What does it mean when TsLint says “expected callSignature to have a typedef.”

Question

I have a function in my code:

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


        

Answer 1

To avoid the build error. in the tslint.json file write code like:-

"typedef": [
  false,
  "call-signature"
],

This line of code in tslint.json does not make the return type of method required.
