amz-spy

Amazon Inventory Scraper

===================

Why open source this

I am in the process of open sourcing multiple of my projects/libraries that might be of help for other developers.

What does this package/lib do

It was coded with the aim to spy/scrape amz products' inventories and help users/merchants come up with new sourcing ideas.

Get started

npm install amz-spy

Available methods

scrapeAmazonProductPage(requestObject)

This method returns a promise and must be used before getAmazonInventory Info

getAmazonInventoryInfo(requestParams, productInfo)

This method returns a promise and needs to be called after scrapeAmazonProductPage

Example :

const amzSpy = require('amz-spy')
 
const requestObject = {
    url : 'THE PRODUCT URL',
    method : 'GET',
    encoding : 'binary',
    timeout : 20000,
    proxy : 'YOUR PROXY or null',
    createJar : true
}
 
amzSpy.scrapeAmazonProductPage(requestObject).then(data => {
    const requestParams = {
    	url : data.formUrl,
        form : data.postData,
        proxy : '',
        method : 'POST',
        jar : data.cookieJar
    }
    //Also returns the product info
    const productInfo = {
      productPrice : data.productPrice,
      salesRank : data.salesRank,
      numReviews : data.numReviews,
      merchantId : data.merchantId,
    }
    return amazon.getAmazonInventoryInfo(requestParams, productInfo);
}).then(data => {
    //Info returned by getAmazonInventoryInfo
    const {
    	date,
    	inventory,
      price,
      sales_rank,
      merchant_id,
      num_reviews 
    } = data
    console.log(result)
}).catch(err => {
  console.log(err)
})
