NODE JS

WHY NODE JS ???

WHAT IS NODE JS

• Node.js is open-source and cross-platform JavaScript runtime-environment.

• Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser.

• A Node.js app is run in a single process, without creating a new thread for every request.

• Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking.

• The default package manager for Node.js is npm.

• JavaScript is for browser and Node.js is to run JS code outside browsers i.e servers.

INSTALLATION OF NODE

• There are alot of way's to install Node.js but we will install via official website.

• After successfully installation don't forget to run these commands for confirmation (node --version and npm --version)

LITTLE BIT ABOUT NPM

• npm is Node Package Manager.

• npm is the world's largest Software Registry.

• The registry contains over 800,000 code packages.

MY ENVIRONMENT SETUP

• I'm in love with Linux (Currently using Mint) , If you interested to learn more about Linux don't forget to read my article.

• I'm in love with VScode IDE (Integrated Development Environment).

• I have wrote a vscode extension which converts markdown file text to urdu (GITHUB LINK).

MORE INTO LINUX

  LETS START DIGGING 

• We will write a complete router-based program by Node.js with Express.js framework.

• We will write a simple program by using Node.js.

  MY PROJECTS PLAYLIST 

  MORE INTO JAVASCRIPT

DOCKER

WHY DOCKER ???

WTH IS DOCKER

• Docker is a platform for developers to build, run, and share applications with containers.

• The use of containers to deploy applications is called containerization.

• Containerization is increasingly popular because containers are: Flexible, Lightweight, Portable, Loosely coupled, Scalable and Secure

• Fundamentally, a container is nothing but a running process, with some added encapsulation features applied to it in order to keep it isolated from the host and from other containers.

IMAGE & CONTAINER

• An image includes everything needed to run an application - the code or binary, runtimes, dependencies.

• Above is the image of zayn malik (docker image) what if he get out of this image and say Hi (docker container)

DOCKER HUB

• You can find images from DockerHub.

• See hello world image from DockerHub.

• Then you can run container from that image.

  LETS START DIGGING 

• I hope you guy's have already installed Docker on your system.

• Let's run our first container.

• Don't Use Docker Toolbox please , it is depreciated.

TASK

CONTAINER ORCHESTRATION

• Container orchestration is the automatic process of managing or scheduling the work of individual containers for applications based on microservices within multiple clusters.

• The widely deployed container orchestration platforms are based on open-source versions like Docker Swarm.

• The word orchestration is dervied from orchestra.

• Container orchestration has helped to achieve microservices and microfrontend architecture.

  LETS SEE THE CODEBASE FOR GETTING IDEA OF CONTAINER ORCHESTRATION

MICROSERVICES

ARCHITECTURE

WHAT IS ARCHITECTURE

• Software architecture refers to the fundamental structures of a software system and the discipline of creating such structures and systems.

WHY MICROSERVICES ???

MONOLITHIC ARCHITECTURE

• Monolith means composed all in one piece.

• Monolithic architecture is system as a whole.

MICROSERVICES ARCHITECTURE

Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of services that are :

• Highly maintainable and testable
• Loosely coupled
• Independently deployable
• Organized around business capabilities
• Owned by a small team

MICROSERVICES VS MONOLITHIC

MICROFRONTEND

ARCHITECTURE

MICROFRONTEND

• Extending the microservice idea to frontend development.

• Techniques, strategies, and recipes for building a modern web app with multiple teams that can ship features independently.

• When we develop microservices architecture we can easily see that our frontend is now monolithic (It cause alot of probelms).

• After micro frontend now we can easily work in pairs with a team of microservices.
