根据输入动态导入 React 组件

Question

I want to render different Components based on some checkboxes selection pattern without having to import components that may not be used.

I have an Array which contains the Component names (I used numbers as an example) and I want to import each component based on the values of the array.

I came up with something like this:

import {Suspense} from 'react'


export default function CreationForm() {

 const docs = [1,3,5]

  return (
      <Suspense fallback={<div>Loading...</div>}>
        {
          docs.map(val => React.lazy(() => import(`documents/${val}.jsx`)))   
        }
      </Suspense>
  )

}

I know this solution does not work but I think it explains what I am trying to do.

I could try using state but the actual "docs array" is an state variable in the real application so it could cause duplicated state.

I did this as a test and worked:

  const A = React.lazy(() => import(`documents/1.jsx`))
  ...
  *** SNIP ***
  ...
      <Suspense fallback={<div>Loading...</div>}>
        {
          docs.map((val) => <A/>)   
        }
      </Suspense>

But I cannot dynamically import each component like this.

Ok, so you don't need conditional imports, you just want to do conditional rendering. That's waaaaay simpler.

Example:

import { FormA } from "./FormA";
import { FormB } from "./FormB";

const MyComponent = ({ which }) => {
    return <>
        {which === "form-a" && <FormA />}
        {which === "form-b" && <FormB />}
    <>;
};
