javascript/typescript - 通过 eslint 规则强制将 object 作为 function 参数传递

Question

Is it possible to force the following rule by eslint?

• if the number of function arguments is more than one, use "object" as an argument.

For example,

• good
  • const f = (x: string) =>...
  • const f = (x: {id: string}) =>...
  • const f = (x: {id: string; name: string}) =>...
• bad
  • const f= (x: string; y: string) =>...

I checked the official document ( https://eslint.org/docs/rules/ ), but I couldn't find appropriate rules. I wonder if some kind of custom rules can realize this.

Answer 1

You can use max-params rule. https://eslint.org/docs/rules/max-params Set the max value to 1 .
