Concepts Covered in this Video

 

Building a Web Application – Build a web application using the GCOMP document in LabVIEW NXG.
How to create multiple top-level WebVIs – Create multiple top-level WebVIs by selecting them in the GCOMP document. This will result in a distinct HTML file and URL for each top-level VI. Visit GitHub for more examples showing how to create multiple web pages from multiple top-level WebVIs.
Running the Web Application in any modern browser – Run the web application in any modern browser by right-clicking on the web application in SystemDesigner and choosing “Run”. This starts a compilation of the application and runs it in a browser when complete.
Permanently hosting on the NI Web Server – Copy the entire build output of the project, located in the Builds directory of the LabVIEW NXG project on disk, and paste it in the htdocts directory at C:\Program Files\National Instruments\Shared\Web Server\htdocs . Open a web browser and navigate to http://localhost:80/WebApp_Web%20Server/index.html . The port number and specific naming of the URL may change based on the NI Web Server settings and title of the project. Follow this same procedure for hosting the web application on any third-party web server.
