epresso dev

Starts a Starlette dev server with WebSocket live reload. It shares the production incremental engine, so content/template edits are picked up automatically. Use --host / --port / --env.

#Build

epresso build

Produces a deterministic, incremental build into dist/. --clean forces a full rebuild; --env <name> selects a per-environment config.

#Deterministic + incremental

Builds are deterministic (same input → same output) and incremental (edits re-render only affected pages) — see [Incremental builds & caching](../guides/build/incremental.md.
