Grunt compress : How could I only include runtime node module dependencies? - node.js

Question

My application is MEAN stack style. I would like to generate a package including all Nodejs and AngularJs files, so I could just unzip the package and run in other environments.
I use grunt-contrib-compress to compress and generate a zip file. Everything works well, but there are many development node modules are included, such as grunt*. All I need is the runtime node modules which are defined in the package.json. It will dramatically reduce the package size.
I could include the node modules one by one, but is there a good way only include runtime modules while packaging?

Answer 1

OK, I found a solution, which load the package.json and map the runtime dependencies into target folders.
compress: {
main: {
options: {
archive: 'myapp.zip'
},
files: [
{src: ['dist/**','app/**','config/**','server.js'],dest:'.'},
{src: Object.keys(require('./package.json').dependencies).map(function(module){
return "node_modules/" +module+"/**"
}),dest:'.'},
]
}
}

I had exactly the same question today, and after asking and coming up with a very similar solution, I have found your question. Here is my, similar but slightly different approach:
function getDependencies(pkg) {
return Object.keys(pkg.dependencies).map(function(val) { return val + '/**'; });
}
module.exports = function(grunt) {
var pkg = grunt.file.readJSON('package.json');
var config = {
pkg: pkg,
clean: ["public/"],
compress: {
validate: {
options: {
archive: 'public/Lambda.zip'
},
files: [
{ expand: true, cwd: 'src/', src: ['**'], dest: '/' },
{ expand: true, cwd: 'node_modules/', src: getDependencies(pkg), dest: '/node_modules' }
]
}
}
};
grunt.initConfig(config);
grunt.loadNpmTasks('grunt-contrib-clean');
grunt.loadNpmTasks('grunt-contrib-compress');
grunt.registerTask('build', ['clean', 'compress']);
}
