Using Bower Api in a synchronous way.

[Edmondo Porcu]

Dear all,

Bower API is based on asynchronous callbacks as described in the documentation. I am trying to use it with node the following way:

      var dependenciesTree = {};

      

      var _underscore = require('underscore');  

    

      bower.commands.list({paths:true},bowerConfig).on('end', function(tree){

          dependenciesTree = tree;

      });

    

    

      // Because of _underscore.pick apply signature, this is required

      var prodDependencies = _underscore.pick(dependenciesTree, _underscore.keys(bowerConfig.dependencies));

    

      var devDependencies = _underscore.pick(dependenciesTree, _underscore.keys(bowerConfig.devDependencies));

        

The following code does not yield the correct result because when entering the assignment of **prodDependencies** and **devDependencies**. I need it to be synchronous because it's inside my Gruntfile, so I could push the locking at a later stage, but I will have the same problem sooner or later.

How do I correctly wait for the command to be completed?

Thank you very much

Best Regards

Edmondo

Grunt supports async tasks, does that not help?

The problem here is that I am using bower api in grunt.initConfig, which is not a task I guess.

Hi,

I am looking for a way to run the bower commands synchronously too (especially list command) :ducks.

I want to require bower components in my js modules just by name and not by paths like './bower_components/jquery/jquery.js'.

The gist @ https://gist.github.com/Chandu/11216253 depicts what I would like to achive.

In brief,

1. I want to get the list of the modules currently installed and generate a map similar to {module_name => module_path}
2. Use this map (not the path |||lr to './bower_components.whatever/whatever.js') entries to require the bower components in my js modules

Is there a way to run the list command synchronously?

Thanks

I'd take a look at browserify or webpack ( http://webpack.github.io/ )
