AngularJS is made to rearrange the complex process of building and overseeing JavaScript applications. In view of the Model-View-Controller, or MVC, programming structure, AngularJS is particularly valuable for making single page web apps. Today, online businesses are enormously affected by the performance of web technologies that they use for their respective tasks. Henceforth, it winds up important to dive into the majority of the elements that are harming their business growth.

AngularJS can rapidly be added to any HTML page with a straightforward tag. In case you’re asking why you have a couple of slow pages, here are a few hints to accelerate your code.

AngularJS Optimization Tips

  1. Batarang Tool to Benchmark Watchers
    • Batarang is an awesome dev tool from the AngularJS developer that brings down your debugging efforts. In spite of the fact that it has numerous new features, some of them enable you to profile and track the execution of your AngularJS performance. In addition, the watch tree figures out which extensions are not destroyed as it is by all accounts if there is an increase in the memory.
  2. Chrome Dev Tool Profiler to Identify Performance Bottlenecks
    • This one is a helpful device that gives you the alternative to choose which profile type you need to make. Take Heap Snapshot, Record Allocation Timeline, and Record Allocation Profile are utilized for memory profiling. After this performance improvement, your app will complete in under two seconds and clients can freely connect with it then.
  3. Limit your watchers
    • Talking about which, whenever you introduce data-bindings, you make more $scopes and $$watchers, which drags out the digest cycle. Excessively numerous $$watchers can cause lag, so restrain their utilization as much as possible.
  4. Utilize scope.$evalAsync
    • On the off chance that you endeavor to manually initiate the digest cycle while it’s now running, you could get an error. To keep this from happening, utilize scope.$evalAsync rather than $apply when you have to start the digest cycle. It lines up operations to be executed toward the finish of the present cycle without setting off another one.
  5. Limit DOM access
    • Getting to the DOM can get costly, so keep your DOM trees little. Try not to change the DOM if you can encourage it, and don’t set any inline styles to maintain a strategic distance from JavaScript reflow.
  6. Disable debug data
    • Tools like Protractor and Batarang think about the data about binding and scopes that AngularJS connects to DOM components. In this manner, when you’re finished troubleshooting, disable the additional data so that it doesn’t drag your application down.
  7. Utilize ng-if or ng-switch instead of ng-show
    • The directive ng-show essentially flips the CSS show on or off for a predefined element.
    • To remove a component from the DOM, you should utilize ng-if or ng-switch.
  8. Utilize $cacheFactory
    • On the off chance that you wish to store information that you may simply get to recalculate later, utilize the $cacheFactory directive. It works like every alternative memoization methodology.
  9. Utilize console.time
    • If you’re having issues troubleshooting, console. time (Chrome DevTools) is a magnificent tool for estimating execution times and other performance benchmarks.
  10. Utilize $watchCollection instead of $watch (with a 3rd parameter)
    • $watch with just 2 parameters, is fast. In any case, Angular supports a 3rd parameter to this capacity, that can resemble this: $watch(‘value’, function(){}, true). It tells Angular to perform deep checking, assuming to check each property of the object, that may be terribly costly.
    • To address this performance issue, angular included $watchCollection(‘value’, function(){}). $watchColleciton acts relatively like $watch with a 3rd parameter, aside from it just checks the primary layer of the object’s properties, along these lines significantly enhancing the performance.
  11. Pagination or infinite scroll
    • When in doubt, you can bring down the number of components that get circled over by actualizing pagination or infinite scroll. AngularJS even has an order called ngInfiniteScroll for that reason.

You can find a variety of tools devoted to enhancing the performance and testing of AngularJS apps. Here are a few of the best options:

  • Protractor
  • WebDriverIO
  • NightwatchJS
  • TestingWhiz
  • Batarang


As we have seen, web development is changing quickly because of the presence of numerous new and refreshed JavaScript frameworks. To get the most extreme advantages from these frameworks, you should continue optimizing performance on regular basis.

In spite of the fact that there are many JavaScript frameworks nowadays, AngularJS remains a most loved for some, so it won’t go anywhere anytime in the near future. To get the most out of your applications, you should make AngularJS optimization a customary habit. Adjusting your application’s performance may enable you to give more content while utilizing less code, which arranges for resources that could be better spent somewhere else.
