Contemporary web applications are becoming increasingly complex, and with it comes an increase in application complexity and maintenance difficulty. Micro frontend architecture is a new architectural pattern that solves these problems by decomposing the application into small and independent parts, thus enabling developers to independently develop, test and deploy different parts of the application. Microapp is a micro-frontend framework that provides a simple way to implement a micro-frontend architecture. This article will introduce how to get started with Microapp.
What are Microapps?
Microapp is a micro frontend framework based on Web Components. It allows developers to break down applications into small, independent components and assemble them together in a plug-in-like fashion. This means that developers can independently develop, test and deploy each component, which improves the maintainability and scalability of the application.
The core idea of Microapp is to decompose an application into small, independent components, each with its own state and functionality. These components can be developed using their own technology stack and tools, such as React, Vue or Angular, etc. Then, these components can be assembled together through some common interfaces to form a complete application.
How to get started with Microapp?
To start using Microapp, you first need to install the Microapp CLI tool. It can be installed with the following command:
Copy
npm install -g @microapp/cli
After the installation is complete, you can use the Microapp CLI to create a new Microapp project, for example:
Copy
microapp create my-app
This will create a new project called "my-app" with some default configuration and sample code in it. Then, the project can be started with:
Copy
cd my-app
npm start
This will start a development server locally, you can visit http://localhost:3000 in your browser to view your Microapp project.
How to create Microapp?
To create a new Microapp, you can use the commands provided by the Microapp CLI to create a new component, for example:
dsconfig
Copy
microapp create-component my-component
This will create a new component called "my-component" with some default configuration and sample code in it. The component can then be started with the following command:
Copy
cd my-component
npm start
This will start a development server locally, and you can view the component by visiting http://localhost:3000 in your browser.
How to compose Microapp components together?
To compose Microapp components together, you can use the API provided by Microapp to register and load components. For example, the following code snippet demonstrates how to register and load a Microapp component called "my-component":
javascript
Copy
import { registerComponent, loadComponent } from ‘@microapp/core’;
registerComponent(‘my-component’, ‘http://localhost:3001/my-component.js’);
loadComponent('my-component').then(() => { console.log('my-component is loaded!'); }); In the code snippet above, we first use the registerComponent() method to register a A component named "my-component" and specify its URL. Then, we use the loadComponent() method to load the component, and once loaded, the callback function is executed and prints "my-component is loaded!".
Summary
Microapp is a micro-frontend framework based on Web Components, which provides an easy way to implement a micro-frontend architecture. By decomposing an application into small, independent components and assembling them together in a plug-in-like fashion, developers can independently develop, test, and deploy different parts of an application. In this article, we covered how to get started with Microapps, create Microapp components, and put them together.
