Behavior targets for a version built in ReactJS:

ISBN Scanner Behavior

I load the index page:

I see:
- A 'scan barcode' button
- A link to 'Search for Book'
- A link to 'My Bookshelf'
A modal pop informs me:
- Bookshelves are stored on the device and aren't shared
  - If you open this on a phone, and your PC, they will have different shelves
  - There is an import/export shelf for this purpose
- Some book barcodes can't be used to search (UPCs)
- If the scanner fails to find your book, you can retry
- After a failure display a 'Search Book by Title' button alongside 'Retry'
I successfuly scan a book or find a book with search
- I'm given an 'Add book to my shelf' option
- Pressing the button adds the book to my 'shelf' page

I load the 'Bookshelf' page:

I see:
- A list of my books, or 'nothing here but us owls' if no books
- An 'Import' button and an 'Export' button
- Links for 'Scan Book Barcode' and 'Search for Book'
I press 'Import'
- I am allowed to choose a CSV file I previously exported to populate my shelf
- If the import fails, I get an error for the line that failed (if any)
I press 'Export'
- I recieve a CSV containing all the books on my bookshelf
My book list:
- Has a 'Remove Book from Shelf' option
  - Removes the book from my collection if there was an error or I sold it.

I load the 'Search for Book' page:

I see:
- Optional 'Title', 'Author' and 'ISBN-10 or ISBN-13' search fields
- a 'Search' button
I add information:
- I can add title, author and/or ISBN-10/13 and it searches a combination
- When I press 'Search' a table of books is populated below the search bars
The table:
- Contains book information and a link (newtab) to that book on Google Books
- A button to 'Add to Shelf'

Special Behaviors:

I scan a book already in my collection OR
I press 'Add book' on a book already in my collection
- A warning pop informs me the book is already on my shelf, I can still add it.
