### Register FilePond Plugins

Source: https://context7.com/pqina/react-filepond/llms.txt

Shows how to register FilePond plugins to extend functionality, such as image preview and EXIF orientation correction. Ensure plugins are installed and imported before registration.

```jsx
import { FilePond, registerPlugin } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

// Install plugins: npm i filepond-plugin-image-preview filepond-plugin-image-exif-orientation --save
import FilePondPluginImageExifOrientation from 'filepond-plugin-image-exif-orientation';
import FilePondPluginImagePreview from 'filepond-plugin-image-preview';
import 'filepond-plugin-image-preview/dist/filepond-plugin-image-preview.css';

// Register plugins before using FilePond component
registerPlugin(FilePondPluginImageExifOrientation, FilePondPluginImagePreview);

function App() {
  const [files, setFiles] = useState([]);
  return (
    <FilePond
      files={files}
      onupdatefiles={setFiles}
      allowMultiple={true}
    />
  );
}

```

--------------------------------

### React FilePond with Hooks

Source: https://github.com/pqina/react-filepond/blob/master/README.md

Example of using FilePond in a React functional component with hooks. It demonstrates state management for files and plugin registration for image preview and EXIF orientation.

```jsx
import React, { useState } from 'react'
import ReactDOM from 'react-dom'

// Import React FilePond
import { FilePond, registerPlugin } from 'react-filepond'

// Import FilePond styles
import 'filepond/dist/filepond.min.css'

// Import the Image EXIF Orientation and Image Preview plugins
// Note: These need to be installed separately
// `npm i filepond-plugin-image-preview filepond-plugin-image-exif-orientation --save`
import FilePondPluginImageExifOrientation from 'filepond-plugin-image-exif-orientation'
import FilePondPluginImagePreview from 'filepond-plugin-image-preview'
import 'filepond-plugin-image-preview/dist/filepond-plugin-image-preview.css'

// Register the plugins
registerPlugin(FilePondPluginImageExifOrientation, FilePondPluginImagePreview)

// Our app
function App() {
  const [files, setFiles] = useState([])
  return (
    <div className="App">
      <FilePond
        files={files}
        onupdatefiles={setFiles}
        allowMultiple={true}
        maxFiles={3}
        server="/api"
        name="files" /* sets the file input name, it's filepond by default */
        labelIdle='Drag & Drop your files or <span class="filepond--label-action">Browse</span>'
      />
    </div>
  )
}
```

--------------------------------

### Enable Drag and Drop with Reordering

Source: https://context7.com/pqina/react-filepond/llms.txt

Allow users to reorder files before uploading by setting the `allowReorder` prop to `true`. This example also includes a `labelIdle` prop for custom drag-and-drop instructions.

```jsx
import React, { useState } from 'react';
import { FilePond } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

function ReorderableUploader() {
  const [files, setFiles] = useState([]);

  return (
    <FilePond
      files={files}
      onupdatefiles={setFiles}
      allowMultiple={true}
      allowReorder={true}
      maxFiles={10}
      server="/api/upload"
      onreorderfiles={(files) => {
        console.log('Files reordered:', files.map(f => f.filename));
      }}
      labelIdle='Drag & Drop files or <span class="filepond--label-action">Browse</span><br/>Drag to reorder'
    />
  );
}
```

--------------------------------

### React FilePond with Class Component

Source: https://github.com/pqina/react-filepond/blob/master/README.md

Example of using FilePond in a React class component. This includes initializing with existing files, handling instance initialization, and updating state with uploaded files. Plugins for image preview and EXIF orientation are also registered.

```jsx
import React, { useState } from 'react'
import ReactDOM from 'react-dom'

// Import React FilePond
import { FilePond, registerPlugin } from "react-filepond";

// Import FilePond styles
import "filepond/dist/filepond.min.css";

// Import the Image EXIF Orientation and Image Preview plugins
// Note: These need to be installed separately
import FilePondPluginImageExifOrientation from "filepond-plugin-image-exif-orientation";
import FilePondPluginImagePreview from "filepond-plugin-image-preview";
import "filepond-plugin-image-preview/dist/filepond-plugin-image-preview.css";

// Register the plugins
registerPlugin(FilePondPluginImageExifOrientation, FilePondPluginImagePreview);

// Our app
class App extends Component {
  constructor(props) {
    super(props);

    this.state = {
      // Set initial files, type 'local' means this is a file
      // that has already been uploaded to the server (see docs)
      files: [
        {
          source: "index.html",
          options: {
            type: "local"
          }
        }
      ]
    };
  }

  handleInit() {
    console.log("FilePond instance has initialised", this.pond);
  }

  render() {
    return (
      <div className="App">
        <FilePond
          ref={ref => (this.pond = ref)}
          files={this.state.files}
          allowMultiple={true}
          allowReorder={true}
          maxFiles={3}
          server="/api"
          name="files" /* sets the file input name, it's filepond by default */
          oninit={() => this.handleInit()}
          onupdatefiles={fileItems => {
            // Set currently active file objects to this.state
            this.setState({
              files: fileItems.map(fileItem => fileItem.file)
            });
          }}
        />
      </div>
    );
  }
}

```

--------------------------------

### Basic FilePond Component Usage

Source: https://context7.com/pqina/react-filepond/llms.txt

Demonstrates the basic setup of the FilePond component in a React application. It allows multiple file uploads with a maximum of 3 files and configures the server endpoint for uploads.

```jsx
import React, { useState } from 'react';
import { FilePond, registerPlugin } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

function FileUploader() {
  const [files, setFiles] = useState([]);

  return (
    <FilePond
      files={files}
      onupdatefiles={setFiles}
      allowMultiple={true}
      maxFiles={3}
      server="/api/upload"
      name="files"
      labelIdle='Drag & Drop your files or <span class="filepond--label-action">Browse</span>'
    />
  );
}

```

--------------------------------

### Advanced Server Configuration for File Uploads

Source: https://context7.com/pqina/react-filepond/llms.txt

Configures custom server handlers for processing, loading, reverting, and restoring files. This example uses XMLHttpRequest for processing uploads and fetch API for load and revert operations.

```jsx
import React, { useState } from 'react';
import { FilePond } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

function AdvancedUploader() {
  const [files, setFiles] = useState([]);

  return (
    <FilePond
      files={files}
      onupdatefiles={setFiles}
      allowMultiple={true}
      server={{
        process: (fieldName, file, metadata, load, error, progress, abort) => {
          const formData = new FormData();
          formData.append(fieldName, file, file.name);

          const request = new XMLHttpRequest();
          request.open('POST', '/api/upload');

          request.upload.onprogress = (e) => {
            progress(e.lengthComputable, e.loaded, e.total);
          };

          request.onload = function() {
            if (request.status >= 200 && request.status < 300) {
              load(request.responseText); // Server returns unique file ID
            } else {
              error('Upload failed');
            }
          };

          request.send(formData);

          return {
            abort: () => {
              request.abort();
              abort();
            }
          };
        },
        load: (source, load, error, progress, abort) => {
          fetch(source)
            .then(res => res.blob())
            .then(load)
            .catch(error);
        },
        revert: (uniqueFileId, load, error) => {
          fetch(`/api/upload/${uniqueFileId}`, { method: 'DELETE' })
            .then(load)
            .catch(error);
        }
      }}
    />
  );
}

```

--------------------------------

### Track File Upload States with FileStatus

Source: https://context7.com/pqina/react-filepond/llms.txt

Use the FileStatus constants to monitor and react to different stages of the file upload process, such as processing completion or errors. This example demonstrates updating a status message based on upload outcomes.

```jsx
import React, { useState } from 'react';
import { FilePond, FileStatus } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

function StatusAwareUploader() {
  const [files, setFiles] = useState([]);
  const [statusMessage, setStatusMessage] = useState('');

  const handleProcessFile = (error, file) => {
    if (file.status === FileStatus.PROCESSING_COMPLETE) {
      setStatusMessage(`${file.filename} uploaded successfully!`);
    } else if (file.status === FileStatus.PROCESSING_ERROR) {
      setStatusMessage(`${file.filename} failed to upload.`);
    }
  };

  return (
    <div>
      <FilePond
        files={files}
        onupdatefiles={setFiles}
        allowMultiple={true}
        server="/api/upload"
        onprocessfile={handleProcessFile}
      />
      <p>{statusMessage}</p>
    </div>
  );
}
```

--------------------------------

### Pre-populating Files in React FilePond

Source: https://context7.com/pqina/react-filepond/llms.txt

Use the `files` prop to set initial files. Specify local server files using `source` and `options.type`, or remote files from URLs.

```jsx
import React, { Component } from 'react';
import { FilePond, registerPlugin } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

class FileManager extends Component {
  constructor(props) {
    super(props);
    this.state = {
      files: [
        {
          source: 'photo.jpeg',
          options: {
            type: 'local' // File already on server
          }
        },
        {
          source: 'https://example.com/remote-file.pdf',
          options: {
            type: 'remote' // File from remote URL
          }
        }
      ]
    };
  }

  render() {
    return (
      <FilePond
        files={this.state.files}
        allowMultiple={true}
        server={{
          load: (source, load) => {
            fetch(source)
              .then(res => res.blob())
              .then(load);
          }
        }}
        onupdatefiles={fileItems => {
          this.setState({
            files: fileItems.map(fileItem => fileItem.file)
          });
        }}
      />
    );
  }
}
```

--------------------------------

### Configure File Validation and Restrictions

Source: https://context7.com/pqina/react-filepond/llms.txt

Implement file type, size, and quantity restrictions using props like `acceptedFileTypes`, `maxFileSize`, and `maxFiles`. Ensure necessary plugins are registered before use.

```jsx
import React, { useState } from 'react';
import { FilePond, registerPlugin } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

// npm i filepond-plugin-file-validate-type filepond-plugin-file-validate-size --save
import FilePondPluginFileValidateType from 'filepond-plugin-file-validate-type';
import FilePondPluginFileValidateSize from 'filepond-plugin-file-validate-size';

registerPlugin(FilePondPluginFileValidateType, FilePondPluginFileValidateSize);

function RestrictedUploader() {
  const [files, setFiles] = useState([]);

  return (
    <FilePond
      files={files}
      onupdatefiles={setFiles}
      allowMultiple={true}
      maxFiles={5}
      maxFileSize="5MB"
      acceptedFileTypes={['image/png', 'image/jpeg', 'application/pdf']}
      server="/api/upload"
      labelMaxFileSizeExceeded="File is too large"
      labelMaxFileSize="Maximum file size is {filesize}"
      labelFileTypeNotAllowed="Invalid file type"
      fileValidateTypeLabelExpectedTypes="Expects {allButLastType} or {lastType}"
    />
  );
}
```

--------------------------------

### Handling FilePond Event Callbacks in React

Source: https://context7.com/pqina/react-filepond/llms.txt

Implement event callbacks for file lifecycle events such as init, add, remove, process, and error handling to manage file operations and user feedback.

```jsx
import React, { useState } from 'react';
import { FilePond } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

function FileUploaderWithEvents() {
  const [files, setFiles] = useState([]);

  return (
    <FilePond
      files={files}
      onupdatefiles={setFiles}
      allowMultiple={true}
      server="/api/upload"
      oninit={() => {
        console.log('FilePond initialized');
      }}
      onaddfile={(error, file) => {
        if (error) {
          console.error('Error adding file:', error);
          return;
        }
        console.log('File added:', file.filename);
      }}
      onremovefile={(error, file) => {
        if (error) {
          console.error('Error removing file:', error);
          return;
        }
        console.log('File removed:', file.filename);
      }}
      onprocessfile={(error, file) => {
        if (error) {
          console.error('Error processing file:', error);
          return;
        }
        console.log('File processed:', file.filename, 'Server ID:', file.serverId);
      }}
      onprocessfiles={() => {
        console.log('All files processed');
      }}
      onerror={(error, file, status) => {
        console.error('FilePond error:', error, file, status);
      }}
    />
  );
}
```

--------------------------------

### Accessing FilePond Instance Methods in React

Source: https://context7.com/pqina/react-filepond/llms.txt

Utilize a React ref to access FilePond instance methods like `addFile()`, `removeFile()`, `processFile()`, and `getFiles()` for programmatic control.

```jsx
import React, { Component } from 'react';
import { FilePond } from 'react-filepond';
import 'filepond/dist/filepond.min.css';

class ControlledUploader extends Component {
  constructor(props) {
    super(props);
    this.state = { files: [] };
  }

  handleInit() {
    console.log('FilePond instance has initialised', this.pond);
  }

  addFileFromUrl() {
    this.pond.addFile('https://example.com/image.jpg');
  }

  clearAllFiles() {
    this.pond.removeFiles();
  }

  processAllFiles() {
    this.pond.processFiles();
  }

  render() {
    return (
      <div>
        <FilePond
          ref={ref => (this.pond = ref)}
          files={this.state.files}
          allowMultiple={true}
          server="/api/upload"
          oninit={() => this.handleInit()}
          onupdatefiles={fileItems => {
            this.setState({
              files: fileItems.map(fileItem => fileItem.file)
            });
          }}
        />
        <button onClick={() => this.addFileFromUrl()}>Add File from URL</button>
        <button onClick={() => this.clearAllFiles()}>Clear All</button>
        <button onClick={() => this.processAllFiles()}>Upload All</button>
      </div>
    );
  }
}
```
