javascript - 使用 ESLint 而不是 PascalCase 强制执行 camelCase

Question

我正在为我的项目设置 ESlint，我有一个问题。

我希望以下工作：

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 camelCase（而不是 PascalCase），所有类都是 PascalCase（而不是 camelCase）。

有人可以帮我吗？提前致谢！

Answer 1

现在打字稿似乎可以做到这一点。

根据https://github.com/typescript-eslint/typescript-eslint/pull/1318您可以像这样指定配置：

{
"@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 } },
],
}

在 id-match 规则的帮助下，应该可以在 eslint 中进行操作。我找到了一个可以解决它的插件，但目前它似乎有点坏了。

应该是“@typescript-eslint/naming-convention”而不是“@typescript-eslint/naming-conventions”，如 Ian 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"
    ],
    "extends": [
        "eslint:recommended",
        "plugin:@typescript-eslint/eslint-recommended",
        "plugin:@typescript-eslint/recommended"
    ],
    "rules": {
        "@typescript-eslint/type-annotation-spacing": "error",
        "@typescript-eslint/space-infix-ops": "error",
        "@typescript-eslint/naming-convention": [
            "error",
            {
                "selector": "default",
                "format": [
                    "camelCase"
                ]
            },
            {

                "prefix": [
                    "T"
                ]
