fsxu

node-fsxu

fsxu is minimal set of filesystem utility functions inspired by fs-extra

Installation

npm install --save fsxu

Usage

listDirSync(path)

listDirSync works like readdirSync function, but returns path+name array instead just names. So you can work with files without joining path. Returns null

var fsxu = require('fsxu');
 
fsxu.listDirSync('my/path'); //['my/path/file.json', 'my/path/dir01']
 
fsxu.listDirSync('path/does/not/exist'); //null

makeDirSync(path)

makeDirSync works like mkdir -p command. It recursively creates directories. Works with absolute and relative paths. Returns true if everything was ok.

var fsxu = require('fsxu');
 
fsxu.makeDirSync('create/deep/nested/path'); //true

findUpSync(name[, path])

findUpSync searches for file or directory starting from path or __dirname, and going up, until it reaches filesystem root. Once found, the absolute path is returned, otherwise null.

var fsxu = require('fsxu');
 
//get project root directory
var rootDir = fsxu.findUpSync('package.json'); // '/Users/psxcode/dev/my-proj'
 
var filepath = fsxu.findUpSync('config.json', 'search/from/here'); // '/Users/psxcode/dev/my-proj/search'

isFileSync(filepath)

isFileSync returns true if path provided is a file

var fsxu = require('fsxu');
 
//check if file exists
fsxu.isFileSync('path/to/my/file.json')); //true //file exists
 
//get only files listed in directory
var files = fsxu.listDirSync('path/to/my/files').filter(fsxu.isFileSync);

isDirSync(path)

isDirSync returns true if path provided is a directory

var fsxu = require('fsxu');
 
//check if directory exists
fsxu.isDirSync('path/to/my/dir')); // true //directory exists 
 
//get only directories listed in directory
var files = fsxu.listDirSync('path/to/my/dir').filter(fsxu.isDirSync);

emptyDirSync(path)

emptyDirSync ensures that a directory is empty. Deletes directory contents if the directory is not empty. If the directory does not exist, it is created. The directory itself is not deleted. Returns true if everything was ok.

var fsxu = require('fsxu');
 
fsxu.emptyDirSync('relative-path-to-my-dir'); //true
 
fsxu.emptyDirSync('/absolute/path/to/my/dir'); //true

rmDirSync(path[, recursive])

rmDirSync removes directory. If recursive is set to true recursively removes all content, and then the directory. Returns true if directory does not exist or if removal was successfull.

var fsxu = require('fsxu');
 
//try to remove
fsxu.rmDirSync('path/to/my/dir'); // false //directory is not empty
 
//use recursive option
fsxu.rmDirSync('path/to/my/dir', true); //true //now removed 
 

rmFileSync(pathname)

rmFileSync removes file. Returns true if file does not exist or if removal was successfull.

var fsxu = require('fsxu');
 
//try to remove
fsxu.rmFileSync('path/to/my/file.json'); // true //file removed
 
//ensure removed
fsxu.rmFileSync('path/to/my/file.json'); //true //does not exist 
 

rmSync(pathname[, recursive])

rmSync removes file or directory. If target is directory and recursive is set to true recursively removes all content, and then the directory. Returns true if target does not exist or if removal was successfull.

var fsxu = require('fsxu');
 
//try to remove
fsxu.rmSync('path/to/my/file.json'); // true //file removed
 
//ensure removed
fsxu.rmSync('path', true); //true //recursively removes everything in 'path' and the 'path' itself.
 

readJsonSync(filepath)

readJsonSync returns parsed JSON content. Returns null if something was wrong.

var fsxu = require('fsxu');
 
var jsonObj = fsxu.readJsonSync('path/to/file.json');
if(jsonObj) {
  //use the object
}

writeJsonSync(filepath, object)

writeJsonSync stringifies object and writes it to .json file. If the directory does not exist, it is created. Returns true if write was successfull.

var fsxu = require('fsxu');
 
var jsonObj = {
  name: 'alex',
  hobby: 'javascript'
};
 
fsxu.writeJsonSync('path/to/file.json', jsonObj); //true
