This sample code shows deleting Bookmarks from PDF documents using Node.js


    import credentials from "credentials.json"  with { type: "json" };    // json-file in this format: { "id": "*****", "key": "*******" }
    import fs from 'node:fs/promises';
    import path from 'node:path';
    import { PdfApi } from "asposepdfcloud";

    const configParams = {
        LOCAL_FOLDER: "C:\\Samples\\",
        PDF_DOCUMENT_NAME: "sample.pdf",
        LOCAL_RESULT_DOCUMENT_NAME: "output_sample.pdf",    
        DROP_BOOKMARK_PATH: "/1"
    };

    const pdfApi = new PdfApi(credentials.id, credentials.key);

    const pdfBookmarks = {
        async uploadDocument() {
            const pdfFilePath = path.join(configParams.LOCAL_FOLDER, configParams.PDF_DOCUMENT_NAME);
            const pdfFileData = await fs.readFile(pdfFilePath);
            await pdfApi.uploadFile(configParams.PDF_DOCUMENT_NAME, pdfFileData);
        },

        async downloadResult() {
            const changedPdfData = await pdfApi.downloadFile(configParams.PDF_DOCUMENT_NAME);
            const filePath = path.join(configParams.LOCAL_FOLDER, configParams.LOCAL_RESULT_DOCUMENT_NAME);
            await fs.writeFile(filePath, changedPdfData.body);
            console.log("Downloaded: " + filePath);
        },

        async deleteBookmark(){
            const dropResult = await pdfApi.deleteBookmark(configParams.PDF_DOCUMENT_NAME, configParams.DROP_BOOKMARK_PATH);
            
            if (dropResult.body.code == 200) {
                console.log("Bookmark '" + configParams.DROP_BOOKMARK_PATH + "' successfully deleted!");
                return true;
            }
            else
                throw new Error("Unexpected error : can't get bookmarks list!!!");
        },
    };

    async function main() {
        try
        {
            await pdfBookmarks.uploadDocument();
            await pdfBookmarks.deleteBookmark();
            await pdfBookmarks.downloadResult();
