File action basics

What are file actions?

File actions are the most powerful feature Chonky has to offer. They allow you to tweak file browser behaviour, add custom toolbar buttons, respond to key presses and much more!

To get a sense of how powerful file actions are, consider this - most of the built-in Chonky features, such as file selections & context menu handling, are implemented using file actions. In theory, the definitions for these actions could come from user code, but Chonky provides these features out-of-the-box for convenience.

What can they do?

Using simple file action definitions, you can do the following:

  • Change file sort function.
  • Change current file view.
  • Toggle boolean options.
  • Transform selection.
  • Add buttons to toolbar or context menu.
  • Response to keyboard shortcuts.
  • Trigger the user-defined action handler.

If you dive deeper and make use of file action effects, you can go further:

  • Dispatch other file actions.
  • Prevent user-defined action handler from being triggered.
  • Read and modify Chonky's internal Redux state. This allows you to change Chonky's behaviour in arbitrary ways.

Enabling file actions

You can pass custom file actions to Chonky using the fileActions prop on FileBrowser component:

import { ChonkyActions, defineFileAction, FileBrowser } from 'chonky';
export const MyFileBrowser = () => {
const myCustomAction = defineFileAction({
/* ... */
} as const);
const myFileActions = [
myCustomAction,
ChonkyActions.UploadFiles,
ChonkyActions.DownloadFiles,
];
return (
<FileBrowser files={[]} fileActions={myFileActions}>
{/* ... */}
</FileBrowser>
);
};
