Ant Design Landing

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
复制代码


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
复制代码

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
复制代码

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;
复制代码

按需加载 ant design

npm install babel-plugin-import --save-dev;
复制代码

less 加载:

npm install react-app-rewired customize-cra less less-loader
复制代码

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",}
复制代码

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│   └── ...
复制代码

config-overrides.js

const { override, fixBabelImports, addLessLoader } = require('customize-cra');
module.exports = override(// 按需加载 antdfixBabelImports('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' }, }}),);
复制代码

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-PWAserviceWorker.unregister();
复制代码

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
复制代码


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); } });}}
function registerValidSW(swUrl, config) {navigator.serviceWorker .register(swUrl) .then(registration => { registration.onupdatefound = () => { const installingWorker = registration.installing; if (installingWorker == null) { return; } installingWorker.onstatechange = () => { 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) { config.onUpdate(registration); } } 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 => { registration.unregister().then(() => { window.location.reload(); }); }); } else { // Service worker found. Proceed as normal. registerValidSW(swUrl, config); } }) .catch(() => { console.log( 'No internet connection found. App is running in offline mode.' ); });}
export function unregister() {if ('serviceWorker' in navigator) { navigator.serviceWorker.ready.then(registration => { registration.unregister(); });}}
