This sample code shows extracting attachments of PDF document using PDF Cloud Node.js SDK
import credentials from "./credentials.json" with { type: "json" };
import fs from 'node:fs/promises';
import path from 'node:path';
import { PdfApi } from "asposepdfcloud";
import { AttachmentInfo } from "asposepdfcloud/src/models/attachmentInfo.js";
async function getAllAttachments() {
const LOCAL_PATH = "C:\\Samples\\";
const LOCAL_FILE_NAME = "C:\\Samples\\Attachments\\sample_attachment.pdf";
const STORAGE_FILE_NAME = "sample_attachment.pdf";
try {
const pdfApi = new PdfApi(credentials.id, credentials.key);
const pdfData = await fs.readFile(LOCAL_FILE_NAME);
await pdfApi.uploadFile(STORAGE_FILE_NAME, pdfData);
const result = await pdfApi.getDocumentAttachments(STORAGE_FILE_NAME);
if (result.body.code === 200 && result.body.attachments) {
const attachmentList = result.body.attachments.list || [];
if (!attachmentList.length) {
console.error("No attachments found.");
return;
}
const downloadTasks = attachmentList.map(async (attachment) => {
try {
const attachmentUrl = attachment.links[0].href;
const info = await pdfApi.getDocumentAttachmentByIndex(STORAGE_FILE_NAME, attachmentUrl);
const download = await pdfApi.getDownloadDocumentAttachmentByIndex(STORAGE_FILE_NAME, attachmentUrl);
await fs.writeFile(path.join(LOCAL_PATH, info.body.attachment.name), download.body);
} catch (error) {
console.error("Failed to download attachment:", error);
}
});
await Promise.all(downloadTasks);
} else {
console.error("Failed to retrieve attachments. Status:", result.statusCode);
}
} catch (error) {
console.error("Error processing PDF attachments:", error);
}
}
