[Solved] Report engine on the client - WebAssembly

[Daniel]

Hi,

you have this feature "Report engine on the client - WebAssembly" on roadmap for some time already. Is this feature ever going to land? Should we look elsewhere?

Such a roadmap is not very helpful if there is no indication where what is the time frame.

We have large amount of reports implemented using Telerik Reporting. We'd love to avoid migrating to DevExpress or some other tool which has this feature implemented.

Thanks for clarification or pointing me to the right direction. (Blazor WASM with offline report generation).

Best regards,
Daniel

Hello Daniel,

Thank you for the provided information about your scenario!

Indeed, this is a feature that is part of our future, but not immediate plans, I am afraid. On the roadmap page, we share what features we have discussed and intend to work on in the future, some being already implemented, but concrete dates are not listed intentionally.

The priority of the items on the roadmap depends on various factors, such as user interest. If you are interested in seeing this feature being developed, please open a request on our public portal - Progress® Telerik® Reporting Feedback Portal, so that other users who would also want to use it can show their interest by voting for the feature.

Back to the topic of offline report generation (no server, no network), it is currently not possible because the Reporting engine is only server-side. However, there are alternatives that may produce the same result. For example:

• "Offline UI, Online generation" — cache the app shell offline (PWA), but report generation requires a connection to a local or remote API
• Use a local desktop/Electron-style host — run the app in a native wrapper (e.g., .NET MAUI Hybrid or Electron with a local ASP.NET Core server) where the ReportProcessor can run in a real .NET process
• Pre-generate reports — generate and cache report output (PDFs) while online, serve them offline from the PWA cache

I hope that one of the alternative suggestions will work for your needs. Let me know if you have any additional question on either approach.

Dimitar
