eslint-plugin-html

This ESLint plugin extracts and lints scripts from HTML files.

Supported HTML extensions: .html, .xhtml, .htm, .vue, .hbs, .mustache

Only script tags with no type attribute, with a type attribute containing a standard JavaScript MIME type such as text/javascript or application/javascript, or text/babel will be linted.

Usage

Simply add the plugin to your ESLint configuration. See ESLint documentation.

Example:

{
    "plugins": [
        "html"
    ]
}

Settings

By default, the code between <script> tags is dedented according to the first non-empty line. The setting html/indent allows to ensure every script tags follows an uniform indentation. Like the indent rule, you can pass a number of spaces, or "tab" to indent with one tab. Prefix this value with a + to be relative to the <script> tag indentation. Example:

{
    "plugins": [ "html" ],
    "settings": {
      "html/indent": "0",   // code should start at the beginning of the line (no initial indentation).
      "html/indent": "+2",  // indentation is the <script> indentation plus two spaces.
      "html/indent": "tab", // indentation is one tab at the beginning of the line.
    }
}

By default, this plugin won't warn if it encounter a problematic indentation (ex: a line is under indented). If you want to make sure the indentation is correct, use the html/report-bad-indent in conjonction with the indent rule. Pass 1 to display warnings, or 2 to display errors. Example:

{
    "plugins": [ "html" ],
    "settings": {
      "html/report-bad-indent": 2,
    }
}
