html-validate

html-validate

Offline HTML5 validator. Validates either a full document or a smaller (incomplete) template, e.g. from an AngularJS or React component.

Features

• Can test fragments of HTML, for instance a component template.
• Does not upload any data to a remote server, all testing is done locally.
• Strict and non-forgiving parsing. It will not try to correct any incorrect markup or guess what it should do.

Usage

npm install -g html-validate
html-validate FILENAME..

Configuration

Create .htmlvalidate.json:

{
  "extends": [
    "htmlvalidate:recommended"
  ],

  "rules": {
    "close-order": "error"
    "void": ["warn", {"style": "omit"}]
  }
}

Test

npm run mocha
