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.

Spring Kafka - how to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Kafka is an asynchronous messaging queuing system, but when you have a case in your project that you need to have the result immediately from another service you can do that quite easily. Kafka from the client side produces a message to the server side, then waiting for the server to return back the message exactly what the client wants. It’s identified in the kafka header request named KafkaHeaders.CORRELATION_ID and a topic where the server should send. If the server side produces the same correlation id to the same topic in the request, then the client side will catch that message as its reply. Although you can work with kafka from a different framework and language other than Java and Spring. Here’s in this example i just specifically giving the example of sending and replying kafka messages using Spring Boot. The Project Overview The client-project will send a string message to the server-project over kafka, then the server-project wil

flutter button left text Developing a flutter UI is very difficult for a beginner or I think any other technology it’s very intimidating for a starter. I remember my first time trying to make a button in Flutter that had left aligned text in it. I spent a lot of time on how to make it but never made it. Once you are getting familiar with flutter widget or component blocks, you can apply whatever style you want for your app. In html you can just do something like <button style=”text-align:left”>Text</button> but in flutter it is a bit tricky. So here I provide an example on how you can align text inside a flutter button to the left. Flutter button with left align text import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, visualDe
