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 🙏

基于 iframe 的父窗口和子窗口的通讯机制实现,支持 React 和 Vue 3。

Readme

@genee/uno-webview

基于 iframe 的父窗口和子窗口的通讯机制实现,支持 React 和 Vue 3。

安装

npm install @genee/uno-webview

使用方式

React Hooks (默认)

import { useUno, useUnoParams, useUnoGlobals } from '@genee/uno-webview';

function MyComponent() {
    const uno = useUno();
    const params = useUnoParams();
    const globals = useUnoGlobals();

    // 事件订阅
    useUnoEvent('customEvent', (data) => {
        console.log('Received event:', data);
    });

    // 方法创建
    useUnoMethod('customMethod', (param) => {
        console.log('Method called with:', param);
        return 'response';
    });

    // 使用逻辑
    return <div>Hello World</div>;
}

Vue 3 Composition API

import { useUno, useUnoParams, useUnoGlobals, useUnoEvent, useUnoMethod } from '@genee/uno-webview/vue';

export default {
    setup() {
        const uno = useUno();
        const params = useUnoParams();
        const globals = useUnoGlobals();

        // 事件订阅
        useUnoEvent('customEvent', (data) => {
            console.log('Received event:', data);
        });

        // 方法创建
        useUnoMethod('customMethod', (param) => {
            console.log('Method called with:', param);
            return 'response';
        });

        return { uno, params, globals };
    },
};

显式导入 React 模块

import { useUno, useUnoParams, useUnoGlobals } from '@genee/uno-webview/react';

父端 WebView(宿主页)

import { WebView } from '@genee/uno-webview/parent';

<WebView
    src="https://app.example.com/embed"
    params={{ token: 'xxx' }}
    // 只接受这些来源的子端;不传则不限制(targetOrigin 回落为 '*')
    targetOrigins={['https://app.example.com']}
/>;

配置了 targetOrigins 后,来源不在白名单内的 iframe 不会被握手、收不到任何消息,父端也不会响应它发起的 getParams 等方法调用。来源以浏览器填写的 event.origin 为准(不可伪造),命中的来源会被用作后续 postMessage 的 targetOrigin。

API 参考

核心函数

useUno() / getUno()

获取 Uno 实例,用于与父窗口通信。

useUnoParams(keys?: string[])

获取响应式参数。

  • React: 返回 Record<string, any> 或 any[]
  • Vue: 返回 Ref<Record<string, any>> 或 Ref<any[]>

useUnoGlobals(keys?: string[])

获取响应式全局状态。

  • React: 返回 Record<string, any> 或 any[]
  • Vue: 返回 Ref<Record<string, any>> 或 Ref<any[]>

useUnoEvent(event: string, handler: Function)

订阅事件,组件卸载时自动取消订阅。

useUnoMethod(method: string, handler: Function)

创建方法,组件卸载时自动销毁。

父端组件

<WebView />

| 属性 | 类型 | 说明 | | --- | --- | --- | | params | any | 下发给当前子端实例的参数(必填) | | targetOrigins | string[] | 可信子端来源白名单;留空则不做校验 | | logger | CommonLogger | 日志实现,默认 console | | sessionStorage | { getItem, setItem } | 子端 Session.* 的落地方 | | onLocationChange | (uri: string) => void | 子端 updateCurrentLocation 回调 | | onMethod | (method, params) => any | 兜底处理子端发起的任意方法调用 | | onReady | (rpc: ContentWindowRPC) => void | 每次握手完成时回调当前 rpc 实例 |

类型支持

本库提供完整的 TypeScript 类型定义,支持 React 和 Vue 3 的类型推断。

兼容性

  • React 18+
  • Vue 3.0+
  • TypeScript 4.5+
