Overuse of $scope.$apply() degrading performance
In AngularJS, $scope.$apply() is a crucial mechanism that synchronizes the model and view, but excessive or improper use can degrade performance significantly. In this guide, we will explore: 1. Understanding….
[$rootScope:infdig] Infinite digest cycle detected
The error [$rootScope:infdig] Infinite digest cycle detected in AngularJS occurs when the AngularJS $digest cycle goes into an infinite loop. This happens when Angular’s change detection mechanism continuously re-evaluates the….
Debugging slow $digest cycles in AngularJS
In AngularJS applications, the $digest cycle is the process through which the framework checks for changes in the model and updates the view accordingly. It is crucial to the functioning….
Reducing memory leaks in AngularJS
Memory leaks are a common issue in long-running web applications, and AngularJS is no exception. A memory leak occurs when your application fails to release unused memory, leading to slow….
Handling asynchronous operations in unit tests
Asynchronous operations, such as HTTP requests, timers, and promises, are common in AngularJS applications. Testing these operations requires special handling to ensure test reliability. In this guide, we will cover:….
Using $timeout vs $interval inside services
AngularJS provides two built-in services, $timeout and $interval, for handling asynchronous operations similar to JavaScript’s setTimeout() and setInterval(). However, they integrate seamlessly with AngularJS’s digest cycle, ensuring updates are reflected….
How to use $destroy to clean up scope watchers?
What is $destroy? In AngularJS, the $destroy event is triggered when a scope is about to be removed (such as when navigating away from a page or removing a directive/component)…..
How $timeout and $interval work internally?
1. $timeout – Delayed Execution Syntax $timeout(function () { // Code to execute after delay}, delay, invokeApply); Example var app = angular.module(“myApp”, []);app.controller(“MainController”, function ($scope, $timeout) { $scope.message = “Before….
Handling memory leaks in AngularJS applications
Memory leaks in AngularJS applications can lead to performance degradation, increased memory consumption, and eventual crashes if not handled properly. This guide explains common causes of memory leaks, how to….
