nodupes

Prevent duplicate names by appending an incremented prefix.

Examples

example/nodupes.js

var nodupes = require('nodupes')();
var names = ['name', 'name', 'othername', 'name', 'othername'];
names.forEach(function(name) {
  console.log( nodupes(name) );
});

Output:

$ node example/nodupes.js
name
name-2
othername
name-3
othername-2

Usage

var nodupes = require('nodupes');

var nd = nodupes(options)

Call nodupes() to get a new nodupes function, with its own index and options.

Options:

var options = {
  names: {},           // Load a pre-existing names index.
  suffixFirst: false,  // Add a suffix on the first appearance of a name.
  separator: '-'       // Change the suffix separator.
};

nd('name')

Returns the name with an appended suffix if needed.

Installation

$ npm install nodupes
