Host backends¶

Two different “backend” concepts appear in docs — do not mix them.

Full contract: Host contract — backends, GridViewHost, HTTP routes (MCP: gridview_catalog → host_backends, host_protocol, http_routes).

Render backends (HTTP / framework)¶

Backend	Install	Render entry	Prefs	Export HTTP
Django	`grid-view-spec` + `INSTALLED_APPS`	`{% render_grid_view_spec %}`	ORM `GridPreference` + optional default `urls.py`	Host-mounted `export_*` + registry
Jinja2	`grid-view-spec` core	`render_html(spec, rows, host=…)`	Host `GridViewHost`	Host
Starlette / FastAPI	`[starlette]` / `[fastapi]`	`page_route()` / `mount_page()`	`InMemoryHost` (in-process); no default POST	Host
Wire / MCP	`[mcp]`	`spec_to_wire`, `gridview_validate`	N/A	N/A

Django is one integration path. The spec contract is framework-agnostic.

Value	Meaning
`simple`	Server-rendered HTML `<table>`; client sort/search/filters
`ag_grid`	AG Grid Community + optional infinite datasource
