How can I use ESLint no-unused-vars for a block of code?

I need to disable some variable checks in ESLint.

Currently, I am using this code, but am not getting the desired result:

/* eslint no-unused-vars: ["error", { "caughtErrorsIgnorePattern": "Hey" }] */
export type Hey = {
  a: string,
  b: object
}

Two questions:

  • Is there a variant which can enable no-unused-vars for a block of code?

Something like…

/* eslint rule disable"*/

// I want to place my block of code, here

/* eslint rule disable"*/
  • Or could I make Hey a global variable so that it can be ignored everywhere?

Answer

To disable the @typescript-eslint/no-unused-vars warning:

  • For the current line:
const unusedVar = 1; // eslint-disable-line @typescript-eslint/no-unused-vars
  • For the next line:
// eslint-disable-next-line @typescript-eslint/no-unused-vars
const unusedVar = 1;
  • For a block:
/* eslint-disable @typescript-eslint/no-unused-vars */
const unusedVar1 = 1;
const unusedVar2 = 2;
/* eslint-enable @typescript-eslint/no-unused-vars */

Original answer

Just use pair of lines:

/* eslint-disable no-unused-vars */

// ... your code here with unused vars...

/* eslint-enable no-unused-vars */
