src/components/StampBadge/src/props.ts 文件代码

export const stampBadgeProps = {
  color: {
    type: String,
    default: "primary",
    validator: (v) =>
      ["primary", "error", "warning", "success", "info"].includes(v),

   * @default: 0
   */
  rotate: { type: Number, default: 0 },
  content: { type: String, default: "Unknown" },
};

src/components/StampBadge/index.ts 文件代码

import { withInstall } from "/@/utils";
import type { ExtractPropTypes } from "vue";
import stampbadge from "./src/StampBadge.vue";
import { stampBadgeProps } from "./src/props";

export const StampBadge = withInstall(stampbadge);
export declare type ButtonProps = Partial<
  ExtractPropTypes<typeof stampBadgeProps>
>;

src/utils/index.ts 文件代码

export const withInstall = <T>(component: T, alias?: string) => {
  const comp = component as any;
  comp.install = (app: App) => {
    app.component(comp.name || comp.displayName, component);
    if (alias) {
      app.config.globalProperties[alias] = component;
    }
  };
  return component as T & Plugin;
};

二、组件全局注册代码

src/components/registerGlobComp.ts 文件代码

import type { App } from "vue";
import { StampBadge } from "./StampBadge";

export function registerGlobComp(app: App) {
  app.use(StampBadge);
}

src/main.ts 文件代码

import { createApp } from "vue";
import App from "./App.vue";
import { registerGlobComp } from "/@/components/registerGlobComp";

async function bootstrap() {
  // 创建应用实例
  const app = createApp(App);
  // 注册全局组件
  registerGlobComp(app);
  // 挂载应用
  app.mount("#app", true);
}

bootstrap();

三、组件应用代码

<div >
  <StampBadge
    
    size="middle"
    color="success"
    content="已建档"
    :rotate="45"
  />
</div>
