I am not able to load my json file

The console logs this message

XMLHttpRequest cannot load file:///C:/wamp/www/angular-tut/mock/todos.json. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

The object 'todos' works when I have it in the main app.js file but as soon as I make a call for it with the service it breaks. I would be grateful for any help

Simple mistake a lot of us make specially in the beginning. What happens is you are trying to make a server request to get your JSON file, but you dont have a server running.

file:///C:/wamp/www/angular-tut/mock/todos.json.

Thats just your static file, you would need to use localhost:8000 to be able to correctly run a angular get request to retrieve the json file. That is why when you have the object in the main.js it works its because its is not making a get request so doesn't need a server running. Use MAMP or php local server to get your localhost going, tree house has a great lesson on installing and using localhost.

What Caesar Bell said except there's no need for MAMP. Why run a php server when you can run a nodeJS server with equal or less effort? Here's what you do:

  1. Install NodeJS // Hint: If you're on a Mac, you want to install and use Homebrew for this
  2. Open your favorite terminal emulator
  3. Install http-server by running: npm install http-server -g
  4. Start http-server by running: http-server 'path/to/your/angular/root/directory' -o
  5. That last command — specifically, the -o flag — should open a browser window at: localhost:8080

Your angular app should work now; just type in localhost:8080 in your browser's address bar. Remember that from now on — assuming you've completed steps 1-3 above — anytime you desire a server instance, all you have to do is step 4.

Thanks Mikis , Ceaser and Akak. I thought I was going crazy but I guess it makes sense now. Special thanks to Mikis for the extra knowledge about Node

Try using different browser. Chrome is known for blocking local ajax requests.
