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 🙏

NPM Package Quality

node useful toolkit. 封装了常用的 nodejs 工具包,如配置加载,加密和字符串转换等。

Getting Started

yarn add node-buffs
const { createConfigLoader } = require('node-buffs');
// or
import { createConfigLoader } from 'node-buffs';

模块

ConfigLoader

一个灵活配置读取器,通过环境变量 ENV 加载对应的 dotenv 文件,也可通过预制的优先级覆盖配置。

  • ENV=undefined -> .env
  • ENV=local -> .env.local
  • ENV=staging -> .env.staging

加载优先级: overwrite options -> process.env -> options(.env) -> optionsLoader -> default

e.g:

  • set required, will throw exceptions at startup when variable cannot found in .env or environments
import { createConfigLoader } from 'node-buffs';

// Load order:
// 1. load from overwrite options
// 2. load from process.env
// 3. load from .env
// 4. load from optionsLoader (json or function)
// 5. load from default

// lv4
export const configLoader = createConfigLoader({
  optionsLoader: { data: 'o.o' },
  requiredVariables: ['SECRET_KEY'],
});

// 具有最高的优先级 lv1
configLoader.setOverwriteOptions({
  highestOrder: '^_^',
});

// lv5
const key = configLoader.loadConfig('SECRET_KEY', 'default-secret');
const configs = configLoader.loadConfigs();
