Node js Get folder path from a file
Is there a way to get the path to a folder that holds a particular file.
fs.realpathSync('config.json', []);
returns something like
G:\node-demos\7-node-module\demo\config.json
I just need
G:\node-demos\7-node-module\demo\
or
G:\node-demos\7-node-module\demo\
Is there any api for this or will I need to process the string?
Solution 1:
use path.dirname
// onlyPath should be G:\node-demos\7-handlebars-watch\demo
var onlyPath = require('path').dirname('G:\\node-demos\\7-node-module\\demo\\config.json');
Solution 2:
Simply install path
module and use it,
var path = require('path');
path.dirname('G:\\node-demos\\7-node-module\\demo\\config.json')
// Returns: 'G:\node-demos\7-node-module\demo'
Solution 3:
require("path").dirname(……)
breaks when your path does not explicitly specify its directory.
require("path").dirname("./..")
// "."
You may consider using require("path").join(……, "../")
instead. It preserves the trailing separator as well.
require("path").join("whatever/absolute/or/relative", "../")
// "whatever/absolute/or/" (POSIX)
// "whatever\\absolute\\or\\" (Windows)
require("path").join(".", "../")
// "../" (POSIX)
// "..\\" (Windows)
require("path").join("..", "../")
// "../../" (POSIX)
// "..\\..\\" (Windows)
require("path").win32.join("C:\\", "../")
// "C:\\"
