Portfolio of Projects from the Udacity-FSND.

Successor of my first Udacity Nanodegree Intro to Programming.

est. time spent: 32 hours (including pre-courses)

Aim of the project was to build a full-stack Web App with Flask and Boostrap which enables Venues & Artists to list themselves and arrange Shows together.

Used tech stack:

• SQLAlchemy as ORM library of choice
• PostgreSQL as database
• Python3 and Flask for server language and framework
• Flask-Migrate for creating and running schema migrations
• Frontend: HTML, CSS, and Javascript with Bootstrap 3 (mainly provided by Udacity Team)

Applied concepts:

• How to use Git Bash & Github as version control tool
• Configure local database and connect it to a web application
• Create Model Schemas with columns and relationships (1:1, 1:n and N:N)
• Use SQLAlchemy ORM with PostgreSQL to query, insert, edit & delete Data
• Use WTForms to encapsulate input forms in seperate file & to allow for custom validations
• Use Boostrap as a simple to use Front End Libary and Ajax to fetch flask routes
• Create SQL-like Queries, but without any SQL syntax, only using SQLAlchemy ORM
• How to clearly structurize a larger web application in different files & folders

Using 'Flask' and 'React', created a Full-Stack App to manage questions for different categories & develop an API to power the Quiz Gameplay.

Used tech stack:

• React Components as frontend (provided by Udacity Team)
• Python3 and Flask for server language and API development
• cors to handle access to the API
• unittest for automated testing of APIs
• curl to get responses from API
• README.md to document project setup & API endpoints

Applied concepts:

• using best-practice PEP8-style to design and structur code
• test-driven-development (TDD) to rapidly create highly tested & maintainable endpoints.
• directly test and make response to any endpoint out there with curl.
• implement errorhandler to format & design appropiate error messages to client
• becoming aware of the importance of extensive project documentation & testing.

Using 'Flask' and 'Auth0', created a Full-Stack App to let Users login to Site & make actions according to their Role & Permission Sets.

Used tech stack:

• Python3 & Flask for server language and API development
• SQLAlchemy as ORM / Sqlite as database
• Ionic to serve and build the frontend (provided by Udacity Team)
• Auth0 as external Authorization Service & permission creation
• jose JavaScript Object Signing and Encryption for JWTs. Useful for encoding, decoding, and verifying JWTs.
• postman to automatize endpoint testing & verification of correct Authorization behaviour.

Deployed a Flask API to a Kubernetes cluster using Docker, AWS EKS, CodePipeline, and CodeBuild.

(Application has been teared down after successfull review to avoid incurring additional costs)

View Project.

Used tech stack:

• Docker for app containerization & image creation to ensure environment consistency across development and production server
• AWS EKS & Kubernetes as container orchestration service to allow for horizontal scaling
• aswscli to interact with AWS Cloud Services
• ekscli for EKS cluster creation
• kubectl to interact with kubernetes cluster & pods
• CodePipeline for Continuous Delivery (CD) & to watch Github Repo for changes
• CodeBuild for Continuous Integration (CI), together with pytest for automated testing before deployment

est. time spent: 20 hours (no precourses)

This is the last project of the Udacity-Full-Stack-Nanodegree Course. It covers following technical topics in 1 app:

1. Database modeling with postgres & sqlalchemy (see models.py)
2. API to performance CRUD Operations on database with Flask (see app.py)
3. Automated testing with Unittest (see test_app)
4. Authorization & Role based Authentification with Auth0 (see auth.py)
5. Deployment on Heroku (see setup.sh)
