    import { PdfApi } from "asposepdfcloud";

    const configParams = {
        LOCAL_FOLDER: "C:\\Samples\\",
        PDF_DOCUMENT_NAME: "sample.pdf",
        LOCAL_RESULT_DOCUMENT_NAME: "output_sample.pdf",
        PAGE_NUMBER: 2,     // Your document page number...
    };

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

    const pdfPages = {
        async uploadDocument () {
            const fileNamePath = path.join(configParams.LOCAL_FOLDER, configParams.PDF_DOCUMENT_NAME);
            const pdfFileData = await fs.readFile(fileNamePath);
            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 deletePage () {
            const resultPages = await pdfApi.deletePage(configParams.PDF_DOCUMENT_NAME, configParams.PAGE_NUMBER);

            if (resultPages.body.code == 200) {
                console.log("Page #" + configParams.PAGE_NUMBER + " - deleted!");
                return true;
            }
            else
            console.error("Unexpected error : can't get pages!!!");
        },

    }

    async function main() {
        try {
            await pdfPages.uploadDocument();
            await pdfPages.deletePage();
            await pdfPages.downloadResult();
        } catch (error) {
            console.error("Error:", error.message);

Work with the Pages in PDF via Node.js SDK

​​Removing pages from a PDF is a common task that serves multiple purposes, enhancing both the functionality and security of the document. PDFs can become unwieldy when they contain unnecessary or redundant pages, leading to larger file sizes. By removing these superfluous pages, the overall file size is reduced, making the document more manageable for storage and quicker to upload or download. Over time, documents may accumulate outdated or irrelevant information. Removing such pages ensures that the content remains current and pertinent to the intended audience.
