Usage with Vue.js

Using vue-cli-service

vue add html-validate

Adds the required libraries and preconfigures .vue transformations. A configuration is dropped in the project root directory with recommended configuration for Vue.js.

Adds a new CLI service command:

vue-cli-service html-validate

Validates all .html and .vue files in the src folder. Patterns can be overwritten by passing them as positional arguments.

Using nuxt

yarn add --dev @nuxtjs/html-validator

Then add the Nuxt module to your nuxt.config.js:

export default {
  buildModules: ["@nuxtjs/html-validator"],
  htmlValidator: {
    options: {
      // you can pass options directly to `html-validate`

You can find more details in the documentation.

The module will then validate all server-rendered and server-generated HTML with html-validate.

Manual configuration

npm install html-validate-vue

html-validate-vue is needed to transform .vue single file components and includes elements metadata overrides for Vue.js.

Configure with:

  "plugins": ["html-validate-vue"],
  "extends": ["html-validate:recommended", "html-validate-vue:recommended"],
  "elements": ["html5"],
  "transform": {
    "^.*\\.vue$": "html-validate-vue"
