Begin by cloning the project, and add a file named firebase.txt to the root directory. Paste the Firebase API key (provided in the submission email) into firebase.txt.
To start the project, run the following terminal commands:
npm install
npm start
You can now visit http://localhost:8080/ to explore the app.
To run tests, use the command npm test
I decided to use React to build my components, Redux to manage state, and Firebase to store the book data, which in hindsight may have been overkill. Having no experience with calling Firebase from a React app, I used this tutorial to get started. While it was great to go through this setup process by scratch, I realized later that the state is not particularly complex, and I could have made an equally functional app without including Redux.
I added React Router to handle navigation. It made short work of incorporating routing logic to manage my views, but again I found myself questioning my decision to employ Redux. Since the state ended up being mostly controlled by routes, Redux proved to be a lot of extra setup for minimal gain. However if I look at this as a minimum viable product that will grow in complexity over time, perhaps Redux is not superfluous.
My strategy with CSS was to let Bootstrap do the heavy lifting, with a few resets and custom styles to add my own flair. I particularly appreciate how Bootstrap makes grid layouts and forms so simple. I achieved a sort of rudimentary name-spacing by wrapping my component css in class names matching the component. I find this helps prevent class name conflicts in larger apps, and adds a little extra specificity in case I'm trying to override Bootstrap's rules.
I chose Enzyme to test my React components with Jest as a test runner. This was my first time using Jest, and I would like to spend more time exploring it, particularly the snapshot functionality, but I did not have time to get into that here.
The biggest lesson learned was that starting an app from scratch is unnecessary and unwise. I learned quite a bit from struggling through my own webpack configuration and adding a test suite, so I can't say I would have done it differently, but knowing what I know now I would like to start with more scaffolding. Adding my dependencies by hand meant I was bound to forget something (like linting!), which would have been immediately available had I started with Facebook's Create React App.
This app is definitely not ready for the production. I would have loved to include ESLint, form validation, database authentication, and some slick animations. Given more time, I would also like to break my markup into more succinct components for better readability, testability and reusability.
