What are the commands to write when using React components to transfer Vue components?

This article first introduces the commonalities and incompatibilities between the components of the two frameworks, and then introduces the use and principles of react-to-vue. Friends in need can refer to it

Based on the current popularity of React and Vue, The purpose of developing the react-to-vue tool is to further improve the reusability of components, so that component reuse is not limited to just one framework

Introduction

For the react-to-vue tool, the basic react component is converted, not the entire react application. The definition of basic react component is more of a component that is rendered based on props and state, which can also include making requests.

This article first introduces the commonalities and incompatibilities between the components of the two frameworks, and then introduces the use and principles of react-to-vue. In actual business, more than 90% of Lufax's react-to-vue basic business components can be converted into Vue components.

Inventory of common components of the two frameworks

1. props

// react
FrontendMagazine.propTypes = {
  name: PropTypes.string
}
FrontendMagazine.defaultProps = {
  name: 'FrontendMagazine'
}
// vue
{
  name: 'frontend-magazine',
  props: {
    name: {
      type: String,
      default: 'FrontendMagazine'
    }
  }
}

2. Component’s own state

#3. Life cycle

Although the life cycle names are different, they are almost the same. Corresponding

4. Processing events

// react
class FrontendMagazine {
  clickme () {
    // xxxx
  }
}
// vue
{
  name: 'frontend-magazine',
  methods: {
    clickme () {
      // xxx
    }
  }
}

5. Component Error catching

react is written based on jsx. For vue, although it can be written using template in many scenarios, vue also fully supports jsx syntax. For this tool, it only uses the jsx syntax of react. Convert to jsx supported by vue

In the latest version of react, there is support for flags, allowing the root node to return multiple nodes. At present, I have not seen any support for vue. Also, when designing react components, I used high-level ones, which is not supported by this tool.

Installation and use

# install
npm install -g react-to-vue
# usage
Usage: rtv [options] file(react component)

Options:

 -V, --version     output the version number
 -o --output [string] the output file name
 -t --ts        it is a typescript component
 -h, --help      output usage information

# demo

rtv demo.js

Principle steps

First use babylon to parse the input file and generate ast
If the file is typescript, the corresponding ts description
Traverse ast, first extract propTypes and defaultProps

3. ##According to the component type, process function components and class components

4. In the class component, the life cycle, state and other information need to be converted

5. Finally, based on the extracted information, it is spliced ​​into a vue component and used through prettier-eslint Beautification
Comparison before and after conversion
