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 🙏

ts-totp

NPM version Known Vulnerabilities npm download

Description

Generate a dynamic password and verify that the password is valid within a specified time

Installation

  1. yarn add ts-totp

Description

// totp使用说明
import { getToken, validate } from 'ts-totp';
/**
 * @param {string} secret 密钥.
 * @param {number} [config.digits=6] 生成的token长度.
 * @param {number} [config.interval=60] 口令有效期,单位秒,默认60秒.
 */

// 生成动态口令
const token = getToken({ secret: 'K33DFSsasdassssVS', digits: 10, interval: 60 });
// token = 1950901855

// 校验口令
const res = validate(token, { secret: 'K33DFSsasdassssVS', digits: 10, interval: 60 });
// res = true
// 携带参数校验使用说明
import { getCode, validateCode } from 'ts-totp';
/**
 * prefix string 前缀
 * secret string 密钥
 * digits number 验证码位数
 * interval number 验证码有效时间
 * num number 验证数字(自动查找其临近的质数)
 * type string 质数查找方式(up/down)up:向上查找,小于该数的最大质数 down:向下查找,大于该数的最小质数
 * data number 携带的信息,比如用户ID.数字要小于num。如:当前系统设计最大承受用户有96742人,则num可以设定必须大于96742的数值(96743)
 */
const config = { prefix: '10', secret: 'K33DFSsssssVS', digits: 10, interval: 60, num: 96743, type: 'down' };
// 生成带参口令
const params = Object.assign({ data: 1002 }, config);
const code = getCode(params);
// code = 129477686511008

// 校验口令
const res = validateCode(code, config);
//成功 res = { message: 'success', data: 1002, token: 1338284494 }
//失败 res = { message: 'fail' }
