grunt-vnuserver

Grunt plugin for starting the vnu.jar markup checker in server mode. Plays well with grunt-html for faster HTML validation by only starting vnu.jar once, as startup can take a few seconds.

Getting Started

Install this grunt plugin next to your project's Gruntfile.js with:

npm install grunt-vnuserver --save-dev

Then add this line to your project's Gruntfile.js:

grunt.loadNpmTasks('grunt-vnuserver');

Options

port

• Type: Number
• Default: 8888

The port on which to start the server.

all: {
  options: {
      port: 8877
  },
}

skippable

• Type: Boolean
• Default: false

Whether or not to skip server startup if port is already in use. Task will fail if port is in use and skippable is false.

persist

• Type: Boolean
• Default: false

Whether or not to keep the vnu server running even after grunt exists. If false, vnu server is killed when grunt exists.

Example

Consider the following configuration in Gruntfile.js in which the watch task is set to run htmllint every time the source file changes. By starting the validator in server mode once using the vnuserver task, validations by htmllint can be performed much faster by simply connecting to this already-running server.

module.exports = function (grunt) {
    grunt.initConfig({
        vnuserver: {
        },
        htmllint: {
            all: {
                options: {
                    // This option makes grunt-html connect to the vnu server instance.
                    server: {}
                },
                src: "app.html"
            }
        },
        watch: {
            all: {
                tasks: ['htmllint'],
                files: "app.html"
            }
        },
    });
 
    grunt.loadNpmTasks('grunt-vnuserver');
    grunt.loadNpmTasks('grunt-html');
    grunt.loadNpmTasks('grunt-contrib-watch');
 
    grunt.registerTask('default', ['vnuserver', 'watch']);
};
