Ant Design Landing-阿里云开发者社区

最近在做一些SAAS产品，Landing page——落地页对于SAAS类产品的重要性不言而喻。之前有想过用wordpress找一些比较漂亮的模板，但想想觉得这个方案对于初期的产品来说还是有点重了。用Vue的话，找了一圈没有发现合适的模板。React体系内，我发现Ant Design生态里有一款Ant Design Landing 框架，简洁明了，又不失美观，比较符合我的需求。

我们来初步看看怎么使用 Ant Design Landing。

我们直接在create-react-app里使用 Ant Design Landing 的模板，create-react-app 是业界最优秀的 React 应用开发工具之一，也可以直接下载官方给出的Demo:anding-create-react-app-example。

安装与初始化

create-react-app的安装和初始化：

npm init react-app my-app

安装完成后，目录结构:

├── README.md
├── node_modules
├── package.json
├── .gitignore
├── public
│   ├── favicon.ico
│   ├── index.html
│   └── manifest.json
│── src
│   ├── App.css
│   ├── App.js
│   ├── App.test.js
│   ├── index.css
│   ├── index.js
│   ├── logo.svg
│   └── serviceWorker.js

文件路径

我们直接将从 Landing 上下载的 Home 文件夹直接拷贝到 src 文件包里;

├── README.md
├── ...
├── public
│   ├── ...
│── src
+   ├── Home
+   │   ├── less
+   │   ├── index.js
+   │   ├── ...
│   ├── App.css
│   ├── App.js
│   ├── App.test.js
│   ├── index.css
│   ├── index.js
│   ├── logo.svg
│   └── serviceWorker.js

安装依赖

基础必要组件依赖：

npm install antd enquire-js rc-queue-anim rc-scroll-anim rc-tween-one --save;
npm install rc-banner-anim --save;// 如果用的是多屏滑动型的 banner，加上这条;
npm install @ant-design/compatible --save;// 如果使用了 Content7 模块，请加上这条;

按需加载ant design

npm install babel-plugin-import --save-dev;

less加载：

npm install react-app-rewired customize-cra less less-loader

配置加载less

安装完 less 加载 后，我们还需要修改 package.json 里的启动配置。

/* package.json */
"scripts": {
-   "start": "react-scripts start",
+   "start": "react-app-rewired start",
-   "build": "react-scripts build",
+   "build": "react-app-rewired build",
-   "test": "react-scripts test",
+   "test": "react-app-rewired test",
}

创建config-overrides.js

然后在项目根目录创建一个 config-overrides.js 用于修改默认配置。

├── README.md
├── node_modules
├── package.json
├── .gitignore
+── config-overrides.js
├── public
│   ├── ...
│── src
│   ├── Home
│   └── ...

config-overrides.js

const { override, fixBabelImports, addLessLoader } = require('customize-cra');
module.exports = override(
// 按需加载 antd
fixBabelImports('import', {
  libraryName: 'antd',
  libraryDirectory: 'es',
  style: true,
}),
// 添加加载 less 的 javascriptEnabled 和 antd 的主题配置。
addLessLoader({
  lessOptions: {
    javascriptEnabled: true,
    modifyVars: { '@primary-color': '#1DA57A' },
  }
}),
);

修改入口文件

更改的 src 里的 index.js 页面，打开 index.js，引入 Home 文件包并渲染。

src/index.js

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
- import App from './App';
+ import App from './Home';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: http://bit.ly/CRA-PWA
serviceWorker.unregister();

启动

完成以上步骤后执行 npm install, 再 npm start即可查看下载的模板。

npm install
npm start

遇到的问题

其中遇到了一个 Module not found: Can't resolve './serviceWorker' in ../MyApp\src 的错误

仔细查看后是 serviceWorker.js 没有下载下来，直接将serviceWorker.js复制到src目录下即可

// This optional code is used to register a service worker.
// register() is not called by default.
// This lets the app load faster on subsequent visits in production, and gives
// it offline capabilities. However, it also means that developers (and users)
// will only see deployed updates on subsequent visits to a page, after all the
// existing tabs open on the page have been closed, since previously cached
// resources are updated in the background.
// To learn more about the benefits of this model and instructions on how to
// opt-in, read http://bit.ly/CRA-PWA
const isLocalhost = Boolean(
window.location.hostname === 'localhost' ||
  // [::1] is the IPv6 localhost address.
  window.location.hostname === '[::1]' ||
  // 127.0.0.1/8 is considered localhost for IPv4.
  window.location.hostname.match(
    /^127(?:\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){3}$/
  )
);
export function register(config) {
if (process.env.NODE_ENV === 'production' && 'serviceWorker' in navigator) {
  // The URL constructor is available in all browsers that support SW.
  const publicUrl = new URL(process.env.PUBLIC_URL, window.location.href);
  if (publicUrl.origin !== window.location.origin) {
    // Our service worker won't work if PUBLIC_URL is on a different origin
    // from what our page is served on. This might happen if a CDN is used to
    // serve assets; see https://github.com/facebook/create-react-app/issues/2374
    return;
  }
  window.addEventListener('load', () => {
    const swUrl = `${process.env.PUBLIC_URL}/service-worker.js`;
    if (isLocalhost) {
      // This is running on localhost. Let's check if a service worker still exists or not.
      checkValidServiceWorker(swUrl, config);
      // Add some additional logging to localhost, pointing developers to the
      // service worker/PWA documentation.
      navigator.serviceWorker.ready.then(() => {
        console.log(
          'This web app is being served cache-first by a service ' +
            'worker. To learn more, visit http://bit.ly/CRA-PWA'
        );
      });
    } else {
      // Is not localhost. Just register service worker
      registerValidSW(swUrl, config);
    }
  });

      }

        if (installingWorker.state === 'installed') {
          if (navigator.serviceWorker.controller) {
            // At this point, the updated precached content has been fetched,
            // but the previous service worker will still serve the older
            // content until all client tabs are closed.
            console.log(
              'New content is available and will be used when all ' +
                'tabs for this page are closed. See http://bit.ly/CRA-PWA.'
            );
            // Execute callback
            if (config && config.onUpdate) {

          } else {
            // At this point, everything has been precached.
            // It's the perfect time to display a
            // "Content is cached for offline use." message.
            console.log('Content is cached for offline use.');
            // Execute callback
            if (config && config.onSuccess) {
              config.onSuccess(registration);
            }
          }
        }
      };
    };
  })
  .catch(error => {
    console.error('Error during service worker registration:', error);
  });
}
function checkValidServiceWorker(swUrl, config) {
// Check if the service worker can be found. If it can't reload the page.
fetch(swUrl)
  .then(response => {
    // Ensure service worker exists, and that we really are getting a JS file.
    const contentType = response.headers.get('content-type');
    if (
      response.status === 404 ||
      (contentType != null && contentType.indexOf('javascript') === -1)
    ) {
      // No service worker found. Probably a different app. Reload the page.
      navigator.serviceWorker.ready.then(registration => {

          window.location.reload();
        });
