Namaste Node.js

• In Season 01 (Namaste_Nodejs), we will explore Node.js in depth and understand how the whole ecosystem works. We will see how JS Engine and libuv makes Node.js even more powerful.

• In Season 02 (DevTinder), we will build real world project and explore Express.js and MongoDB while building everything right from scratch.

Waterfall Model (SDLC - Software Development Life Cycle)

1. Requirements (Project Manager + Designer) \
2. .......└── Design (Senior Engineer, Engineering Manager)\
3. ...............└── Development (SDE1, SDE2 - Software Development Engineer)\
4. .........................└── Testing (SDET - Software Development Engineer in Test)\
5. ..................................└── Deployment (Dev Team, DevOps)\
6. ............................................└── Maintainance (Maintainers)

Monolith vs MicroServices

Monolith - Single Server (Frontend, Backend, Admin, Dashboard, Emails, Analytics)

MicroServices - Many Server (Frontend, Backend, Admin, Dashboard, Emails, Analytics)

Pros,Cons	Monolith	MicroServices
Dev Speed	Slow	Fast
Code Repo	Single Repo	Many Repo
Scalability	Hard	Easy
Deployment	Very Slow	Very Fast
Tech Stack	Single Tech	Multy Tech
Infra Cost	Low	High
Complexity	Bad	Good
Fault Isolation	Fast	Slow
Testing	Easy	Hard
Ownership	Single	Many
Maintainence	Easy	Hard
Rewamps	Bad	Good
Debugging	Easy	Hard

What are we going to build in DevTinder?

Use Micro Services

• Frontend - React.js
• Backend - Node.js
