Functional ComponentでもReact RouterのwithRouterを使う方法

Posted at

React RouterのwithRouterを、Class ComponentではなくFunctional Componentで使用する方法についてまとめます。

環境

  • react v16.10.1
  • react-router-dom v5.1.2

結論

  1. コンポーネント全体をwithRouterでラップし、引数としてpropsを渡す
  2. props.history.push("url")で遷移する
import React from 'react';
import { withRouter } from 'react-router-dom'

// コンポーネント全体をwithRouterでラップする
export const MyComponent = withRouter(props => {

    function handlePageMove() {
            // 遷移先のパスを設定
            props.history.push("/Home");
    }

    return (
        <>
            <button
                onClick={handlePageMove}
            >Go to Home!</button>
        </>
    );
});

補足

  • 親コンポーネントがある場合でも、子コンポーネントだけラップしたらOK
import React from 'react';
import { withRouter } from 'react-router-dom'

const MyComponent = withRouter(props => {
    // 上記と同じ
});

// 親コンポーネントはwithRouterでのラップは不要
export const ParentComponent = _ => {
    return (
        <>
            <MyComponent />
        </>
    );
}
