Bookmancy

a brilliant new way to search for book prices

Overview

Bookmancy is a small module to scrape abebooks.com search results and ebay book search results for consumption in a node environment.

`abe` - AbeBooks search

Methods

`search({author, title, publisher, format, year})`

title - String - The title of the book
author - String - The author or editor of the book. Basically anything that a seller would potentially put as the author.
publisher - String - The name of the publisher
format - String - options include hardback, hardcover, softcover, paperback, h, p
year - Number - Four digit year, filters books published <=year

Returns

[
    <BookResult>...
]

Example

const bookmancy = require('bookmancy');
bookmancy.abe.search({author: 'August Derleth', publisher: 'Mycroft'})
    .then(results => {

    });

`searchWithUrlInResponse({author, title, publisher, format, year})`

Argument options are the same as above, but the resolved value is different. It will include the URL that was scraped in case you wish to actually view the page for yourself in your app.

Returns

{
    url: 'https://abebooks...',
    retults: [
        <BookResult>...
    ]
}

Example

const bookmancy = require('bookmancy');
bookmancy.abe.searchWithUrlInResponse({author: 'August Derleth', publisher: 'Mycroft'})
    .then(results => {
        
    });

ebay - ebay Search

REQUIRES ebay API key

All ebay requests take place with their actual API. So you will need to register to add an application and get your keys. Once you have your key you will need to be sure to include the key in your project's .env file:

EBAY_API_KEY=xxxxxxxxxxxxxxxxxxx

Failure to include this key will result in all search calls rejecting with an error highlighting that this step must be completed.

Methods

`search(query)` - Search both sold and live listings

This will search two APIs. The sold items, and current items API will be merged and sorted by price. To get specific results use one of the following methods.

query - String - Generic query. Best bet for ebay right now. No relevant metrics are tracked/searchable (to my knowledge) in the ebay API.

Returns

[
    <BookResult>...
]

Example

const bookmancy = require('bookmancy');
bookmancy.ebay.search('August Derleth Mycroft')
    .then(results => {
        
    });

`searchLiveListings(query)`

Same as search, but only for current listings. Caution: this usually has unrealistically high prices at the top of the list. Usually we use this one to verify a book is hard to come by.

`searchSoldListings(query)`

Same as search, but only for listings that have completed with sales. Note that the price on the result might not necessarily be correct. (e.g. Buy It Now vs. Accepted Offer price) But this generally is good enough to know how popular something is and gives a very good idea of how easy it should be to flip.
