Why Does AngularJS Use Hashtags (#) in URLs and How Can I Remove Them?

AngularJS Routing: Understanding Hashtags (#) in URLs

In AngularJS, routing plays a crucial role in managing the application's navigation. However, beginners often encounter the issue of URLs containing a hash (#) sign, such as app/#/test instead of app/test. This can be confusing and raises questions about its necessity.

Why AngularJS Adds Hashtags (#) to URLs

AngularJS utilizes the hashtag (#) for non-HTML5 browsers. These browsers lack support for client-side routing, which means they would execute an HTTP request to the server for any URL changes. By adding the hashtag, AngularJS prevents this from happening, allowing it to handle routing on the client side without interrupting server communication.

Options to Avoid Hashtags (#) in URLs

If your application requires support for HTML5 browsers, you can instruct AngularJS to use the HTML5 strategy for routing. To do this, execute $locationProvider.html5Mode(true) in your application's configuration.

Browser Compatibility for HTML5 Strategy

It's important to note that not all browsers support the HTML5 strategy. You can refer to the following link for a detailed list of browsers that support it: http://caniuse.com/#feat=history
