需要返回类型的箭头 function 的 ESLint 规则

Question

I'm having below arrow function in my angular project:

this.httpClient.get('url').subscribe((response)=>{

});

In the above code ESLint should throw an error for not specifying return type.

Answer 1

Check the rule @typescript-eslint/explicit-function-return-type . You need to set the option allowTypedFunctionExpressions to false . If you are using.eslintrc:

"@typescript-eslint/explicit-function-return-type": [
  "error",
  {
    "allowTypedFunctionExpressions": false
  }
]
