no-unused-vars issue

[lukasa1993]

i am getting warning 'ignored' is defined but never used @typescript-eslint/no-unused-vars with @epic-web/config/eslint on "eslint": "9.15.0" any other way to ignore variable ?

Here's how it's configured: https://github.com/epicweb-dev/config/blob/a38c8d04f3dff908dbc0f6b48dcd4377b8704a55/eslint.js#L116-L124

Prefix the variable with an underscore and that'll do it.

I'm not certain what the code looks like that you're trying to do this with so it's hard for me to help.

thanks for reply

{
    files: ["**/*.{ts,tsx}"],
    rules: {
      "@typescript-eslint/no-unused-vars": [
        "error",
        {
          args: "all",
          argsIgnorePattern: "^(_.*|e)$",
          caughtErrors: "all",
          caughtErrorsIgnorePattern: "^(_.*|e)$",
          destructuredArrayIgnorePattern: "^(_.*|e)$",
          varsIgnorePattern: "^(_.*|e)$",
          ignoreRestSiblings: true,
        },
      ],
    },
  },

this was my fix

Why the |e?

[lukasa1993]

noticed we use many catch (e) {} so i just added it :)

If you don't use the variable there you can just not provide it:

try {
} catch (e) {
}

is the same as:

try {
} catch {
}
