スプレッド演算子とEsLint

Question

オブジェクトをコピーしてそのフィールドの1つを変更したいとします。このような何か：

const initialState = { 
    showTagPanel: false, 
}; 

export default function reducerFoo(state = initialState, action) { 

    switch(action.type) { 
    case types.SHOW_TAG_PANEL: 
     console.log(state); 

     return { 
     ...state, 
     showTagPanel: true 
     }; 

    default: 
     return state; 
    } 
} 

このコードは正常に動作しますが、eslintは私が

Unexpected token (14:8) 
    12 | 
    13 |  return { 
> 14 |   ...state, 
    |  ^
    15 |   showTagPanel: true 
    16 |  }; 
    17 | 

ここ

私.eslintrcされたエラーを示しています。

は、私はそれをどのように修正することができますか？

Answer 1

.eslintrcファイルにexperimentalObjectRestSpread: true〜ecmaFeaturesを追加してください。

例

{ 
    "extends": [ 
    "eslint:recommended" 
    ], 
    "parserOptions": { 
    "ecmaVersion": 6, 
    "sourceType": "module", 
    "ecmaFeatures": { 
     "jsx": true, 
     "experimentalObjectRestSpread": true 
    } 
}
