Nodejs, npm, Javascript Logo dark background

JavaScript is really popular language for building web based frontend application, even before the presences of Nodejs. Now there's Nodejs, with it not only you can just build front end application, now you can build any kind of application using Javascript with Node Js. With it's package manager called NPM (node package manager), the biggest collections of libraries in programming world, you will build a robust application using Nodejs with its huge collections of libraries written in Javascript, you can just search whatever dependency you need, pick it, use it whichever for free.

Now if you are a beginner programmer who do not know how to get started doing Javascript programming with package manager. This is without further ado let's just start on how to install Nodejs into your platform.

1. Install Nodejs

You need to install Nodejs to use NPM, to have Nodejs installed on your Windows computer. You can download Nodejs installer from nodejs.org, click on the installer and just follow the default configuration.

If you are using Linux or MacOS, you don't need to download zip archive of Nodejs because usually for most Linux distributions already have Nodejs on their repositories. Using Linux especially for Ubuntu, just open a terminal and type in:

sudo apt-get install nodejs

For Mac Os, using brew instead:

brew install node

Just wait for the process to finish.

2. Add npm to path

After the installation process of Nodejs is finished, if you try typing npm on terminal or cmd, you will get an error telling you that npm is not in your path. You need to put npm to your path by following the below instructions.

a. For Windows
- On windows, by default npm will be installed under C:\Program Files\nodejs\
- Press windows button, search for edit system environment, open that program.
- Environment variables > system variables > edit Path > New, and then add C:\Program Files\nodejs\ > OK and Apply
- Then close the cmd and reopen it, now if you type npm, it is not valid command but at least now you have npm on your path. You've successfully installed nodejs.

b. Linux/Ubuntu/Mac OS users
To add NPM on your Ubuntu machine, simply by using apt package manager:

sudo apt-get install npm

If you are using Linux but not Ubuntu, I am so sorry because I've never used Linux other than Ubuntu, basically just replacing apt-get with  yum if you are using Fedora for example.

For Mac OS you don't have to install, npm is already included with Nodejs.

So that's how simple it is to install Nodejs for you to begin your Journey developing application using Javascript. If you already have Nodejs and NPM on your terminal, you can do a simple test for example to test Nodejs, just type node and then follow by your Javascript example code:

node
console.log("Hello World!");


In the future you will use NPM as package manager, to add, remove, upgrade your Javascript dependencies. The syntax you need to remember that you will be using it frequently is for example installing and removing dependencies, the syntax is as follows:

npm install the-dependency-name
npm uninstall the-dependency-name

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database. UPDATE mysql.user SET Password=PASSWORD('1234') WHERE User='root'; The solutions for MySQL Error1348 So you can not update a user password using Update commands, to update the password, use ALTER commands instead. like the following. ALTER USER 'root'@'localhost' IDENTIFIED BY '1234'; And then you need to do the flush privileges to commit previous queries (that alter command above) into the system, simply do like this. flush privileges; So now you have your root with password 1234. Although it is recommended to

How To Create Spring Boot Project Using Netbeans

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab. Look for the "Nb SpringBoot" plugin, then install and activate it. 2. Create a New Spring Boot Project: After restarting Netbeans IDE, you can create a new project with Spring Boot. Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl
