Path. Resolve method in node.js

Method description:

Parses the character of the argument to position into an absolute path.

Grammar:

path.resolve([from ...], to)

Since this method belongs to the path module, you need to introduce the path module (var path= require(" path ")) before using it.

Receiving parameters:

From                                        The source path
To                                                The string that will be parsed to the absolute path

Example:

path.resolve('/foo/bar', './baz')

 

// returns

 

'/foo/bar/baz'

 

path.resolve('/foo/bar', '/tmp/file/')

 

// returns

 

'/tmp/file'

 

path.resolve('wwwroot', 'static_files/png/', '../gif/image.gif')

 

// if currently in /home/myself/node, it returns

 

'/home/myself/node/wwwroot/static_files/gif/image.gif'

Another way is to use it as a sequential CD command shell.

path.resolve('foo/bar', '/tmp/file/', '..', 'a/../subfile')

Similar to:

cd foo/bar

cd /tmp/file/

cd ..

cd a/../subfile

pwd
