umi官方推荐结合dva使用更配哦,其实他们都是同一位开发者开发的,属于阿里内部开源框架。
1 修改.umirc.js
,开启dva支持
// ref: https://umijs.org/config/
export default {
plugins: [
// ref: https://umijs.org/plugin/umi-plugin-react.html
['umi-plugin-react', {
antd: true,
dva: true,
dva: {
immer: true
},
dynamicImport: false,
title: 'umis',
dll: false,
hardSource: false,
routes: {
exclude: [
/components\//,
],
},
}],
],
}
2 修改layouts
先搞一个后台的布局,可以参考ANT DESIGN PRO
https://pro.ant.design/layouts\index.js
import styles from './index.less';
import { Layout, Menu, Breadcrumb, Icon } from 'antd';
import { Component } from 'react';
import Link from 'umi/link';
import logo from '../assets/logo.svg';
const {Header, Content, Footer, Sider} = Layout;
const SubMenu = Menu.SubMenu;
class BasicLayout extends Component {
constructor(props) {
super(props);
this.state = {
collapsed: false,
};
}
toggle = () => {
this.setState({
collapsed: !this.state.collapsed,
});
}
render(){
return (
Ant Design Pro
{/*此处可加面包屑*/}
{ this.props.children }
);
}
}
export default BasicLayout;
layouts\index.less
.logo {
height: 64px;
position: relative;
line-height: 64px;
transition: all 0.3s;
background: #002140;
overflow: hidden;
img {
display: inline-block;
vertical-align: middle;
height: 32px;
}
h1 {
color: white;
display: inline-block;
vertical-align: middle;
font-size: 20px;
margin: 0 0 0 12px;
font-family: 'Myriad Pro', 'Helvetica Neue', Arial, Helvetica, sans-serif;
font-weight: 600;
}
}
.trigger {
font-size: 18px;
line-height: 64px;
padding: 0 24px;
cursor: pointer;
transition: color .3s;
.logo {
height: 32px;
background: rgba(255,255,255,.2);
margin: 16px;
}
}
.sider {
min-height: 100vh;
box-shadow: 2px 0 6px rgba(0, 21, 41, 0.35);
position: relative;
z-index: 10;
&.ligth {
background-color: white;
.logo {
background: white;
h1 {
color: #002140;
}
}
}
}
3 改造users页面,完成dva整个流程。
- 在pages下创建users目录
- 创建index.js 会生成默认路由http://localhost:8000/users
import { connect } from 'dva';
import { Table, Pagination, Popconfirm } from 'antd';
import styles from './users.css';
const PAGE_SIZE = 5;
function Users({ list: dataSource, total, page: current }) {
function deleteHandler(id) {
console.warn(`TODO: ${id}`);
}
const columns = [
{
title: 'Name',
dataIndex: 'name',
key: 'name',
render: text => {text},
},
{
title: 'Email',
dataIndex: 'email',
key: 'email',
},
{
title: 'Website',
dataIndex: 'website',
key: 'website',
},
{
title: 'Operation',
key: 'operation',
render: (text, { id }) => (
Edit
Delete
),
},
];
return (
record.id}
pagination={false}
/>
);
}
function mapStateToProps(state) {
const { list, total, page } = state.users;
console.log(state.test);
return {
list,
total,
page,
};
}
export default connect(mapStateToProps)(Users);
- 创建对应的model.js,因为只有一个model所以不需要创建models目录。但是名字必须为model.js,不然不能自动注册。
//只有一个model的话,可以不用建models目录。但名字必须为model。js
import * as usersService from './service';
export default {
namespace: 'users',
state: {
list: [],
total: null,
},
reducers: {
save(state, { payload: { data: list, total } }) {
return { ...state, list, total };
},
},
effects: {
*fetch({ payload: { page } }, { call, put }) {
const { data} = yield call(usersService.fetch, { page });
yield put({ type: 'save', payload: { data, total: data.length } });
},
},
subscriptions: {
setup({ dispatch, history }) {
return history.listen(({ pathname, query }) => {
if (pathname === '/users') {
dispatch({ type: 'fetch', payload: query });
}
});
},
},
};
- 创建service.js 这个不需要约定名称,你随便起名字
import request from '../../utils/request';
export function fetch({ page = 1 }) {
return request(`/api/users?_page=${page}&_limit=5`);
}
- 创建utils目录,封装统一请求api
utils\request.js
import fetch from 'dva/fetch';
function checkStatus(response) {
if (response.status >= 200 && response.status < 300) {
return response;
}
const error = new Error(response.statusText);
error.response = response;
throw error;
}
/**
* Requests a URL, returning a promise.
*
* @param {string} url The URL we want to request
* @param {object} [options] The options we want to pass to "fetch"
* @return {object} An object containing either "data" or "err"
*/
export default async function request(url, options) {
const response = await fetch(url, options);
checkStatus(response);
const data = await response.json();
const ret = {
data
};
return ret;
}
- 创建mock假数据
mock\user.js
export default {

4 总结
- 按umi推荐的方式去创建目录
- 注意约定名 pages目录下的所有js都回被默认生成路由,可通过配置排出
- 省略了model的手动注册,至于忽略
namespace
,我试了不行
- 各个page的model不能相互引用?不是很明白什么意思,我试了每个page都能获取所有的state,并不是只能获取属于自己的。可能是我理解有误。
- 没有看出来umi的好处,只是目录的区别吗?
这个 issues 下有关于umi按page分的讨论。https://github.com/sorrycc/bl...
希望知道umi核心优势的小伙伴留言解释下,前端菜鸟不是很懂。
