# FileSystem Package Gap Analysis
## Overview
This document analyzes the gaps between our current filesystem handling (in Core package) and Laravel's FileSystem package functionality, identifying what needs to be implemented as a standalone FileSystem package.
> **Related Documentation**
> - See [FileSystem Package Specification](filesystem_package_specification.md) for current implementation
> - See [Laravel Compatibility Roadmap](laravel_compatibility_roadmap.md) for overall status
> - See [Foundation Integration Guide](foundation_integration_guide.md) for integration patterns
> - See [Testing Guide](testing_guide.md) for testing approaches
> - See [Getting Started Guide](getting_started.md) for development setup
## Implementation Gaps
### 1. Missing Package Structure
```dart
// Need to create dedicated FileSystem package:
packages/filesystem/
├── lib/
├── src/
├── filesystem.dart
├── filesystem_manager.dart
├── drivers/
├── local_driver.dart
├── s3_driver.dart
└── gcs_driver.dart
└── contracts/
├── filesystem.dart
└── driver.dart
└── filesystem.dart
├── test/
└── example/
```
### 2. Missing Core Features
```dart
// 1. Filesystem Manager
class FilesystemManager {
// Need to implement:
Filesystem disk([String? name]);
void extend(String driver, FilesystemDriver Function() callback);
FilesystemDriver createDriver(Map<String, dynamic> config);
}
// 2. Filesystem Implementation
class Filesystem {
// Need to implement:
Future<bool> exists(String path);
Future<String> get(String path);
Future<void> put(String path, dynamic contents, [Map<String, String>? options]);
Future<void> delete(String path);
Future<void> copy(String from, String to);
Future<void> move(String from, String to);
Future<String> url(String path);
Future<Stream<List<int>>> readStream(String path);
Future<void> writeStream(String path, Stream<List<int>> contents);
}
// 3. Driver Implementations
class LocalDriver {
// Need to implement:
Future<void> ensureDirectory(String path);
Future<void> setVisibility(String path, String visibility);
Future<Map<String, dynamic>> getMetadata(String path);
}
```
### 3. Missing Laravel Features
```dart
// 1. Cloud Storage
class S3Driver {
// Need to implement:
Future<void> upload(String path, dynamic contents, String visibility);
Future<String> temporaryUrl(String path, Duration expiration);
Future<void> setVisibility(String path, String visibility);
}
// 2. Directory Operations
class DirectoryOperations {
// Need to implement:
Future<List<String>> files(String directory);
Future<List<String>> allFiles(String directory);
Future<List<String>> directories(String directory);
Future<List<String>> allDirectories(String directory);
Future<void> makeDirectory(String path);
Future<void> deleteDirectory(String directory);
}
// 3. File Visibility
class VisibilityConverter {
// Need to implement:
String toOctal(String visibility);
String fromOctal(String permissions);
bool isPublic(String path);
bool isPrivate(String path);
}
```
## Integration Gaps
### 1. Container Integration
```dart
// Need to implement:
class FilesystemServiceProvider {
void register() {
// Register filesystem manager
container.singleton<FilesystemManager>((c) =>
FilesystemManager(
config: c.make<ConfigContract>()
)
);
// Register default filesystem
container.singleton<Filesystem>((c) =>
c.make<FilesystemManager>().disk()
);
}
}
```
### 2. Config Integration
```dart
// Need to implement:
// config/filesystems.dart
class FilesystemsConfig {
static Map<String, dynamic> get config => {
'default': 'local',
'disks': {
'local': {
'driver': 'local',
'root': 'storage/app'
},
's3': {
'driver': 's3',
'key': env('AWS_ACCESS_KEY_ID'),
'secret': env('AWS_SECRET_ACCESS_KEY'),
'region': env('AWS_DEFAULT_REGION'),
'bucket': env('AWS_BUCKET')
}
}
};
}
```
### 3. Event Integration
```dart
// Need to implement:
class FilesystemEvents {
// File events
static const String writing = 'filesystem.writing';
static const String written = 'filesystem.written';
static const String deleting = 'filesystem.deleting';
static const String deleted = 'filesystem.deleted';
// Directory events
static const String makingDirectory = 'filesystem.making_directory';
static const String madeDirectory = 'filesystem.made_directory';
static const String deletingDirectory = 'filesystem.deleting_directory';
static const String deletedDirectory = 'filesystem.deleted_directory';
}
```
## Documentation Gaps
### 1. Missing API Documentation
```dart
// Need to document:
/// Manages filesystem operations across multiple storage drivers.
///
/// Provides a unified API for working with files across different storage systems:
/// ```dart
/// // Store a file
/// await storage.put('avatars/user1.jpg', fileContents);
///
/// // Get a file
/// var contents = await storage.get('avatars/user1.jpg');
/// ```
class Filesystem {
/// Stores a file at the specified path.
///
/// Options can include:
/// - visibility: 'public' or 'private'
/// - mime: MIME type of the file
Future<void> put(String path, dynamic contents, [Map<String, String>? options]);
}
```
### 2. Missing Usage Examples
```dart
// Need examples for:
// 1. Basic File Operations
var storage = Storage.disk();
await storage.put('file.txt', 'Hello World');
var contents = await storage.get('file.txt');
await storage.delete('file.txt');
// 2. Stream Operations
var fileStream = File('large.zip').openRead();
await storage.writeStream('uploads/large.zip', fileStream);
var downloadStream = await storage.readStream('uploads/large.zip');
// 3. Cloud Storage
var s3 = Storage.disk('s3');
await s3.put(
'images/photo.jpg',
photoBytes,
{'visibility': 'public'}
);
var url = await s3.url('images/photo.jpg');
```
### 3. Missing Test Coverage
```dart
// Need tests for:
void main() {
group('Local Driver', () {
test('handles file operations', () async {
var storage = Filesystem(LocalDriver(root: 'storage'));
await storage.put('test.txt', 'contents');
expect(await storage.exists('test.txt'), isTrue);
expect(await storage.get('test.txt'), equals('contents'));
await storage.delete('test.txt');
expect(await storage.exists('test.txt'), isFalse);
});
});
group('S3 Driver', () {
test('handles cloud operations', () async {
var storage = Filesystem(S3Driver(config));
await storage.put('test.txt', 'contents', {
'visibility': 'public'
});
var url = await storage.url('test.txt');
expect(url, startsWith('https://'));
});
});
}
```

### 2. Implementation Process
For each filesystem feature:

### 4. Integration Considerations
When implementing filesystem features:
1. Follow patterns in [Foundation Integration Guide](foundation_integration_guide.md)

5. Meet performance targets in [Laravel Compatibility Roadmap](laravel_compatibility_roadmap.md#performance-benchmarks)
### 6. Testing Requirements
Filesystem tests must:
1. Cover all file operations
2. Test streaming behavior
3. Verify cloud storage
4. Check metadata handling
5. Follow patterns in [Testing Guide](testing_guide.md)
### 7. Documentation Requirements
