During the extract refactoring, you will be prompted to provide a meaningful name. Source code fragments can be extracted into a new method, or into a new function at various different scopes. (Windows, Linux Ctrl+.)) to see available refactorings. Select the source code you'd like to extract and then click on the lightbulb in the gutter or press ( ⌘. (Windows, Linux Ctrl+.) keyboard shortcut. You can still open Quick Fixes through Quick Fix command and ⌘. Note: If you prefer to not see the Code Action lightbulb in your editor, you can disable lightbulbs with the setting. If you'd just like to see refactorings without Quick Fixes, you can use the Refactor command ( ⌃⇧R (Windows, Linux Ctrl+Shift+R)). (Windows, Linux Ctrl+.) will display Quick Fixes and refactorings.

Clicking on the Code Action lightbulb or using the Quick Fix command ⌘. An available Code Action is announced by a lightbulb near the source code when the cursor is on a squiggle or selected text region. In VS Code, Code Actions can provide both refactorings and Quick Fixes for detected issues (highlighted with green squiggles). Code Actions = Quick Fixes and refactorings

The UI and commands for refactoring are the same across languages, and in this topic we'll demonstrate refactoring support with the TypeScript language service.

Refactoring support for other programming languages is provided through VS Code extensions that contribute language services. Refactorings are provided by a language service and VS Code has built-in support for TypeScript and JavaScript refactoring through the TypeScript language service. Visual Studio Code supports refactoring operations (refactorings) such as Extract Method and Extract Variable to improve your code base from within your editor.įor example, a common refactoring used to avoid duplicating code (a maintenance headache) is the Extract Method refactoring, where you select source code that you'd like to reuse elsewhere and pull it out into its own shared method. Source code refactoring can improve the quality and maintainability of your project by restructuring your code while not modifying the runtime behavior.
