React File Manager

An open-source React package for easy integration of a file manager into applications. It provides a user-friendly interface for managing files and folders, including viewing, uploading, and deleting, with full UI and backend integration.

This project is forked from this fantastic project.

And our source code project is here.

✨ Features

• File & Folder Management: View, upload, download, delete, copy, move, create, and rename files or folders seamlessly.
• Grid & List View: Switch between grid and list views to browse files in your preferred layout.
• Search: the navigation pane includes a search feature for filtering files on current directory.
• Status bar: RFM has an optional status bar where info about current folder and current selection items is shown.
• View options: The file manager includes view options like classical desktop file managers.
• Navigation: Use the breadcrumb trail and sidebar navigation pane for quick directory traversal.
• Toolbar & Context Menu: Access all common actions (upload, download, delete, copy, move, rename, etc.) via the toolbar or right-click for the same options in the context menu.
• Context cutomization: Add your specific icons and actions for your unique object types. They will be shown when needed and added to context menus.
• Multi-Selection: Select multiple files and folders at once to perform bulk actions like delete, copy, move, or download.
• Keyboard Shortcuts: Quickly perform file operations like copy, paste, delete, and more using intuitive keyboard shortcuts.
• Drag-and-Drop: Move selected files and folders by dragging them to the desired directory, making file organization effortless.

🚀 Installation

To install React File Manager, use the following command:

npm i @jfvilas/react-file-manager

💻 Usage

Here’s a basic example of how to use the File Manager Component in your React application:

import { useState } from "react";
import { FileManager } from "@jfvilas/react-file-manager";
import "@jfvilas/react-file-manager/dist/style.css";

function App() {
  const [files, setFiles] = useState([
    {
      name: "Documents",
      isDirectory: true, // Folder
      path: "/Documents", // Located in Root directory
      updatedAt: "2024-09-09T10:30:00Z", // Last updated time
    },
    {
      name: "Pictures",
      isDirectory: true,
      path: "/Pictures", // Located in Root directory as well
      updatedAt: "2024-09-09T11:00:00Z",
    },
    {
      name: "Pic.png",
      isDirectory: false, // File
      path: "/Pictures/Pic.png", // Located inside the "Pictures" folder
      updatedAt: "2024-09-08T16:45:00Z",
      size: 2048, // File size in bytes (example: 2 KB)
      class: 'image' // optional property for customization
    },
  ]);

  return (
    <>
      <FileManager files={files} />
    </>
  );
}

export default App;

Typescript Usage

If you plan to user react-file-manager in a Typescript project, you can add type management by adding a .d.ts file. What follows is a sample file, but you can download a full module declaration file here. Inside that file you will find a module declaration and a bunch of type and interface declarations. What follows is just a excerpt.

declare module '@jfvilas/react-file-manager' {
    export interface IFileData {
        name: string;
        isDirectory: boolean;
        path: string;
        updatedAt?: string;
        size?: number;
        class?: string;
    }

    export interface IError {
        type: string,
        message: string,
        response: {
            status: number,
            statusText: string,
            data: any,
        }
    }
...

In order to use this 'types' declaration file, just download and add it to your project inside your source folder (or any other folder and change your package.json accordingly).

📂 File Structure

The files prop accepts an array of objects, where each object represents a file or folder. You can customize the structure to meet your application needs. Each file or folder object follows the structure detailed below:

type File = {
  name: string;
  isDirectory: boolean;
  path: string;
  updatedAt?: string; // Optional: Last update timestamp in ISO 8601 format
  size?: number; // Optional: File size in bytes (only applicable for files)
  class?:string; // Optional: File class to be used with custom icons and custom actions
};

🎬 Icons & Actions

By adding your own icons and specific actions for your items, you can think of react-file-manager as just a hierarchical object manager, that is, this package is no longer just a file manager, you can, for example, create a hierarchy of books and implement particular actions. For example...:

• You can have a top level category that consists of types of books: novel, essay, history...
• On a second level you can add the topic: science-fiction, love, thriller...
• On a third level you can just store the book title and metadata.

You can also add specific icons for each object (category, topic, book).

Moreover, you can add specific actions for each type of object:

• For the top level, a sample action could be to show the list of books that belong to that category.
• For the third level, the book in itself, you could add some actions like: read, view details, share link...

You can build interfaces like this (this one has been built for a kubernetes file navigator):

For achieving these objectives you need to add to each entry in the files object an optional property called class. So, for the top level, the class property could be category. For the second level, the value of class could be something like topic, and for the third level it could be something like book.

The next step is to add the icons for these objects. You must create a Map like this one:

  let icons = new Map();
  icons.set('category', { open: <JSX.Element />, closed: <JSX.Element />, list: <JSX.Element />, grid: <JSX.Element /> })
  icons.set('topic', { default: <JSX.Element /> })
  icons.set('book', { open: <JSX.Element />, closed: <JSX.Element /> })

This way, when rendering an object with the class category, react-file-manager will show the proper icon, in the folder tree and also in the file list, wherever it be a grid or a list layout.

If you want to add specific actions for each class, you must create an actions map like this:

  let actions = new Map();
  actions.set('book', [
    {
      title: 'Read book',
      icon: <FaRead />,
      onClick: (files) => {
        console.log('onclick view:', files)
      }
    },
    {
      title: 'Book details',
      icon: <FaBook />,
      onClick: (files) => {
        console.log('onclick delete:', files)
      }
    }
  ])

The previous piece of code adds two actions to objects of class book:

• One for reading the book (the onClick method should open an ebook reader on screen).
• Another one for viewing book details.

A typical action contains these properties (review the .d.td file):

• title: the text to appear in context menus.
• icon: the icon to show next to the text.
• onClick: a function to process the action (one only parameter will be send: an array contianing the files which the action must be executed on).

Once you have defined your icons and your actions, you just need to add them to your FileManager object like this:

  <FileManager files={files} icons={icons} actions={actions} />

...And you'll see the magic 🪄!!

What follows is an example with Kubernetes objects, icons and actions that we have implemented in Kwirth project.

🎨 UI Customization

react-file-manager can be easily customized to meet your React application UI styles.

The simplest way for customizing this component is as follows:

1. Create a .css file in your project directory (custom-fm.css, for example).
2. Import it in the JSX or TSX file that contains your FileManager object:

import './custom-fm.css'

3. Customize your FileManager by adding classes to the custom-fm.css file. For example (please note we add our class name custom-fm on each style):

.custom-fm .toolbar {
  background-color: #e0e0e0;
  border-top-left-radius: 8px;
  border-top-right-radius: 8px;
}

.custom-fm .files-container {
  background-color: #f0f0f0;
}

4. Add your class name to your FileManager object this way:

<FileManager ... className='custom-fm'>

Et voilà !

🛡️ Permissions

Control file management actions using the permissions prop (optional). Actions default to true if not specified.

<FileManager
  // Other props...
  permissions={{
    create: false, // Disable "Create Folder"
    delete: false, // Disable "Delete"
    download: true, // Enable "Download"
    copy: true,
    move: true,
    rename: true,
    upload: true,
  }}
/>

</> Custom File Preview

The FileManager component allows you to provide a custom file preview by passing the filePreviewComponent prop. This is an optional callback function that receives the selected file as an argument and must return a valid React node, JSX element, or HTML.

Usage Example

const CustomImagePreviewer = ({ file }) => {
  return <img src={`${file.path}`} alt={file.name} />;
};

<FileManager
  // Other props...
  filePreviewComponent={(file) => <CustomImagePreviewer file={file} />}
/>;

🧭 Handling Current Path

By default, the file manager starts in the root directory (""). You can override this by passing an initialPath prop. For example, to start in /Documents:

<FileManager initialPath="/Documents" />

Controlled usage with currentPath

If you want to track and control the current folder, you can pair initialPath with the onFolderChange callback. A common pattern is to keep the path in React state:

import { useState } from "react";

function App() {
  const [currentPath, setCurrentPath] = useState("/Documents");

  return (
    <FileManager
      // other props...
      initialPath={currentPath}
      onFolderChange={setCurrentPath}
    />
  );
}
