micro-app is a micro front-end framework launched by JD Retail. It renders based on webcomponent-like and realizes the micro front-end from component thinking, it aiming to reduce the difficulty of getting started and improve work efficiency.

It is the lowest cost framework for accessing micro front-end, and provides a series of perfect functions such as JS sandbox, style isolation, element isolation, preloading, resource address completion, plugin system, data communication and so on.

micro-app has no restrictions on the front-end framework, and any framework can be used as a base application to embed any type of micro application of the framework.

The micro front end is divided into a base application (also called main application) and a micro application.

Here is a common example: the base application uses the Vue framework, uses history routing, the micro application uses the react framework, and uses hash routing. We list the modifications that need to be made by the base application and the micro application, and introduce the use of micro-app in detail.

1、Install

yarn add @micro-zoe/micro-app

2、import at the entrance

// main.js
import microApp from '@micro-zoe/micro-app'

microApp.start()

3、Use components in page

<!-- my-page.vue -->
<template>
  <!-- 👇 name is the app name, url is the app address -->
  <micro-app name='my-app' url='https://localhost:3000/'></micro-app>
</template>

Set cross-domain support in the headers of webpack-dev-server

devServer: {
  headers: {
    'Access-Control-Allow-Origin': '*',
  },
},

The above micro front-end rendering is completed, and the effect is as follows:
