The fs.readlinkSync() method is an inbuilt application programming interface of fs module which is used to synchronously return a symbolic link’s value, i.e. the path it is linked to. The optional argument can be used to specify the character encoding of the link path.
Syntax:
fs.readlinkSync( path, options )
Parameters: This method accepts two parameters as mentioned above and described below:
- path: It is a String, Buffer or URL which represents the path of the symbolic link.
- options: It is an object or String that can be used to specify optional parameters that will affect the output. It has one optional parameter:
- encoding: It is a string value which specifies the character encoding in which the link path is returned. The default value is ‘utf8’.
Below examples illustrate the fs.readlinkSync() method in Node.js:
Example 1:
const fs = require( 'fs' );
fs.symlinkSync(__dirname + "\\example_file.txt" ,
"symlinkToFile" , 'file' );
console.log( "\nSymlink created\n" );
symlinkPath = fs.readlinkSync( "symlinkToFile" );
console.log( "Path of the symlink:" , symlinkPath);
|
Output:
Symlink created
Path of the symlink: G:\tutorials\nodejs-fs-readlinkSync\example_file.txt
Example 2: This example creates a symlink to a directory.
const fs = require( 'fs' );
fs.symlinkSync(__dirname +
"\\example_directory" , "symlinkToDir" , 'dir' );
console.log( "\nSymlink created\n" );
symlinkPath = fs.readlinkSync( "symlinkToDir" );
console.log( "Path of the symlink:" , symlinkPath);
|
Output:
Symlink created
Path of the symlink: G:\tutorials\nodejs-fs-readlinkSync\example_directory
