规则 | Rules

no-restricted-properties

对象上的某些属性可能在代码库中被禁止。这对于取消API或限制模块方法的使用很有用。例如,您可能希望使用不允许describe.only使用摩卡或者告诉人们使用时Object.assign代替_.extend

规则细节

此规则查找在给定对象名称上访问给定属性键时,可以在读取属性值或将其作为函数调用时使用。您可以指定一个可选消息来指示替代API或限制原因。

选项

此规则接受一个对象列表,其中指定了对象名称和属性名称:

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

多个对象/属性值可以被禁止,并且您可以指定一个可选消息:

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

如果省略对象名称,则不允许所有对象的属性:

{
    "rules": {
        "no-restricted-properties": [2, {
            "property": "__defineGetter__",
            "message": "Please use Object.defineProperty instead."
        }]
    }
}

如果省略属性名称,则不允许访问给定对象的任何属性:

{
    "rules": {
        "no-restricted-properties": [2, {
            "object": "require",
            "message": "Please call require() directly."
        }]
    }
}

此规则的错误代码示例:

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

var example = disallowedObjectName.disallowedPropertyName; /*error Disallowed object property: disallowedObjectName.disallowedPropertyName.*/

disallowedObjectName.disallowedPropertyName(); /*error Disallowed object property: disallowedObjectName.disallowedPropertyName.*/
/* eslint no-restricted-properties: [2, {
    "property": "__defineGetter__"
}] */

foo.__defineGetter__(bar, baz);
/* eslint no-restricted-properties: [2, {
    "object": "require"
}] */

require.resolve('foo');

此规则的正确代码示例:

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

var example = disallowedObjectName.somePropertyName;

allowedObjectName.disallowedPropertyName();
/* eslint no-restricted-properties: [2, {
    "object": "require"
}] */

require('foo');

何时不使用它

如果您没有要限制的任何对象/属性组合,则不应使用此规则。

Eslint

ESLint 是一个代码规范和错误检查工具,有以下几个特性。所有东西都是可以插拔的。你可以调用任意的 rule api 或者 formatter api 去打包或者定义 rule or formatter。任意的 rule 都是独立的。没有特定的 coding style,你可以自己配置。
