Rules

@lvjiaxuan/no-spaces-on-empty-line

const foo = 1
···// A few spaces which would be detected and removed by this rule.
const bar = 2

After soon, I found it as well as no-trailing-spaces. So I set it deprecated, f--king sad.

@lvjiaxuan/prefer-constraint-tuple-type

type Foo<BarArr = []> = [ ...BarArr ] // A rest element type must be an array type.(2574)

Maybe BarArr is better to extend a constraint type even unknown.

type Foo<BarArr extends unknown[] = []> = [ ...BarArr ] // ok.

@lvjiaxuan/no-multi-empty-lines-in-pattern

options:

const options1 = { '@lvjiaxuan/no-multi-empty-lines-in-pattern': [ 'warn', { afterMaxLines: 0, beforeMaxLines: Infinity } ] } // default

const options2 = {
  '@lvjiaxuan/no-multi-empty-lines-in-pattern': [
    'warn',
    {
      ObjectExpression: { afterMaxLines: 0, beforeMaxLines: Infinity },
      // ObjectPattern:
      // ArrayExpression:
      // ArrayPattern:
    },
  ],
}

const options3 = {
  '@lvjiaxuan/no-multi-empty-lines-in-pattern': [
    'warn',
    { afterMaxLines: 0, beforeMaxLines: Infinity },
    {
      ObjectExpression: { afterMaxLines: 2, beforeMaxLines: 2 },
      // ObjectPattern:
      // ArrayExpression:
      // ArrayPattern:
    },
  ],
}

const obj = {
  a: 1,
  b: 2
// This line Would be fixed through removing.
// This line Would be fixed through removing.
}

const {
  a,
  b,
// This line Would be fixed through removing.
// This line Would be fixed through removing.
} = obj

const arr = [

const [
