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.v1.Client({ apiKey: "my-api-key" });

// Load a file from disk
const filePath = "/path/to/the/file.ext";
const inputSource = new mindee.PathInput({ inputPath: filePath });

// Parse the file
const apiResponse = mindeeClient.parse(
  mindee.v1.product.InvoiceV4,
  inputSource
);

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

You can also call this product asynchronously:

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

// Init a new client
const mindeeClient = new mindee.v1.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.v1.product.InvoiceV4,
  inputSource
);

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

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.

AddressField

Aside from the basic BaseField attributes, the address field AddressField also implements the following:

• streetNumber (string): String representation of the street number. Can be null.

• streetName (string): Name of the street. Can be null.

• poBox (string): String representation of the PO Box number. Can be null.

• addressComplement (string): Address complement. Can be null.

• city (string): City name. Can be null.

• postalCode (string): String representation of the postal code. Can be null.

• state (string): State name. Can be null.

• country (string): Country name. Can be null.

The value field of an AddressField should be a concatenation of the rest of the values.

Amount Field

The amount field AmountField only has one constraint: its value is a number (or undefined).

Classification Field

The classification field ClassificationField does not implement all the basic Field attributes. It only implements value, confidence and pageId.

A classification field's value is always a string.

Company Registration Field

Aside from the basic Field attributes, the company registration field CompanyRegistrationField also implements the following:

• type (string): the type of company.

Date Field

Aside from the basic Field attributes, the date field DateField also implements the following:

• dateObject (Date): an accessible representation of the value as a JavaScript object.

Locale Field

The locale field LocaleField implements the value, confidence and pageId from the base Field attributes.

In addition, it comes with these specific attributes:

• language (string): ISO 639-1 language code (e.g.: en for English). Can be undefined.

• country (string): ISO 3166-1 alpha-2 or ISO 3166-1 alpha-3 code for countries (e.g.: GRB or GB for "Great Britain"). Can be undefined.

• currency (string): ISO 4217 code for currencies (e.g.: USD for "US Dollars"). Can be undefined.

Payment Details Field

Aside from the basic Field attributes, the payment details field PaymentDetailsField also implements the following:

• accountNumber (string): number of an account, expressed as a string. Can be undefined.

• iban (string): International Bank Account Number. Can be undefined.

• routingNumber (string): routing number of an account. Can be undefined.

• swift (string): the account holder's bank's SWIFT Business Identifier Code (BIC). Can be undefined.

String Field

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

Taxes Field

Tax

Aside from the basic Field attributes, the tax field TaxField also implements the following:

• rate (number): the tax rate applied to an item can be expressed as a percentage. Can be undefined.

• code (string): tax code (or equivalent, depending on the origin of the document). Can be undefined.

• base (number): base amount used for the tax. Can be undefined.

• value (number): the value of the tax. Can be null.

Currently TaxField is not used on its own, and is accessed through a parent Taxes object, an array-like structure.

Taxes (Array)

The Taxes field represents an array-like collection of TaxField objects. As it is the representation of several objects, it has access to a custom toString() method that can render a TaxField object as a table line.

Specific Fields

Fields which are specific to this product; they are not used in any other product.

Line Items Field

List of all the line items present on the invoice.

A InvoiceV4LineItem implements the following attributes:

• description (string): The item description.

• taxRate (number): The item tax rate in percentage.
