这个箭头函数体可以通过省略大括号和关键字'return'来简化。tslint(arrow-return-shorthand)

Question

My purpose is read a file json with all name of my input's project

{ 'home':'home'}:

and I create the service but I do this:

getPropertiesName(): Observable<Object> {
    return this.http.get('assets/config/propertiesName.json').pipe(map((response: Response) => {  return response.json(); }));
  }

The problem is that the compiler gives me this error:

This arrow function body can be simplified by omitting the curly braces and the keyword 'return'.tslint(arrow-return-shorthand)

Anyone can help me to resolve this?

Answer 1

adsds it's the same

this.http.get(...).pipe(map((response: Response) => {  return response.json(); }));

than

this.http.get(...).pipe(map((response: Response) => response.json();));

BTW, your response is yet a json, has no sense convert to json

Answer 2

This is a lint error from tslint, and is likely auto fixable. Try running:

ng lint --fix

And then consider the diff in conjunction with the error message you posted.
