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 🙏

@tntd/utils

TNTD前端业务代码工具库 支持TS引用

utils npm download MIT

目的:我们把业务开发中常用的工具类函数,统一封装到@tntd/utils包下,以提高开发效率。

🏗️ 安装使用

$ npm install @tntd/utils
import { getCookie } from "@tntd/utils";

const cookie = getCookie("test");

🌽 按需加载方法1

安装 babel-plugin-import

npm install babel-plugin-import -save-dev

新建 .babelrc 文件,如果有则跳过

{
    "plugins": [
        // 如下是babel-plugin-import插件的配置
        [
            "import", {
                "libraryName": "@tntd/utils",   // 要实现按需加载的库名
                "camel2DashComponentName": false    // 是否要把组件的目录名改成小写形式,即my-button,默认为true
            }, 
            // 如果你的@babel版本低于7,这句配置不用写
            "@tntd/utils"
        ]
    ]
}

🌽 按需加载方法2

安装tntdbabel插件

$ npm install babel-plugin-tntd-utils --save-dev

.babelrc中添加如下配置即可

"plugins": [
