Aspose.Diagram Cloud SDK for Node.js assists cloud platform developers to quickly build Microsoft Visio file creation and manipulation cloud-based applications in Node.js. Aspose.Diagram Cloud SDK for Node.js enables your cloud application end-users to read Microsoft Visio files situated on the cloud, view cloud Visio files and convert from Visio formats to other supported formats without installing Microsoft Visio or any other software. Aspose.Diagram Cloud SDK for Node.js can be used under an MIT license and works as a wrapper around the robust Aspose.Diagram REST API. The SDK supports advanced functionalities for manipulating Visio diagrams on the server, including creating new diagrams, reading existing drawings, saving Visio files to other formats, exporting to PDF, flowchart layout, auto-fit diagrams, inserting shapes, copying shapes between diagrams, rotating shapes, changing shape positions, connecting sub‑shapes, converting a specific shape, and much more. Using just a few lines of Node.js code, developers can export Microsoft Visio files (VSD, VSDX, VSS, VSSX, VTX, VDX, VDW, VST, VSTX, and VSX) to a wide variety of formats including XAML, SWF, PDF, XPS, BMP, JPEG, TIFF, EMF, SVG, and PNG.
