Mini React.js Tips #1 | Resources ✨

I thought why not share my React.js (JavaScript library) notes I made when I was studying! I will start from the very beginning with the basics and random notes I made along the way~!

Up first is what you'll need to know to start any basic simple React (+ Vite) project~! 💻

What you'll need:

node.js installed >> click

coding editor - I love Visual Studio Code >> click

basic knowledge of how to use the Terminal

What does the default React project look like?

Step-by-Step Guide

[ 1 ] Create a New Folder: The new folder on your computer e.g. in Desktop, Documents, wherever that will serve as the home for your entire React project.

[ 2 ] Open in your coding editor (will be using VSCode here): Launch Visual Studio Code and navigate to the newly created folder. I normally 'right-click > show more options > Open with Code' on the folder in the File Explorer (Windows).

[ 3 ] Access the Terminal: Open the integrated terminal in your coding editor. On VSCode, it's at the very top, and click 'New Terminal' and it should pop up at the bottom of the editor.

[ 4 ] Create the actual React project: Type the following command to initialize a new React project using Vite, a powerful build tool:

npm create vite@latest

[ 5 ] Name Your Project: Provide a name for your project when prompted.

[ 6 ] Select 'React' as the Framework: Navigate through the options using the arrow keys on your keyboard and choose 'React'.

[ 7 ] Choose JavaScript Variant: Opt for the 'JavaScript' variant when prompted. This is the programming language you'll be using for your React application.

[ 8 ] Navigate to Project Folder: Move into the newly created project folder using the following command:

cd [your project name]

[ 9 ] Install Dependencies: Execute the command below to install the necessary dependencies for your React project (it might take a while):

npm install

[ 10 ] Run the Development Server: Start your development server with the command (the 'Local' link):

npm run dev

[ 11 ] Preview Your Project: Open the link provided in your terminal in your web browser. You're now ready to witness your React project in action!

Congratulations! You've successfully created your first React default project! You can look around the project structure like the folders and files already created for you!

my summer vacation have been so busy…

some of the things i have been up to: i started a ux/ui bootcamp, moved to my first apartment, started driving lessons and i’m currently focusing on front-end development.

a gentle reminder:

it’s only delusional until it’s done.

Any MCR fans in software engineering/web dev?

I'm looking for mutuals who love to code and also love MCR. I wanna do a little project >:D also just want some buds to relate to.

Posting for future reference for when I'm rich and can finally get a tech job in my country and retire to a lonely beach and have massive parties by myself and cook hearty meals and sleep naked on the roof-porch under the night sky by the ocean. And it only took me 3 days to build this fucking crap

[code-es]

let today = new Date("12 December 2023");

Hey coders!

The past couple of months I've been a frontend developer intern at an e-sports company and it's been so amazing! I am realizing that yeah, this is exactly what I want to do! I feel super lucky.

Anyway, today, and for the past like week, I have been struggling with implementing the multiselect from react-select in a form we are building in my team. It's a very complicated field, where you can choose from different lists, with values that need to be replaced and disabled depending on which list you are choosing from and what has already been chosen, so just getting the logic right was tough.

Today I got it working, only to realize I can't style it without all the functionality breaking. Feeling like I've tried everything, I was like: you know what? Fuck it, I'm just gonna make my own. Sooo here I am!

This is the inspo (from react-select):

And this is how far I've gotten(using our on-brand styles):

Anddd here's my (non funcitoning) code:

To break it down:

I have a div that contains a span (which will be rendered from an array of options, to be the yellow chip) and an invisible input field

The div is styled to look like an input field, but in reality it's just a div with spans and an invisible input field following the span (lol special thanks to this stack overflow thread)

When the user types, I am listening to what keys they are pressing with a function I am currently calling handleReturn

If the pressed key is "Enter", I will push the current value of the field to the options array

But! This does not do anything at the moment, since the options array does not tell the component to update itself in any way to display the newly added value! For that, I need to make the options array be a state using the useState() hook from React!

When a state is changed, react's useState can tell, and it will rerender (=update) the component, and then my new value will (...should) be shown as well, since it will be using the new array with new values!

Stay tuned for updates(:

Simple react/next js todo list

Modeled after this tutorial by Web Dev Simplified, but using Next.js and Tailwind

I think following a plain react tutorial while using next js is what gave me some issues, especially being my first react project. I probably should have learned some basic react first before going into frameworks, but oh well.

Trying to line up the text with the CSS paper was a huge pain. I still don't like how it looks but at least it's not floating through the lines anymore lol.

The data persistence gave me the most trouble (took me like FIVE hours 😭). The way it was done in the video did not work for me at all, so I had to figure it out. Local storage can't be accessed during server-side rendering, so accessing localStorage has to be done during client-side rendering, using the useEffect hook. But, as I've learned, the useEffect hook doesn't have a return value, and hooks can only be called at the top level. Then I found out that React intentionally calls useEffect twice and that was resetting my local storage with the empty initialization value -_- But in the end i got it working :)

Now I wanna add some more features; a delete all, clear selected, maybe edit note.

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;

Mini React.js Tips #3 | Resources ✨

Continuing the #mini react tips series, its components making time~!

In React, a component is like a Lego brick for building websites or apps. It's a small, independent part of the user interface (UI) that you can reuse whenever you need it. These components can be combined to create bigger and more complex applications. Examples are the header, footer, cards, asides, etc!

What you'll need:

know how to create a React project >> click

know the default React project's file structure >> click

know basic HTML

know basic JavaScript

basic knowledge of using the Terminal

What We Are Creating:

The footer at the bottom!

[ 1 ] Navigate to the 'src' Folder: Open your project in Visual Studio Code, locate the 'src' folder, and right-click on it.

[ 2 ] Create a New File: Click 'New File' to create the file within the 'src' folder. This file will house the code for your React component.

[ 3 ] Naming Conventions: Give your component a name, according to the convention of starting with a capital letter. This naming convention is essential for React to recognize your component~!!

[ 4 ] Create The Initial Function: Open the file and type:

export default function [name of component]() {}

[ 5 ] Insert The return() Statement: The statement is used within a component to specify what content should be rendered when the component is invoked or used. Type:

return()

*the error is there because we haven't added anything inside yet, don't worry!

[ 6 ] Insert The Empty Tags: Inside of the return(), add empty tags (tags that don't have a specified element inside of them).

[ 7 ] Time For Some HTML: Inside the empty tags, enter the normal HTML elements that you want~!

[ 8 ] Integration with App.jsx: Navigate to the 'App.jsx' file in the project, which is typically the entry point of your React application. At the top, import your newly created component. Type:

import [name of component] from './[location of the component]'

[ 9 ] Use Your Component: Inside the return() statement of the 'App()' function, include your component using the following syntax:

<[name of your component] />

[ 10 ] Run the Development Server: Start your development server with the command (the 'Local' link):

npm run dev

[ 11 ] Preview Your Project: Open the link provided in your terminal in your web browser. Witness your component in action!

Congratulations! You made your first component! Try and create some new ones and place them around in the App()~!

Framework-heavy JS websites mistake substance for flashy lights. Meanwhile, static HTML just says what it wants to tell.

"web app" websites with a billion lines of react code and a 100 MB cache and enough tracking elements to find out what i had for breakfast, that take 20 seconds to load on my gaming laptop... they are like little inbred bulldogs to me. What are you puppy mill ass web devs doing!! your awful JS isn't making them "aesthetic," youre giving them serious breathing problems >:(
