The Node.js OCR SDK supports the Invoice Splitter API.

Using this sample, we are going to illustrate how to detect the pages of multiple invoices within the same document.

Quick-Start

⚠️ Important: This API only works asynchronously, which means that documents have to be sent and retrieved in a specific way:

const mindee = require("mindee");
// for TS or modules:
// import * as mindee from "mindee";

// Init a new client
const mindeeClient = new mindee.Client({ apiKey: "my-api-key" });

// Load a file from disk
const inputSource = mindeeClient.docFromPath("/path/to/the/file.ext");

// Parse the file asynchronously.
const asyncApiResponse = mindeeClient.enqueueAndParse(mindee.product.InvoiceSplitterV1, inputSource);

// Handle the response Promise
asyncApiResponse.then((resp) => {
  // print a string summary
  console.log(resp.document.toString());
});

Output (RST):

:Mindee ID: 8c25cc63-212b-4537-9c9b-3fbd3bd0ee20
