Extended rules for eslint

To use any of these rules, you need to install the package:

pnpm add -D @lucasols/eslint-plugin-extended-lint

And then configure it in your eslint config:

{
  "plugins": ["@lucasols/extended-lint"],
  "rules": {
    "@lucasols/extended-lint/no-unused-type-props-in-args": "error"
  }
}

no-unused-type-props-in-args

Checks if there are unused type props in function arguments.

Examples

Bad

function foo({ a }: { a: string; b: string }) {
  /*                             ^ b is declared but not used in the function */
  // ...
}

Good

function foo({ a, b }: { a: string; b: string }) {
  // ...
}

It will also work with the react FC type:

Bad

const Foo: FC<{ a: string; b: string }> = ({ a }) => {
  /*                       ^ b is declared but not used in the component */
  // ...
}

Good

const Foo: FC<{ a: string; b: string }> = ({ a, b }) => {
  // ...
}

• This rule will not work in all situations, as it does not checks all possible usages of referenced types.

no-commented-out-code

Checks if there are commented code. Block comments are ignored.

Examples

Bad:

// function foo() {
//   // ...
// }

Good:

/*
function foo() {
  // ...
}
*/

• This rule will not detect all possible commented code, and can give false negatives.

no-call-with-infered-generics

This rule disallows calling functions with inferred generics.

The rule options types are as follows:

type Options = [
  {
    functions: Array<{
      name: string;
      minGenerics?: number;
      allowAny?: boolean;
      disallowTypes?: string[];
    }>;
    anyAliases?: string[];
  }
];

Examples:

Bad:

```ts
// @typescript-eslint/no-call-with-inferred-generics: ["error", { functions: ["foo"] }]

function foo<T>(arg: T) {
  // ...
}

foo('bar') // Error: Generics must be defined explicitly
foo<any>('bar') // Error: 'any' is not allowed in generics

Good:

// @typescript-eslint/no-call-with-inferred-generics: ["error", { functions: ["foo"] }]
function foo<T>(arg: T) {
  // ...
}

foo<string>('bar') // OK

rules-of-hooks

A fork of the eslint-plugin-react-hooks rules-of-hooks rule, but with the following changes:

• Identifies hooks in camelCase namespaced functions (e.g. test.useFoo())
