TLDR

Eliminate blinks with ng-cloak by putting this CSS snippet in your HTML <head>:

<style> .ng-cloak { display: none !important; } /* No peeks here, just hide it */ </style>

Include AngularJS early in your code for ng-cloak to jump into action. Also, take a break from the curly-brace syntax to too prevent undesirable delays. Use ng-bind for a more immediate control on visibility:

<!-- It's not what you show, it's how you show it! --> <span ng-bind="yourModel"></span>

Style it right

Maintain better consistency and organization by incorporating the CSS rules for ng-cloak within an external stylesheet. But, CSS won't save your day when Bootstrap steps in! So be sure to double check if any styles from the framework are overriding your ng-cloak styles!

Timing is everything

Engage ng-cloak in action swiftly by placing your AngularJs script at the head of your page. It's all about being early to rise for optimal performance!

Explore your options

Ditch ngShow and venture out. Try using ngIf for conditional rendering, it may just be the effective alternative you never thought you needed.

Pre-compilation is key

Keep flickering at bay. Use ng-include to compile templates before DOM insertion. The key is to ensure readiness before visibility!

The other side of the coin

Meet the alternatives of ng-bind and ng-bindTemplate. Say goodbye to the CSS dependency and inconsistent behaviors across browsers!

Resolve the discord

Ever noticed that Firefox acts up with ng-cloak and ng-show? Well, a quick fox fix will be to switch to display: none in your CSS!

Get your script tags in order!

If it's the head you choose to place your AngularJS script, opt for the defer attribute. This ensures your script is executed after parsing, just in time for the DOMContentLoaded event!

Overrule with care

When you're juggling between frameworks and custom CSS, you must watch out for rule specificity. Your emergency !important might just need to come into action to override those pesky styles.

Make room for precompilation

Why wait when you can have a fully cooked DOM to start with? Tuning your AngularJS to server-side rendering or precompilation means no more waiting for an appetizing application!
