# Linting / Error Checking

Vetur provides error-checking and linting.

# Error Checking

Vetur has error checking for the following languages:

  • <template>: html
  • <style>: css, scss, less
  • <script>: js, ts

You can selectively turn error checking off by vetur.validation.[template/style/script].

# Linting

Install ESLint plugin for the best linting experience. Vetur's template linting is only for quick start and does not support rule configuration.

After you installed ESLint plugin, add vue to eslint.validate in VS Code config:

  "eslint.validate": [
      "language": "vue",
      "autoFix": true

When configured correctly, ESLint should work for both <template> and <script>.

# Linting for <template>

Vetur bundles a version of eslint-plugin-vue for linting <template> section. Linting configuration is based on eslint-plugin-vue's essential rule set.

This linting is not configurable and based on a fixed version of eslint-plugin-vue. If you would like to configure the template linting rules:

To configure linting rules:

  • Turn off Vetur's template validation with vetur.validation.template: false

  • Make sure you have the ESLint plugin. The errors will come from ESLint plugin, not Vetur.

  • yarn add -D eslint eslint-plugin-vue in your workspace root

  • Set ESLint rules in .eslintrc. An example:

      "extends": [
      "rules": {
        "vue/html-self-closing": "off"

You can also checkout Veturpack to see how to setup eslint-plugin-vue.

# Linting TypeScript

TSLint is not available yet. We do look forward to including it. See #170.

Meanwhile, TS compiler errors will be shown.
