|
||||
|
||||
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.
|
||||
`@push.rocks/smartfile` offers extensive file management utilities, enabling seamless file processing with TypeScript in a Node.js environment. Below are detailed examples showcasing various features of the module.
|
||||
|
||||
### Working with Filesystem
|
||||
### Quick Start
|
||||
|
||||
#### Ensuring File and Directory Existence
|
||||
First, ensure you're working in an environment that supports ECMAScript modules (ESM) and TypeScript. Here’s how you’d generally import and use `@push.rocks/smartfile`:
|
||||
|
||||
```typescript
|
||||
import { fs } from '@push.rocks/smartfile';
|
||||
|
||||
// Ensure a file exists with initial content (Async)
|
||||
await fs.ensureFile('./path/to/new/file.txt', 'Initial content');
|
||||
|
||||
// Ensure a directory exists (Async)
|
||||
await fs.ensureDir('./path/to/new/dir');
|
||||
import { SmartFile, StreamFile, VirtualDirectory, fs, memory } from '@push.rocks/smartfile';
|
||||
```
|
||||
|
||||
#### Getting File Details
|
||||
### Working with `SmartFile`
|
||||
|
||||
#### Reading Files
|
||||
|
||||
To read from a file and convert it to a `SmartFile` instance:
|
||||
|
||||
```typescript
|
||||
import { fs } from '@push.rocks/smartfile';
|
||||
|
||||
// Check if a file exists (Async)
|
||||
const exists: boolean = await fs.fileExists('./path/to/file.txt');
|
||||
|
||||
// Check if a path is a directory
|
||||
const isDir: boolean = fs.isDirectory('./path/to/check');
|
||||
const myJsonSmartFile: SmartFile = await SmartFile.fromFilePath('./somePath/data.json');
|
||||
const jsonData = JSON.parse(myJsonSmartFile.contents.toString());
|
||||
console.log(jsonData); // Assuming the file contains JSON content
|
||||
```
|
||||
|
||||
### Reading and Writing Files
|
||||
#### Writing Files
|
||||
|
||||
#### Basic Reading and Writing
|
||||
To write data to a file through a `SmartFile`:
|
||||
|
||||
```typescript
|
||||
import { SmartFile, memory } from '@push.rocks/smartfile';
|
||||
|
||||
// Read a file to a SmartFile instance (Async)
|
||||
const smartFile: SmartFile = await SmartFile.fromFilePath('./path/to/read/file.txt');
|
||||
|
||||
// Write SmartFile instance to a new path (Async)
|
||||
await smartFile.writeToDir('./path/to/target/dir');
|
||||
|
||||
// Write text content to a file (Async)
|
||||
await memory.toFs('Hello SmartFile!', './path/to/output/file.txt');
|
||||
const filePath: string = './output/outputData.json';
|
||||
const content: string = JSON.stringify({ key: 'value' });
|
||||
await memory.toFs(content, filePath);
|
||||
```
|
||||
|
||||
#### Working with File Contents
|
||||
### Streaming Large Files with `StreamFile`
|
||||
|
||||
When dealing with large files, you can use `StreamFile` to handle such files efficiently, minimizing memory usage:
|
||||
|
||||
```typescript
|
||||
import { SmartFile } from '@push.rocks/smartfile';
|
||||
|
||||
// Creating SmartFile instance from text
|
||||
const smartFileFromText: SmartFile = await SmartFile.fromString('./path/to/text/file.txt', 'Text content here', 'utf8');
|
||||
|
||||
// Reading content from SmartFile instance
|
||||
const content: string = smartFileFromText.contents.toString();
|
||||
|
||||
// Editing content of SmartFile
|
||||
await smartFileFromText.editContentAsString(async (currentContent: string) => `Modified: ${currentContent}`);
|
||||
const largeFile: StreamFile = await StreamFile.fromPath('./largeInput/largeFile.mp4');
|
||||
await largeFile.writeToDisk('./largeOutput/largeFileCopy.mp4');
|
||||
```
|
||||
|
||||
### File Streaming
|
||||
### Managing Virtual Directories
|
||||
|
||||
Handling multiple files as if they were part of a file system:
|
||||
|
||||
```typescript
|
||||
import { StreamFile } from '@push.rocks/smartfile';
|
||||
|
||||
// Creating a StreamFile from a file path (Async)
|
||||
const streamFile: StreamFile = await StreamFile.fromPath('./path/to/large/file.avi');
|
||||
|
||||
// Streaming file content to disk (Async)
|
||||
await streamFile.writeToDisk('./path/to/target/file.avi');
|
||||
const virtualDir = new VirtualDirectory();
|
||||
await virtualDir.addSmartfiles([smartFile1, smartFile2]);
|
||||
await virtualDir.saveToDisk('./virtualDirOutput');
|
||||
```
|
||||
|
||||
#### Utilizing Stream Files from URLs
|
||||
### File System Operations
|
||||
|
||||
`@push.rocks/smartfile` provides a suite of utilities for common file system operations such as copying, deleting, and listing files or directories.
|
||||
|
||||
#### Copying a File
|
||||
|
||||
```typescript
|
||||
import { StreamFile } from '@push.rocks/smartfile';
|
||||
|
||||
// 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();
|
||||
await fs.copy('./sourceFile.txt', './destinationFile.txt');
|
||||
```
|
||||
|
||||
### Handling Virtual Directories
|
||||
#### Deleting a Directory
|
||||
|
||||
```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');
|
||||
await fs.remove('./directoryToDelete');
|
||||
```
|
||||
|
||||
#### Manipulating File Paths
|
||||
#### Listing Files in a Directory
|
||||
|
||||
```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
|
||||
const fileList: string[] = await fs.listFiles('./someDirectory');
|
||||
console.log(fileList);
|
||||
```
|
||||
|
||||
### Security and Hashing
|
||||
### Advanced File Management
|
||||
|
||||
For specialized file operations, such as editing the contents of a file or streaming files from URLs, `@push.rocks/smartfile` includes advanced management features.
|
||||
|
||||
#### Editing a File’s Contents
|
||||
|
||||
```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'
|
||||
const smartFileToEdit: SmartFile = await SmartFile.fromFilePath('./editableFile.txt');
|
||||
await smartFileToEdit.editContentAsString((content) => content.replace(/originalText/g, 'newText'));
|
||||
await smartFileToEdit.write();
|
||||
```
|
||||
|
||||
### 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.
|
||||
#### Streaming a File from a URL
|
||||
|
||||
```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.');
|
||||
});
|
||||
const streamedFile: StreamFile = await StreamFile.fromUrl('https://example.com/file.pdf');
|
||||
await streamedFile.writeToDisk('./downloadedFiles/file.pdf');
|
||||
```
|
||||
