This simple library parses DOM Document objects of Mercari pages in to machine friendly JSON output. It is mainly intended to be ran in the browser right on the page itself but could also be used in node by using something like jsdom.

npm install git+https://github.com/louistio/mercari-parser.git --save

Assuming you have access to a compliant Document object of a Mercari item page, this is how you use it:

import { MercariItemParser } from 'mercari-parser';

const item = new MercariItemParser(document).parse();

Resulting item will look like:

{
  "version": "2",
  "id": "...",
  "title": "...",
  "description": "...",
  "price": "...",
  "shipping": "...",
  "date": "...",
  "imageUrl": "https://(...).jpg",
  "seller": {
    "userId": "...",
    "username": "...",
    "profile": "https://(...)/"
  }
}
