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 🙏

react-hooks useStorage

Readme

@tgu/useStorage

本地数据缓存

import { useStorageState } from '@tgu/usestorage'

Example

import { useSessionStorageState } from '@tgu/usestorage'
const [userInfo, setUserInfo] = useSessionStorageState<any>('userInfo', {})
setUserInfo({ userId: 1 })
consle.log('userInfo: ', userInfo)

useStorage

useStorage是前端缓存库 - 可以使用localstorage/sessionstorage,也可以使用自定义的cacheStorage

Usage

const [state, updateStateFn, deleteStateFn] = useStorageState([cacheStorage], key, defaultValue)

Params

| Property | Description | Type | Default | Required | | ---- | ---- | ---- | ---- | ---- | | cacheStorage | 缓存类库 | Storage | null | true | | key | 缓存字段名 | string | null | true | | defaultValue | 默认参数 | any | null | false |

Result

| Property | Description | Type | Required | | ---- | ---- | ---- | ---- | | state | 状态 | any | true | | updateState | 更新状态的方法 | function | false | | deleteState | 删除状态的方法 | function | false |

Storage

自己封装的cacheStorage必须要带有一下方法

| API | Description | Params | | ---- | ---- | ---- | | getItem | 获取缓存方法 | key | | setItem | 设置缓存方法 | key, value | | removeItem | 移除缓存方法 | key | | clear | 清除所有缓存方法 | null | | updateLength | 更新缓存长度 | null | | key | 根据设置缓存的索引获取缓存key | index |


altStorageState

altStorageState 的使用方法与 useStorageState 完全一致,唯一的区别在于 useStorageState是以react的hooks方式使用,altStorageState是在非hooks版本中使用

其它storage

以useLocalStorageState为例

Usage

const [state, updateStateFn, deleteStateFn] = useLocalStorageState(key, defaultValue)

Params

| Property | Description | Type | Default | Required | | ---- | ---- | ---- | ---- | ---- | | key | 缓存字段名 | string | null | true | | defaultValue | 默认参数 | any | null | false |

Result

| Property | Description | Type | Required | | ---- | ---- | ---- | ---- | | state | 状态 | any | true | | updateState | 更新状态的方法 | function | false | | deleteState | 删除状态的方法 | function | false |


其它

还支持的API用法与useLocalStorageState完全一致。唯二区别:

  1. alt/use 函数用法/hooks用法
  2. [use/alt][StorageType]state, StorageType表示对应的缓存库

| API | Description | | ---- | ---- | | useLocalStorageState | hooks使用localstorage缓存 | | altLocalStorageState | 非hooks使用localstorage缓存 | | useSessionStorageState | hooks使用sessionstorage缓存 | | altSessionStorageState | 非hooks使用sessionstorage缓存 | | usecacheStorageState | hooks使用自定义的map缓存 | | altCacheStorageState | 非hooks使用自定义的map缓存 |
