grunt-htmllint-http

Grunt plugin for html validation, using the vnu.jar markup checker.

This is grunt plugin only accepts url's as input. If you want to lint local files, take a look at grunt-html.

Getting Started

Install this grunt plugin next to your project's gruntfile with: npm install grunt-htmllint-http --save-dev

Then add this line to your project's gruntfile:

grunt.loadNpmTasks('grunt-htmllint-http');

Then specify what url's to validate in your config:

grunt.initConfig({
    'htmllint-http': {
        dist: {
            urls: [
                'http://localhost/',
                'http://localhost/articles.html',
                'http://localhost/articles/interesting-fact.html'
            ]
        }
    }
});

Then run it like this:

grunt htmllint-http

Options

ignore

An array of messages you don't want to report as error. Example config:

'htmllint-http': {
    options: {
        ignore: [
            'Bad value “X-UA-Compatible” for attribute “http-equiv” on XHTML element “meta”.',
            'Bad value “apple-mobile-web-app-title” for attribute “name” on XHTML element “meta”: Keyword “apple-mobile-web-app-title” is not registered.'
        ]
    },
    dist: {
        urls: [
            'http://localhost:1337/',
            'http://localhost:1337/articles.html'
        ]
    }
}

parallelLimit

Starting vnu.jar requires quite a bit of time and resources. To prevent clogging your machine when linting a large amount of files, a concurrency limit is in order. This defaults to the number of cores your cpu has.

'htmllint-http': {
    options: {
        parallelLimit: (require('os').cpus().length * 2)
    },
    dist: {
        urls: (function() {
            return glob.sync('src/**/*.html') // A LOT of files
                .map(function(file) {
                    return file.substr(3);
                })
                .filter(function(file) {
                    return !file.substr(0, 8) === '/layout/';
                })
                .map(function(file) {
                    return 'http://localhost:' + config.server.port + file;
                });
        }())
    }
}
