warp.firstclass/index.js

Allows to access all your modules directly like: require('moduleName') by creating symlinks

var link = require('fs-symlink'),
    _ = require('lodash'),
    promise = require('bluebird'),
    fs = require('fs');

module.exports = {
    link: function(dirToLink){
        if (!dirToLink){
            throw new TypeError("No 'dirToLink' argument provided");
        } else {
            console.log('Running warp.firstclass');
        }

        var opts = {
            dirToLink: format(dirToLink)
        };
        var dirs = fs.readdirSync(opts.dirToLink);
        var dirsToLink = _.filter(dirs, function(dir){
            return !/\./.test(dir); // only directories, no files allowed
        });

        return promise.each(dirsToLink, function(dir){
            var from = './node_modules/' + dir,
                to = opts.dirToLink + dir ;

            console.log('creating symlink from %s to %s', from, to);

            if (/^win/.test(process.platform)) {
                return link( to , from, 'junction');
            } else {
                return link( to , from, 'dir');
            }
        }).then(function () {
            console.log('done');
            return promise.resolve()

        }).catch(function(err){
            console.log(err);
            return promise.reject(err);
        });

        function format(dir){
            // add forward slash in the end if needed
            return /\/$/.test(dir)?dir : dir+'/';
        }
    }
};

if (__filename == process.argv[1]){
    // start  if invoked directly
    var dirToLink = process.argv[2];
    module.exports.link(dirToLink);
}
