Vite is a modern build tool that offers faster development times and optimized builds. It aligns with modern web standards and provides out-of-the-box support for TypeScript, making it an excellent choice for React development. In this blog post, we will learn how to get started with React by creating a new app using Vite. We will follow the steps to set up our development environment and build our first React application.

Quick Start​

To get started with Vite, we need to have Node.js installed on our system. We can install Node.js by downloading the installer from the official website or using a package manager. Once we have Node.js installed, we can use npm to create a new Vite project with the React template.

To quickly get started with Vite and React, follow these steps:

npm create vite@latest my-app --template react

This command will create a new Vite project called my-app using the React template. It will set up the project structure and install the necessary dependencies. We can then navigate to the my-app directory and start the development server to see our new React application in action.

Now navigate to the my-app directory:

cd my-app

if you prefer using npm:

npm install

Or, if you prefer using yarn:

yarn

Now start the development server:

npm start

Or, if you prefer using yarn:

yarn start

Once the development server has started, open http://localhost:3000/ in your browser to see your new React application. You can start building your React components, defining routes, and managing state using the React Context API.

Project Structure​

The Vite project structure for a new React application is minimal and easy to understand. It provides a clean and organized layout that aligns with modern web development practices. Here is an overview of the project structure:

my-app
├── node_modules
├── public
│   ├── favicon.ico
│   ├── index.html
├── src
│   ├── App.css
│   ├── App.jsx
│   ├── index.css
│   ├── index.jsx
├── .gitignore
├── package.json
├── README.md

The public directory contains the static assets for our application, such as the index.html file and the favicon.ico icon. The src directory contains the source code for our React application, including the main index.jsx file and the App.jsx component.

Building Our First React Application​

Now that we have our development environment set up and our project structure in place, we can start building our first React application. We can create new components, define routes, and manage state using the React Context API. We can also use popular libraries such as React Router and React hooks to enhance our application.

To learn more about building React applications with Vite, refer to the official React documentation. The documentation provides detailed information on React concepts, best practices, and advanced topics.

Git is a powerful tool for managing the development of software projects, but it can be challenging to use effectively. In this article, we'll take a look at some best practices for using Git, including how to structure your commits, how to manage branches, and how to collaborate with others. By following these best practices, you can make your development process more efficient and less error-prone.

Commit Often, Perfect Later, Publish Once​

One of the most important best practices for using Git is to commit your changes often. This means that you should make small, focused commits that capture a single logical change to your code. By committing often, you can keep a detailed history of your changes, which makes it easier to understand the evolution of your codebase and to track down bugs.

When you're working on a new feature or fixing a bug, it's important to commit your changes frequently, even if they're not perfect. You can always go back and revise your commits later to clean them up and make them more coherent. By committing often and revising later, you can avoid the temptation to make large, sweeping changes to your code all at once, which can lead to confusion and errors.

Once you're satisfied with your changes, you can publish them to a shared repository, such as GitHub or Bitbucket. By publishing your changes once, you can make it easier for others to review your work and to collaborate with you. This can help to prevent merge conflicts and to ensure that everyone is working from the most up-to-date version of the codebase.

Structure Your Commits​

When you're committing your changes, it's important to structure your commits in a way that makes it easy to understand the evolution of your codebase. This means that you should avoid making large, monolithic commits that capture multiple unrelated changes. Instead, you should make small, focused commits that capture a single logical change to your code.

One way to structure your commits is to use the "atomic commit" pattern, which involves making a series of small, focused commits that capture a single logical change to your code. For example, if you're working on a new feature, you might make a series of commits that add individual components of the feature, such as the user interface, the business logic, and the data model. By structuring your commits in this way, you can make it easier to understand the evolution of your codebase and to track down bugs.

Another way to structure your commits is to use the "semantic commit" pattern, which involves using a standardized format for your commit messages. For example, you might use a format like "feat: add new feature" or "fix: correct bug in user interface". By using a standardized format for your commit messages, you can make it easier to understand the purpose of each commit and to navigate through the history of your codebase.

Manage Your Branches​

When you're working on a software project, it's important to manage your branches effectively. This means that you should create a new branch for each new feature or bug fix that you're working on, and that you should merge your branches back into the main codebase once you're finished with them.

By managing your branches effectively, you can make it easier to collaborate with others and to keep your codebase organized. For example, if you're working on a new feature, you might create a new branch for the feature, make your changes on the branch, and then merge the branch back into the main codebase once the feature is complete. By doing this, you can make it easier for others to review your work and to collaborate with you, and you can avoid introducing bugs and conflicts into the main codebase.

Collaborate with Others​

One of the most powerful features of Git is its ability to help you collaborate with others. By using Git, you can make it easier to share your work with others, to review their work, and to resolve conflicts and merge changes together.

When you're collaborating with others, it's important to communicate effectively and to follow best practices for using Git. For example, you should make sure to pull the latest changes from the shared repository before you start working on a new feature or bug fix, and you should make sure to push your changes to the shared repository once you're finished with them. By following these best practices, you can make it easier to collaborate with others and to keep your codebase organized and up-to-date.

Conclusion​

Git is a powerful tool for managing the development of software projects, but it can be challenging to use effectively. By following best practices for using Git, such as committing often, structuring your commits, managing your branches, and collaborating with others, you can make your development process more efficient and less error-prone. By doing this, you can make it easier to understand the evolution of your codebase, to track down bugs, and to collaborate with others. Happy coding!

I have been using web clipper to save articles and blog posts for a while now. It's a great tool to save content from the web and organize it in a clean and readable format. However, the markdown files generated by web clipper are not always consistent, and I often find myself manually editing them to make them more readable.

One of the common issues I encounter is inconsistent formatting of the front matter in the markdown files. The front matter is a block of metadata at the beginning of a markdown file that contains information such as the title, author, tags, date, and description of the content. Here's an example of what the front matter looks like:

---
title: 'Sed: Normalize markdown file with Regex'
author: Ajay Dhangar
tags: [sed, regex, web clipper]
date: 2020-11-26 21:13:28
description: How to normalize markdown file with Regex
draft: false
---

As you can see, the front matter is enclosed in three dashes (---) at the beginning and end of the block, and each key-value pair is separated by a colon (:). The keys and values are also enclosed in single quotes (') to ensure that special characters are escaped properly.

To make the front matter consistent across all my markdown files, I decided to use the sed command-line utility to write a simple regular expression that would normalize the front matter. Here's the regular expression I came up with:

sed -i -E "s/^---\n(.*: .*\n)+---\n//g" file.md

Let's break down the regular expression:

• ^---\n matches the opening three dashes at the beginning of the file, followed by a newline character.
• (.*: .*\n)+ matches one or more lines containing a key-value pair, where the key is followed by a colon and a space, and the value is followed by a newline character.
• ---\n matches the closing three dashes at the end of the block, followed by a newline character.
• /g is a flag that tells sed to perform the substitution globally, i.e., on all matching lines in the file.

When I run this command on a markdown file, it removes the existing front matter and leaves me with just the content of the file. This is exactly what I want, as I can then manually add a consistent front matter to the file.

I hope this example gives you an idea of how powerful regular expressions can be when used with command-line utilities like sed. With a little bit of practice, you can write regular expressions to perform complex text manipulations with ease. If you're interested in learning more about regular expressions, I highly recommend checking out the RegexOne interactive tutorial, which is a great resource for beginners.

In the early days of web development, the most common way to deploy a website was to use an FTP client. This involved manually uploading files to a remote server, which was a time-consuming and error-prone process. As web development practices evolved, so did the tools and techniques for deploying websites. One of the most significant advancements in this area has been the introduction of continuous integration (CI) and continuous deployment (CD) pipelines, which automate the process of building and deploying web applications.

In this article, we'll take a look at the evolution of remote file management, from the use of FTP clients to the adoption of GitHub Actions for automated deployment.

The FTP client era​

In the early days of web development, the most common way to deploy a website was to use an FTP client. This involved manually uploading files to a remote server, which was a time-consuming and error-prone process. Developers would typically make changes to their local files, then use an FTP client to upload those changes to the server. This process was often slow and cumbersome, and it was easy to make mistakes that could result in broken websites.

The rise of CI/CD pipelines​

As web development practices evolved, so did the tools and techniques for deploying websites. One of the most significant advancements in this area has been the introduction of continuous integration (CI) and continuous deployment (CD) pipelines. CI/CD pipelines automate the process of building and deploying web applications, making it faster, more reliable, and less error-prone than manual deployment methods.

GitHub Actions for automated deployment​

One of the most popular CI/CD solutions for web development is GitHub Actions. GitHub Actions is a powerful, flexible, and easy-to-use tool for automating the build, test, and deployment processes of web applications. With GitHub Actions, you can define custom workflows that automatically build and deploy your web applications whenever you push changes to your repository. This makes it easy to ensure that your websites are always up-to-date and error-free, without the need for manual intervention.

Conclusion​

The evolution of remote file management has come a long way since the days of using FTP clients to manually upload files to remote servers. With the introduction of CI/CD pipelines and tools like GitHub Actions, web developers now have powerful, automated solutions for building and deploying web applications. These tools make it faster, easier, and more reliable to deploy websites, and they help ensure that your websites are always up-to-date and error-free. If you're still using an FTP client to deploy your websites, it's time to consider upgrading to a more modern, automated solution like GitHub Actions.

Debugging tests in a React application can be challenging, but fear not! We've got you covered with this step-by-step guide to help you overcome the common hurdles and make your tests shine. Let's dive in:

Step 1: Install Create React App

If you haven't already set up your Create React App project, start by installing it:

npx create-react-app my-app
cd my-app

Step 2: Writing a Test

Create a simple React component (e.g., a Button) in a separate file and write a test for it. For example:

import React from 'react';

const Button = () => {
  return <button>Click Me</button>;
};

export default Button;

import React from 'react';
import { render, screen } from '@testing-library/react';
import Button from './Button';

test('renders the button', () => {
  render(<Button />);
  const buttonElement = screen.getByText('Click Me');
  expect(buttonElement).toBeInTheDocument();
});

Step 3: Run the Tests

Execute the tests using the following command:

npm test

Step 4: Spotting the Failure

If the test fails, don't panic! First, identify the failing test case.

Step 5: Reproduce the Failure Locally

Make sure the failure occurs consistently by reproducing it locally. Ensure that you're running the correct test files and dependencies.

Step 6: Debugging Techniques

Now, let's employ some debugging techniques to resolve the issue:

6.1. Use console.log

Place console.log statements at different points in your test to check the values of variables or components. For example:

test('renders the button', () => {
  render(<Button />);
  console.log(screen.getByRole('button').outerHTML);
  const buttonElement = screen.getByText('Click Me');
  console.log(buttonElement); // Check the button element in the console
  expect(buttonElement).toBeInTheDocument();
});

6.2. Utilize debugger

You can use the debugger keyword to pause test execution at a specific point. Open your browser's developer tools to inspect variables and the call stack. For example:

test('renders the button', () => {
  render(<Button />);
  debugger; // Execution will pause here, and you can inspect the app and test code.
  const buttonElement = screen.getByText('Click Me');
  expect(buttonElement).toBeInTheDocument();
});

6.3. Inspect with Chrome DevTools

Open your app in Chrome, right-click, and select "Inspect." Navigate to the "Console" tab to interactively debug your tests using the same tools you use for your regular app.

6.4. Snapshot Testing

If you suspect issues with rendering, consider using snapshot testing. Jest can generate snapshots of your components and compare them for changes. Learn more about snapshot testing in the official documentation.

Step 7: Fix the Test

Based on your observations during debugging, fix the failing test case. It might involve modifying the component or adjusting your expectations in the test.

Step 8: Rerun the Tests

After making changes, run the tests again to ensure everything is working correctly:

npm test

Step 9: Celebrate Success!

Congratulations! You've successfully debugged your test and conquered the Bug Monsters. Repeat these steps whenever you encounter testing issues in your React applications.
