The News page uses 4 unique Vue apps

Multiple apps? Huh?!

  • We‘re not an SPA, so we don‘t need to manage the entire application‘s state from one single source
     
  • Unlike React, Vue has a clear distinction between what‘s an app and what‘s a component
     
  • Each app is restricted in its scope. It only has the exact template and data that it needs
     
  • Each page of the website can be completely different
     
  • Our resilience to failure is much greater with everything independent
