海外TECH	DEV Community	Understanding the Differences Between HTTP and HTTPS	https://dev.to/haszankauna/understanding-the-differences-between-http-and-https-3155	Understanding the Differences Between HTTP and HTTPSAs the world becomes more connected the need for secure communication between web servers and clients grows The Hypertext Transfer Protocol HTTP and the Hypertext Transfer Protocol Secure HTTPS are two widely used protocols for web communication In this article we ll look at the differences between HTTP and HTTPS as well as why HTTPS is becoming the preferred option for web developers and users What is HTTP HTTP is a protocol that governs data transmission over the internet It serves as the foundation of the World Wide Web allowing data to be transmitted between a web server and a client usually a web browser Because HTTP is a text based protocol the data being transmitted is in human readable format HTTP is a request response protocol that runs on top of the Transmission Control Protocol TCP An HTTP request message is sent when a client web browser sends a request to a server The server then sends an HTTP response message in response These messages include information such as the request type headers and body if applicable What is HTTPS HTTPS is an encrypted version of HTTP It encrypts data transmitted between a web server and a client by combining HTTP and Secure Sockets Layer SSL or Transport Layer Security TLS protocols HTTPS encryption is used to protect sensitive data such as passwords credit card numbers and other personal information HTTPS works similarly to HTTP with the main difference being that the data sent between the server and client is encrypted This encryption aids in preventing unauthorized access to sensitive data The Differences Between HTTP and HTTPS EncryptionEncryption is one of the primary distinctions between HTTP and HTTPS HTTPS uses SSL or TLS to encrypt data making it far more secure than HTTP Data is encrypted before being sent over the internet when transmitted via HTTPS This encryption aids in the prevention of unauthorized access to sensitive data such as credit card numbers and passwords Certificate AuthenticationCertificate authentication is another distinction between HTTP and HTTPS When a web browser connects to a web server via HTTPS the server sends the browser a digital certificate This certificate contains server specific information including the server s public key This certificate is then used by the browser to establish a secure connection with the server Port NumberHTTP employs port whereas HTTPS employs port This means that when you visit a website via HTTP the URL begins with http whereas URLs via HTTPS begin with https PerformanceBecause of the additional overhead of encrypting and decrypting data HTTPS is generally slower than HTTP However advances in the SSL and TLS protocols have significantly reduced this overhead allowing HTTPS to be much faster than it was previously ConclusionFinally HTTPS is quickly becoming the preferred protocol among web developers and users It provides more security than HTTP making it an excellent choice for websites that send sensitive data While HTTPS is generally slower than HTTP the difference in performance is negligible making it a viable option for all types of websites As a developer you must understand the distinctions between HTTP and HTTPS and use HTTPS whenever possible You can help to secure your users data and build trust with your audience by using HTTPS	2023-02-25 16:18:51
海外TECH	DEV Community	Building Dynamic User Interfaces with React and React-Router	https://dev.to/haszankauna/building-dynamic-user-interfaces-with-react-and-react-router-2gcp	Building Dynamic User Interfaces with React and React RouterReact is a well known JavaScript library used to create dynamic and interactive user interfaces React Router is a library used in React applications to handle client side routing We will learn how to use React Router to create dynamic user interfaces including handling nested routes authentication and page transitions in this article PrerequisitesBefore delving into the details of React Router it s important to first understand React and JavaScript If you re new to React read the official React documentation or enroll in a React course Knowledge of HTML and CSS is also advantageous Setting up React RouterTo begin using React Router we must first install it You can install it with npm the Node js package manager npm install react router domOnce installed we can use the following line to import React Router into our code import BrowserRouter as Router Route Switch from react router dom Creating RoutesRoutes are the foundation of React Router They are in charge of mapping URLs to components React Router includes a number of route creation components Route Switch and Link are the most commonly used A route component is used to specify a path It requires two parameters path and component path is the URL that should be matched by the route When the URL matches the path component is the React component that should be rendered lt Route path about component About gt A Switch component wraps multiple Route components Only the first Route that matches the current URL is rendered This prevents more than one component from being rendered at the same time lt Switch gt lt Route path exact component Home gt lt Route path about component About gt lt Route path contact component Contact gt lt Switch gt The link component is used to create links to various routes It requires only one parameter to which is the URL to which the link should point lt Link to about gt About lt Link gt Handling Nested RoutesRoutes that are rendered within another route are referred to as nested routes They come in handy when creating complex user interfaces React Router makes handling nested routes simple and intuitive To create nested routes we must first define the parent and child routes Within the parent route the child routes should be defined To render the child routes we can use the render prop lt Route path products render gt lt div gt lt h gt Products lt h gt lt Route path products id component Product gt lt div gt gt We defined a parent route products and a child route products id in the preceding example The id parameter stands in for the product ID When a user navigates to products the Product component with the ID is rendered Authentication ManagementWeb applications frequently include authentication Using the Redirect component React Router handles authentication The Redirect component is used to redirect users to another page based on specific conditions import Redirect from react router dom function PrivateRoute component Component authenticated rest return lt Route rest render props gt authenticated true lt Component props gt lt Redirect to login gt gt In the preceding example we defined a PrivateRoute component with three props component authenticated and rest component denotes the React component to be rendered authenticated is a boolean value indicating whether or not the user has been authenticated rest is a container for any additional props The Route render prop is used to render the component depending on the authentication status The Component is rendered if the user is authenticated If the user is not authenticated the Redirect component redirects the user to the login page Page TransitionsPage transitions are animations that happen when a user switches between pages The react transition group library is used by React Router to handle page transitions npm install react transition groupAfter installing the react transition group library we can import the TransitionGroup and CSSTransition components import TransitionGroup CSSTransition from react transition group To enable page transitions we can wrap our Switch component in the TransitionGroup component The CSSTransition component is used to define the animation lt TransitionGroup gt lt CSSTransition key location key classNames fade timeout gt lt Switch location location gt lt Route path exact component Home gt lt Route path about component About gt lt Route path contact component Contact gt lt Switch gt lt CSSTransition gt lt TransitionGroup gt In the preceding example we wrapped our Switch component in a TransitionGroup component CSSTransition s key prop is set to location key to ensure that the animation is triggered when the location changes To define the animation the classNames prop is set to fade The timeout prop is set to milliseconds to specify the duration of the animation ConclusionReact Router is a robust library that handles client side routing in React applications In this article we have learned how to use React Router to create dynamic user interfaces including handling nested routes authentication and page transitions We also used cutting edge technology and examples to demonstrate the concepts You can use React Router to create a unified user experience and improve the overall usability of your application	2023-02-25 16:04:15
海外TECH	DEV Community	Debugging the bug free code	https://dev.to/dhanushnehru/debugging-the-bug-free-code-5784	Debugging the bug free code IntroductionAs a programmer you might have come across the phrase bug free code This term refers to software that is free of errors glitches and other defects that can cause it to malfunction However despite the rigorous testing debugging and quality assurance practices employed by programmers it is virtually impossible to write completely bug free code In this blog post we will discuss why bug free code is a myth and provide my own example to illustrate this point As a Software DevOver the years I have developed software in various domains and it is important to understand that software development is a complex and dynamic process It involves numerous stages including planning designing coding testing debugging and deployment Each of these stages involves human intervention and as we all know humans are not perfect sometimes even AI Even the most experienced and skilled programmers can make mistakes overlook critical details or misinterpret requirements Moreover the software is often written to perform tasks in highly unpredictable environments which can make it challenging to anticipate all possible scenarios For example a program designed to operate under a certain operating system may not work properly in another environment or with a different set of hardware Similarly a program that works perfectly fine in a specific situation may fail when unexpected inputs are encountered or when requirements are added over iteration BackgroundLet s consider my example to illustrate this point I want to describe a task that happened in the initial days of my career The TechnologyThe tech I was working on was Node js and was using MongoDB a popular NoSQL database that uses ObjectIDs as the primary key for its documents While ObjectIDs are useful for uniquely identifying documents they can also lead to issues if they are not properly interpreted in code ObjectID Misinterpretation in CodeIn MongoDB an ObjectID is a byte BSON type that consists of a timestamp machine ID process ID and a random value It is designed to be globally unique making it an ideal primary key for documents in a database When querying for a document using its ObjectID in code it is important to treat the ObjectID as an object not a string If the ObjectID is treated as a string it may lead to unexpected behavior in the code For example consider the following code snippetconst objectId fdaea db collection mycollection findOne id objectId err result gt if err console error err return console log result In this code the ObjectID is treated as a string instead of an object As a result when the findOne method is called it will not find the document with the given ObjectID Initially in my code I didn t convert into an ObjectID because when the code is queried and passed to this condition it would be another object Id queried from MongoDB and it had no issues The BugThe bug arose when there was a scenario where the object id was queried from a Redis data store which is an in memory data structure where the ObjectID can be only stored as strings and it was directly passed to this query I was confused with what was happening as a few times the output came as expected when it was a direct query without involving Redis and a few times outputs were queried as null Code Logic FailureWhen the ObjectID is misinterpreted as a string it can lead to unexpected behavior in the code such as not being able to find a document or finding the wrong document This can cause the code logic to fail leading to bugs and errors in the application For example consider an e commerce application that uses MongoDB to store orders If the ObjectID is misinterpreted in the code it may lead to the application finding the wrong order or failing to find the order altogether This can result in the wrong item being shipped or the customer receiving the wrong order Debugging StrategyI put console statements on lines to debug but still was not able to figure it out Then after spending some time on it something struck me and I decided to check the type of data which is sent to the query And then identified that we need to pass it as ObjectId SolutionThe below solution worked where I would convert the string into an object id and then would pass in the queryconst objectId new ObjectId fdaea db collection mycollection findOne id objectId err result gt if err console error err return console log result Misinterpreting Mongo ObjectIDs as strings instead of objects can lead to code logic failure causing unexpected behavior in the code and leading to bugs and errors in the application When working with ObjectIDs in code it is important to treat them as objects and not as strings to ensure proper functionality and prevent errors Lesson learnedWhile it is essential to strive for bug free code it is crucial to recognize that perfection is unattainable Instead programmers should focus on writing code that is as robust reliable and flexible as possible They should also be prepared to identify diagnose and fix bugs as quickly and efficiently as possible With the right tools practices and mindset programmers can minimize the impact of bugs and deliver high quality software that meets users needs ConclusionI have faced much more bugs in my career and I would like to share a few insights which may help fellow developersReproduce the bug Try to reproduce the bug in your local environment This will help you to understand the root cause of the issue and develop a fix Debugging Use debugging tools to step through the code and identify where the bug is occurring This can help you to understand the flow of the code and identify the root cause of the issue Communication Communicate with other members of the team or the person who reported the bug This can help you to get more context and background information that may help you to find a solution more quickly Fix the root cause Don t just fix the symptoms of the bug but make sure to fix the root cause This will help to prevent similar bugs from occurring in the future Test the fix Test the fix thoroughly to ensure that it resolves the bug and doesn t introduce new issues Automated testing can be especially helpful for this Document the solution Document the solution and share it with the team This can help others who may encounter similar issues in the future Thank you so much if you have read it so far Connect with me via Twitter
