This is my solution to the Codecademy portfolio project entitled Final PERN App, an open-ended project that had to be built using the PERN stack.
The application had to satisfy the following requirements:
- have a front-end built using React.js
- have a server built using Node.js and Express.js
- use a PostgreSQL database to store data
- be written with the best security principles in mind
- include unit tests to ensure the integrity of the code
- use Git version control
- be developed locally
- be published on Heroku
I decided to design an app that allows Users to view all the publicly-available images taken by the Opportunity Rover during its lifetime on Mars. I wrote code that communicated with the open-source NASA Mars Rover API for several hours in order to extract all the necessary image data; I inserted the relevant data from each NASA API response to my local PostgreSQL database.
I wrote unit tests (340 in total) as I was building the app in order to ensure that the presentation and functionality of each component matched my specifications. The components used in the app are explained in the images below.
I wrote this Final PERN App using the following technologies:
- JavaScript
- React.js
- React Testing Library and Jest
- Express.js
- Node.js
- PostgreSQL
- Git and GitHub
- Command Line
- Entity Relationship Diagram (LucidChart)
- Algorithm Diagram (LucidSpark)
This Final PERN App can be viewed and interacted with:
