Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

create-random-string

v1.0.4

Published

Generate random string by given length or mask

Readme

create-random-string

This module lets you create random strings by masks

Install

$ npm install create-random-string

Usage

Simply call the function with or without any arguments

For example,

var crs = require('create-random-string');

crs();
// 9a4BMrv7uFfYozqbRHnqL10tM6Y6z9MUvWhtZIxP8xhyBlOJC0Jgfyf1C1rNh9Vj

// without any arg it will return a 64 characters long random string - containing [A-z0-9]

You can specify the length of the string by providing a number

crs(12);
// y31g45FDvZjB

You can use masks. x stands for small letters, X for capital letters and 0 is for digits.

crs("xxxx-XXXX.0000");
// rfrg-PTSO.4601

// as you can see the dividers are remaining on their position

If you need longer strings you can define the character type and the length within brackets.

crs("(x|9)");
// jratgqkgl

crs("(xX|9)");
// vbcfpHNUc

crs("(xX0|9)");
// r9Myxp224

crs("(xX|9)-(x0|9)-(X|9):(0|9)-(0X|9)-(xX0|9)");
