Encountered an error with the Angular 1 component router: Unable to access property 'startsWith' as it is undefined

I've been utilizing the Angular 1 component router and encountering some strange issues. Everything works perfectly when I run the website locally, but as soon as I try to access it from another PC, I'm hit with a JavaScript error.

It keeps throwing an error saying 'Cannot read property 'startsWith' of undefined'

I've attempted to access the website from multiple PCs using various browsers such as IE, Chrome, and Safari. The results vary - sometimes it works fine, while other times it displays the JavaScript error mentioned above.

If anyone has any advice or suggestions, please let me know!

Answer №1

The problem stemmed from the base href URL.

I configured the location provider to use HTML5 mode and added the base href to the page as shown below:

<base href="/Application/">

When I accessed the application, I encountered a JavaScript error; however, when I accessed the Application, it worked as intended. This inconsistency made it difficult for me to identify the issue since I overlooked the importance of the base URL.

Therefore, the problem did not lie with the component router but rather with how the location provider interpreted the base href.

Although seemingly trivial, the fact that the base href is case sensitive and cannot be configured to be case insensitive caused frustration.

Remember to pay attention to this detail in the future.
