海外TECH	DEV Community	What is side-effect in ReactJS and how to handle it?	https://dev.to/hellonehha/what-is-side-effect-in-reactjs-and-how-to-handle-it-39j8	What is side effect in ReactJS and how to handle it What is side EffectsReactJS is a UI library It s job is to render the UI and update it on user s interaction or events Eg if a user has clicked on a button then update the UI accordingly However there are many events which doesn t require any user s interaction or event Eg API data on load of application a user has logged in and we want to keep the users information and update the themes or other information Such requirements which doesn t need any user events or interaction is known as side effects in ReactJSWhy we need side effectsThere are a lot more operations in ReactJS which won t require user s events interactions but they are crucial to do the application work what is useEffect hookuseEffect is a hook by ReactJS and it allows us to handle such side effects in the react component It give us the correct way to handle the side effects in ReactJS code Loved this blog I have created a video on the same topic and in Hindi Learn useEffect in less than mins syntax of useEffect useEffect gt useEffect has parts method Here we will write our side effect codedependencies Dependencies array is a place where we declare dependencies and which will decide when useEffect should executeuseEffect amp dependency arrayuseEffect also works as the lifecycle hook in ReactJS This would depends on the dependency array Omit dependency array useEffect gt console log I am running This will run every time the component will re render and st time too This is componentDidMount and componentDidUpdate lifecycle hooks We should keep those side effects here which you want every time when the component is re rendering Blank dependency array useEffect gt console log I am running This will run only once at the initial mount of the component and after that it won t run You can have those side effects which you only want at the first time of mounting of your component Eg API request Value in dependency Array useEffect gt console log I am running count Here we have added a state in the dependency array This will make the useEffect to run once at the load time and then whenever the state count will change This will act as the componentDidUpdate and componentDidMount cleanupIf we need to do any cleanup of side effect before the unmounting and component re render before the component re render due to change in the state we can use the useEffect to do the same Please remember this is optional useEffect gt console log I am running return gt your clean up code count Happy Learning	2023-08-16 08:36:28
海外TECH	DEV Community	Git Tags Continued - Share, Delete and Checkout	https://dev.to/ello/git-tags-continued-share-delete-and-checkout-4p0n	Git Tags Continued Share Delete and CheckoutIn the previous post introducing Git tags we learnt what Git tags are how they are created and how we can view the existing tags By default when we run git push Git does not push the tags you have created to the remote server eg Github We need to be explicit in our intention when we want to push the tags to the remote server This post will be a continuation of the previous post discussing on the following points How to push tags to a remote serverHow to delete tags locally and in the remote server Create branches based off a tag How to push tags to a remote serverAs already mentioned merely running git push won t push the tags In order to push tags to the remote server we need to use the tags flag Hence the command would be git push tags In case you want to push to a different origingit push lt remote gt tagsUsing the tags flag will push both annotated and lightweight tags If you want to push the annotated tags only then you can use the follow tags flag instead There is no way to push just the lightweight tags How to delete a tagThe command to delete a tag in your local Git repository is git tag d lt tagname gt Deleting the tag in the remote serverIf the tag has been pushed to the remote server before deleting it in the local Git repository you need to run another explicit command to delete the tag from the remote server too The command is git push lt remote gt delete lt tagname gt Examplegit push origin delete v There is another way to delete a tag in the remote server The command is git push lt remote gt refs tags lt tagname gt The explanation of this command is Push the part before the colon to the remote tag named lt tagname gt In this case the part before the colon is null How to create a branch based off a tagThe general command to create a branch is git checkout b lt newBranch gt lt reference gt where reference can be any valid Git object Using this command a new branch based off a tag can be created using git checkout b lt newBranch gt lt tagname gt If you are looking to just explore the code that is versioned by the tag you can also directly checkout the tag using git checkout lt tagname gt Using this command puts your repository in detached HEAD state You can use the link provided to learn more about it I will also be exploring it in a future post of mine TL DR of detached HEAD In detached HEAD if you make some changes and commit them the changes will not belong to any branch and will be lost The only way to reach the commit would be by using its commit hash Final wordsMy hope is that by now you are well equipped with dealing with the basics of Git tags and are ready to tackle any new concepts that are thrown your way Again I also recommend reading my first post on Git tags References	2023-08-16 08:22:00
海外TECH	DEV Community	System Design: A Guide for Beginners	https://dev.to/anilkaundal/system-design-a-guide-for-beginners-346a	System Design A Guide for BeginnersSystem design is the process of defining the architecture components and interactions of a system to meet the needs of its users It is a complex and challenging topic but it is also incredibly rewarding This guide offers insights into designing systems that can handle varying workloads while maintaining performance and stability Strategic Decision MakingIn system design informed decision making is essential Like an architect selecting materials for a building s foundation you choose components that ensure stability and efficiency Fundamental Steps From Concept to CreationDefining System Scope The initial step involves outlining the system s purpose and understanding user needs Envision a blueprint before construction begins Determine the traffic and data constraints that will define the system s capacity to perform under varying loads High Level Architecture This stage is akin to creating an abstract blueprint of the system Imagine it as an architectural sketch that outlines the crucial components and their interactions setting the stage for the subsequent detailed design phases Component Level Design Comparable to designing intricate machinery this phase involves breaking down the system into modular components Each component has specific responsibilities and interfaces just like gears in a complex mechanism Identifying Bottlenecks Similar to anticipating traffic bottlenecks in a city system design necessitates identifying potential performance bottlenecks This might involve load balancers distributing traffic or databases requiring optimized caching strategies Scaling Strategies Scaling a system is akin to expanding a city to accommodate growth Vertical scaling adds resources to existing entities while horizontal scaling introduces new entities to share the load The decision depends on the system s nature and demands Scaling Strategies Vertical vs HorizontalVertical scaling Vertical scaling is the process of increasing the capacity of a single server or VM This can be done by adding more CPU cores RAM or storage Vertical scaling is a good option for systems with predictable workloads and limited budget Horizontal scaling Horizontal scaling is the process of adding more servers or VMs to a system This can be done by replicating the existing servers or by adding new servers Horizontal scaling is a good option for systems with unpredictable workloads and high demand Caching Accelerating System PerformanceCaching is a technique for storing frequently accessed data in memory This can significantly improve system performance by reducing the number of database queries and disk reads There are two main types of caching In memory caching This involves storing data in the memory of the server or application Disk caching This involves storing data on disk In memory caching is generally faster than disk caching but it requires more memory Disk caching is slower than in memory caching but it can store more data Load Balancing Efficient Resource DistributionLoad balancing ️is a technique for distributing traffic across multiple servers or VMs This can help to improve system performance and reliability by preventing any single server from becoming overloaded There are two main types of load balancing Round robin This is the simplest type of load balancing It distributes traffic evenly across all servers or VMs Weighted round robin This type of load balancing assigns weights to each server or VM so that more traffic is sent to servers with higher weights Other types of load balancing include Least connection This type of load balancing sends traffic to the server with the fewest active connections Least response time This type of load balancing sends traffic to the server with the lowest response time Sticky sessions This type of load balancing keeps users connected to the same server for the duration of their session The choice of load balancing algorithm depends on the specific needs of the system For example round robin load balancing is a good option for systems with unpredictable workloads while least connection load balancing is a good option for systems with high spikes in traffic In addition to the type of load balancing algorithm there are other factors to consider when designing a load balancing solution such as the number of servers or VMs to use the location of the servers or VMs and the type of network Database Replication and PartitioningDatabase replication mirrors the concept of sharing information between distributed teams Meanwhile partitioning divides data into manageable chunks facilitating efficient retrieval and storage It s akin to categorizing a vast library for ease of access Map Reduce Processing Data IntelligentlyMap reduce is a programming model for processing large datasets It is a popular choice for systems that need to process large amounts of data in parallel The map reduce programming model consists of two steps The map step The map step is responsible for breaking the data down into smaller chunks The reduce step The reduce step is responsible for aggregating the data from the map step Map reduce is a powerful tool for processing large datasets It is used by many popular systems such as Hadoop and Hive Platform Layer A Robust FoundationThe platform layer is the foundation of a system It provides the basic services that are needed by other components of the system The platform layer typically includes services such as Operating system The operating system provides the basic functionality for the system such as process management and memory management Database The database stores the data for the system Web server The web server serves web pages to users Application server The application server runs the applications for the system The platform layer is important for system performance and reliability By carefully designing the platform layer you can ensure that the system is able to handle the load and that it is resistant to failures Concurrency and NetworkingConcurrency and networking are two important aspects of system design Concurrency is the ability of multiple tasks to run simultaneously This is important for systems that need to handle a lot of traffic or requests Networking is the process of sending and receiving data between computers This is essential for systems that need to communicate with each other Web Applications Where Form Meets FunctionWeb applications are a type of system that is becoming increasingly popular They are used for a variety of purposes such as e commerce social media and content management Web application architecture is the process of designing a web application to meet its requirements It is important to consider factors such as scalability reliability and security when designing a web application architecture Resources for Further ExplorationScalable System Design PatternsIntroduction to Architecting Systems for ScaleMastering system design requires understanding these principles and techniques By applying them you can create efficient scalable systems that stand as a testament to your skill and ingenuity I hope you found this blog post

海外TECH	DEV Community	GDScript Code Ordering	https://dev.to/godot/gdscript-code-ordering-5d9f	GDScript Code OrderingGDScript Code Ordering Best Practices for Arranging Your Code ElementsWhen it comes to writing clean and organized GDScript code the ordering of code elements plays an essential role in enhancing readability and maintainability In this post we ll explore best practices for ordering different code elements within your GDScript files Introduction to Code OrderingCode ordering refers to the systematic arrangement of different code elements within your GDScript files Having a consistent and logical order makes it easier for developers to quickly grasp the structure of your code and find specific elements While there is no strict rule for code ordering following some common conventions will lead to well organized and easily maintainable code Recommended Code Element OrderingBelow we present a recommended order for organizing code elements within your GDScript files Remember that these conventions are guidelines and you can adjust them to suit your project s needs and team preferences DeclarationBegin by listing all necessary class declaration statements at the top of your GDScript file These statements help you access external classes and modules within your script class name Player extends CharacterBodyDIf your script is a tool ie running in the Editor make sure you put the annotation at the very top of the code toolclass name Player extends CharacterBodyDYou might need to save and reopen the scenes script for it to take effect SignalsAfter that define the signals that your script emits Signals are custom events that allow communication between nodes therefore it is beneficial to have it right up above class name Player extends CharacterBodyDsignal health depletedsignal player moved Vector EnumsIf your script uses enums you can do so after the signals Enums are user defined sets of named constants and are often used to represent different states or options enum GameState MENU PLAY PAUSE enum Direction UP DOWN LEFT RIGHT ConstantsNext define any constants that your script requires Constants are values that do not change during runtime and are better suited for this early section of your script const MAX SCORE int const PLAYER SPEED float Class VariablesNow organize your class variables Group them into different subsections based on their purposes Export VariablesExport variables come first as they allow you to expose certain variables in the Inspector This makes them easily accessible and configurable from the Godot editor Good export variables ordering exampleclass name Player extends CharacterBodyD export var player name String Player export var player health int Regular VariablesThen list your regular class variables public and private You can mark a variable as a private by prefixing them with underscore Doing so will hide your variable from showing inside the built in IDE Documentation class name Player extends CharacterBodyDvar score int var is gameover bool false private will not appear on docs Onready VariablesOnready variables come last after every other variables They represent references to nodes that you need early on right after initialization class name Player extends CharacterBodyD onready var player sprite Sprite PlayerSprite onready var enemy spawner EnemySpawner EnemySpawner Constructor and InitializationAfter the class variables you can include the constructor also known as the init method if you need to initialize any variables Note that overriding the init ready enter tree or other built in virtual function is optional Good constructor and initialization ordering exampleclass name Player extends CharacterBodyD Constructorfunc init gt void player additem Item SWORD player additem Item SHIELD func enter tree gt void var parent name get parent name print Parented to parent name func ready gt void sync textures sync animations Public MethodsFinally place your class public methods Group them based on their purposes or relevance to specific aspects of your script Good class methods ordering exampleclass name Player extends CharacterBodyD Initialization methodsfunc ready gt void pass Player movement related methodsfunc move player gt void pass Player combat related methodsfunc damage player gt void pass Private MethodsMethods of your class can be marked as private by prefixing them with underscore Private variables and private methods that are prefixed by will not appear when you open Search Help F of this particular class func internal check internal check will not appear in IDE Help pass Code Organization in FunctionsWithin your class methods aim for consistent code organization to maintain readability ArgumentsList function arguments in a logical order with required arguments first and optional arguments last Good function arguments ordering examplefunc move player direction Vector speed float pass Local VariablesDeclare local variables at the beginning of the function before using them Good local variables ordering examplefunc calculate score score value int gt int var bonus score int return score value bonus score Function LogicOrganize the logic of your functions in a way that is clear and easy to follow Consider using comments to explain complex sections Best code is the one that doesn t require comments and innately self explanatory func is game over gt bool if player health lt and player lives lt return true else return false ExampleNow with all that said and done here is the final snippet to sum it all up See it in action Note The examples and conventions provided in this post are intended as guidelines Feel free to tailor them to your specific needs and preferences Consistency is key tool This is the Player class representing the player character in the game class name Player extends CharacterBodyD Signalssignal player hitsignal player jump Enumsenum

Code here will be executed when the node enters the scene tree pass Built in virtual ready methodfunc ready Code here will be executed once when the node is added to the scene and ready pass Remaining built in virtual methodsfunc process delta float Code here will be executed every frame if the node is added to the scene and ready pass Public methodsfunc take damage damage amount int if not is invincible player health damage amount if player health lt emit signal player hit func jump if is on floor player state PlayerState JUMPING apply impulse Vector UP jump power emit signal player jump Private methodsfunc on invincibility timer timeout is invincible false Subclasses Add any subclasses here if applicable SummaryFollowing an organized code ordering is crucial for creating clean maintainable and readable GDScript code By adopting a consistent approach to arranging your code elements you can improve collaboration within your development team and make it easier for other developers to understand and contribute to your projects Remember that the conventions provided in this post are recommendations not strict rules Feel free to adapt them to your project s needs and your team s preferences The key is to maintain consistency throughout your codebase making it easier for everyone to work together efficiently Happy coding and may your GDScript projects shine with well organized and easily understandable code	2023-08-16 08:07:37
