"The blueprint for full-stack applications!" It’s day 14 of learning Node.js from Akshay Saini 🚀 Today, I delved into the crucial phase of planning before building a full-stack application. I explored the importance of low-level and high-level design, which serves as the foundation for structuring the entire application. Alongside that, I learned about database design, ensuring data is organized efficiently, and API design, which is key to enabling seamless communication between different parts of the application. The planning stage may not involve much coding, but it's just as essential to ensure that everything runs smoothly when development starts! #NodeJS #FullStackDevelopment #WebDevelopment #DesignPrinciples #API #DatabaseDesign #LearningJourney #NamasteNode #NorthcapUniversity #NCU

🔊 How to Manage Common States in React? 🚀 Reference 🙏 #namastereact and #namastefrontendsystemdesign by Akshay Saini 🚀 and Chirag Goel on NamasteDev.com Hey #connections, did you know React’s One-Way data flow mechanism, from Parent to Child, makes managing common states among children crucial? Here are some ways to tackle that! 👉 LocalStorage/Session Storage (Not Generally Recommended) Using browser storage can ease your problem but can also challenge your website’s performance. It’s not ideal for managing large state data. 👉 React Context API The React Context API shares variables and functions across the entire application. It’s great for managing small state data and comes out of the box, so no third-party packages are needed. 👉 Lifting the State Up + Props Drilling This can be used for siblings where the parent is the same. However, it can bloat your parent component if there are many state variables and functions. It’s not recommended if you have to prop-drill extensively. 👉 State Management Libraries Redux and Zustand are some third-party state management libraries you can incorporate into your React application for managing large state data. However, using these libraries from the beginning might be overkill for small-scale applications.

💫I just wrapped episode-6 (Exploring The World) in Namaste -React Course under the guidance of Akshay Saini 🚀 👉🏻About Monolithic and Microservices. 👉🏻useEffect () is a hook React provides us,it is a regular Javascript function. ⭐️useEffect() takes two arguments. 💫01.Callback function: Is a function that is passed as an argument to another function and is executed after some kind of event or operation completes. It’s a way to ensure that code doesn’t run before an asynchronous operation has completed. 💫02. Dependency Array: It determines when the hook should be executed or recalculated based on changes to the values listed in the array. ⭐️Shimmer UI: 👉🏻shimmer UI is a technique that shows placeholder content while data is loading,reducing wait time and keeping users engaged. 👉🏻 Use of ternary oerator in code base. #React #Webdevelopment #akshaysaini🚀

I would love to share a new learning about building custom hooks from Akshay Saini 🚀's Namate React course. Let's discuss how we should build a custom hook....🚀🚀 => while making a custom hook , first we should think that what's the contract, so here contract means what the hook takes as input and what the hook giving as output, For example , we are building a custom hook for abstracting the functionality of fetching the data of restaurantMenu , the hook name is useRestaurantMenu(). Our useRestaurantMenu() takes the resId(restaurant id) as input while calling the function and it will return the resInfo(restaurant information) as output ,so this is the contract of this hook, so it will get the resId and fetch the Data and return the resInfo back to where it is called from. And also export it because we will use it inside another file `RestaurantMenu.js` so we need to import it there.and this hook has it's own useState() and useEffect() in it. And remember we should always start hook names with the word `use`, it;s a convention in developer's world, and as hooks are actually some helper functions so put them inside `utils` folder. *Custom hook to fetch the data of restaurant menu const useRestaurantMenu = (resId) => {   //*saving the data inside a local state variable   const [resInfo, setResInfo] = useState(null);   //*fetching data   useEffect(() => {     fetchData();   }, []);   const fetchData = async () => {     const data = await fetch(MENU_API_URL + resId);     const json = await data.json();     console.log(json);     setResInfo(json);   };   //*returning restaurant information   return resInfo; }; export default useRestaurantMenu; thanks for reading #react #javascript

Thank you, Akshay Saini 🚀. Your content delivery is truly exceptional—you're like a content delivery machine ! It took 4.5 hours to cover just 42 minutes of your class ! Just Love it . ❤️ Day 1 : Introduction to Node.js Node.js : Run JavaScript Everywhere. 💪 Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser. ↔ Node.js has an event-driven architecture capable of asynchronous I/O.( None Blocking I/O ). ↔ Every Browser Run JavaScript And Every Browser Has Own JavaScript Engine. ↔ JavaScript code cannot run without a JavaScript engine. Wherever JavaScript code is executed, there is always a JavaScript engine running it. History of Nodejs : 🚀 ↔ Ryan started with the Spider-Monkey Js Engine, which is found on Firefox. but in two days he tried using v8 and never looked back. ↔ Node js is Powered / Igniting by V8 Engine behind the scene. ↔ Ryan Dahl initially worked independently on Node.js, but Joyent, a company working on a similar idea, supported his vision. They provided funding, and Dahl developed Node.js under Joyent's. ↔ The earlier name of Node.js was Web.js, but Ryan Dahl later renamed it to Node.js because it was intended to be used for more than just web servers. ↔ Ryan Dahl created Node.js to address the limitations of blocking servers like Apache HTTP Server. Node.js uses non-blocking I/O, which allows it to handle multiple requests with fewer threads ↔ In 2010, npm Was Introduced . npm is a major success for the Node.js community. Node.js might not  become very popular without npm. ↔ Node.js was first released in 2009, initially supporting Linux and macOS. it was Written In : JavaScript, C++, Python, C. ↔ In 2011, Node.js gained Windows support through collaboration between Joyent and Microsoft. ↔ In 2012, Ryan Dahl left the Node.js project. He was an employee of Joyent, but he was not directly responsible for the ongoing development of Node.js. ↔ In the same year, Isaac Z. Schlueter (creator of npm ) took over responsibility for Node.js. He is Also An Employee of Joyent. ↔ After 2012, the development of the Node.js project slowed down. In 2014, a developer named Fedor Indutny created io.js, which was a fork of the Node.js project. This led to two separate projects: Node.js, maintained by Joyent, and io.js, developed by Fedor Indutny and the io.js community. ↔ In sep of 2015 , Fedor And Joyent Company was merged and created “node js Foundation” to maintain Node js for future Development. ↔ In 2019 , the Two major Foundation names Js Foundation  and Node js foundation were merged . and created  “open js Foundation” . Now this Open Js Foundation is active for node js Development . #javascript #nodejs #node #programming #backend #developer #fullstackdeveloper #backenddeveloper #fullstack

🚀 **Just Completed Episode 3 and Episode 4 of NamasteNodeJS by Akshay Saini 🚀** 🚀  Here’s a quick overview of what I learned: ### **Node REPL** NodeJS offers a REPL (Read-Evaluate-Print Loop) environment, which is a quick way to write and test NodeJS code.   - To enter REPL mode, just type `node` in your terminal and hit enter.   - REPL is similar to the browser console but runs in the NodeJS runtime environment, which is built on Google’s V8 engine. ### **Global Object in NodeJS** (Very Important) In NodeJS, the global object is referred to as `global`, whereas in the browser, it’s `window`.   - The `global` object in NodeJS provides access to many built-in APIs and functions like `setTimeout` and `setInterval`. - ECMA introduced a standardized global keyword called `globalThis`, which unifies the global object across different environments. This was introduced around 2020 and is now supported in all modern browsers. ### **Working with Modules in NodeJS** In real-world projects, it's not practical to place all your code in a single file. NodeJS allows us to split code into multiple files, referred to as **modules**. This modular approach helps maintain and organize code efficiently. - **How to Use Modules**:     You can include other modules in your code using the `require` keyword. For example: `require("./module1.js")`.   When you use `require`, NodeJS first executes the code in `module1.js` before moving on to the code in the entry file (e.g., `app.js`). ### **Module Protection and Exporting** Modules in NodeJS are protected by default, meaning their variables and functions aren’t accessible just by requiring them. To share functions or variables between modules, you need to explicitly export them. - **Exporting and Importing**:     Typically, you might see something like `module.exports = methodName`, but you can also write `module.exports.methodName = methodName`. Both methods work fine. - **CommonJS vs. ES Modules**:     NodeJS primarily uses **CommonJS modules (CJS)** by default, which are synchronous and run in non-strict mode.     If you set `"type": "module"` in your `package.json`, you switch to **ES Modules (ESM)**, which are asynchronous, run in strict mode, and are the newer standard in JavaScript. This is particularly common in frameworks like React and Angular. ### **Utility Modules in NodeJS** NodeJS also includes **Utility modules**, which are built-in modules that provide essential functionalities. For example, you can `require("node:util")` to use utilities provided by NodeJS. Understanding how to work with modules is crucial for writing scalable and maintainable NodeJS applications. A big shoutout to the NamasteDev.com team for creating such an amazing course and providing this valuable knowledge. Loving every bit of this journey! 🙌 #NodeJS #JavaScript #WebDevelopment #LearningJourney #NamasteDev #Modules #NamasteNodeJS #AkshaySaini #LearnNodeJS   #NamasteJS #NamasteFSD #NodeJSLearning #JSLearning
