WebAssembly

Use trunk serve --release to build and host the WebAssembly flowgraph. See the ZigBee example.

Web UI

FutureSDR’s reusable web UI components are implemented in the prophecy crate that is part of the FutureSDR repository. The default Prophecy GUI is served by the control port when a FutureSDR application is running, usually at http://127.0.0.1:1337/.

Prophecy is built with Leptos, a Rust web framework for reactive user interfaces. It is intended both as a small default UI and as a component library for application-specific control panels.

The crate provides:

• RuntimeHandle and FlowgraphHandle: client-side handles for talking to the FutureSDR control-port API from the browser.
• FlowgraphCanvas: graphical flowgraph view with blocks, stream edges, message edges, and clickable message inputs.
• FlowgraphTable: table view of block IDs, instance names, stream ports, message ports, and blocking state.
• Pmt, PmtInput, PmtInputList, and PmtEditor: components for displaying, entering, and submitting PMT values.
• RadioSelector, ListSelector, and Slider: simple controls that post PMT values to a block message handler.
• TimeSink: WebGL time-domain display that reads samples from a websocket or a Leptos signal.
• Waterfall: WebGL waterfall display for streaming spectral data.
• ConstellationSink and ConstellationSinkDensity: WebGL constellation displays for complex sample streams.
• ArrayView: helper trait for exposing Rust numeric slices as JavaScript typed-array views for WebGL uploads.

For a custom web GUI that uses Prophecy components in an application-specific layout, see the WLAN example.
