Let’s take a brief look at some of the most interesting improvements in v2023.3.

Key highlights

• JetBrains AI Assistant: the AI Assistant plugin has received several significant updates in the 2023.3 release. You can look forward to enhanced code generation directly within the editor, a context-aware AI chat that answers project-related queries, and project-aware AI actions that provide more comprehensive results. You can check out the latest updates to the AI Assistant in this blog post.
• Improvements for Angular: WebStorm 2023.3 is turning out to be a huge release for our Angular support. The release includes better support for strict template type checking, signal handling, initial Angular v17 control-flow syntax support, various new quick-fixes, and more.
• Updates to the Svelte plugin: We’ve added built-in support for the TypeScript plugin to provide consistent highlighting and quick documentation for TypeScript files in your Svelte projects. There’s also a more stable way to import components automatically on completion, copy-paste, and Alt+Enter / ⌥Enter. Additionally, support for zero-effort type safety was expanded to cover TypeScript files, too.
• Improvements for Vue 3: We’ve added new support for Vue 3 to provide completion and Rename refactoring for defineSlots and completion for properties with defineExpose. Furthermore, required imports for components will now be added based on the name specified by the defineOptions function.
• Cypress and Playwright support: WebStorm 2023.3 brings new capabilities for testing your JavaScript code. Cypress and Playwright tests are now automatically detected and can be run from a Run icon in the editor. The support also includes the ability to explore the results and find issues by navigating the test tree. You can extend the support with the Test Automation plugin, which provides an embedded browser and advanced code insight.
• Initial support for the Node.js test runner: WebStorm 2023.3 introduces support for the built-in Node.js test runner. Tests declared with the node:test API are now recognized, and you can run and debug them via gutter icons. This support is still in its initial implementation and has some limitations, but you are able to write tests for JavaScript code directly from your code, without having to install any packages.
