Node.js REST API for PDF File Creation & Conversion

Getting Started with Aspose.PDF Cloud Node.js SDK

Before we dive into coding, you'll need to install the SDK and set up the environment. You can easily install the Aspose.PDF Cloud Node.js SDK using NPM, please use the following command for a smooth installation.

npm install asposepdfcloud 

You can also download the library directly from Aspose.PDF product page

Creating a PDF Document via REST API

Aspose.PDF Cloud Node.js SDK enables software developers to create cloud-based applications for working with PDF documents. One of the simplest tasks these cloud-based PDF applications can do is to create a new PDF document dynamically with ease. Developers can define various parameters such as add new page, define page size, insert new image, text content, and other elements. The following example shows how to create new PDF document and add new page or text to it inside Node.js applications.

const pdf = require('aspose-pdf-cloud');

// Create a new PDF file
const pdfDoc = new pdf.Document();

// Add a page to the PDF file
const page = pdfDoc.addPage();

// Add some text to the page
page.paragraphs.push(new pdf.Paragraph('Hello, World!'));

// Save the PDF file to a file
pdfDoc.save('output.pdf');

Convert PDF to Various Formats in Node.js

Cloud-based PDF applications often need to convert PDFs into other formats for different use cases like editing, viewing, merging, sharing and so on. Aspose.PDF Cloud Node.js SDK supports conversion between PDF and various other file formats such as Word, Excel, PowerPoint, XPS, HTML, XML, and images. This feature is particularly useful when you need to export PDF content to other file types for editing or sharing. Here is an example that shows, how software developers can convert a PDF file to JPEG file format inside Node.js applications.

const { PdfApi } = require("asposepdfcloud");
const { PdfAType } = require("asposepdfcloud/src/models/movieAnnotation");
pdfApi = new PdfApi("XXXX", "XXXXXXX")
console.log('running example');
PdfApi.getPageConvertToJpeg("4pages.pdf", 1, null, null, null)
    .then((result) => {
        console.log(result.response);
    });

Extract Content from PDF via Node.js API

Extracting data from a PDF is useful for building applications that require content analysis, searching, or text mining. With Aspose.PDF Cloud Node.js SDK, software developers can extract text or images from specific pages or the entire document with just a couple of lines of JavaScript code. This is essential for applications that require data analysis or content reusability. Here is an example that shows how users can extract text from a PDF document inside Node.js applications.

 async function extractTextFromPdf() {
    const response = await pdfApi.getTextExtract("sample.pdf", 1);
    console.log("Extracted text from PDF:", response);
}

extractTextFromPdf();

Merge Multiple PDFs inside Node.js Apps

In business workflows, merging multiple PDFs into a single file is a common requirement. The ability to merge several PDF documents into one is another valuable feature of the Aspose.PDF Cloud Node.js SDK. Using the REST API, Software developers can easily load and merge multiple documents into one inside Node.js applications. This is useful for creating comprehensive reports or compiling related documents. Here is an example that shows how software developers can merge multiple PDF documents inside Node.js applications.

 async function mergePdfs() {
    const filesToMerge = ["doc1.pdf", "doc2.pdf"];
    await pdfApi.putMergeDocuments(filesToMerge);
    console.log("PDF documents merged successfully!");
}

mergePdfs();
