no-restricted-exports

禁止在导出中指定名称

在项目中，出于各种原因，某些名称可能不允许用作导出名称。

规则详情

此规则不允许将指定名称用作导出名称。

选项

默认情况下，此规则不允许任何名称。只有您在配置中指定的名称才会被禁止。

此规则有一个对象选项：

• "restrictedNamedExports" 是一个字符串数组，其中每个字符串是一个要限制的名称。

此规则的错误代码示例：

/*eslint no-restricted-exports: ["error", {
    "restrictedNamedExports": ["foo", "bar", "Baz", "a", "b", "c", "d", "e", "👍"]
}]*/

export const foo = 1;

export function bar() {}

export class Baz {}

const a = {};
export { a };

function someFunction() {}
export { someFunction as b };

export { c } from "some_module";

export { "d" } from "some_module";

export { something as e } from "some_module";

export { "👍" } from "some_module";

此规则的正确代码示例：

/*eslint no-restricted-exports: ["error", {
    "restrictedNamedExports": ["foo", "bar", "Baz", "a", "b", "c", "d", "e", "👍"]
}]*/

export const quux = 1;

export function myFunction() {}

export class MyClass {}

const a = {};
export { a as myObject };

function someFunction() {}
export { someFunction };

export { c as someName } from "some_module";

export { "d" as " d " } from "some_module";

export { something } from "some_module";

export { "👍" as thumbsUp } from "some_module";

默认导出

按照设计，此规则不允许 export default 声明。如果将 "default" 配置为受限名称，则该限制将仅适用于命名的导出声明。

此规则的其他错误代码示例：

/*eslint no-restricted-exports: ["error", { "restrictedNamedExports": ["default"] }]*/

function foo() {}

export { foo as default };

/*eslint no-restricted-exports: ["error", { "restrictedNamedExports": ["default"] }]*/

export { default } from "some_module";

此规则的附加正确代码示例：

/*eslint no-restricted-exports: ["error", { "restrictedNamedExports": ["default", "foo"] }]*/

export default function foo() {}

已知限制

此规则不检查再导出声明中源模块的内容。特别是，如果您从另一个模块的导出中重新导出所有内容，则该导出可能包含受限名称。此规则无法检测此类情况。

//----- some_module.js -----
export function foo() {}

//----- my_module.js -----
/*eslint no-restricted-exports: ["error", { "restrictedNamedExports": ["foo"] }]*/

export * from "some_module"; // allowed, although this declaration exports "foo" from my_module
