Vue-CLI with 4 space identation

Question

I am totally new to Vue.

I want to use the CLI and I want to have 4 space indentation (with typescript and vuex). But after 24 hours of struggling I am no closer to getting anything working. If it is impossible let me know too.

I thought that tslint was the way to go, but could not find a solution. So I tried eslint and added this to package.json

  "devDependencies": {
    "@vue/cli-plugin-eslint": "^3.0.4",
    "@vue/cli-plugin-pwa": "^3.0.4",
    "@vue/cli-plugin-typescript": "^3.0.4",
    "@vue/cli-service": "^3.0.4",
    "@vue/eslint-config-prettier": "^3.0.4",
    "@vue/eslint-config-typescript": "^3.0.4",
    "eslint": "^5.6.1",
    "eslint-plugin-vue": "^5.0.0-beta.3",      // <------------------
    "typescript": "^3.0.0",
    "vue-template-compiler": "^2.5.17"
  }

Then is eslintrc I have

 module.exports = {
    root: true,
    env: {
        node: true
    },
    extends: ["plugin:vue/essential", "@vue/prettier", "@vue/typescript"],
    rules: {
        "no-console": process.env.NODE_ENV === "production" ? "error" : "off",
        "no-debugger": process.env.NODE_ENV === "production" ? "error" : "off",
        "vue/script-indent": ["error", 4, { baseIndent: 1 }],
        indent: ["error", 4]
    },
    parserOptions: {
        parser: "typescript-eslint-parser"
    }
};

then when I run

$ npx eslint --fix *.js

  3 errors and 0 warnings potentially fixable with the `--fix` option.
but the problem is that no files ever get changed.

As described in the tslint doc, the indent rule doesnt fix wrong amount of indentation characters, it only fixes the character type, this means that it can convert tabs to spaces and vice versa, but it doesnt fix 4 spaces to 2 spaces

NOTE: auto-fixing will only convert invalid indent whitespace to the desired type, it will not fix invalid whitespace sizes.

So yeah, you'd have to go with eslint. I dont see you full eslintrc file, but I think that the main problem may be this line: indent: ["error", 4]. Try removing that.

This eslint config is working for me:

{
    "root": true,
    "env": {
      "node": true
    },
    "extends": [
      "plugin:vue/essential",
      "eslint:recommended",
      "@vue/typescript"
    ],
    "rules": {
      "vue/script-indent": ["error",2,{"baseIndent": 1}]
    },
    "parserOptions": {
      "parser": "typescript-eslint-parser"
    }
}

And run with npm run lint
