Automate npm and bower install with grunt

Question

I have a node / angular project that uses npm for backend dependency management and bower for frontend dependency management. I\'d like to use a grunt task to do both install co

You need to tell grunt that you're using an async method (.exec) by calling the this.async() method, getting a callback, and calling that when exec is done.

This should work:

module.exports = function(grunt) {
    grunt.registerTask('install', 'install the backend and frontend dependencies', function() {
        var exec = require('child_process').exec;
        var cb = this.async();
        exec('bower install', {cwd: './frontend'}, function(err, stdout, stderr) {
            console.log(stdout);
            cb();
        });
    });
};
