How to clean the VS Code cache to improve the development experience: Clean the extension cache: Close VS Code and delete the extension directory (Linux/macOS: ~/.vscode/extensions; Windows: %APPDATA%\Code\User\extensions) Clean the workspace cache: Delete the .vscode directory in the root directory of the project. Clean other temporary files: Delete the system temporary file directory according to the operating system (Windows: %temp%; macOS: /tmp; Linux: /tmp)

How to clean up VS Code cache and improve your development experience

VS Code is an excellent code editor, but over time, cache files accumulation may cause it to run slower and even have some weird problems. Cleaning up caches can effectively solve these problems and restore the best performance of VS Code. This article will take you through how to safely and effectively clean VS Code's cache, and share some experience and skills I have accumulated during use.

VS Code's cache mainly includes several aspects: extended cache, workspace cache and some temporary files. They store the running data of the extension, project configuration information, and resources temporarily generated by the editor. These caches exist to improve performance, such as quickly loading extensions or projects, but excessive caches can backfire.

Cleaning up extension cache: Some extensions may have bugs, or conflicts with other extensions, causing VS Code to run slowly or even crash. Cleaning up extended caches is an effective way to solve this type of problem. The method is very simple. Turn off VS Code directly, and then delete the ~/.vscode/extensions directory (Linux/macOS) or %APPDATA%\Code\User\extensions directory (Windows). Open VS Code again and all extensions will reload, and the problem is likely to be solved. Note: This resets the configuration of all extensions, so it is best to back up important settings before cleaning.

Clean the workspace cache: Each workspace will generate some cache files to store project-related settings and status. If your project is larger or the configuration is complicated, the workspace cache may become large. The way to clean the workspace cache is to delete the .vscode directory (located in your project root directory). This will clear the cache of the workspace, but will not affect your code file. If you encounter some difficult-to-explain errors in a project, trying to clean the workspace cache may solve the problem. I once encountered the problem of automatic code completion failure in a large React project. After cleaning the workspace cache, it returned to normal.

Clean up other temporary files: VS Code also generates some other temporary files, which are usually located in the system's temporary file directory. Cleaning these files requires operations based on your operating system. Under Windows, you can search for %temp% and delete unnecessary files; under macOS, you can find the /tmp directory; under Linux, it is usually the /tmp directory. However, please be careful not to delete files that you don’t know the purpose, so as not to affect the system operation. I personally do not recommend cleaning these temporary files frequently unless you have obvious insufficient disk space.

Some debugging tips and best practices:

• Regular Cleanup: I recommend cleaning the cache of VS Code every once in a while (e.g. weekly or biweekly) to keep it running optimally.
• Monitor disk space: If you find that VS Code takes up too much disk space, you can consider cleaning the cache.
• Identify Problem Extension: If an extension causes VS Code to run slowly, you can try to disable or uninstall the extension.
• Using Resource Monitor: Use the system's resource monitor (such as Windows Task Manager or macOS Activity Monitor) to view the memory and CPU usage of VS Code to help you identify performance bottlenecks.

Cleaning up VS Code cache is an easy but effective way to optimize. By sanitizing cache reasonably and following some best practices, you can significantly improve VS Code performance and avoid some potential problems. Remember to operate with caution and back up important data, which will ensure that your development process is smooth.
