prioritizing the loading of the header in an Angular application before proceeding to load the main content

Question

prioritizing the loading of the header in an Angular application before proceeding to load the main content

My website has a basic layout shown below:

|-------------------|
|   HEADER          |
|___________________|

|------||-----------|
| side ||  Main     |
| bar  ||  Content  |
|      ||           |
|------||------------

For routing and states, I am using Angular UI-router with resolvers to load data for specific states. Upon navigating to a state, all of the components appear at once after loading their respective data. Typically, the header and sidebar load quickly, while the main content takes longer.

I am wondering if it is possible to display them in a sequential order:

Header
Sidebar
Main Content

Additionally, it would be ideal if the main content could include a loader as well. Initially, I considered adding code in the controller instead of using a resolver, but I believe the resolver approach is more elegant.

Answer №1

One useful tool in Angular is the defer feature, which allows you to create promises and better organize your code. By using angular defer, you can execute methods after specific events have occurred.

Refer to the official documentation for more information.

Here's an example to demonstrate how it works:

var showHeader = function() {
  var defer = $q.defer();
     // Perform necessary tasks
     // Display the header
  defer.resolve();
  return defer.promise;
}
showHeader().then(function(){
    // Show the main content and sidebar  
});
