当 TsLint 说“预期 callSignature 有一个 typedef"是什么意思.

问题描述

我的代码中有一个函数:

I have a function in my code:

networkStop = (action: string = null) => {
    this.action[action] = false;
    this.net = false;
    this.netd = false;
}

我收到 TsLint 错误消息:

I'm getting a TsLint error saying:

Message 4   TsLint: expected callSignature to have a typedef.

谁能解释一下这是什么意思?

Can someone explain what this means?

推荐答案

"Missing Type definition" 参见:https://github.com/palantir/tslint/blob/master/src/rules/typedefRule.ts 了解详情.基本上 some 注释(对于函数，因为 callSignature)缺失.

"Missing Type definition" See : https://github.com/palantir/tslint/blob/master/src/rules/typedefRule.ts for details. Basically some annotation (for a function because callSignature) is missing.

可能是修复(明确指定返回类型):

Probably the fix (specify the return type explicitly) :

networkStop = (action: string = null):void => {
    this.action[action] = false;
    this.net = false;
    this.netd = false;
}
