vue-eslint-parser and typescript-eslint problems #104

yoyo930021 · 2021-03-05T12:14:44Z

Reason: typescript-eslint/typescript-eslint#2865 (comment)

Hi, I'm using vue-eslint-parser and typescript-eslint in company project.
At the same time, I also help to contribute typescript-eslint project for fixing vue problems.

This problems are only happens when using type rules in typescript-eslint.
You need to add parserOptions.project in project to enable it.
https://github.com/typescript-eslint/typescript-eslint/blob/master/docs/getting-started/linting/TYPED_LINTING.md

There are two main issues:

performance issue

issues: #65, typescript-eslint/typescript-eslint#1180

The problem is that vue-eslint-parser is designed with the AST not type information.
The vue-eslint-parser will split code frame from template to @typescript-eslint/parser.
typescript-eslint/typescript-eslint#1180 (comment)
Typescript program need to parse full project for generate type information.
When parsing code frame, typescript program will reparse file AST and rebuild type information in project.
The vue-eslint-parser will pass more code frames and same file path in single Vue SFC.

Possible solutions:

Ignore parserOptions.project to close get type information when pass code frame.
Try to use ESLint processors, like Svelte.
Ref: Add fragment options to lint code fragment for Vue SFC performance typescript-eslint/typescript-eslint#1180 (comment)

[no-unsafe-*] rules

issues: typescript-eslint/typescript-eslint#2865

Strictly speaking, it isn't a problem with this project.
The typescript program can't parse Vue SFC file directly.

You may think it's strange, but why is it working now?
Because @typescript-eslint/parser will prioritize the content delivered from ESLint.
Typescript program will update by ESLint content not same as typescript program read.
But this problem is happens when ESLint not send file content and content from typescript program reading.
Example:

// App.vue
import HelloWorld from './components/HelloWorld.vue' // <- typescript program can't parse it. because it will read including template and style.

export default {
  name: 'App',
  components: {
    HelloWorld // <- so type information is `any`
  }
}

This problem will also have in <script setup> RFC.

Possible solutions:

Override HelloWorld.vue content.
Mock a HelloWorld.vue.ts file.

Maybe we need a common project for hacking typescript program.

Thanks for watching. Have a good day!

Thank you for organizing information.
(I take a long time to read English, so first I'm trying to understand performance issues. 😅)
I understand, thanks to your explanation, that the main cause is to call as many TS parsers as there are directives.

Ignore parserOptions.project to close get type information when pass code frame.

If this method solves the problem, I think it's the simplest change.
Is it possible for you to make this change and see if it improves performance?

Try to use ESLint processors, like Svelte.
Ref: typescript-eslint/typescript-eslint#1180 (comment)

I don't think we can use the ESLint processors.
It's difficult to change in vue-eslint-parser to do something similar to preprocessors, but I think it's more likely than ESLint processors.
As far as I can think of now, it's difficult to analyze variables in template scope.

My English is poor. If you don't understand what do I talk about, maybe I can ask for help. 😅

I will try again about this solution, and send a PR.
Maybe we can split two parser options for code frame and script. Ref: #65 (comment)

In the long run, we hope that the template can get the type information and rules.
There is actually no difference between parser and processors.
The parser also can compile templates to typescript and get type information with @typescript-eslint.
Perhaps the question is whether there is a need?

mariusheine · 2021-05-19T13:32:23Z

Are there any information, progress or ideas for the problem with the [no-unsafe-*] rules?

JounQin · 2021-07-06T10:01:54Z

@ota-meshi Even after #116, there is no way to only enable typescript rules for <script lang="ts">, right? Because we can only enable rules for *.vue files, not *.vue/*.ts.

ota-meshi · 2021-07-06T10:24:46Z

I know it.
I wrote #116 as "Related" because it may solve the performance issue depending on how it is used.

ota-meshi · 2021-07-06T23:27:19Z

I changed parserOptions.parser to allow multiple parsers.
If someone has an environment where they can try out performance issues, can you use the following configuration to see if it improves performance and share the results?

{
    "parser": "vue-eslint-parser",
    "parserOptions": {
        "parser": {
            "ts": "@typescript-eslint/parser",
            "<template>": "espree"
        }
    }
}

If performance improves, I think it's a useful workaround for many.

Produced same lint warning both times so reassuring. Is Unknown node type "ChainExpression": Estimated visitor keys ["type","start","end","loc","range","expression"] something to look into?

how to set different parser options for each parserOptions.parser ? @ota-meshi

ota-meshi · 2021-08-11T09:05:20Z

There is no way to do that.

simllll · 2021-08-16T17:57:00Z

If I run it via CLI
e.g. eslint src/file.ts --ext ts
it throws 7:13 error Parsing error: Unexpected token {
for

it seems it always picks "espree" instead of the rule that should forward it to the typesint-eslint/parser in case it's a ts file?

a possible workaround for now:

overrides: [
		{
			// enable the rule specifically for TypeScript files
			files: ['*.ts', '*.tsx'],
			parserOptions: {
				parser: '@typescript-eslint/parser'
			}
		}
	],

No method other than hacking @typescript-eslint/parser. =_=

I have an issue with this, if a vue file does not contain at least one TS script, the following error occurs:

Error: Error while loading rule '@typescript-eslint/await-thenable': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

Vue file:

Adding <script lang="ts"></script> fixes the issue.

Then you have to set parserOptions.project

MatthiasKunnen · 2021-08-31T12:20:02Z

I did. The first code block in my comment is a quote, not my actual config. My config is:

{
     parser: 'vue-eslint-parser',
     parserOptions: {
         parser: {
             '<template>': 'espree',
             js: 'espree',
             ts: '@typescript-eslint/parser',
         },
         project: ['./tsconfig.json'],
         extraFileExtensions: ['.vue'],
     },
}

         },
         project: ['./tsconfig.json'],
         extraFileExtensions: ['.vue'],
     },
}

In fact, @typescript-eslint/parser will not be applied for pure ts file, so you have to change js: 'espree' to js: '@typescript-eslint/parser'
You can see here:

vue-eslint-parser/src/common/parser-options.ts

Line 71 in 184dc09

return parser.js

MatthiasKunnen · 2021-08-31T13:34:07Z

I already tried that before. The problem is not with the js parser setting. With or without it, set to espreeor @typescript-eslint/parser, vue files cause the aforementioned error unless a script with lang="ts" is present.

Try out this repository: https://github.com/MatthiasKunnen/eslint-plugin-vue-ts-script.

of course you have to set the lang attribute. If it is omitted, the build tool also can not process your vue sfc written with ts.

@lovetingyuan, have you even looked at the linked repository? Please refrain from further replies with irrelevant information which cause unnecessary notifications and time waste for subscribers to this issue.

rndmerle · 2021-09-02T15:11:28Z

This config also works on our project (even if we had to keep that under an override for { files: ['**/*.vue'], parser: 'vue-eslint-parser' }.
And I confirm we had to add <script lang="ts">export default {}</script> to some of our stateless components missing it.

simllll · 2021-09-02T15:37:39Z

Try this config.

{
    "parser": "vue-eslint-parser",
    "parserOptions": {
        "parser": {
            "ts": "@typescript-eslint/parser",
            "js": "@typescript-eslint/parser",
            "<template>": "espree"
        }
    }
}

that's exactly what I have, but still need to override it for .ts files to get it working correctly.

Darkproduct · 2021-10-19T12:15:40Z

I'm currently struggling to get linting to work on my Laravel - Vue2 project with JavaScript and TypeScript. For debugging I created this small project, but I stumble from one issue to another.

First it seemed like I can't get the fragmented parser option, introduced in typescript-eslint/typescript-eslint#1180 to work, then I find typescript-eslint @TYPED_LINTING.md and now I'm stuck at:

$ eslint --config resources/js/.eslintrc.js --fix resources/js --ext .vue,.js,.ts

C:\fakepath\ts-test\resources\js\.eslintrc.js
  0:0  error  Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: resources\js\.eslintrc.js.
The file must be included in at least one of the projects provided

I've added those files to the tsconfig.json and even tried creating a tsconfig.eslint.json. But this doesn't work.

It it not at all clear to me, how @typescript-eslint/parser and this project should be configured to get proper linting.

segevfiner · 2022-08-11T13:38:50Z

Getting the same error. It looks like tsconfigRootDir and project isn't getting passed along to to @typescript-eslint/parser. Though even if it will get passed, it won't necessarily work due to the other issues described in this issue.

Scratch that. It is probably the missing <script setup lang="ts"> issue. I wonder if vue-eslint-parser can workaround this.

[no-unsafe-*] rules

I started a PoC to provide type information when importing components. But I still don't know if it works.

https://github.com/vuejs/vue-eslint-parser/tree/ts-poc

PR: #169

Please refer to the following changes regarding usage.
https://github.com/vuejs/vue-eslint-parser/pull/169/files#diff-f0d52672037b3876b9ee0769efb0a5ff277fed8a2eac978f5f7c13dca4ba52c6R30-R40

If you can copy this source code and try it, please try it and give me your opinion.

@yoyo930021 you can probably push directly to the branch. Feel free to push your changes to the branch if you need to.

jacekkarczmarczyk · 2022-09-30T11:01:28Z

I've tried the solution, my config is:

module.exports = {
  extends: ['jkarczm/vuetify'],
  parser: 'vue-eslint-parser',
  parserOptions: {
    parser: {
      ts: '@typescript-eslint/parser',
      '<template>': 'espree',
    },
    project: 'tsconfig.json',
  }
}

First tests show quite good results in terms of performance, however I've encountered another problem:

Parsing error: The keyword 'public' is reserved  vue/no-parsing-error

I'm using it ATM with vue 2.6 and vue cli, I'm in the process of switching to to 2.7, and maybe vite, so I won't bother now with further testing until I do the switch, but the code that uses public works perfectly fine and validates with my original eslint config

props: {
  public: Boolean,
  ...
}

and in template:

<v-col v-if="!public">...</v-col>

Not sure who's fault is this, just letting you know about the problem.

ota-meshi · 2022-09-30T11:14:36Z

After copying the source code of the poc branch and building it, try using it like this:

const parser = require('vue-eslint-parser')

module.exports = {
  parser: 'vue-eslint-parser',
  parserOptions: {
    parser: {
        ts: parser.createTSESLintParserForVue(),
        "<template>": {
            parseForESLint(code, options) {
                return require("@typescript-eslint/parser").parseForESLint(
                    code,
                    { ...options, project: undefined },
                )
            },
        },
    },
  }
}

jacekkarczmarczyk · 2022-09-30T11:27:33Z

Thanks for the suggestion, I've ended up with the following error

I have published a new package so that you can try the method described in #104 (comment) as a separate package.

https://github.com/ota-meshi/typescript-eslint-parser-for-extra-files
Please note that it is still experimental.

segevfiner · 2023-04-20T17:14:23Z

Was there any progress in getting this supported by this project?

@johnsoncodehk also have some works.

Just ran into this issue today, thank you @ota-meshi for this.

I searched on github for vue examples using this and followed this example which seemed to work well.

Following your demo/readme did not work out for me ota.

@kieselai mind sharing your config?

kieselai · 2023-06-28T18:07:26Z

Sure @DavidVaness, I'm referencing other files, but this should have all the important bits:

const parserForVue = require("typescript-eslint-parser-for-extra-files");

module.exports = {
  extends: [
    "plugin:vue/vue3-recommended",
    "@vue/eslint-config-typescript",
    "./eslint-shared-config-web.json",
  ],
  env: {

  },

Hello everyone, maybe someone can help me, i try to config ESLint with TypeScript-ESLint correctly, all errors are now showing, exapt which are inside tag, maybe someone can help me 🙂

          // Anything not matched in another group.
          ['^'],
          // Relative imports.
          // Anything that starts with a dot.
          ['^\\.'],
        ],
      },
    ],
    'simple-import-sort/exports': 'error',
  },
  root: true,
};

@romanhrynevych is that potentially a typescript error and not an eslint error?

6XGate · 2023-09-12T16:59:37Z

It seems the Vue project should look at the parser @ota-meshi made and integrate it into their ecosystem.

trash for vue3 ts lint。。。

yoyo837 · 2023-09-27T03:30:18Z

I changed parserOptions.parser to allow multiple parsers. If someone has an environment where they can try out performance issues, can you use the following configuration to see if it improves performance and share the results?
{
    "parser": "vue-eslint-parser",
    "parserOptions": {
        "parser": {
            "ts": "@typescript-eslint/parser",
            "<template>": "espree"
        }
    }
}
If performance improves, I think it's a useful workaround for many.

I got Parsing error: Maximum call stack size exceeded by the config.

…s/vue-eslint-parser#104 (comment) @ .eslintrc.cjs * re-order `overrides` to specify `settings.import/resolver.vite` over `*.vue`, `settings.import/resolver.typescript` over `*.ts` & rules over `.eslintrc.cjs`, * `eslint-disable @typescript-eslint/no-unsafe-member-access, @typescript-eslint/no-unsafe-call` @ main.ts * `eslint-disable` @ stats.js * fix the return type of `_.defaultsDeep()` is `any` @ `useQueryForm.fillParamDefaultValue()` - `shims-vue.d.ts` following vuejs/vue-eslint-parser#104 (comment) $ yarn add -D typescript-eslint-parser-for-extra-files @ fe

I dont know if this issue is the right place, but I want to make it popular because I sinked in around 2h of try and error for this.

extraFileExtensions: ['.vue'] is not read if it is in the eslint config overrides section.
It needs to be in parserOptions.extraFileExtensions in the root config.
All other override stuff, even parserOptions then can be put into overrides.files: ['*.vue']

One additional hurdle that I haven't seen mentioned yet: vue-eslint-parser does not appear to support either EXPERIMENTAL_useProjectService: true (which supports project references via TypeScript's project service) or project: true (which uses the nearest tsconfig.json as the project configuration for each file). You have to use the traditional way of passing the tsconfigs as an array of glob patterns.
