json-nl.js

// This is a simple approach to downloading the data from our API
// and processing it as JSON Object. This method is only sufficient for 
// small API responses (should work for responses below 100k results).
// If your response contains more results, try having a look at this Stack Overflow QA:
// http://stackoverflow.com/questions/15121584/how-to-parse-a-large-newline-delimited-json-file-by-jsonstream-module-in-node-j
 
// We start by getting data from our API:
let extractorRunId = "00000000-0000-0000-0000-000000000000";
let jsonFieldId = "00000000-0000-0000-0000-000000000001"; // You can get this value, by displaying https://store.import.io/store/crawlrun/${extractorRunId} in the browser, and getting the value from `json` field.
let apiKey = "YOUR_API_KEY"; // You can get it here https://import.io/data/account/
let API_ENDPOINT = `https://store.import.io/store/crawlrun/${extractorRunId}/_attachment/json/${jsonFieldId}?_apikey=${apiKey}`;
let response;
 
// We are using the Fetch API, that is only available in newer browsers (details: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API). Try this code in Newest Chrome Console.
fetch(API_ENDPOINT)
