• Set Pre-Fix in unique IDs.
• Set Post-Fix in unique IDs.

• Now With Typescript Support 🥳

• Now any typescript based Environment can easily use unique-identity 🤩

Usage

//JavaScript
const id = require('unique-identity');
//Or
const { characters, get, setPostfix, setPrefix } = require('unique-identity');


console.log(id.get());
// De3MOQxCZAdHpvx3pG
// Bukc9IfvI8mh10PD5G
// D1kxsCOHcwrrfEDGpG
// VzS-0jSpkgQr7AD9G

//TypeScript
import { characters, get, setPostfix, setPrefix } from 'unique-identity';
//Or
import * as id from 'unique-identity';
//Or
import id from 'unique-identity';

console.log(id.get());
// De3MOQxCZAdHpvx3pG
// Bukc9IfvI8mh10PD5G
// D1kxsCOHcwrrfEDGpG

Mongoose Unique Id

_id: {
  'type': String,
  'default': id.get()
},

API

//JavaScript
const id = require('unique-identity');
//Or
const { characters, get, setPostfix, setPrefix } = require('unique-identity');

//TypeScript
import { characters, get, setPostfix, setPrefix } from 'unique-identity';
//Or
import * as id from 'unique-identity';
//Or
import id from 'unique-identity';

Example

users.insert({
  _id: id.get(),
  name: '...',
  email: '...'
});

You can also set your custom 64 unique characters then unique id will be generated accordingly.

Example

//JavaScript
const id = require('unique-identity');
//Or
const { characters, get, setPostfix, setPrefix } = require('unique-identity');

//TypeScript
import { characters, get, setPostfix, setPrefix } from 'unique-identity';
//Or
import * as id from 'unique-identity';
//Or
import id from 'unique-identity';

let characters='0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-_';
id.characters(characters);

console.log(id.characters(characters));
// { status : true }

console.log(id.characters('duplicate characters of string'));
// { message: 'Duplicate characters found.', status: false }

console.log(id.characters('wrong length of string'));
// { message: 'Need 64 unique characters.', status: false }

You can also set the Pre-Fix and Post-Fix characters too and the unique id will be generated accordingly.

Example

//JavaScript
const id = require('unique-identity');
//Or
const { characters, get, setPostfix, setPrefix } = require('unique-identity');

//TypeScript
import { characters, get, setPostfix, setPrefix } from 'unique-identity';
//Or
import * as id from 'unique-identity';
//Or
import id from 'unique-identity';

// To Set Pre-Fix

id.setPrefix(inputString);

console.log(id.setPrefix(inputString));
// { status : true }

console.log(id.setPrefix(/*invalid type input*/));
// { message: 'Invalid input type, Required string.', status: false }

console.log(id.setPrefix(/*input string length more than 50 chars*/));
// { message: 'Max chars limit is 50.', status: false }


// To Set Post-Fix

id.setPostfix(inputString);

console.log(id.setPostfix(inputString));
// { status : true }

console.log(id.setPostfix(/*invalid type input*/));
// { message: 'Invalid input type, Required string.', status: false }

console.log(id.setPostfix(/*input string length more than 50 chars*/));
// { message: 'Max chars limit is 50.', status: false }

Pre-Fix & Post-Fix Examples

//Pre-Fix

id.setPrefix('SKU_');
console.log(id.get());
// SKU_De3MOQxCZAdHpvx3pG
// SKU_Bukc9IfvI8mh10PD5G
// SKU_D1kxsCOHcwrrfEDGpG


//Post-Fix

id.setPostfix('_postFix');
console.log(id.get());
// De3MOQxCZAdHpvx3pG_postFix
// Bukc9IfvI8mh10PD5G_postFix
// D1kxsCOHcwrrfEDGpG_postFix


//For Both
id.setPrefix('SKU_');
id.setPostfix('_postFix');

console.log(id.get());
// SKU_De3MOQxCZAdHpvx3pG_postFix
// SKU_Bukc9IfvI8mh10PD5G_postFix
// SKU_D1kxsCOHcwrrfEDGpG_postFix

//To Unset the Pre-Fix or Post-Fix

id.setPrefix('');// it will unset prefix
id.setPostfix('');// it will unset postfix
