Compiling Directives in AngularJS for Faster Page Loading

I'm currently experiencing performance issues in my Angular application. The root cause seems to be the excessive use of a directive on a single page. Unfortunately, I don't have the time to break down this page into multiple sections.

I am seeking a server-side solution (using .NET) that would allow us to pre-compile and pre-link directives to DOM elements within the template before serving the page to the client.

An alternative approach could involve pre-compiling and pre-linking the directives asynchronously on the client side while multitasking.

<my-directive></my-directive> <!-- 1000 instances within a single page -->

Thank you.

<label class="checkbox" ng-hide="ctrl.shouldHide()">
    <input type="checkbox" id="{{fieldId}}" ng-true-value="{{ctrl.valueId}}" ng-model="collection[vhFieldId]" />{{ ctrl.questionText }}
</label>

Answer №1

On the server side, it is not possible to "pre-compile and pre-link directive to DOM elements" since there is no DOM available and Angular is designed as a client-side technology.

One potential solution could be improving the implementation of the Directive so that it only needs to parse the template once and link each instance separately. This approach assumes that the performance issues are specifically related to this particular directive.

Performance bottlenecks can stem from various sources, and sometimes even simple optimizations like setting a minimum height for a directive can make a significant difference by preventing page reflows.

If you require specific assistance, sharing some code would be necessary to provide accurate help.
