The tutorial provides the details on the node.js path module. The node.js path module provides the utilization for working with the file path and directory path. The node.js path module can be accessed using the command

const path = require('path');

There will be path variation when node.js is running on different operating system. To achieve same path execution output path.win32 should be used.

Node.js Path methods

Path Method	Path Method Description
path.basename(path[, ext])	execution behaviour is similar to unix base command where it returns the last portion of the path path – <string> ext – <string> file extension (optional) returns – <string> path.basename(‘/tmp/nodejs/path/pathbasename.html’); // Returns: ‘pathbasename.html’
path.delimiter	uses the type as <string> and provides different path specific delimiter ; for windows : for POSIX console.log(process.env.PATH); // Returns: ‘/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin’ console.log(process.env.PATH); // Returns: ‘C:\Windows\system32;C:\Windows;C:\Program Files\node\’
path.dirname(path)	execution behaviour is similar to unix base command where it returns the directory name of the path path – <string> returns – <string> path.dirname(‘/tmp/nodejs/path/pathdir.html’); // Returns: ‘/tmp/nodejs/path’
path.extname(path)	execution behaviour is similar to unix base command where it returns the extension of the path path – <string> returns – <string> path.dirname(‘/tmp/nodejs/path/pathdir.html’); // Returns: ‘.html’
path.isabsolute(path)	indicates if path is an absolute path. path – <string> return – boolean path.isAbsolute(‘//nodeServer’); // true path.isAbsolute(‘node/path’); // false path.isAbsolute(‘.’); // false
path.relative(from, to)	solves the relative path from “from” to “to” from <string> to <string> return <string> path.relative(‘/data/node/path/relative’, ‘/data/node/tmp/absolute’); // Returns: ‘../../tmp/absolute’
path.join([path1][, path2][, …])	join all path segments using delimiter and returns the normalized resulting path path – <string> –sequence of path segments returns – <string> — normalized resulting path path.join(‘/tmp’, ‘node’, ‘path/sample’, ‘..’); // Returns: ‘/tmp/node/path/sample’
path.normalize(p)	normalize a string path, taking care of ‘..’ and ‘.’ parts path – <string> returns – <string> path.normalize(‘C:\tmp\\node\path\..\’); // Returns: ‘C:\tmp\node\’
path.parse(pathstring)	returns the object from the path string path – <string> returns – <string> where return object could have dir <string> root <string> base <string> name <string> ext <string> On Windows: path.parse(‘C:\tmp\node\pathParsing.txt’); // Returns: // { root: ‘C:\’, // dir: ‘C:\temp\node’, // base: ‘pathParsing.txt’, // ext: ‘.txt’, // name: ‘file’ }
path.format(pathObject)	returns the path string from the object where pathObject could have dir <string> root <string> base <string> name <string> ext <string> pathObject.root is ignored if pathObject.dir is provided pathObject.ext and pathObject.name are ignored if pathObject.base exists On Windows: path.format({ dir: ‘C:\node\pathdir’, base: ‘pathexample.txt’ }); // Returns: ‘C:\node\pathdir\pathexample.txt’
