What’s New in WebStorm 2025.1

JetBrains AI has received a major upgrade, bringing both AI Assistant and Junie under a single subscription. With this release, AI features are now free in JetBrains IDEs, including unlimited code completion, support for local models, and credit-based access to cloud-hosted features, including the coding agent. A new subscription system makes it easy to scale up with the AI Pro and AI Ultimate tiers. For more information check out this page.

JetBrains AI Assistant is advancing its line of models. We’ve added support for Claude 3.7 Sonnet, now provisioned in Amazon Bedrock. This means you’ll benefit from sharper responses, faster insights, and an even smoother experience. AI Assistant’s lineup of OpenAI models now includes o1, o1-mini, o3-mini, and GPT-4.1 (сoming soon).

WebStorm now automatically detects the appropriate test framework when generating unit tests with AI-powered assistance. This improvement ensures that tests are created using the correct framework for your project, reducing the need for manual adjustments and making the test generation process more seamless and efficient.

WebStorm also ensures that AI-generated unit tests follow existing naming conventions in your project.

For the 2025.1 release, we’ve focused on improving AI-based completion in the context of web framework components. These changes affect local full-line code completion as well as cloud-based completion suggestions.

AI Assistant gives you the flexibility to work with local models in offline mode or leverage cloud-based AI processing. Now it supports offline mode, allowing you to work without an internet connection while still benefiting from AI-powered coding assistance. Use local models via Ollama or LM Studio for chat, code generation, commit messages, inline documentation, and more.

WebStorm now supports signal queries introduced in Angular 17.2, providing better code insight and navigation for this modern reactive approach to dependency injection. With this update, WebStorm ensures accurate type inference for signal queries, improves code completion within query expressions, and enhances navigation between signals and their references.

WebStorm now provides code completion and generation support for FormGroup, FormArray, FormControl, and FormBuilder in Angular's reactive forms. This update makes it easier to define and manage form structures, reducing manual effort and improving development speed. With better autocompletion and quick-fixes, working with reactive forms is now more intuitive and efficient.

WebStorm now offers improved object property suggestions for property bindings, making it easier to work with bound component properties. You'll get more accurate autocompletion and validation when defining bindings in templates, reducing errors, and streamlining development in Angular applications.

WebStorm now makes it easier to refactor between inline and separate templates in Angular components. With just a quick action, you can convert an inline template to a separate file (templateUrl) and back again, streamlining your workflow and improving code organization.

WebStorm now automatically generates run configurations for Next.js projects, making it easier to set up and debug full-stack applications.

WebStorm 2025.1 introduces a floating toolbar that appears when you press Alt+Enter or select code. This toolbar offers quick access to AI features, refactoring, code reformatting, and Surround With actions.

Creating a new file is now more convenient. You can access the popup listing available file templates directly from the Project window toolbar via the + icon, and the search field lets you quickly filter and find the file type you need.

WebStorm now makes it easier to start new Vue projects with Nuxt CLI (nuxi) integration in the New Project wizard, allowing for a smoother setup experience.

We've also improved support for Vue’s global properties by correctly resolving custom properties added through module augmentation. Additionally, issues with autocompletion and auto-import for packaged components declared with __VLS_WithTemplateSlots have been fixed, ensuring a more reliable development experience in Vue projects.

WebStorm now respects Prettier configurations on a per-subproject basis, ensuring that each part of your monorepo or multi-project setup follows its own formatting rules. This improvement provides greater flexibility and consistency when working across different codebases with varying style requirements.
