realpaths-callback

Callback-style version of realpaths:

Like fs.realpath, but resolves multiple paths at once

1const realpathsCallback = require('realpaths-callback');
2
3// symlink1 <<===>> /path/to/foo.txt
4// symlink2 <<===>> /path/to/bar.txt
5
6realpaths(['symlink1', 'symlink2'], (err, paths) => {
7  if (err) {
8    throw err;
9  }
10
11  paths; //=> ['/path/to/foo.txt', '/path/to/bar.txt']
12});

Installation

Use npm.

npm install realpaths-callback

API

1const realpathsCallback = require('realpaths-callback');

realpathsCallback(paths [, cache], callback)

paths: Array of strings (file paths)
cache: Object (used as fs.realpath cache)
callback: Function (called after the paths are resolved)

It's API is very similar to fs.realpath. The only difference is realpaths-callback takes an array as its first argument and resolves multiple paths at once.

1'use strict';
2
3const path = require('path');
4const realpaths = require('realpaths-callback');
5
6realpaths(['symlink1', 'symlink2'], {
7  cache: {
8    [path.resolve('symlink1')]: '/path/to/foo.txt',
9    [path.resolve('symlink2')]: '/path/to/bar.txt'
10  }
11}, (err, paths) => {
12  if (err) {
13    throw err;
14  }
15  paths; //=> ['/path/to/foo.txt', '/path/to/bar.txt']
16});

If at least one of the paths cannot be resolved, it immediately passes an error to its callback function without considering the rest of paths.
