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：
代码语言：javascript复制npm init react-app my-app安装完成后，目录结构:
代码语言：javascript复制├── 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：
代码语言：javascript复制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
代码语言：javascript复制npm install babel-plugin-import --save-dev;less加载：
代码语言：javascript复制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
代码语言：javascript复制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
代码语言：javascript复制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。
代码语言：javascript复制npm install
npm start
遇到的问题
其中遇到了一个 Module not found: Can't resolve './serviceWorker' in ../MyAppsrc 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
代码语言：javascript复制// 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]' ||

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;

// "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 => {

}
function checkValidServiceWorker(swUrl, config) {

navigator.serviceWorker.ready.then(registration => {

export function unregister() {
