dependency-injection Why do we have Dependency Injection in web development An in-depth look at why and how we implemented Dependency Injection (IoC) Container in ag-Grid. In the article I also explore the benefits DI brings in web development.
indepth.dev Connecting the dots: where hard work and dreams can lead you This is the story behind AngularInDepth and inDepth.dev. It recounts obstacles I’ve gone through, emotions I had to face, people who helped me and lessons I’ve learned along the way.
react In-depth explanation of state and props update in React This article uses a basic setup with a parent and children components to demonstrate internal processes in Fiber architecture React relies on to propagate props to child components.
angular A gentle introduction into change detection in Angular This article describes the use case that results into common ExpressionChangedAfterItHasBeenCheckedError and uses it to explore change detection mechanism and related internal implementation details in depth.
react Inside Fiber: in-depth overview of the new reconciliation algorithm in React Dive deep into React's new architecture called Fiber and learn about two main phases of the new reconciliation algorithm. We'll take a detailed look at how React updates state and props and processes children.
angular The difference between NgDoCheck and AsyncPipe in OnPush components This article uses NgDoCheck and AsyncPipe to dive deep into manual control of change detection in Angular and explains what effect each method can have on performance.
angular What every front-end developer should know about change detection in Angular and React Dive into change detection by learning the problems it solves and studying basic implementation with browser API. Then go through implementation details of change detection in Angular and React for complete understanding.
react The how and why on React’s usage of linked list in Fiber to walk the component’s tree This article explores the main the work loop in React’s new reconciler implementation called Fiber. It compares and explains the differences between browser's call stack and the implementation of the stack in React's Fiber architecture.
react Practical application of reverse-engineering guidelines and principles This article demonstrates on practice how to apply guidelines and principles of successful reverse-engineering to break down and understand React's fiber functionality from the ground up.
engineering Level Up Your Reverse Engineering Skills This article explains the reasons to start reading sources. It describes the knowledge and tools you need to do it successfully. And it also outlines a structured process to start reverse-engineering.
angular A curious case of the @Host decorator and Element Injectors in Angular This article dives deep into mechanics of @Host decorator in Angular. It introduces rarely seen notion of Element Injector and shows how it's used alongside the decorator to retrieve dependencies.
angular Ivy engine in Angular: first in-depth look at compilation, runtime and change detection This article discusses locality and tree shaking as a driving factors for the introduction of Ivy. It then continues to shed some light on the new runtime, compilation and change detection processes.
angular Working with DOM in Angular: unexpected consequences and optimization techniques This article explains a clever optimization techniques that could be applied to scenarios where ngFor is commonly used. You'll learn what is an embedded view and how to re-use it instead of destroying on each iteration.
angular Insider’s guide into interceptors and HttpClient mechanics in Angular Dive deep into internals of the HttpClient's interceptors mechanism. We'll build middleware chain for interceptors from the ground up and explore observable stream of HttpEvents and the need for immutability.
angular He who thinks change detection is depth-first and he who thinks it’s breadth-first are both usually right Do you know if Angular first checks siblings of the current component (breadth-first) or its children (depth-first)? This article demonstrates that the answer depends on what operations of change detection you consider.
rxjs Learn to combine RxJs sequences with super intuitive interactive diagrams In this article you'll find dynamic visual explanations for the most popular RxJS combination operators such as mergeMap, forkJoin and others. The article also describes use cases and termination conditions for each operator.
javascript Here is what you need to know about JavaScript’s Number type In this article I'll explain in great detail why 0.1+0.2 IS NOT equal to 0.3. We'll dive into the mechanics of floating points, explore how numbers are stored according to IEEE754 and learn some binary math.
angular Do you really know what unidirectional data flow means in Angular This article explains the essence of unidirectional data flow in view layer in Angular. It also describes the difference between unidirectional data flow in service and view layers.
angular Do you still think that NgZone (zone.js) is required for change detection in Angular? This article explains why and how Angular implements NgZone over zone.js library. Read to learn how the framework can be used completely without zone.js and when automatic change detection can fail.
angular These 5 articles will make you an Angular Change Detection expert This article is a list of articles related to change detection that you need to read to become an expert in change detection. It also offers an extra list of articles aimed at dispelling common confusions.
