no-restricted-properties

禁止某些对象的某些属性

代码库中可能不允许对象的某些属性。这对于弃用 API 或限制模块方法的使用很有用。例如，您可能希望在使用 Mocha 时禁止使用 describe.only，或者告诉人们使用 Object.assign 而不是 _.extend。

规则详情

此规则查找访问给定对象名称上的给定属性键，无论是在读取属性值还是将其作为函数调用时。您可以指定可选消息来指示替代 API 或限制原因。

选项

此规则采用对象列表，其中指定了对象名称和属性名称：

{
    "rules": {
        "no-restricted-properties": [2, {
            "object": "disallowedObjectName",
            "property": "disallowedPropertyName"
        }]
    }
}

可以禁止多个对象/属性值，您可以指定可选消息：

{
    "rules": {
        "no-restricted-properties": [2, {
            "object": "disallowedObjectName",
            "property": "disallowedPropertyName"
        }, {
            "object": "disallowedObjectName",
            "property": "anotherDisallowedPropertyName",
            "message": "Please use allowedObjectName.allowedPropertyName."
        }]
    }
}
