I\'ve recently began learning AngularJs for web development and am loving it so far. However, I\'m not so sure about having hashtags withing the link when routing between views.
When I remove the hashtag, the reload the page and gets 404 error
That's because in your server side code you are probably not handling a request like "www.sampledomain.com/orders/450"
You can have your server-side code handle this request by either returning a redirect to the new URL ("www.sampledomain.com/#/orders/450") or just return the correct HTML directly. The "right" solution will depend on your needs.
