crypto-random-string

What is crypto-random-string?

The crypto-random-string package is a utility for generating cryptographically strong random strings of a specified length, using Node.js's crypto module. It can be used for creating unique identifiers, tokens, or any other use cases where random strings are needed.

What are crypto-random-string's main functionalities?

Generating a random string of a specified length

This feature allows you to generate a random string with a specified length. The length is provided as an option in an object passed to the function.

const cryptoRandomString = require('crypto-random-string');

const randomString = cryptoRandomString({length: 10});
console.log(randomString);

Generating a random string with a specific type

This feature allows you to generate a random string with a specific character set, such as alphanumeric, numeric, or 'url-safe' characters.

const cryptoRandomString = require('crypto-random-string');

const alphanumericString = cryptoRandomString({length: 10, type: 'alphanumeric'});
console.log(alphanumericString);

Generating a random string with custom characters

This feature allows you to generate a random string using a custom set of characters provided by the user.

const cryptoRandomString = require('crypto-random-string');

const customString = cryptoRandomString({length: 10, characters: 'abc123'});
console.log(customString);

Other packages similar to crypto-random-string

uuid

The uuid package is used to generate universally unique identifiers (UUIDs). While crypto-random-string generates random strings of a specified length, uuid generates strings in a specific UUID format. UUIDs are often used as database keys, component identifiers, or to ensure uniqueness across distributed systems.

nanoid

NanoID is a tiny, secure, URL-friendly, unique string ID generator. Similar to crypto-random-string, it can generate random strings of various lengths and character sets. NanoID claims to be a more compact and faster alternative to UUIDs and has a smaller package size compared to crypto-random-string.

randomatic

Randomatic is a package that generates random strings based on patterns. It allows for more complex patterns and masks than crypto-random-string, such as repeating sequences and placeholders for specific character types (letters, numbers, etc.). This package offers more granular control over the structure of the generated string.
