lodash.uniqueid

What is lodash.uniqueid?

The lodash.uniqueid package is a utility function from the Lodash library that generates unique IDs. It is useful for creating unique identifiers for elements, objects, or any other entities that require a unique reference.

What are lodash.uniqueid's main functionalities?

Generate Unique ID

This feature allows you to generate a unique ID with an optional prefix. The generated ID is a string that combines the prefix with an incrementing number.

const _ = require('lodash.uniqueid');
const uniqueId = _.uniqueId('prefix_');
console.log(uniqueId); // 'prefix_1'

Multiple Unique IDs

This feature demonstrates generating multiple unique IDs with the same prefix. Each call to _.uniqueId with the same prefix will generate a new unique ID.

const _ = require('lodash.uniqueid');
const id1 = _.uniqueId('item_');
const id2 = _.uniqueId('item_');
console.log(id1); // 'item_1'
console.log(id2); // 'item_2'

Other packages similar to lodash.uniqueid

uuid

The 'uuid' package is a popular library for generating RFC4122 UUIDs (Universally Unique Identifiers). Unlike lodash.uniqueid, which generates simple incrementing IDs, 'uuid' generates more complex and globally unique identifiers. It is suitable for use cases where a higher degree of uniqueness is required.

nanoid

The 'nanoid' package is a small, secure, URL-friendly unique string ID generator. It is faster and smaller than 'uuid' and provides a higher degree of uniqueness compared to lodash.uniqueid. It is ideal for use cases where performance and security are critical.

shortid

The 'shortid' package is a short, non-sequential, URL-friendly unique ID generator. It is designed to be simple and easy to use, providing shorter IDs compared to 'uuid' and 'nanoid'. It is a good alternative to lodash.uniqueid for generating shorter unique IDs.
