Real project with umi and dva

In real project development, you might need a data flow solution like Redux or MobX. Ant Design React is a UI library that can be used with any data flow solution and application framework within the React ecosystem. We have launched dva based on Redux, as well as a pluggable enterprise application framework umi, which is recommended for use in your projects.

Dva is a lightweight data flow solution based on Redux. The concept comes from elm. It supports side effects, hot module replacement, dynamic loading, react-native, SSR, etc. It has been widely used in production.

And umi is a routing-based framework that supports next.js-like conventional routing and various advanced routing functions, such as routing-level on-demand loading. With a complete plugin system that covers every life cycle from source code to build product, umi is able to support various functional extensions and business needs; meanwhile Umi UI is provided to enhance the development experience and development efficiency through Visual Aided Programming (VAP).

This article will guide you to create a simple application from zero using Umi UI, dva and antd.

Install Umi UI#

It is recommended to use yarn to create an application and execute the following command.

If you are using npm, execute npm install umi -g and the effect will be the same.

$ yarn global add umi
$ umi -v

Make sure the umi version is above 2.10.0.

Create New App#

Start the app,

$ umi ui

🚀 Starting Umi UI using [email protected]...
🧨  Ready on http://localhost:3000/

After starting, Umi UI will automatically open the browser, then click Create Project, select the path and enter App name, as shown below.

Click Next, select Basic Template, select antd and dva on the technology stack, then click Finish.

In the project creation process, wait a few minutes.

After creating, go to Overview and click on the shortcut entry Run Dev.

In the task page, click Start,

When prompted, open http://localhost:8000 in your browser, you will see the welcome page of umi.

Integrate antd#

After selecting antd earlier, antd's dependencies are automatically handled and loaded on demand. You can check the Configuration to make sure antd is turned on.

And if you want to use a fixed version of antd, you can install additional antd dependency in your project, and the antd dependencies declared in package.json will be used first.

Create Routes#

We need to write an application displaying the list of products. The first step is to create a route.

If you don't have npx, you need to install it first to execute the commands under node_modules.

$ yarn global add npx

Then create a /products route,

$ npx umi g page products

   create src/pages/products.js
   create src/pages/products.css
✔  success

Then open http://localhost:8000/products in your browser and you should see the corresponding page.

Write UI Components#

As your application grows and you notice you are sharing UI elements between multiple pages (or using them multiple times on the same page), in umi it's called reusable components.

Let's create a ProductList component that we can use in multiple places to show a list of products.

Click Open in editor,

Create src/components/ProductList.js by typing:

import { Table, Popconfirm, Button } from 'antd';

const ProductList = ({ onDelete, products }) => {
  const columns = [
      title: 'Name',
      dataIndex: 'name',
      title: 'Actions',
      render: (text, record) => {
        return (
          <Popconfirm title="Delete?" onConfirm={() => onDelete(}>
  return <Table dataSource={products} columns={columns} />;

export default ProductList;

Define dva Model#

After completing the UI, we will begin processing the data and logic.

dva manages the domain model with model, with reducers for synchronous state updates, effects for async logic, and subscriptions for data source subscribe.

Let's create a model src/models/products.js by typing,

export default {
  namespace: 'products',
  state: [],
  reducers: {
    delete(state, { payload: id }) {
      return state.filter(item => !== id);

In this model:

  • namespace represents the key on global state

  • state is the initial value, here it is an empty array

  • reducers is equivalent to a reducer in redux, accepting an action, and update state simultaneously

In umi, the model files under src/models will be automatically injected, you don't need to inject manually.


So far, we have completed a separate model and component. How do we connect them together?

dva provides a connect method. If you are familiar with redux, this connect is from react-redux.

Edit src/pages/products.js and replace it with the following,

import { connect } from 'dva';
import ProductList from '../components/ProductList';

const Products = ({ dispatch, products }) => {
  function handleDelete(id) {
      type: 'products/delete',
      payload: id,
  return (
      <h2>List of Products</h2>
      <ProductList onDelete={handleDelete} products={products} />

export default connect(({ products }) => ({

Finally, we need some initial data to make the application run together. Edit src/app.js,

export const dva = {
  config: {
    onError(err) {
    initialState: {
      products: [{ name: 'dva', id: 1 }, { name: 'antd', id: 2 }],

Refresh your browser, you should see the following result:


Now that we've written our application and verified that it works in development, it's time to get it ready for deployment to our users. To do so, click build in Task page.

The build command packages up all of the assets that make up your application —— JavaScript, templates, CSS, web fonts, images, and more. Then you can find these files in the dist/ directory.

What's Next#

We have completed a simple application, but you may still have lots of questions, such as:

  • How to handle onError globally and locally?

  • How to handle routes?

  • How to mock data?

  • How to deploy?

  • ant so on...
