Issues with Postcss config in gruntfile - gruntjs

Question

Quick question, trying to get postcss to work and keep getting
"SyntaxError: /Users/todd.kidder/Documents/sitecore-site/Gruntfile.js:40
>> });"
error when I go to run the default task.
I'm sure the error is obvious but totally new at this, I'm a css grunt by trade.
Appreciate any help I can get on this.
module.exports = function(grunt) {
// 1. All configuration goes here
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uncss: {
dist: {
files: {
'cleaned-css/tidy.css': ['index.html']
}
}
},
cssnano: {
options: {
sourcemap: true
},
dist: {
files: {
'cleaned-css/tidy.css': 'cleaned-css/tidy.css'
}
}
},
postcss: {
options: {
map: true,
processors: [
require('autoprefixer-core')({
browsers: 'last 2 version'
}).postcss,
]
},
dist: {
expand: true,
flatten: true,
src: 'cleaned-css/tidy.css'
}
}
}
});
// 3. Where we tell Grunt we plan to use this plug-in.
grunt.loadNpmTasks('grunt-uncss');
grunt.loadNpmTasks('grunt-cssnano');
grunt.loadNpmTasks('grunt-postcss');
grunt.loadNpmTasks('autoprefixer');
// 4. Where we tell Grunt what to do when we type "grunt" into the terminal.
grunt.registerTask('default', ['uncss', 'postcss']);
grunt.registerTask('build', ['uncss', 'postcss', 'cssnano']);
};

i think the problem is a simple typo issue.
Please try this one:
module.exports = function(grunt) {
// 1. All configuration goes here
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uncss: {
dist: {
files: {
'cleaned-css/tidy.css': ['index.html']
}
}
},
cssnano: {
options: {
sourcemap: true
},
dist: {
files: {
'cleaned-css/tidy.css': 'cleaned-css/tidy.css'
}
}
},
postcss: {
options: {
map: true,
processors: [
require('autoprefixer-core')({
browsers: 'last 2 version'
}).postcss,
]
},
dist: {
expand: true,
flatten: true,
src: 'cleaned-css/tidy.css'
}
}
})
};
// 3. Where we tell Grunt we plan to use this plug-in.
grunt.loadNpmTasks('grunt-uncss');
grunt.loadNpmTasks('grunt-cssnano');
grunt.loadNpmTasks('grunt-postcss');
grunt.loadNpmTasks('autoprefixer');
// 4. Where we tell Grunt what to do when we type "grunt" into the terminal.
grunt.registerTask('default', ['uncss', 'postcss']);
grunt.registerTask('build', ['uncss', 'postcss', 'cssnano']);
Hope that helps.
