Libraries

Used libraries

Axios for HTTP-Request handling to ensure the library works on node and web (MIT License)
isbn3 package is used to hyphenate and validate ISBN numbers (MIT License)
Cheerio will be used to scrape HTML (MIT License)
tslint, prettier and jest are used because they are pretty much industry standard

Considered but not used

JSSoup is a possible alternative to Cheerio but is not uses because Cheerio seems to be a more active project
we are not using price-finder to scrape prices from Amazon and Google because i has vulnerable dependencies

Other Technical Decisions

Unit and Component tests are merged checkout testing for more information
