How to update an AcroForms via Node.js SDK

The provided JavaScript code is designed to update form fields in a PDF document using the Aspose PDF Cloud API. It imports necessary modules, reads a local PDF file, uploads it to the cloud, and then updates specific fields in the PDF. The function updateFormFields encapsulates the entire process, handling both file operations and API interactions. It also includes error handling to manage potential issues during file reading and API requests.

In order to update an AcroForm to PDF, we’ll use Aspose.PDF Cloud Node.js SDK. This Cloud SDK assists Node.js programmers in developing cloud-based PDF creator, annotator, editor, and converter apps using Node.js programming language via Aspose.PDF REST API. Simply create an account at Aspose for Cloud and get your application information. Once you have the App SID & key, you are ready to give the Aspose.PDF Cloud Node.js SDK.

Package Manager Console Command

        field.type = FieldType.Text;
        field.values = ["James"];
        field.rect = new Rectangle(125, 735, 200, 752);
        let fields = new Fields();
        fields.list = [field];
        try {
