Analytics graphs
A small Rust web server that logs in through AuthService.Login, forwards SQL
queries to AnalyticsService.ExecuteAnalyticsQuery, and displays the streamed
result with HTMX, Alpine.js, and ECharts.
Run
The web UI is a library started by the main server; it is no longer a standalone binary. From the parent workspace, start the server normally:
cargo run -p server -- server
Open http://127.0.0.1:3000/login to log in, then use the analytics page at
http://127.0.0.1:3000. The access token is kept in an HTTP-only cookie. The default gRPC endpoint is
http://[::1]:50051. Both addresses can be changed:
ANALYTICS_GRPC_ENDPOINT=http://127.0.0.1:50051 \
LISTEN_ADDRESS=127.0.0.1:8080 \
cargo run -p server -- server
The first SQL result column is used for category labels. Bar and line charts use all remaining columns as numeric series, pie uses the second column, and scatter uses the first two columns. Table view displays every returned value.
The profile selector is populated automatically through
TableDefinition.GetProfileTree. Choosing a profile fetches its live public
analytics catalog. The sidebar shows tables, columns, types, and links and can
create starter queries. Its LLM schema context section generates a complete
text summary that can be copied into an LLM prompt to request a valid analytics
SQL query.
HTMX, Alpine.js, and ECharts are loaded from jsDelivr, so the browser needs network access when opening the page. HTMX owns server communication and fragment swaps; Alpine is limited to browser-local editor, clipboard, and chart behavior.
