Phoenix LiveView + Ecto + PostgreSQL Starter

Phoenix LiveView, PostgreSQL, Ecto SQL, LiveView Streams, and ExUnit form a server rendered app configuration where one server framework renders the browser UI and owns the backend. Better Fullstack can scaffold this exact compatibility-checked selection.

Compatibility notes

Compatibility checked against Better Fullstack types version 2.8.0.

The generated record has 0 graph issues and 0 disabled selected options. This is a compatibility check, not a claim that this exact scaffold received a runtime smoke verification.

  • Elixir Auth is intentionally set to none.
  • Elixir API Layer is intentionally set to none.
  • Elixir Jobs is intentionally set to none.

When to choose this shape

Choose this shape when one server framework should render the browser UI without a separate frontend app.

Questions

Is this combination supported?

It passes the repository's compatibility analysis, selected-option checks, stack graph validation, project schema parsing, and virtual generation. That result is described here as compatibility checked.

Does it generate one app or separate parts?

One server framework renders the browser UI and owns the backend. The actual generated output uses a single-directory layout.

How can I customize the selection?

Open the generated builder link above. Its query parameters reproduce this selection, and the builder can change compatible options before generating a new command.
