Mini React.js Tips #2 | Resources ✨

Continuing the #mini react tips series, it's time to understand what is going on with the folders and files in the default React project - they can be a bit confusing as to what folder/file does what~!

What you'll need:

know how to create a React project >> click

already taken a look around the files and folders themselves

What does the file structure look like?

✤ node_modules folder: contains all the dependencies and packages (tools, resources, code, or software libraries created by others) needed for your project to run properly! These dependencies are usually managed by a package manager, such as npm (Node Package Manager)!

✤ public folder: Holds static assets (files that don't change dynamically and remain fixed) that don't require any special processing before using them! These assets are things like images, icons, or files that can be used directly without going through any additional steps.

✤ src folder: This is where your main source code resides. 'src' is short for source.

✤ assets folder: This folder stores static assets such as images, logos, and similar files. This folder is handy for organizing and accessing these non-changing elements in your project.

✤ App.css: This file contains styles specific to the App component (we will learn what 'components' are in React in the next tips post~!).

✤ App.jsx: This is the main component of your React application. It's where you define the structure and behavior of your app. The .jsx extension means the file uses a mixture of both HTML and JavaScript - open the file and see for yourself~!

✤ index.css: This file contains global styles that apply to the entire project. Any styles defined in this file will be applied universally across different parts of your project, providing a consistent look and feel.

✤ main.jsx: This is the entry point of your application! In this file, the React app is rendered, meaning it's the starting point where the React components are translated into the actual HTML elements displayed in the browser. Would recommend not to delete as a beginner!!

✤ .eslintrc.cjs: This file is the ESLint configuration. ESLint (one of the dependencies installed) is a tool that helps maintain coding standards and identifies common errors in your code. This configuration file contains rules and settings that define how ESLint should analyze and check your code.

✤ .gitignore: This file specifies which files and folders should be ignored by Git when version-controlling your project. It helps to avoid committing unnecessary files. The node_modules folder is typically ignored.

✤ index.html: This is the main HTML file that serves as the entry point for your React application. It includes the necessary scripts and links to load your app.

✤ package.json: A metadata file for your project. It includes essential information about the project, such as its name, version, description, and configuration details. Also, it holds a list of dependencies needed for the project to run - when someone else has the project on their local machine and wants to set it up, they can use the information in the file to install all the listed dependencies via npm install.

✤ package-lock.json: This file's purpose is to lock down and record the exact versions of each installed dependency/package in your project. This ensures consistency across different environments when other developers or systems install the dependencies.

✤ README.md: This file typically contains information about your project, including how to set it up, use it, and any other relevant details.

✤ vite.config.js: This file contains the configuration settings for Vite, the build tool used for this React project. It may include options for development and production builds, plugins, and other build-related configurations.

Congratulations! You know what the default folders and files do! Have a play around and familiarise yourself with them~!

i want to keep tumblr because i like aesthetics

aesthetic aggregation is important because it allows for intimate relationships to develop outside of life-long domesticated-servile contracts

you transfer

love energy,

actually, when you share your aesthetic, and merge, like that

however

i don't think its possible to make organic relationships the same way it was a decade ago, no, entirely too sanitized

i highly doubt, since the algorithm that i'll ever oganically run into; actually its absurd to even finish that sentence

luckily, i became a sysadmin / programmer, in the interem period, and can actually build the tools this time around

i have an idea for an aesthetic aggregator portal place that combines dump.fm & tumblr with cellular automata, like a living pool you gaze into and everything's a ripple on a wave, man, that's like connected, woah

and i'm schemeing on it, i love lisp, when i go looking everything i want to do is available to me like channeling a spell... somebody already wrote scheme to wasm, that really shouldn't be too hard... still looking for alternate ways to chat :D hmu on xmpp it's exactly like AIM

i've tried node/npm, python, package managers... the best most satisfying one if you're going to go and install a big library, blob thing like that, is probably some flavor of emacs... for me, this is a personal preference, the fact that you 'can' do anything that rust/python/go/js can do in LISP... is enough for me, because, it is elegant, it is more pleasant to look at and easier to read, idk. loving my time with it recently and have been knocking it out of the park most days recently... the past 7 years i've been working on a top secret project, which will have a working alpha demo of the basic features by the end of next week :D

the best os rn is a freeBSD jail with guixSD GNU/linux-libre there's also hyperbola/BSD in the works you want to try to phase out the linux kernel because of all the google/microsoft shenanigans creeping in, you don't need unix/linux any more you can do all your daily driver stuff on an embedded, low power risc soc that costs under a hundo you need less overhead for embedded systems, there's microkernels like genome, and platforms like zephyr, its ok to move away idk one thing i learned its good to take a step back and look at the scope of what you're trying to achieve, try to strip away all the unneccessary parts... a mhz is 1,000,000 calculations a microsecond or whatever, when you sit down and write a piece of code how many calculations exactly do you need to do to do your business, honestly.

^these are the 3 am ramblings of a minimalist

i'm trying to find peers here on my site that's connected to the internet that's why i'm sending messages to it about my interests, pardon me, sir please send $1 to this address

React JS

Component-Based Architecture:

React applications are built using components, which are reusable, self-contained pieces of the UI. Components can be nested, managed, and handled independently, leading to better maintainability and scalability.

JSX (JavaScript XML):

React uses JSX, a syntax extension that allows HTML to be written within JavaScript. This makes the code more readable and easier to write.

Virtual DOM:

React maintains a virtual DOM, an in-memory representation of the actual DOM. When the state of an object changes, React updates the virtual DOM and efficiently determines the minimal set of changes needed to update the real DOM, leading to performance improvements.

One-Way Data Binding:

Data flows in one direction, from parent to child components, which makes the data flow and logic easier to understand and debug.

State Management:

React components can maintain internal state, making it easy to build dynamic and interactive UIs. For more complex state management, libraries like Redux or Context API can be used.

Advantages of Using React

Performance:

Due to the virtual DOM, React minimizes direct manipulation of the DOM, resulting in better performance for dynamic applications.

Reusable Components:

Components can be reused across different parts of an application, reducing the amount of code and enhancing consistency.

Strong Community and Ecosystem:

A large community and a rich ecosystem of tools and libraries support React, making it easier to find solutions, get support, and integrate with other technologies.

SEO Friendly:

React can be rendered on the server using Node.js, making web pages more SEO-friendly compared to traditional client-side rendering.

Getting Started with React

To start building applications with React, you need to have Node.js and npm (Node Package Manager) installed. Here’s a basic setup to create a new React application:

Install Node.js and npm:

Download and install from Node.js website.

Create a New React Application:

You can use Create React App, an officially supported way to create single-page React applications with no configuration required:

npx create-react-app my-app cd my-app npm start

import React from 'react';

function Welcome(props) { return

Hello, {props.name}

; }

export default Welcome;

The Debate of the Decade: What to choose as the backend framework Node.Js or Ruby on Rails?

New, cutting-edge web development frameworks and tools have been made available in recent years.  While this variety is great for developers and company owners alike, it does come with certain drawbacks.  This not only creates a lot of confusion but also slows down development at a time when quick and effective answers are essential.  This is why discussions about whether Ruby on Rails or Noe.js is superior continue to rage.  What framework is best for what kind of project is a hotly contested question.  Nivida Web Solutions is a top-tier web development company in Vadodara.  Nivida Web Solutions is the place to go if you want to make a beautiful website that gets people talking.

Identifying the optimal option for your work is challenging.  This piece breaks things down for you.  Two widely used web development frameworks, RoR and Node.js, are compared and contrasted in this article.  We'll also get deep into contrasting RoR and Node.js.  Let's get started with a quick overview of Ruby on Rails and Node.js. 

NodeJS: 

This method makes it possible to convert client-side software to server-side ones.  At the node, JavaScript is usually converted into machine code that the hardware can process with a single click.  Node.js is a very efficient server-side web framework built on the Chrome V8 Engine.  It makes a sizable contribution to the maximum conversion rate achievable under normal operating conditions. 

There are several open-source libraries available through the Node Package Manager that make the Node.js ecosystem special.  Node.js's built-in modules make it suitable for managing everything from computer resources to security information.  Are you prepared to make your mark in the online world? If you want to improve your online reputation, team up with Nivida Web Solutions, the best web development company in Gujarat. 

Key Features:

·         Cross-Platforms Interoperability

·         V8 Engine

·         Microservice Development and Swift Deployment

·         Easy to Scale

·         Dependable Technology 

Ruby on Rails: 

The back-end framework Ruby on Rails (RoR) is commonly used for both web and desktop applications.  Developers appreciate the Ruby framework because it provides a solid foundation upon which other website elements may be built.  A custom-made website can greatly enhance your visibility on the web.  If you're looking for a trustworthy web development company in India, go no further than Nivida Web Solutions.

Ruby on Rails' cutting-edge features, such as automatic table generation, database migrations, and view scaffolding, are a big reason for the framework's widespread adoption. 

Key Features:

·         MVC Structure

·         Current Record

·         Convention Over Configuration (CoC)

·         Automatic Deployment

·         The Boom of Mobile Apps

·         Sharing Data in Databases 

Node.js v/s RoR: 

·         Libraries:

The Rails package library is called the Ruby Gems.  However, the Node.Js Node Package Manager (NPM) provides libraries and packages to help programmers avoid duplicating their work. Ruby Gems and NPM work together to make it easy to generate NPM packages with strict version control and straightforward installation. 

·         Performance:

Node.js' performance has been lauded for its speed. Node.js is the go-to framework for resource-intensive projects because of its ability to run asynchronous code and the fact that it is powered by Google's V8 engine.  Ruby on Rails is 20 times less efficient than Node.js. 

·         Scalability:

Ruby's scalability is constrained by comparison to Node.js due to the latter's cluster module.  In an abstraction-based cluster, the number of CPUs a process uses is based on the demands of the application. 

·         Architecture:

The Node.js ecosystem has a wealth of useful components, but JavaScript was never designed to handle backend activities and has significant constraints when it comes to cutting-edge construction strategies.  Ruby on Rails, in contrast to Node.js, is a framework that aims to streamline the process of building out a website's infrastructure by eliminating frequent installation problems. 

·         The learning curve:

Ruby has a low barrier to entry since it is an easy language to learn.  The learning curve with Node.js is considerably lower.  JavaScript veterans will have the easiest time learning the language, but developers acquainted with various languages should have no trouble. 

Final Thoughts: 

Both Node.JS and RoR have been tried and tested in real-world scenarios.  Ruby on Rails is great for fast-paced development teams, whereas Node.js excels at building real-time web apps and single-page applications. 

If you are in need of a back-end developer, Nivida Web Solutions, a unique web development agency in Gujarat, can assist you in creating a product that will both meet and exceed the needs of your target audience.

By mastering both Angular 18 and ASP NET 8.0, you'll be well-equipped to create full-stack web applications that are not only fast and responsive but also secure and scalable.

Getting Started with Angular 18

To Accelerate Your Learning: Master Angular 18 and ASP NET 8.0, let's start with Angular 18. Here’s a step-by-step guide to help you get up and running:

1. Setting Up Your Development Environment

Before you begin, ensure your development environment is ready:

Node.js and npm: Angular requires Node.js and npm (Node Package Manager) to be installed. Download and install the latest version from the official website.

Angular CLI: The Angular Command Line Interface (CLI) is a powerful tool for creating, managing, and deploying Angular applications. Install it using the command: bash Copy code npm install -g @angular/cli

Code Editor: Use a code editor like Visual Studio Code or WebStorm for writing your Angular code.

2. Creating Your First Angular Application

With your environment set up, it’s time to create your first Angular application:

bash

Copy code

ng new my-angular-app

This command will generate a new Angular project with a basic structure. You can then navigate to the project directory and start the development server:

bash

Copy code

cd my-angular-app

ng serve

3. Understanding Angular Components

Components are the building blocks of any Angular application. Each component consists of:

HTML Template: Defines the view.

TypeScript Class: Contains the logic.

CSS/SCSS: Handles the styling.

Creating a new component is simple:

bash

Copy code

ng generate component my-component

4. Data Binding and Directives

Angular offers powerful data-binding features that allow you to synchronize data between the model and view. There are four types of data binding:

Interpolation: Binding data from the TypeScript class to the HTML template.

Property Binding: Binding a property of an element to a TypeScript class property.

Event Binding: Binding an event (like a button click) to a method in the TypeScript class.

Two-Way Binding: Synchronizing data between the view and model.

Directives are special instructions in the DOM. They can change the appearance or behavior of a DOM element. Examples include *ngIf, *ngFor, and ngClass.

5. Services and Dependency Injection

In Angular, services are used to share data and logic across components. Dependency Injection (DI) is a design pattern used to provide dependencies to a class from external sources rather than creating them internally. This promotes modularity and reusability in your code.

6. Routing and Navigation

Routing is essential for creating single-page applications. Angular’s router enables you to define routes and navigate between them:

typescript

Copy code

const routes: Routes = [

  { path: '', component: HomeComponent },

  { path: 'about', component: AboutComponent }

];

Use the routerLink directive in your templates to navigate between routes:

html

Copy code

<a routerLink="/about">About</a>

Mastering ASP NET 8.0

Now that you have a solid foundation in Angular 18, it’s time to focus on ASP NET 8.0. This back-end framework will allow you to create robust APIs and services that your Angular applications can interact with.

1. Setting Up ASP NET 8.0

Before you start building with ASP NET 8.0, ensure you have the following tools installed:

.NET SDK: Download and install the latest .NET SDK from the official website.

Visual Studio: Use Visual Studio 2024 or Visual Studio Code as your IDE.

2. Creating Your First ASP NET 8.0 Application

You can create a new ASP NET 8.0 application using the .NET CLI:

bash

Copy code

dotnet new webapi -n MyAspNetApp

This command creates a new Web API project. You can then navigate to the project directory and run the application:

bash

Copy code

cd MyAspNetApp

dotnet run

3. Understanding ASP NET 8.0 Architecture

ASP NET 8.0 follows a Model-View-Controller (MVC) architecture, where:

Model: Represents the application data.

View: Handles the user interface.

Controller: Manages the interaction between the Model and View.

4. Building RESTful APIs

ASP NET 8.0 is ideal for building RESTful APIs that can be consumed by your Angular application. Here’s how you can create a simple API:

Create a Model: Define the data structure.

Create a Controller: Handle HTTP requests (GET, POST, PUT, DELETE) and return responses.

Use Entity Framework: For database operations like CRUD (Create, Read, Update, Delete).

5. Securing Your Application

Security is a major concern in web development. ASP NET 8.0 provides various tools to secure your application:

Authentication and Authorization: Implement user authentication using Identity or OAuth.

Data Protection: Protect sensitive data using encryption and secure data storage.

One of the most powerful combinations in web development is integrating a front-end framework like Angular with a back-end framework like ASP.NET. Here’s how you can achieve that:

1. Setting Up a RESTful Service

First, create a RESTful service in ASP NET 8.0 that your Angular application can consume. This service will handle data operations like fetching, updating, and deleting records.

2. Consuming the Service in Angular

In your Angular application, use the HttpClientModule to consume the RESTful service. Here's an example of how to fetch data from an API:

typescript

Copy code

import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) {}

getData() {

  this.http.get('https://api.example.com/data')

    .subscribe(response => {

      console.log(response);

    });

}

3. Real-Time Communication with SignalR

For real-time features like notifications or chat, integrate SignalR with your Angular application. SignalR is a library for ASP.NET that allows bi-directional communication between the server and client.
