Quick-Start

Using the sample below, we are going to illustrate how to extract the data that we want using the SDK.

Sample Code

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
const apiResponse = mindeeClient.enqueueAndParse(
  mindee.product.us.UsMailV3,
  inputSource
);

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

Sample Output (rST)

Standard Fields

These fields are generic and used in several products.

Basic Field

Each prediction object contains a set of fields that inherit from the generic Field class.

A typical Field object will have the following attributes:

• value (number | string): corresponds to the field value. Can be undefined if no value was extracted.

• confidence (number): the confidence score of the field prediction.

• boundingBox ([Point, Point, Point, Point]): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.

• polygon (Point[]): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.

• pageId (number): the ID of the page, always undefined when at document-level.

• reconstructed (boolean): indicates whether an object was reconstructed (not extracted as the API gave it).

A Point simply refers to an array of two numbers ([number, number]).

Aside from the previous attributes, all basic fields have access to a toString() method that can be used to print their value as a string.

String Field

The text field StringField only has one constraint: its value is a string (or undefined).
