Vetur: 0.11.0 format JS still doen't obey eslint-prettier

[islishude]

• [x] I have searched through existing issues
• [x] I have read through docs at https://vuejs.github.io/vetur/
• [x] I have read FAQ: https://github.com/vuejs/vetur/wiki/FAQ

Info

• Platform: Win
• Vetur version:
• VS Code version: 1.17.2

Problem

The new vertion 0.11.0 I updated just now

my setting snippet

{
  "prettier.eslintIntegration": true,
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    {
      "language": "html",
      "autoFix": true
    },
    {
      "language": "vue",
      "autoFix": true
    }
  ],
  "eslint.autoFixOnSave": true,
  "eslint.alwaysShowStatus": true,
  "eslint.options": {
    "plugins": ["html"]
  },
  "vetur.format.defaultFormatter.html": "js-beautify-html"
}

Reproducible Case

<template>
    <div>
        test vue.
    </div>
</template>
<script>
export default {
  name: "test", // here not obey eslint-standard 
  methods: {
    test() { // here not obey eslint-standard 
      console.log("test"); // here not obey eslint-standard 
    }
  }
}; // here not obey eslint-standard 
</script>

What's your .eslintrc and package.json's dependencies?
Does it not work on https://github.com/octref/veturpack too?

[FFxSquall]

At me too does not work. I use https://github.com/vuejs-templates/webpack
.eslintrc

// https://eslint.org/docs/user-guide/configuring

  // check if imports actually resolve

I see the problem. Will take a look tonight. Thanks.

[octref]

The problem comes from ESLint wants to do the <script> extraction by itself, whereas Vetur just passes in the extracted <script> section

[octref]

I'll follow up with a PR: https://github.com/vuejs-templates/webpack/issues/901

Meanwhile, you can try this setup:

• Clone veturpack
• npm i eslint-config-standard eslint-plugin-standard
• Update your .eslintrc so it extends standard too

{
  "extends": [
    "eslint:recommended",
    "plugin:vue/recommended",
    "standard"
  ],
  "rules": {
    "import/no-unresolved": 0,
    "import/no-unassigned-import": 0,
    "vue/html-no-self-closing": "error",
    "semi": ["error", "never"],
    "no-console": "off",
    "space-before-function-paren": [
      "error",
      {
        "anonymous": "always",
        "named": "always",
        "asyncArrow": "always"
      }
    ]
  }
}

seems to default to none for html: I had to set "vetur.format.defaultFormatter.html": "js-beautify-html" in vscode settings.

[pillarlee16]

@octref, I've also faced a similar issue.

When "prettier.eslintIntegration" is true, I expected that if I run vscode 'Format Document' option, it will fix the differences of eslint in script tag.

<!-- App.vue (before) -->
<template>
</template>

<script>
import HelloWorld from './components/HelloWorld';

export default {
  name: 'app',
  components: {
    HelloWorld,
  },
  methods: {
    foo: function () {
      return 'bar';
    },
  },
};
</script>

<style>
</style>

<!-- App.vue (expected) -->
<!-- object-shorthand (https://eslint.org/docs/rules/object-shorthand) should be fixed -->
<template>
</template>

<script>
import HelloWorld from './components/HelloWorld';

export default {
  name: 'app',
  components: {
    HelloWorld,
  },
  methods: {
    foo () {
      return 'bar';
    },
  },
};
</script>

<style>
</style>

However, prettier part of prettier-eslint works, but eslint part doesn't work.

As you mentioned,
ESLint parsers (both eslint-plugin-html and vue-eslint-parser) check whether file extension is '.vue' and then requires code string includes script tag.

In addition,
https://github.com/vuejs/vetur/blob/25a4151a6cd424655ba7cec3042c3abb6811391a/server/src/utils/prettier/index.ts#L42-L45
when this code run 'prettier-eslint', it doesn't pass filePath.
when I tested vetur in vscode debugger (I followed https://vuejs.github.io/vetur/CONTRIBUTING.html), it failed to retrieve proper eslint configs because that filePath was missing.

My poor solution was that it just replaces '.vue' of filePath with '.js' when it passes values to 'prettier-eslint' and it worked.
However, I don't think that this is a proper approach.

[octref]

I'd suggest moving away from eslint-plugin-html to eslint-plugin-vue which is the official dedicated eslint plugin from @vuejs.

eslint-plugin-html won't contain many of the autofix in eslint-plugin-vue, so even if prettier-eslint runs through prettier -> eslint --autofix, the output with eslint-plugin-html won't be good enough.

It was working for me in https://github.com/octref/veturpack -- what's your project structure where it didn't find the correct .eslintrc?

I also tried passing in filePath with .vue but it didn't work so I left it out. Changing to .js sounds really hacky to me too...

[karlhorky]

Is this actually working with veturpack without the .prettierrc file? If I delete this file it does not seem to read the ESLint config correctly. It then autoformats to incorrect syntax:

I tried the instructions in https://github.com/vuejs/vetur/issues/521#issuecomment-342560578 (this also needed eslint-plugin-node - see error message below) but that didn't seem to help.

Installation error message with -standard packages:

Failed to load plugin node: Cannot find module 'eslint-plugin-node' Referenced from: /Users/k/p/veturpack2/.eslintrc

---

Detailed list of what I did:

1. Cloned veturpack
2. npm install
3. npm install eslint-config-standard eslint-plugin-standard
4. npm install eslint-plugin-node
5. rm .prettierrc
6. code .
7. Opened Counter.vue and add a line before the <script> tag. It will autoformat to incorrect syntax.

[dmzkrsk]

I can confirm the behaviour described by @karlhorky
prettier-eslint does NOT find eslint config when filePath is empty

There's another fix:

Don't rename '.vue' to '.js', just pass directory name to eslint!

const prettierifiedCode = prettierEslint({ filePath: require("path").dirname(filePath), text: code, fallbackPrettierOptions: prettierOptions });
