I need a document viewer component (word , excel and ppt file) for our angular application. I have used a web api service to get files in blob URL to preview files.
its support blob urls because we do not use public urls.
Please check our ASP.NET Core Demo. All of the listed file formats are supported. See Supported file formats for more details.
Client-side is an Angular-based application, the backend is ASP.NET Core. The sources can be also found at GitHub - GroupDocs.Viewer-for-.NET-UI.
Do you have any documentation how we are implement code in angular and core?
Please check the following topic - How to integrate GroupDocs.Viewer in ASP.NET Core Web application.
In case you want to integrate a component into your Angular application you can take a look at the source code of the client app.
It seems that you haven’t started the API service. Sample self-host API can be found on GitHub. Make sure that the API endpoint is set correctly so the front-end can reach a service.
