What is uniqid?

The uniqid npm package is a simple utility for generating unique IDs based on the current time, process ID, and a random number. It is useful for creating unique identifiers for objects, database entries, or any other entities that require a unique ID.

What are uniqid's main functionalities?

Basic Unique ID Generation

Generates a unique ID using the default settings. This ID is based on the current time, process ID, and a random number.

const uniqid = require('uniqid');
const id = uniqid();
console.log(id);

Unique ID with Prefix

Generates a unique ID with a specified prefix. This can be useful for categorizing or identifying the source of the ID.

const uniqid = require('uniqid');
const idWithPrefix = uniqid('prefix-');
console.log(idWithPrefix);

Unique ID with Suffix

Generates a unique ID with a specified suffix. This can be useful for adding additional context or information to the ID.

const uniqid = require('uniqid');
const idWithSuffix = uniqid('', '-suffix');
console.log(idWithSuffix);

Unique ID with Both Prefix and Suffix

Generates a unique ID with both a specified prefix and suffix. This provides maximum flexibility for customizing the ID format.

const uniqid = require('uniqid');
const idWithBoth = uniqid('prefix-', '-suffix');
console.log(idWithBoth);
