AngularJS Question

loopback angular 404 on refresh page

I have create an application with loopback and angular but i have a problem. When i refresh the browser loopback give me a 404 url not Found.

Added base tag to index.html

<base href="/"/>

Set middlelware.json properly to serve static content:

"files": {
"loopback#static": {
"params": "$!../client"

Set HTML5 mode in angular router (I'm using ui-router)


I have yet deleted root.js from the project.

What i'm doing wrong? Thanks in advance

When you have enabled html5 mode/ push state mode ON in angularjs, this is a common scenario which your server should handle. If I understood your problem correctly, server returns 404 when you refresh the page which otherwise render fine if navigated from landing page. Let me know if this is the scenario:

  • Angular app lands into Home screen, say your_domain/
  • Navigate to some other page - your_domain/somepage (which will be your_domain/#somepage in case of hash bang mode)
  • Refresh the page -> throws 404

If the scenario which you face is like given above, then this is what happens:

  • Loads the home page -> angular is bootstraped and routing is set up
  • Navigates to "somepage" -> angular route handles this and show "somepage"
  • Refresh the page -> request hits the server and requests for your_domain/somepage - which is not available in server
  • server returns 404

How to handle this? Do Url rewrite back to your_domain/ from server in case of 404. This will bootstrap the angular app and angular route will handle the request
