RearrangePDF_Pages_NodeJs_Configurations.js

// This code example demonstrates how to add your client id and secret in the code.
global.clientId = '659fe7da-715b-4744-a0f7-cf469a392b73';
global.clientSecret = 'b377c36cfa28fa69960ebac6b6e36421';
global.myStorage = "";

const configuration = new groupdocs_merger_cloud.Configuration(clientId, clientSecret);
configuration.apiBaseUrl = "https://api.groupdocs.cloud";

RearrangePDF_Pages_NodeJs_Download.js

// This code example demonstrates how to download a PDF file from the cloud.
// Initialize api
var fileApi = groupdocs_merger_cloud.FileApi.fromConfig(configuration);

// Create file download request
let request = new groupdocs_merger_cloud.DownloadFileRequest("move-pages.pdf", myStorage);

// Download file
let response = await fileApi.downloadFile(request);

// Save PDF file in working directory
fs.writeFile("C:\\Files\\merger\\move-pages.pdf", response, "binary", function (err) { });

RearrangePDF_Pages_NodeJs_Move.js

// This code example demonstrates how to move pages within PDF document.
// Api initialization
let pagesApi = groupdocs_merger_cloud.PagesApi.fromKeys(clientId, clientSecret);

// Initialize MoveOptions
let options = new groupdocs_merger_cloud.MoveOptions();

// Input file path
options.fileInfo = new groupdocs_merger_cloud.FileInfo();
options.fileInfo.filePath = "sample.pdf";

// Output file path
options.outputPath = "move-pages.pdf";

// The page to move
options.pageNumber = 1;

// At which position to move
options.newPageNumber = 4;

// Create move request
let request = new groupdocs_merger_cloud.MoveRequest(options);

// Move page
let result = await pagesApi.move(request);
console.log("Document edited: " + result.path);

RearrangePDF_Pages_NodeJs_Swap.js

// This code example demonstrates how to swap pages within PDF document.
// Api initialization
let pagesApi = groupdocs_merger_cloud.PagesApi.fromKeys(clientId, clientSecret);

// Initialize SwapOptions
let options = new groupdocs_merger_cloud.SwapOptions();

// Input file path
options.fileInfo = new groupdocs_merger_cloud.FileInfo();
options.fileInfo.filePath = "sample.pdf";

// Output file path
options.outputPath = "swap-pages.pdf";

// First page number to swap
options.firstPageNumber = 2;

// Second page number to swap with
options.secondPageNumber = 4;

// Create swap request
let request = new groupdocs_merger_cloud.SwapRequest(options);

// Swap pages
let result = await pagesApi.swap(request);
console.log("Document edited: " + result.path);

RearrangePDF_Pages_NodeJs_Upload.js

// This code example demonstrates how to upload a PDF file to the cloud.
// Construct FileApi
let fileApi = groupdocs_merger_cloud.FileApi.fromConfig(configuration);
let file = 'C:\\Files\\merger\\sample.pdf';

// Read files one by one
fs.readFile(file, (err, fileStream) => {
  // Create upload file request
  let request = new groupdocs_merger_cloud.UploadFileRequest("sample.pdf", fileStream, myStorage);
  // Upload file
  fileApi.uploadFile(request);
});
