使用 ESLint 而不是 PascalCase 强制使用camelCase

Question

我正在为我的项目设置 ESlint，我有一个问题。

我希望以下内容起作用：

class MyClass {

}

function awesomeFunction() {

}

let myVariable = "a";

但不是这个：

class myClass {

}

function AwesomeFunction() {

}

let MyVariable = "a";

我希望所有变量和函数都是驼峰式（而不是 PascalCase），所有类都是 PascalCase（而不是驼峰式）。

有人可以帮我吗？ 提前致谢！

Answer 1

现在这对于打字稿来说似乎是可能的。

根据https://github.com/typescript-eslint/typescript-eslint/pull/1318你可以指定这样的配置：

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

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

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

  { selector: "typeLike", format: ["PascalCase"] },
  { selector: "typeParameter", format: ["PascalCase"], prefix: ["T"] },

  { selector: "interface", format: ["PascalCase"], custom: { regex: "^I[A-Z]", match: false } },
],
}

应该可以借助 id-match 规则在 eslint 中进行。 我找到了一个可以解决它的插件，但目前它似乎有点坏。

应该是“@typescript-eslint/naming-convention”而不是“@typescript-eslint/naming-conventions”，如伊恩的回答所示。

对于上下文，这是我的 .eslintrc.json 文件：-

    "parser": "@typescript-eslint/parser",
    "plugins": [
        "@typescript-eslint"

        "@typescript-eslint/type-annotation-spacing": "error",
        "@typescript-eslint/space-infix-ops": "error",
