We can place the author or title name over the image using the GridListTileBar Component in ReactJS. This component adds an overlay over the child component. Material UI for React has this component available for us and it is very easy to integrate. We can use the GridListTileBar component in ReactJS using the following approach.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command:

cd foldername

Step 3: After creating the ReactJS application, Install the material-ui modules using the following command:

npm install @material-ui/core npm install @material-ui/icons

Project Structure: It will look like the following.

Filename-App.js: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

import React from 'react';
import GridList from '@material-ui/core/GridList';
import GridListTile from '@material-ui/core/GridListTile';
import GridListTileBar from '@material-ui/core/GridListTileBar';
import ListSubheader from '@material-ui/core/ListSubheader';
import IconButton from '@material-ui/core/IconButton';
import InfoIcon from '@material-ui/icons/Info';

const App = () => {
return (
    <div style={{ width: 700, margin: 'auto' }}>
    <h3>How to put title over image in ReactJS?</h3>
    <GridList cellHeight={180} >
        <GridListTile key="Subheader" cols={2} rows={4} style={{ height: 'auto' }}>
        <ListSubheader component="div">December</ListSubheader>
        </GridListTile>
        <GridListTile>
        <img
        src="https://write.geeksforgeeks.org/static/media/Group%20210.08204759.svg"/>

Create a Random Joke using React app through API

Siddhesh Rajale — Thu, 29 Feb 2024 17:51:07 +0000

In this guide, we'll embark on a journey to build an interactive website that dynamically fetches and displays jokes from an external API using the power of React. With React as our primary framework, we'll create a seamless user experience where each page reload and button click unveils a fresh, humor-filled joke without the need to refresh the entire page.

Prerequisite: The pre-requisites for this project are:

React
Function Components
ReactJS AJAX and API
useState Approach: Decoding the Joke-Generating Component In our architecture, the "Joke" file takes center stage as a functional component. Within this component, a crucial state variable, "Joke," is initialized to an empty string. The magic unfolds as the output dynamically adjusts based on the state of this variable. The essence lies in the seamless rendering of the joke content, driven by the underlying state.

Adding to the intricacy, this component smartly incorporates the "Button" component. Here, the "Button" is not just any button; it's a functional component meticulously imported for its role in triggering the joke generation process. Clicking this button sets the gears in motion, unveiling a fresh joke.

Diving deeper, the "Button" component is a compact yet powerful functional component, exclusively designed to render a button element. Adding a layer of sophistication, we pass along some props to this "Button" companion. The prop in question is a method named "callAPI," a linchpin in fetching jokes from the API whenever the code executes the fetching sequence.

Steps to create the application:

Step 1: Initialize the project from terminal using the command.

npx create-react-app jokegenerator
Step 2: Navigate to the project folder using the command.
cd jokegenerator

Step 3: Create a folder called components and add two files in it Button.js and Joke.js
Example: Write the following code in respective files.

App.js: This file imports the components to render it on the web page
Joke.js: This file contains the joke to be displayed and makes the API call
Joke.css: This file contains the styling of all the elements
Button.js: This file contains the button component which generates the joke on click
Button.css: This file contains the styling of button element

Javascript

// App.js

import Joke from "./components/Joke";

function App() {
    return (
        <div className="App">
            <h1>Joke Generator Using React and Joke API</h1>
            <Joke/>
        </div>
    );
}

export default App;


// Joke.js

import React from "react";

import Button from "./Button";
import './Joke.css';

const Joke = () => {
    const [Joke, setJoke] = React.useState("");

    const fetchApi = () => {
        fetch("https://sv443.net/jokeapi/v2/joke/Programming?type=single")
            .then((res) => res.json())
            .then((data) => setJoke(data.joke));
    };

    return (
        <div className="joke">
            <Button callApi={fetchApi} /> 
            <p>{Joke}</p>    
        </div>
    );
}

export default Joke;

CSS


/* Joke.css */

body {
    background-color: rgb(47, 97, 80);
}

.joke {
    width: auto;
    height: auto;
    margin: auto;
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    color: beige;
}

h1 {
    text-align: center;
    color: beige;
}

Javascript


// Button.js

import React from "react";
import './Button.css'

const Button = (props) => {
    return <button onClick={props.callApi}>
        Click to generate a joke.
    </button>;
}

// Export Button Component
export default Button;

CSS

/* Button.css */

button {
    display: inline-block;
    padding: 10px 20px;
    background-color: #70a03a;
    color: #ffffff;
    border: none;
    font-size: 16px;
    cursor: pointer;
    border-radius: 8px;
    transition: background-color .5s;
}

button:hover {
    background-color: #c1f590;
}

button:active {
    background-color: #297910;
}

Steps to run the application:

Step 1: Type the following command in terminal of your project directory

npm start
Step 2: Type the following URL in your web browser.
http://localhost:3000/

Demystifying Docker: Simplifying Application Deployment

Siddhesh Rajale — Thu, 29 Feb 2024 17:41:37 +0000

In the realm of modern software development, Docker has emerged as a game-changer. This open-source platform enables developers to containerize their applications, providing a standardized and executable component known as the Dockerfile. This file encapsulates the OS libraries and dependencies required to run the application, ensuring a consistent environment across different systems.

What is Docker?(Understanding Docker: A Developer's Companion)
Docker, at its core, is a platform that empowers developers to encapsulate their applications within containers. While containers were not a new concept, Docker played a pivotal role in popularizing them. The heart of Docker lies in two key components: the Docker Engine and Docker Hub. The former executes on your local system to run your application, while the latter acts as a cloud service, facilitating the sharing of Docker images globally.

What is Dockerfile?(Blueprint for Containerization)

At the heart of Docker lies the Dockerfile, a file written in a Domain Specific Language (DSL) that contains instructions for crafting a Docker image. Think of it as the source code of your image. This file meticulously outlines the processes necessary to swiftly generate an image. When developing your application, creating a Dockerfile is a best practice, as the Docker daemon meticulously executes instructions from top to bottom.

Dockerfile is the source code of the image

What is Docker Image?(Portable Software Package)

A Docker image is a sophisticated artifact composed of several layers, serving as a lightweight and self-sufficient executable package. It encapsulates all components essential for running a piece of software, encompassing the code, runtime, libraries, environment variables, and configuration files. Essentially, a Docker image ensures consistency and portability, making it an ideal choice for seamless software deployment.
Docker Editions: Choosing the Right Fit
Docker offers two editions - Enterprise Edition (EE) and Community Edition (CE). Tailored for different needs, EE caters to businesses and IT teams handling mission-critical production applications. On the other hand, CE suits smaller teams exploring Docker's capabilities. Understanding your project's scale and requirements will guide you in selecting the most suitable Docker edition.

In essence, Docker revolutionizes how developers design, distribute, launch, run, upgrade, and manage containers. It brings a level of standardization and efficiency to the software development lifecycle, making it a go-to tool for modern application deployment. So, whether you're orchestrating complex enterprise applications or just getting started with containerization, Docker has something to offer for everyone in the vast landscape of software development. Happy coding!

Summarizer Website using MEAN Stack

Siddhesh Rajale — Mon, 26 Feb 2024 18:09:34 +0000

Introduction:

In today's fast-paced world, dealing with information overload is a common challenge. Picture having a tool that swiftly summarizes lengthy articles, allowing you to grasp the main points without spending excessive time reading. In this article, we'll walk you through the process of crafting a Summarizer Website using the MEAN Stack.

Project Preview:
Before we jump into the details, let's take a sneak peek at what our Summarizer Website will look like. This project is designed to offer users a straightforward and intuitive interface. Users can input large amounts of text and, in return, receive concise summaries.

**
Prerequisites:**
Before you start coding, make sure you have the following prerequisites installed on your system:

MongoDB
Express.js
Angular
Node.js

Approach:
Our approach to building the Summarizer Website using the MEAN Stack involves making the most of each component's strengths:

a. MongoDB: Setting up the Database

MongoDB acts as our database to store user data and summarized content. Begin by installing and configuring MongoDB on your system. Create a database for user information and another collection for storing summaries.

b. Express.js and Node.js: Building the Backend

Express.js, a web application framework for Node.js, serves as our backend framework. Node.js manages server-side operations. Develop RESTful APIs using Express to handle data flow between the frontend and the MongoDB database. Set up routes for user input, text processing, and summary retrieval.

**
c. Angular: Developing the Frontend**

Angular is our frontend framework, providing a robust and structured environment for UI development. Design a clean and user-friendly interface where users can input extensive text. Use Angular components to handle different parts of the UI, such as input forms and result displays. Implement services to communicate with backend APIs.

d. Connecting Frontend and Backend: Ensuring Seamless Communication

Establish a seamless connection between the frontend and backend. Use Angular services to make HTTP requests to the Express.js backend. Ensure proper handling of asynchronous operations and error cases. Implement mechanisms for sending user input from the frontend to the backend and receiving summarized content in return.

This approach ensures that each component in the MEAN Stack performs its specific role effectively. MongoDB stores data, Express.js and Node.js handle server-side operations, and Angular provides a dynamic and interactive user interface. As we proceed with the implementation steps, we'll delve deeper into each aspect, guiding you through the intricacies of building this comprehensive web application.

Let's break down the steps to create our Summarizer Website:

**
a. Set up the MongoDB Database:**

Think of the MongoDB database as a digital bookshelf where we neatly organize user data and summaries. To set it up, install MongoDB on your computer. It's like creating different shelves – one for storing user details and another for holding the summaries.

b. Create the Backend using Express.js and Node.js:

Now, let's talk about the brain behind our website – the backend. Express.js and Node.js are like a dynamic duo. Express.js is the traffic cop, guiding requests, and Node.js is the hardworking assistant, ensuring everything gets done efficiently. Together, they handle requests and communicate with the database.

c. Develop the Frontend using Angular:

Moving on to the part users interact with – the frontend. Angular helps us design a visually appealing and user-friendly interface. Think of it as crafting the front cover of a book – it's what users see and engage with. We'll create forms for users to input text and areas to display the summarized results.

d. Connect the Frontend and Backend:

Imagine the frontend and backend as two friends having a conversation. We want them to share information seamlessly. To achieve this, we'll set up a system where the user's input from the frontend travels to the backend. The backend processes it, and then the summarized result smoothly comes back to the frontend. It's like a friendly chat between the user interface and the brain behind the scenes.

Code Example
a. Set up the MongoDB Database

// Import required module
const mongoose = require('mongoose');

// Connect to MongoDB database
mongoose.connect('mongodb://localhost/summarizerDB', { useNewUrlParser: true, useUnifiedTopology: true });

// Define a schema for user data
const userSchema = new mongoose.Schema({
  username: String,
  email: String,
  // Add more fields as needed
});

// Define a schema for summaries
const summarySchema = new mongoose.Schema({
  userId: mongoose.Schema.Types.ObjectId,
  text: String,
  summary: String,
});

// Create models based on the schemas
const User = mongoose.model('User', userSchema);
const Summary = mongoose.model('Summary', summarySchema);

// Example usage:
// const newUser = new User({ username: 'JohnDoe', email: 'john@example.com' });
// newUser.save();

// const newSummary = new Summary({ userId: newUser._id, text: 'Lorem ipsum...', summary: 'Summary goes here.' });
// newSummary.save();

b. Create the Backend using Express.js and Node.js

// Import required modules
const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');

// Create Express application
const app = express();
const port = 3000;

// Connect to MongoDB database
mongoose.connect('mongodb://localhost/summarizerDB', { useNewUrlParser: true, useUnifiedTopology: true });

// Middleware for parsing JSON
app.use(bodyParser.json());

// Define routes for handling user input and summaries
app.post('/api/submitText', async (req, res) => {
  try {
    // Process the incoming text and generate a summary
    const { userId, text } = req.body;
    const summary = processTextAndGenerateSummary(text);

    // Save the summary to the database
    const newSummary = new Summary({ userId, text, summary });
    await newSummary.save();

    res.status(200).json({ success: true, summary });
  } catch (error) {
    console.error(error);
    res.status(500).json({ success: false, error: 'Internal server error' });
  }
});

// Start the server
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

// Function to process text and generate a summary (replace with your actual summarization logic)
function processTextAndGenerateSummary(text) {
  // Simplified example: Just return the first 50 characters as a summary
  return text.slice(0, 50);
}

c. Develop the Frontend using Angular

// Import required modules
import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-summarizer',
  templateUrl: './summarizer.component.html',
  styleUrls: ['./summarizer.component.css'],
})
export class SummarizerComponent {
  userInput = '';
  summary = '';

  constructor(private http: HttpClient) {}

  submitText() {
    // Send user input to the backend for processing
    this.http
      .post<any>('http://localhost:3000/api/submitText', { userId: 'user123', text: this.userInput })
      .subscribe((response) => {
        if (response.success) {
          // Update the summary on the frontend
          this.summary = response.summary;
        } else {
          console.error(response.error);
        }
      });
  }
}
