how to use the linksync function from fs-extra in javascript

To use the linksync function from fs-extra in Node.js, follow these steps:

1. Install fs-extra using npm:

npm install fs-extra
21 chars
2 lines

2. Import fs-extra into your Node.js script using require:

index.tsx
const fs = require('fs-extra');
32 chars
2 lines

3. Call the linksync function with the source and destination file paths:

index.tsx
const srcPath = '/path/to/source/file';
const destPath = '/path/to/destination/file';

fs.linkSync(srcPath, destPath);
119 chars
5 lines

This will create a hard link from the srcPath file to the destPath file. If the destination file already exists, it will be overwritten.

Here's an example that checks if the destination file already exists and deletes it if it does:

index.tsx
const fs = require('fs-extra');
const path = require('path');

const srcPath = '/path/to/source/file';
const destPath = '/path/to/destination/file';

if (fs.existsSync(destPath)) {
  fs.unlinkSync(destPath);
}

fs.linkSync(srcPath, destPath);

console.log(`Created hard link from ${path.basename(srcPath)} to ${path.basename(destPath)}.`);

14 lines

This code will create a hard link from the srcPath file to the destPath file and log a message to the console. If the destPath file already exists, it will be deleted before the link is created.
