ってあれっ、なんかエラーが。

camelcaseとclass-name-casingの廃止

Change Logを見に行くとこんな記述が。

https://github.com/typescript-eslint/typescript-eslint/releases/tag/v3.0.0

The following deprecated rules have been deleted. Please switch to the listed alternative:

• ban-ts-ignore - replaced by ban-ts-comment
• camelcase - replaced by naming-convention
• class-name-casing - replaced by naming-convention
• generic-type-naming - replaced by naming-convention
• interface-name-prefix - replaced by naming-convention
• member-naming - replaced by naming-convention
• no-untyped-public-signatures - replaced by explicit-module-boundary-types

naming-conventionってやつに置き換えろってことらしい。

naming-convention

をみると、だいぶわちゃわちゃしている。

eslintのcamelcase相当

{
  "@typescript-eslint/naming-convention": [
    "error",
    {
      "selector": "default",
      "format": ["camelCase"]
    },

    {
      "selector": "variable",
      "format": ["camelCase", "UPPER_CASE"]
    },
    {
      "selector": "parameter",
      "format": ["camelCase"],
      "leadingUnderscore": "allow"
    },

    {
      "selector": "memberLike",
      "modifiers": ["private"],
      "format": ["camelCase"],
      "leadingUnderscore": "require"
    },

    {
      "selector": "typeLike",
      "format": ["PascalCase"]
    }
  ]
}

編集時点でcustomとfilterの使い方が全くわかりません。

自分の掛けたいルールは

• 基本camelCaseに
• でもtypeで作ったエイリアスはPascalCaseに
• プロパティは何もしない
• 変数名_を許容したい

なので・・・ええっとつまり・・・
