Release Unmanaged Resources of the Workbook with Node.js via C++

Aspose.Cells provides Workbook.dispose() method to release the unmanaged resources of the Workbook object. The dispose pattern is used only for objects that access unmanaged resources, such as file and pipe handles, registry handles, wait handles, or pointers to blocks of unmanaged memory. This is because the garbage collector is very efficient at reclaiming unused managed objects, but it is unable to reclaim unmanaged objects.

Workbook object now implements the System.IDisposable interface, which has a single method Workbook.dispose(). You can either call the Workbook.dispose() method directly or use the using statement to have this method called automatically.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

 // The path to the documents directory.
 const dataDir = path.join(__dirname, "data");
 const filePath = path.join(dataDir, "sample.xlsx");
 // Load the workbook which contains hidden external links
 const workbook = new AsposeCells.Workbook(filePath);

 // Create a workbook object
 const wb1 = new AsposeCells.Workbook();

 // Call the Dispose method
 wb1.dispose();

 // Call the Dispose method via a scoped approach
 (async () => {
   const wb2 = new AsposeCells.Workbook();
   // Any other code goes here
   wb2.dispose();
 })();
