graceful-readlink

What is graceful-readlink?

The graceful-readlink npm package provides a way to read symbolic links in a manner that gracefully handles errors and edge cases. It is designed to be a more robust alternative to the standard fs.readlink method in Node.js.

What are graceful-readlink's main functionalities?

Reading Symbolic Links

This feature allows you to read the target of a symbolic link synchronously. The code sample demonstrates how to use the graceful-readlink package to read a symbolic link and print its target path.

const readlink = require('graceful-readlink');
const linkPath = '/path/to/symlink';
const targetPath = readlink.sync(linkPath);
console.log(targetPath);

Graceful Error Handling

This feature ensures that errors are handled gracefully when reading symbolic links. The code sample shows how to use a try-catch block to handle potential errors that may occur during the read operation.

const readlink = require('graceful-readlink');
const linkPath = '/path/to/symlink';
try {
  const targetPath = readlink.sync(linkPath);
  console.log(targetPath);
} catch (err) {
  console.error('Error reading symbolic link:', err);
}
