HTTP response status codes

HTTP response status codes

HTTP status codes are essential for communication between the client-side and server-side components of your application.
HTTP response status codes indicate whether a specific HTTP request has been successfully completed. Responses are grouped in five classes:

Informational responses (100 – 199)
Successful responses (200 – 299)
Redirection messages (300 – 399)
Client error responses (400 – 499)
Server error responses (500 – 599)

Informational responses (100 – 199)
Successful responses (200 – 299)

Redirection messages (300 – 399)
Client error responses (400 – 499)

Server error responses (500 – 599)

Types of Node Modules

Types of Node Modules
linkedin

There are three main types of Node modules that you will work with as a Node.js developer. They include the following.

Built-in modules
Local modules
Third-party modules

Built-in Modules

Node.js comes with some modules out of the box. These modules are available for use when you install Node.js. Some common examples of built-in Node modules are the following:

http
url
path
fs
os

Local Modules

When you work with Node.js, you create local modules that you load and use in your program.

Third-Party Modules

A cool thing about using modules in Node.js is that you can share them with others. The Node Package Manager (NPM) makes that possible.

Mern Stack

athul jain — Tue, 09 Jan 2024 03:24:01 +0000

MERN stack comprises the following technologies that allow for faster application development:

MongoDB: A cross-platform document-oriented database program
Express.js: A web application framework for Node.js
React: JavaScript library for building user interfaces
Node.js: An open source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a browser

Password hashing

athul jain — Fri, 08 Dec 2023 06:07:34 +0000

Password hashing involves transforming a password into alphanumeric characters using specific algorithms. Hashing proves advantageous when malicious actors compromise data. With hashing, the obtained data is in hash format, rendering it unintelligible. Popular algorithms for password hashing encompass bcrypt and SHA.

In this article, the spotlight will be on utilizing bcrypt for password hashing in Node.js. Here’s an example of hashing plain text:
hash('HeypasswordIsSafe@') = 1b21hb2hb1u2gu3g2fxy1v2ux1v2y3vu12g4u3ggvgu43598sa89da98sd79adshuavusdva9sdguasd

props and context - react.js

athul jain — Mon, 04 Dec 2023 06:32:54 +0000

"context" and "props" are concepts used to manage and pass data between components.

Props (Properties):

** Props are a mechanism for passing data from a parent component to a child component in a unidirectional flow.**

Direction of Data Flow: Data flows from parent to child components only.
Usage: Parent components pass data as props to child components, and child components receive and use these props.
Immutability: Props are immutable, meaning that child components cannot directly modify the props they receive from their parent.

Context:

Context provides a way to share values like themes, authentication status, etc., between components without explicitly passing them through props.

Direction of Data Flow: Context allows for more flexible data flow, as it enables sharing data with components that are not direct parent or child relationships.
Usage: Context is used when you have data that needs to be accessed by many components at different levels in the component tree.
** Immutability:** While context itself is not inherently immutable, the values provided through context can be treated as immutable to prevent unexpected behavior.

Node js - 5 Features

athul jain — Fri, 01 Dec 2023 07:05:30 +0000

Node.js is a runtime environment that allows you to execute JavaScript code outside a web browser. It is built on the V8 JavaScript runtime and provides a way to run JavaScript on the server side. Here are five key features of Node.js in simple terms:

Asynchronous and Event-Driven:

Node.js is designed to handle asynchronous operations efficiently. It uses a non-blocking, event-driven architecture.

Fast Execution:

Node.js is known for its fast execution of code.

Single Programming Language (JavaScript):

Node.js allows developers to use a single programming language (JavaScript) for both server-side and client-side scripting.

NPM (Node Package Manager):

Node.js comes with a powerful package manager called NPM.

Scalability:

Node.js is designed to be scalable, making it suitable for building applications with varying levels of traffic.

React js props

athul jain — Fri, 10 Nov 2023 02:48:59 +0000

props (short for properties) are used to pass data from a parent component to a child component. They are like function arguments, allowing you to configure and customize a child component by providing specific data or attributes. Props are essential in building reusable and dynamic components as they enable components to receive and display different data, making the application more flexible and easier to maintain. They facilitate the flow of data within the component tree, allowing for a more modular and scalable application structure.
