Save and revert changes
JetBrains Rider automatically saves changes that you make in your files. Saving is triggered by various events, such as compiling, running, debugging, performing version control operations, closing a file or a project, or quitting the IDE. Saving files can be also triggered by third-party plugins.
Most of the events that trigger auto-save are predefined and cannot be configured, but you can be sure that changes will not be lost and you can find all of them in local history.
Configure autosave behavior
In the Settings/Preferences dialog (Ctrl+Alt+S) , select .
Under Sync external changes, configure the following options:
Save files when switching to a different application or a built-in terminal: Save all modified files when you switch from JetBrains Rider to a different application.
Save files if the IDE is idle for N seconds: Save all modified files at regular time intervals.
Apply the changes and close the dialog.
Mark files with unsaved changes
You can mark unsaved files with an asterisk (*) on the file tab:
In the Settings/Preferences dialog (Ctrl+Alt+S) , select .
Select the Mark modified (*) checkbox.
Apply the changes and close the dialog.
After that, the tab of the file in which you have unsaved changes will be marked with an asterisk.
If you use version control integration, names of all modified files will be also marked with a dedicated color on the file tab and in the Project tool window.
Save changes manually
You can always save your changes manually:
Press Ctrl+S or select from the main menu.
Trigger actions when saving changes
In JetBrains Rider, you can configure the actions that will be triggered every time your modified files are saved.
To configure autosave actions for the current project, in the Settings/Preferences dialog (Ctrl+Alt+S) , open .
To configure the actions for new projects, go to in the main menu.
Select the checkboxes next to the actions that you want to trigger on save:
Reformat and Cleanup Code: run cleanup tasks from the selected code cleanup profile, which can include such tasks as reformatting code, removing code redundancies, and so on.
Run eslint --fix: fix the detected problems with ESlint.
Enabling this option also enables Run eslint --fix on save.
File Watcher: run your configured file watchers.
Upload to default server: upload modified files to your default deployment server.
Enabling this option also enables Upload changed files automatically to the default server.
For some actions, you can configure the settings more precisely. To do so, hover over an action and click the configuration link.
Apply the changes and close the dialog.
Once the necessary actions are enabled, they will be automatically triggered on every save (autosave, explicit save invoked with Ctrl+S or by selecting ) as you work with your project.
Revert changes
For most recent changes, including refactorings, press Ctrl+Z or choose from the menu.
For a more detailed view of past changes, use Local History.
For the most robust tracking of all changes, use a version control system.
