NextJS开发：shadcn/ui中Button组件扩展增加图标
shadcn/ui组件比较灵活，但是功能相比ant之类组件还是缺少太多功能，本文为shadcn/ui为button组件增加图标，加载中动画等效果。
- 安装Lucide
npm install lucide
- Lucide组件
import { cn } from '@/lib/utils';
import { icons } from 'lucide-react';const LcIcon = ({ name, color, size, className }: { name: string, color?: string, size: number, className?: string}) => {const LucideIcon = (icons as any)[name];if(LucideIcon == null) {return <></>}if(color != null) {return <LucideIcon color={color} size={size} />} else {return <LucideIcon size={size} className={cn("", className)}/>}
};export default LcIcon;
- 创建组件CustomButton
"use client"
import React, { MouseEventHandler } from "react";
import { Button } from "../ui/button";
import LcIcon from "./lc-icon";/** * Button扩展，增加图标功能 * <CustomButton icon="Loader" onClick={handleSubmit}>Button</CustomButton>* */
export const CustomButton = (props: {className?: string, icon?: string, loading?: booleandisabled?: boolean,type?: string,onClick?: MouseEventHandler<HTMLButtonElement>,children?: any
}) => {const buildIcon = () => {if(props.loading != null && props.loading) {return <LcIcon name="Loader" size={16} className="mr-1 animate-spin"/>}else if(props.icon != null) {return <LcIcon name={props.icon} size={16} className="mr-1"/>}return ""}return (<Button type={props.type ?? 'button' as any} className={props.className} disabled={props.disabled} onClick={props.onClick}>{ buildIcon() }{ props.children }</Button>)
}
- 组件使用，
显示加载中
import { CustomButton } from "@/components/app/custom-button";<CustomButton loading={true} disabled={true} >测试</CustomButton>
显示图标
import { CustomButton } from "@/components/app/custom-button";<CustomButton icon="Home">测试</CustomButton>
