node. JS Path Module

var path = require ('path'= {  './app/ Index.js',  output: {    'bundle.js',     ' Dist ' )  }};

When looking at some configuration files, such as webpack.config.js, often see the code above, sometimes tangled writing, in fact, this is the node. JS (Path module) provided by some of the small tools for processing the file path.

Some of the common uses are:

Method	Describe
Path.normalize (P)	Normalize paths
Path.join ([path1][, path2][, ...])	Used to connect the path. The main purpose of this method is to correctly use the path delimiter of the current system, the UNIX system is "/" and the Windows system is "\". The __dirname variable value represents the root directory in which the program runs
Path.resolve ([from ...], to)	Resolve to Absolute path
Path.extname (P)	Returns the suffix name of the file in the path
