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 🙏

为什么

已经有非常多的 cookie 相关工具了,甚至多年以前,在我初次接触 js 学习之处,也折腾过 COOKIE 这么个小玩意儿。

但是当我现在需要一个足够简单(现代 web 开发中,有着更多强大、丰富的本地存储方案,js 对于 cookie 的依赖越来越少)、支持标准的 cookie 工具时,我发现目前我能找到的各类 cookie 库(例如 js-cookiejquery-cookie甚至还有react-cookie???)都或多或少存在一些问题,有些破坏了标准,有些不支持较新的标准,有些是过度设计,过于繁重(COOKIE就是过度设计了)。

而直到我发现了 jshttp/cookie 这个标准库,虽然其是针对 HTTP cookies 规范定制,但是可以几乎完整适用于浏览器端。所以我基于该库做了稍微的修改定制,也就有了现在这个 cookick(名字由 cookiekick 组合而来)

安装

cookick

// use npm
$ npm install cookick --save

// use yarn
$ yarn add cookick

注意cookick也提供了umd格式的包,你可以将cookickumd包传到服务器上,然后通过script标签在页面中引入,直接通过window.cookick调用。

<!-- from self hosted cdn -->
<script src="{{ YOUR_CDN_URL }}/browser.umd.js"></script>

<!-- from unpkg -->
<script src="https://unpkg.com/cookick/dist/browser.umd.js"></script>

<!-- from jsDelivr -->
<script src="https://cdn.jsdelivr.net/npm/cookick/dist/browser.umd.js"></script>

运行环境要求

cookick支持在浏览器端和服务器端(express+Nodejs)运行。如果要在服务器端运行,需要在调用前挂载 middleware:

import { middleware } from 'cookick';

app.use(middleware);

nodejs 需要支持AsyncLocalStorage,最低版本要求为v12.17.0

如何使用

cookick提供了一组方法用于获取或者设置 cookie。浏览器和服务器端调用签名均完全一致,如果是 SSR,在组件中也可以放心调用

getCookie

declare function getCookie(name: string): string | undefined;

使用示例:

import { getCookie } from 'cookick';

getCookie('foo'); // 获取名称为 foo 的cookie

setCookie

interface CookieOptions {
    path?: string;
    domain?: string;
    expires?: Date; // 必须是Date对象
    maxAge?: number; // 整数,表示maxAge秒后过期。建议总是使用maxAge,不要使用expires。maxAge和expires如果同时存在,会忽略expires参数
    httpOnly?: boolean;
    secure?: boolean;
    sameSite?: boolean | 'lax' | 'strict' | 'none';
}

declare function setCookie(name: string, val: string | number, options?: CookieOptions): void;

使用示例:

import { setCookie } from 'cookick';

// 默认调用:在当前域下,path=/, 创建foo=bar的cookie
setCookie('foo', 'bar');

// 指定path参数
setCookie('foo', 'bar', {
    path: '/sub'
    // 甚至可以使用相对路径
    // path: '../another/sub'
});

// 设置doamin
setCookie('foo', 'bar', {
    domain: 'cookie.com'
});

// 设置过期时间,建议使用maxAge参数,设置过期秒数: https://javascript.info/cookie#expires-max-age
setCookie('foo', 'bar', {
    maxAge: 60 * 60 * 24 * 7
});

// 设置 secure、httpOnly、sameSite等
// 这些属性并不是所有浏览器都支持,有些目前仅在 server-http 协议支持,请使用前慎重考虑
setCookie('foo', 'bar', {
    secure: true,
    httpOnly: true,
    sameSite: 'strict'
});

delCookie

declare function delCookie(
    name: string,
    options?: {
        path?: string;
        domain?: string;
    }
): void;

使用示例:

import { delCookie } from 'cookick';

delCookie('foo'); // 删除名称为 foo 的cookie

// 如果cookie在其他子路径或者domain下,需要指定明确的path或者domain才能删除
delCookie('foo', {
    path: '/sub'
});

getAllCookies

declare function getAllCookies(): {
    [P: string]: string | undefined;
};

使用示例:

import { getAllCookies } from 'cookick';

getAllCookies(); // 解析所有的cookie为一个object对象

serialize

declare function serialize(name: string, val: string | number, options?: CookieOptions): string;

序列化一个新的 cookie 为字符串,你可以将其用于在服务端或者浏览器端设置 cookie:

const newCookieStr = serialize('foo', 'bar', {
    path: '/'
});

// 浏览器端
document.cookie = newCookieStr;

// 服务端
response.setHeader('set-cookie', newCookieStr);

setDefault

设置默认参数

declare function setDefault(options: CookieOptions): CookieOptions;

使用示例:

import { setDefault } from 'cookick';

// 在调用 setCookie 没有传递path、domain情况下,会总是将cookie根据默认参数进行设置
setDefault({
    path: '/basename',
    domain: '.root.domain'
});
