiveness has improved roughly fourfold. WebStorm 2026.2 supports TypeScript 7 as the default for projects already using it, with an opt-in upgrade path for earlier versions - no full project migration required.
• Agent skills manager - Agents are only as useful as the context they have. Without knowledge of your frameworks, conventions, and tooling, you may end up needing to re-explain the same setup in every new chat window. Agent skills fix that. Install them once in WebStorm, and your agents carry that domain knowledge across every project and session. WebStorm 2026.2 features the new skills manager, a dedicated place to view and manage your agent skills. You can also expand the built-in library with external registries like public GitHub repositories, or let WebStorm import skills you've already set up for Claude Code or Codex.
• Native GitHub Copilot integration - If your team already uses GitHub Copilot, you no longer need a separate plugin or registry setup to bring it into WebStorm. Copilot is now a natively integrated agent. This is the result of a direct partnership between JetBrains and Microsoft. You can access Copilot from the AI chat's agent picker after signing in with your GitHub account. It's tested alongside the IDE and avoids configuration drift and version mismatches. A separate GitHub Copilot subscription is required.

Framework and ecosystem updates

• React Buddy: Full support for React 19 - React Buddy is a WebStorm plugin (available on JetBrains Marketplace) that brings visual component tooling to your React workflow in the IDE: component palettes, interactive previews, and Storybook story creation. If you migrated to React 19 early, you probably noticed the plugin didn't keep up. In WebStorm 2026.2, React Buddy fully supports React 19.
• Vue - Vue support has been updated with Vue language server 3.0 integration, improving compatibility with the latest tooling and fixing reliability issues, including incorrect hover types, stack overflows, and plugin-loading problems.
• Svelte - WebStorm now bundles an updated Svelte language server and TypeScript plugin, adds support for SvelteKit shared hooks (reroute, init, and transport), and improves Svelte 5 named snippet handling. Multiple parsing, highlighting, and CSS selector issues have also been resolved.
• Astro, Prisma, and Angular - 2026.2 bundles updated language servers for Astro and Prisma. Angular workflows have been improved thanks to fixes for slow or missing TypeScript/Angular error updates, as well as more efficient dependency processing.
• CSS, Sass, SCSS, and Less - Style sheet refactoring is now more reliable. SCSS and Sass glob imports and absolute import paths no longer rewrite unexpectedly. Color previews for modern CSS functions like color() and color-mix() now work across Sass, SCSS, and Less. CSS syntax data has been updated, and a false positive around nested selectors has been fixed.
• Debugging, test runners, and Node.js - In WebStorm 2026.2, debugging is more predictable. You can now disable source maps, Ctrl+Shift+Click starts a debug session correctly, and fixes are available for JavaScript debug errors. Additionally, Cypress and Playwright run more reliably, and Playwright no longer freezes in affected scenarios. Node.js handling has also improved. WebStorm now reads environment variables from login interactive shells, detects runtimes in native Dev Containers, and fixes empty dependency data and cases where node_modules was incorrectly skipped as a content root.

Performance and quality improvements

• Performance and stability - This release addresses a broad set of freezes and regressions affecting NPM run configuration checks, package.json completion, Node.js interpreter detection, Tailwind server startup and web-types processing. It also fixes typing, indexing, reduces memory usage in JavaScript handling, and speeds up test framework search.
• User experience - WebStorm 2026.2 also adds notable UX improvements. Search Everywhere now preserves its scope across restarts, Markdown support includes footnotes and Mermaid diagrams, and you can customize double-key shortcuts in the keymap. The IDE now detects prunable Git worktrees and improves worktree support in WSL environments, bookmarks persist when switching branches, and you can drag and drop a file into the terminal to insert its path.
