provide amazon buy option

• conclusion : I am not able to implement this feature as the only way for me to search book on amazon is throught Amazon Product API which required an Associated Account(Required manual approval from Amazon reps which is impossible to complete in 3-4 hours)
• Here is how I understand the problem and resource gathered to help me solve the problem
  1. resource: https://webservices.amazon.com/paapi5/documentation/quick-start/using-sdk.html
  2. install deps required on Node.js example project
  3. complete necessary configuration (access_token, secret_key, ...etc)
  4. set searchItemsRequest['Keywords'] = 'Harry Potter'(book title)
  5. searchItemsRequest['SearchIndex'] = 'Books';
  6. read data from Promise api.searchItems(searchItemsRequest)
  7. extract page link from the json
