not sure if the express is old version.

    throw err;
          ^
Error: Cannot find module 'C:\Users\Brian\Documents\GitHub\angular-express-blog\api.js'
    at Function.Module._resolveFilename (module.js:336:15)
    at Function.Module._load (module.js:278:25)
    at Function.Module.runMain (module.js:501:10)
