reactjs中如何导出复合组件

Question

I am trying to get my hands on compound component pattern in ReactJS. And all is good but I am not able to export the component the way I want.

I have created one basic Table (Data Grid), which has many component like header, row, column, search, pagination etc.

And I want the end user to import this Table in this way.

import Table from './Table'

const DataGrid = () => {
     return (
        <Table>
            <Table.Title></Table.Title>
            <Table.Header>
                <Table.Row></Table.Row>
            </Table.Header>
        
            <Table.Body>
                <Table.Row></Table.Row>
            </Table.Body>
        </Table>
     )
}

Now in component folder, I have one index.js file where I am trying to import all component and then trying to export it in a object

import {Table} from './Table'
import {Title} from './Title'
import {Header} from './Header'
import {Body} from './Body'

Now what should I do to export in a way I want. Tried many solutions, but nothing is working.

Answer 1

You need to import everything in index file and prepare a new object and export it:

index.js:

import { Table } from "./Table"; // this imports from Table.jsx file
import { Title } from "./Title";
import { Body } from "./Body";
import { Header } from "./Header";
import { Row } from "./Row";

const all = Table; // <-- Here: this (all) is the new object.
// We can name it whatever we want as it is going to be a default export

all.Title = Title;
all.Body = Body;
all.Header = Header;
all.Row = Row;

export default all;

Now, you can use it like shown below:

DataGrid.jsx:

import Table from "./Table"; // this imports from index.js file under "Table" folder

const DataGrid = () => {
  return (
    <Table>
      <Table.Title></Table.Title>
      <Table.Header>
        <Table.Row></Table.Row>
      </Table.Header>

      <Table.Body>
        <Table.Row></Table.Row>
      </Table.Body>
    </Table>
  );
};

Edit:

This answer assumes that you have components under directories like below. Make sure to change the paths when importing if you have a different one.

src/
  Table/
    Body.jsx
    Header.jsx
    index.js
    Row.jsx
    Table.jsx
    Title.jsx
  DataGrid.jsx
