how can I open web application requiring node.js

I must run micro-crawler https://github.com/WebMole/Micro-Crawler which is a crawler web application, that run with node.js. I could not figure out how to open this app, I download node.js, and when I write install npm and install bower to the node.js command line nothing happened. Also I did not understand how to start web applicaion after installations

Please help me

Finally I solved the issue

  • First, I install node.js, then move node.js folder to wampserver directory, and move the web sites files in the node.js directory
  • Second, I go to the path where node.js is from command line, then enter "install npm" command line
  • The error appeared in this phase for solving I create a npm folder in c:users/user_name_of_your_computer/app_data/roaming then I installed git and enter the directories of bin and cmd files of git to the system enviroments/path
  • Third I enter the commands "bower install" and "npm install -g grunt-cli" from the comand. from the path of where node.js is

and the micro-crawler works

Did you execute your .js file? You can do that with node.js cli thus:

path/to/your/file: node file.js
