My attempt at a lazy-loading coffee task

Gruntfile.js

module.exports = function(grunt) {
    
    grunt.initConfig({
    
        pkg: grunt.file.readJSON('package.JSON'),
        watch: {
            files: ['src/**/*.coffee', 'test/**/*.coffee', "app.coffee"],
            task: ['coffeelint']
        },
        coffeelint: {
            src: ['src/**/*.coffee', 'test/**/*.coffee'],
            options: {
                indentation: {
                    value: 4,
                    level: 'warn'
                }
            }
        }

    });

    grunt.event.on('watch', function(action, filepath, target) {
        //console.log(target + ': ' + filepath + ' has ' + action);
        console.log(coffeelint);
        grunt.config.set('coffeelint', {
            changed: {
                app: filepath,
                force: true
            }
        });
        grunt.config.set('coffee', {
            changed: {
                options: { bare: true, sourceMap: true },
                files: [{ src: filepath, dest: "src/js", ext: '.js' }]
            }
        });
        grunt.task.run(['coffeelint:changed', 'coffee:changed']);
    });


    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.loadNpmTasks('grunt-contrib-coffee');
    grunt.loadNpmTasks('grunt-coffeelint');

    grunt.registerTask('default', ['watch']);
};
