In this day and age, AngularJS is widely used as the web app framework. It is well-matched for developing the large app built to enjoy the high performance on the web. Won’t it be great if you get acquainted with proven ideas that will optimize the development of AngularJS? Are you looking for ways to enhance your Angular performance? Let’s move ahead to discuss the great ideas that will be going to enrich your project. AngularJS The good indicator of AngularJS performance is its digest cycle. Take it as a loop that verifies for changes to variables that is being examined. Your application will run in a faster way if your digestive cycle is shorter. Treat digest cycle as a loop- — You can take benefit of different binding if you are using an older version of AngularJS. The one –time binding feature was introduced in AngularJS 1.3 and is not present in Angular4.0. Try one-time binding Before the value add a double-colon. The value will work out once and then fade away from the watcher’s list. You can assign directive as an attribute, element, CSS class or comments while creating it. If you don’t require, then you can put out of action the CSS class and comment directives for performance improvement. Knock out CSS class, and comment directives- **Tight Scooping –**From time to time the garbage collector can be able to free up some memory so keep your variables scoped tightly. JavaScript By simply rewriting some of the underlying logic you can boost your application performance by employing Lodash. If you don’t find Lodash in your application then maybe you have to write everything in native JavaScript. Make use of Native JavaScript or Lodash- On a particular element, the ‘ng-show’ directive controls the CSS display property. The ‘ng-if’ directive takes away the element from DOM and as per the requirement can rebuild it. With the same performance benefits, the ‘ng-switch’ directive acts as an ‘ng-if’. ‘Ng-if’ serves you better than ‘ng-show’- - Use ‘console.time’ that serves as the great API, in case your application is fighting with debugging problems and affecting the Angular performance. Console.time for debugging issues Reduce the number of watchers to decrease the time in each digest cycle. It helps in reducing the application’s memory footprints. Minimize watchers- It will be great if you keep away from ng-repeat and build the HTML using JavaScript. To avoid ng-repeat directive is the most significant success for any app. Avoid ng-repeat- Angular perform deep checking with $watchCollection that includes 3rd parameter. It is in the form of –‘value’, function(){}, true. Practice $watchCollection- At the time of each digest cycle, the AngularJS runs DOM to identify the changes and to update values that have changed. The $filter provider lets you preprocess data before it is sent to the View that in turn save some time. Go for the $filter- Being handy tool it provides you with the choice to select which profile type you want to create. It delivers performance optimization by working on record allocation timeline, taking a heap snapshot, recording allocation profile that is used for memory profiling. In less than two seconds your app will fully render after this performance optimisation. Chrome Dev tool profiler- In case all fails, then you can avail the option to lower the number of elements that get looped over by carrying out the endless scroll. For that purpose, AngularJS holds a directive known as ngInfiniteScroll. Infinite scroll- It works as the memorisation method. So if you want to store data that you prefer to recalculate later, then draw on to $cacheFactory. Employ $cacheFactory- Keep your DOM trees small as getting into the DOM can be expensive. Better not to modify DOM in case you can help it. To avoid JavaScript reflow, it is advisable not to set any inline styles. Limit DOM access- Conclusive lines: Indeed online businesses are significantly affected by the performance of web technologies that they use for their project. The useful tips mentioned above will provide the excellent user experience. If you implement these best practices in your development process, then it will help you enhance the performance of your AngularJS application.
