I am using Angular 2.0.0-alpha.30 version. When redirect to a different route, then refresh the browser , its showing Cannot GET /route.
Can you help me with figuring why this error happened.
The error you are seeing is because you are requesting http://localhost/route which doesn't exist. According to Simon.
When using html5 routing you need to map all routes in your app(currently 404) to index.html in your server side. Here are some options for you:
using live-server: https://www.npmjs.com/package/live-server
$live-server --entry-file=index.html`
using nginx: http://nginx.org/en/docs/beginners_guide.html
error_page 404 /index.html
Tomcat - configuration of web.xml. From Kunin's comment
<error-page>
<error-code>404</error-code>
<location>/index.html</location>
</error-page>
