如何找到冲突的 eslint 规则

Question

在规则中查找冲突的最佳方法是什么？

我要解决的问题如下。有些东西迫使这个三元表达式换行。我怀疑这与长线有关，但我尝试设置 max-len 没有任何变化：

setAdjustmentValue((props.adjustmenttype === AdjustmentTypes.Restock) ? props.selectedsiteunitstock.maximumCapacity - props.selectedsiteunitstock.currentStockLevel : null);

检查到：

setAdjustmentValue(
            props.adjustmenttype === AdjustmentTypes.Restock
                ? props.selectedsiteunitstock.maximumCapacity -
                        props.selectedsiteunitstock.currentStockLevel
                : null
        );

如果我设置 "multiline-ternary": ["error", "never"]

，lint 会失败

这是我的完整配置：

    }
}

Answer 1

我创建了一个非常简单的项目来进行测试。我非常基本的 .eslintrc 配置文件只包含一个规则 quotes:

{
    "parserOptions": {
        "ecmaVersion": 6,
        "sourceType": "script"
    },
    "rules": {
        "quotes": ["error", "double"]
    }
}

还有我要测试的index.js文件：

let no = 'this is wrong';

let yes = "this is correct bc i enforced double quotes";

现在，运行以下命令：

npx eslint index.js

产生以下输出：

2:10 error Strings must use doublequote quotes

其中“字符串必须使用双引号”后的引号是引发错误的规则。

而在 VSCode 中它看起来像这样：

2022 年读者使用

"eslint-config-airbnb": "^19.0.4",
"eslint-config-airbnb-typescript": "^16.1.4",

您需要将此添加到您的 eslintrc(.json):

"@typescript-eslint/semi": ["error", "never"],

在我的用例中，我不想看到任何 fu#king semi。
