What differences between Dependency and DevDependency in package.json

-
NPM , NodeJS, JavaScript, Logo, Icon

Differences of devDependency and dependency are devDependency we use for just development process , dependency in the other hand will be included or transpired into the minification process Javascript files that were gonna deploy it for our run time application.

devDependency more into tools for make us easy on the development process of our application. For example some of command line tools such as angluar-cli or react-script. Also testing tools like Chai, Mocha, Enzyme.

Dependency will be included or transpiled, meanwhile devDependency is not.

Babel, ESLint is example of devDependency.

React, Redux, Express, and Axios is example of dependency that will be use on run-time.

I mean you don't need to learn that much serious about the differences, it's just tooling stuff, don't think about any of that too seriously, don't lead you into premature optimization. When i started coding i never thought any of that thing, i mean as long as you can start printing the traditional Hello World using that tool, you can just start from that time and building things that matter.

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.

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...
