Automatically saving in VS Code is a very practical feature that can avoid the hassle of saving files manually and frequently. By default, VS Code is turned off automatically, but can be turned on with just a simple setting.

How to enable automatic save in VS Code?

To enable the autosave function, you only need to modify one option in the settings. You can do it in the following ways:

• Open the VS Code settings (can be accessed via the menu bar File > Preferences > Settings or the shortcut key Ctrl , ).
• Enter auto save in the search box.
• Change the value of Files: Auto Save from the default off afterDelay or other mode you want.

After this setting, the editor will automatically save the current file after you stop typing for a period of time.

What are the differences between different modes of automatic saving?

VS Code provides multiple automatic save options, and different modes are suitable for different usage scenarios:

• off : The default state needs to be saved manually.
• afterDelay : Automatically save after you stop typing for a period of time. The delay time is controlled by another setting item files.autoSaveDelay . The default is 1000 milliseconds (i.e. 1 second).
• onFocusChange : Triggers save when you click on another program or editor window.
• onWindowChange : Save when switching windows.

If you want to minimize manual saving operations, it is recommended to use afterDelay mode. It won't be saved too often and it won't affect performance.

Can I modify it directly in the settings file?

In addition to adjusting settings through the graphical interface, you can also directly edit the VS Code configuration file settings.json , which is more intuitive and convenient for backup.

• Open the Command Panel (Shortcut Ctrl Shift P ), enter and select Preferences: Open Settings (JSON) .
• Add the following line to the open JSON file:

 "files.autoSave": "afterDelay"

You can replace it with other modes you want to use according to your habits. This modification method is more suitable for users who are familiar with the configuration file structure and is also convenient for synchronization to other devices.

What should you pay attention to when using automatic save?

Although automatic saving is convenient, you should also pay attention to its behavior in certain specific scenarios:

• If you depend on whether the file has been saved when running scripts or debugging programs, it is recommended to confirm that the automatic save has taken effect.
• When using afterDelay mode, the content may not be saved immediately after writing, and if you run external commands immediately, the latest content may not be read.
• In remote development (Remote - SSH, etc.), automatic save will also write changes to the remote server, which may affect performance.

Overall, this feature is very friendly to most users, and it only needs to be properly set up to greatly improve efficiency.

Basically that's it.
