Mindee API Helper Library for Node.js

Quickly and easily connect to Mindee's API services using Node.js.

Quick Start

Here's the TL;DR of getting started.

First, get an API Key

Then, install this library:

npm install mindee

Finally, Node.js away!

Loading a File and Parsing It

Global Documents

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 it on the API of your choice
const apiResponse = mindeeClient.parse(mindee.product.InvoiceV4, inputSource);

Note: Files can also be loaded from:

A base64 encoded string:

const inputSource = mindeeClient.docFromBase64(myInputString, "my-file-name.ext")

A byte sequence:

const inputSource = mindeeClient.docFromBytes(myInputBytes, "my-file-name.ext")

A stream:

const inputSource = mindeeClient.docFromStream(myReadableStream, "my-file-name.ext")

A buffer:

const inputSource = mindeeClient.docFromBuffer(myBuffer, "my-file-name.ext")

A URL (https only):

const inputSource = mindeeClient.docFromUrl("https://my-url");

You can also load the document locally before sending it:

const inputSource = mindeeClient.docFromUrl("https://my-url");
await inputSource.init();
const localInputSource = inputSource.asLocalInputSource();

Note: Files hidden behind redirections are rejected by the server; this solution helps to circumvent that issue.

Region-Specific Documents

Region-Specific Documents use the following syntax:

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

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

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

// The IdCardV1 product belongs to mindee.product.fr, not mindee.product itself
const apiResponse = mindeeClient.parse(mindee.product.fr.IdCardV1, inputSource);

Custom Documents (docTI & Custom APIs)

Custom documents will require you to provide their endpoint manually.

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");

// Create a custom endpoint for your product
const customEndpoint = mindeeClient.createEndpoint(
  "my-endpoint",
  "my-account",
  "my-version" // will default to 1 if not provided
);

// Parse it
const apiResponse = await mindeeClient
  .enqueueAndParse(
    mindee.product.GeneratedV1,
    inputSource,
    {
      endpoint: customEndpoint
    }
  );

Handling the Return

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

    // individual pages (array)
    console.log(res.document.inference.pages);
});

Additional Options

Options to pass when sending a file to be parsed.

Page Options

Allows only sending certain pages in a PDF.

In this example we only send the first, penultimate, and last pages:

const apiResponse = mindeeClient.parse(
  mindee.product.InvoiceV4,
  inputSource,
  {
    pageOptions: {
      pageIndexes: [0, -2, -1],
      operation: mindee.PageOptionsOperation.KeepOnly,
      onMinPages: 2
    }
  });
