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 🙏

RcGroup - 分组类元素

可以支持RadioGroup、CheckboxGroup、Tabs、Tag List等组件。 方便进行父子之间通信。

API

RcGroup

分组容器,处于同一个容器下的组件会被当成是一组,支持所有div元素支持的属性。

  • 定义 function RcGroup<T, P>(props: IRcGroupProps<T, P>): React.ReactNode

  • 类型

    • IRcGroupProps type IRcGroupProps<T, P> = UnionOmit<IGroupOptions<T, P>, HTMLAttributes<HTMLDivElement>>
    • IGroupOptions interface IGroupOptions<T, P> {disabled: boolean;extraProps: P;value: T[];onChange: (value: T[]) => void;}
  • 泛型参数

    • T 表示分组中值可能为的类型
    • P 表示所有可以在容器和子项之间共享的属性,设置在P中的属性会进行容器和子项的合并(子项目高于容器)由于disabled影响行为,所以直接在IGroupOptions中做了定义
  • 用法

    import React, {useMemo, HTMLAttributes} from 'react'
    import {ComponentSize, UnionOmit} from '@co-hooks/util'
    import {RcGroup} from '@rc-hooks/group'

    interface ICheckboxButtonGroupShareOptions {
        size: ComponentSize; // 用于表示按钮大小
        type: string; // 用于表示按钮类型
    } 
    
    interface ICheckboxButtonGroup<T> extends Partial<ICheckboxButtonGroupShareOptions> {
        value: T[]
        onChange: (value: T[]) => void;
        disabled?: boolean;
    }
     
    type ICheckboxButtonGroupProps<T> = UnionOmit<ICheckboxButtonGroup<T>, HTMLAttributes<HTMLDivElement>>;

    function CheckboxButtonGroup<T>(props: ICheckboxButtonGroupProps<T>) {
        
        const {
            value,
            type = 'default',
            size = 'md',
            disabled = false,
            onChange,
            ...others
        } = props;
        
        const extraProps = useMemo(() => ({size, type}), [size, type]);
        
        return (
            <RcGroup<T, ICheckboxButtonGroupShareOptions>
                {...others}
                value={value}
                onChange={onChange}
                disabled={disabled}
                extraProps={extraProps}
            />
        )
    }

由于要支持单选、多选、混选等多种情况,所有数值都以数组的形式提供,如须单值,可以如下自行封装相关属性

    
    import {useCallback} from 'react'
    
    
    function RadioGroup<T>(props:{onChange: (value: T | null) => void}) {
    
         const onChange = useCallback((value: T[]) => {
              props.onChange(value.length ? value[0]: null);
          }, [props.onChange])
    }

useGroupItem

分组子项使用的钩子,可以用于获取子项目使用到的信息。

  • 定义 function useGroupItem<T, P>(props: IGroupItemOptions<T, P>): IGroupItemRenderProps<T, P>
  • 类型
    • IGroupItemRenderProps type IGroupItemRenderProps<T, P> = [UnionOmit<{checked: boolean; disabled: boolean}, P>, (checked: boolean) => void ]
    • IGroupItemOptions interface IGroupItemOptions<T, P> {disabled: boolean; extraProps: Partial<P>; group: string; free: boolean; value: T}
  • 泛型参数
    • T 表示分组中值可能为的类型
    • P 表示所有可以在容器和子项之间共享的属性,设置在P中的属性会进行容器和子项的合并(子项目高于容器)由于disabled影响行为,所以直接在IGroupOptions中做了定义
  • 用法
    import React, {ButtonHTMLAttributes, useCallback, MouseEventHandler} from 'react'
    import {ComponentSize, UnionOmit} from '@co-hooks/util'
    import {useGroupItem} from '@rc-hooks/group'

    interface ICheckboxButtonGroupShareOptions {
        size: ComponentSize; // 用于表示按钮大小
        type: string; // 用于表示按钮类型
    } 
    
    interface ICheckboxButton<T> extends Partial<ICheckboxButtonGroupShareOptions> {
        value: T[]
        disabled?: boolean;
    }
     
    type ICheckboxButtonProps<T> = UnionOmit<ICheckboxButton<T>, ButtonHTMLAttributes<HTMLButtonElement>>;

    function CheckboxButton<T>(props: ICheckboxButtonProps<T>) {
        
        const {
            value,
            type, 
            size,
            disabled = false,
            onClick, // Button没有onChange事件,用onClick来模拟
            ...others
        } = props;
        
        const [group, onItemChange] = useGroupItem<T, ICheckboxButtonGroupShareOptions>({
            disabled,
            value,
            group: 'checkbox', // 所有的项目都在一个分组,用同一个就可以了
            free: false,
            // 这里有个partial可以传递部分属性
            extraProps:{
                size, 
                type
            }
        });
        
        // 省略了type size等样式处理函数,也可以单独封装一个组件来处理
        
        const onButtonClick = useCallback((e: MouseEventHandler<HTMLButtonElement>) => {
            
            if(onClick) {
                onClick(e);
            }
            
            // 对于checkbox来说,点一下翻转
            onItemChange(!group.checked);
        }, [onClick, onItemChange, group.checked]);
        
        return (
            <button {...others} onClick={onButtonClick}/>
        )
    }
