In this blog, we will provide a roadmap to guide you on your journey to becoming a web developer in 2022. The Three Paths in Web Development There are three main paths in web development that you can choose from:...
Learn how to create an interactive Node.js Command Line Interface (CLI) program by utilizing the readline module in Node.js. Making a Node.js CLI program interactive To make a Node.js CLI program interactive, Node provides the readline module from version 7 onwards. This module allows you to retrieve input from a readable stream, such as process.stdin, line by line, which is typically the terminal input during the execution of a Node program....
In a Node.js application, you can accept arguments from the command line by following these steps: When invoking your Node.js application from the command line, you can pass any number of arguments. For example: node app.js Arguments can be standalone values or have a key-value pair format. To retrieve the command line arguments in your Node.js code, you can use the process object provided by Node.js. This object exposes an argv property, which is an array containing all the command line arguments....
If you’re a developer, you need to know about Airtable and its powerful API. Airtable is a unique tool that combines the simplicity of a spreadsheet with the functionality of a database. It provides an intuitive interface for creating and managing databases, with the flexibility and ease of use of a spreadsheet. With Airtable, you can easily update your records, even from a mobile app. Perfect for Prototyping and MVPs But Airtable is much more than a fancy spreadsheet....
Overview of the Arduino Electronics Platform Arduino, a groundbreaking technology in the amateur electronics ecosystem, has revolutionized the way people learn and interact with electronics. Unlike traditional electronics studies, Arduino brought fun and ease to the learning process, making it accessible to beginners. This Italian-born marvel has created an entire industry and movement, known as the makers movement. By being a completely open-source platform, Arduino has gained immense popularity, allowing individuals and companies to build their own Arduino clones and contribute to its ever-growing ecosystem....
In this article, we will walk you through the process of building an HTTP server using Node.js. This HTTP server will serve as a basic “Hello World” application using the Node.js introductory code. const http = require('http') const hostname = 'localhost' const port = 3000 const server = http.createServer((req, res) => { res.statusCode = 200 res.setHeader('Content-Type', 'text/plain') res.end('Hello World\n') }) server.listen(port, hostname, () => { console.log(`Server running at http://${hostname}:${port}/`) }) Now, let’s analyze the code step by step....
In this blog post, we will explore different methods to check if a file exists in the filesystem using Node.js and the fs module. We will cover both synchronous and asynchronous approaches. Using fs.existsSync() The easiest way to check if a file exists in Node.js is by using the fs.existsSync() method. This method is synchronous, which means it will block the program until the file’s existence is determined. const fs = require('fs'); const path = '....
When it comes to building a new app, you are faced with a decision: stick to what you already know or venture into unfamiliar territory. It’s a dilemma that many developers encounter, as they navigate between becoming a total expert in one technology or having a broader understanding of various technologies. Opting for the stack you know best, such as sticking with React if you are already familiar with it, may seem like the safest and most convenient choice....
Cross-Origin Resource Sharing (CORS) is an essential mechanism that enables communication between clients and servers, even if they are on different domains. Normally, JavaScript applications running in the browser can only access HTTP resources on the same domain that serves them. However, CORS provides a way to allow connections to other servers. By default, certain resources like images, scripts, and styles can be loaded from different origins. However, requests made using XHR or Fetch to a different domain, subdomain, port, or protocol will fail unless the server implements a CORS policy....
How to create an Electron Node.js desktop application using create-react-app 2021 UPDATE: I highly recommend using electron-react-boilerplate instead of the approach described in this post Table of Contents Install Node.js if you haven’t already Move to your development folder Create react app Add electron Install foreman to allow executing the app from command line Install the create-react-app dependencies Configure eslint Enough with the setup! Start up Thanks to When I first used Electron in 2015 it was not yet clear that it would be so pervasive in modern apps, and I was kind of shocked by the resulting app size....
