An Axum SSR/HTMX web frontend for the existing komp_ac gRPC backend. It provides the browser version of the client admin panel and the ECharts analytics view. The browser never connects to gRPC directly: Axum authenticates with an HTTP-only cookie, creates typed Tonic requests, and returns full HTML pages or HTMX fragments.

The backend remains the authority; this crate does not add another HTTP API to it.

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. The admin panel is at http://127.0.0.1:3000/admin and analytics remains 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

Admin panel

The admin panel mirrors the client workflow with browser-oriented pages:

profile, table, and physical-column browsing;
table creation, including indexes, links, money settings, and row labels;
Steel table-script creation;
field validations, reusable global rules, validation sets, and set application;
browser CSV import with live schema validation and chunked bulk insertion;
CSV downloads for one or multiple tables;
login, role checks, logout, and navigation to analytics.

CSV files use the same column-header convention as the client. Multi-table CSV files include a table-name header row before the column-name row. Browser files are read locally and submitted to Axum; the backend is accessed only through the existing TablesData gRPC service.

Analytics

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.
