``` ```
## Usage ## Usage
SmartFile is a comprehensive toolkit for file manipulation in Node.js. It provides functionalities for working with the filesystem, in-memory operations, streaming, and handling virtual directories. Below, you will find examples showcasing how to utilize these functionalities effectively. The `@push.rocks/smartfile` library offers a comprehensive suite of tools to work with files in Node.js projects, facilitating a variety of file operations such as reading, writing, streaming, and in-memory manipulation. Below, you'll find detailed examples illustrating how to leverage the library's functionality to tackle real-world tasks.
### Basic File Operations ### Working with Filesystem
For reading and writing files, SmartFile provides synchronous and asynchronous methods. Heres how you can use them: #### Ensuring File and Directory Existence
#### Async Write to File
```typescript ```typescript
import { memory } from '@push.rocks/smartfile'; import { fs } from '@push.rocks/smartfile';
const myData: string = 'Hello, SmartFile!'; // Ensure a file exists with initial content (Async)
await fs.ensureFile('./path/to/new/file.txt', 'Initial content');
// Writing string data to a file asynchronously // Ensure a directory exists (Async)
memory.toFs(myData, './data/hello.txt'); await fs.ensureDir('./path/to/new/dir');
``` ```
#### Sync Write to File #### Getting File Details
```typescript ```typescript
import { memory } from '@push.rocks/smartfile'; import { fs } from '@push.rocks/smartfile';
const myData: string = 'Hello, World!'; // Check if a file exists (Async)
const exists: boolean = await fs.fileExists('./path/to/file.txt');
// Writing string data to a file synchronously // Check if a path is a directory
memory.toFsSync(myData, './data/helloSync.txt'); const isDir: boolean = fs.isDirectory('./path/to/check');
``` ```
### Working with Streams ### Reading and Writing Files
Streaming files to and from the filesystem is made easy with SmartFile. Heres an example: #### Basic Reading and Writing
#### Creating Read and Write Streams
```typescript ```typescript
import { fsStream } from '@push.rocks/smartfile'; import { SmartFile, memory } from '@push.rocks/smartfile';
import * as fs from 'fs';
// Creating a read stream // Read a file to a SmartFile instance (Async)
const readStream = fsStream.createReadStream('./data/readme.txt'); const smartFile: SmartFile = await SmartFile.fromFilePath('./path/to/read/file.txt');
// Creating a write stream // Write SmartFile instance to a new path (Async)
const writeStream = fsStream.createWriteStream('./data/copy.txt'); await smartFile.writeToDir('./path/to/target/dir');
// Piping the read stream to the write stream // Write text content to a file (Async)
readStream.pipe(writeStream); await memory.toFs('Hello SmartFile!', './path/to/output/file.txt');
``` ```
### Dealing with Virtual Directories #### Working with File Contents
Virtual directories allow you to group and manipulate files as if they were in a filesystem structure without actually writing them to disk.
```typescript
import { VirtualDirectory } from '@push.rocks/smartfile';
(async () => {
// Creating a virtual directory from the file system
const virtualDir = await VirtualDirectory.fromFsDirPath('./myDirectory');
// Adding files from another virtual directory
const anotherVirtualDir = await VirtualDirectory.fromFsDirPath('./anotherDirectory');
await virtualDir.addVirtualDirectory(anotherVirtualDir, 'merged');
// Saving the virtual directory to disk
await virtualDir.saveToDisk('./outputDirectory');
})();
```
### Advanced File Manipulation
SmartFile also allows for more advanced file manipulation techniques through the `SmartFile` class.
```typescript ```typescript
import { SmartFile } from '@push.rocks/smartfile'; import { SmartFile } from '@push.rocks/smartfile';
(async () => { // Creating SmartFile instance from text
// Create a SmartFile instance from a file path const smartFileFromText: SmartFile = await SmartFile.fromString('./path/to/text/file.txt', 'Text content here', 'utf8');
const smartFile = await SmartFile.fromFilePath('./data/example.txt');
// Edit the file content // Reading content from SmartFile instance
await smartFile.editContentAsString(async (currentContent: string) => { const content: string = smartFileFromText.contents.toString();
return currentContent.toUpperCase();
});
// Write the changes back to disk // Editing content of SmartFile
await smartFile.write(); await smartFileFromText.editContentAsString(async (currentContent: string) => `Modified: ${currentContent}`);
})();
``` ```
### Conversion and Interpretation ### File Streaming
You can easily convert file contents to objects or interpret file types for further processing:
```typescript ```typescript
import { memory } from '@push.rocks/smartfile'; import { StreamFile } from '@push.rocks/smartfile';
(async () => { // Creating a StreamFile from a file path (Async)
const fileString: string = await fs.promises.readFile('./data/example.json', 'utf8'); const streamFile: StreamFile = await StreamFile.fromPath('./path/to/large/file.avi');
const fileObject = memory.toObject(fileString, 'json');
console.log(fileObject); // Streaming file content to disk (Async)
// Proceed with the object... await streamFile.writeToDisk('./path/to/target/file.avi');
})();
``` ```
SmartFile simplifies handling files in a Node.js environment, providing a concise, promise-based API for various file operations, stream handling, and in-memory file manipulation. Whether you're dealing with physical files on the disk, manipulating file streams, or managing virtual files and directories, SmartFile has got you covered. #### Utilizing Stream Files from URLs
## Information on Licensing ```typescript
import { StreamFile } from '@push.rocks/smartfile';
SmartFile is licensed under the MIT License. This permissive license is short and to the point. It lets people do anything they want with your code as long as they provide attribution back to you and dont hold you liable. // Creating a StreamFile from URL (Async)
const streamFileFromURL: StreamFile = await StreamFile.fromUrl('https://example.com/data.json');
// Accessing StreamFile content as string (Async, for textual data)
const contentAsString: string = await streamFileFromURL.getContentAsString();
```
### Handling Virtual Directories
```typescript
import { VirtualDirectory, SmartFile } from '@push.rocks/smartfile';
// Creating a virtual directory from existing directory on disk (Async)
const virtualDirectory: VirtualDirectory = await VirtualDirectory.fromFsDirPath('./path/to/source/dir');
// Adding files to virtual directory
virtualDirectory.addSmartfiles([await SmartFile.fromFilePath('./path/to/extra/file.txt')]);
// Saving virtual directory to disk (Async)
await virtualDirectory.saveToDisk('./path/to/destination/dir');
```
#### Manipulating File Paths
```typescript
import { SmartFile } from '@push.rocks/smartfile';
// Read SmartFile and change its relative path
const smartFile: SmartFile = await SmartFile.fromFilePath('./path/to/original/file.txt');
smartFile.updateFileName('newFilename.txt'); // Retains original directory but changes file name
```
### Security and Hashing
```typescript
import { SmartFile } from '@push.rocks/smartfile';
// Creating SmartFile instance and getting hash
const smartFileForHash: SmartFile = await SmartFile.fromString('./fileForHashing.txt', 'Content for hashing', 'utf8');
const hash: string = await smartFileForHash.getHash('content'); // 'content', 'path', or 'all'
```
### Advanced Streaming via `SmartReadStream`
For handling edge cases such as streaming large files that are being written concurrently (e.g., log files), `SmartReadStream` can be employed to monitor files for new data and stream content as it becomes available.
```typescript
import { fsStream } from '@push.rocks/smartfile';
const smartReadStream = new fsStream.SmartReadStream('./path/to/live/file.log');
smartReadStream
.on('data', (chunk) => {
// Process streamed data
})
.on('error', (err) => {
console.error('Stream encountered an error:', err);
})
.on('end', () => {
console.log('No more data available.');
});
```
In conclusion, `@push.rocks/smartfile` equips developers with a highly versatile API for file manipulation, enhancing productivity in handling file operations within Node.js applications. By leveraging the examples provided, users can efficiently integrate file processing tasks into their projects, streamlining workflows and achieving granular control over file and directory management.
