bazaar-contrib-server

The Bazaar Compute server itself. The server entry draws the shell around every module — the sidebar, the overview and the settings page — and offers SERVER, where modules register their pages, API and permission points, and THEME, where theme contribs register the looks the pages can wear. The server-theme-night and server-theme-day entries are the theme plugins it comes with: the night market and the morning market.

[[contribs]]
package = "bazaar-contrib-server~=0.3.0rc1"
[[contribs.enabled]]
entry = "server"
[[contribs.enabled]]
entry = "server-theme-night"
[[contribs.enabled]]
entry = "server-theme-day"

A module registers what it serves inside its lifespan; each registration holds while its context is open:

import asyncio
from contextlib import asynccontextmanager

from bazaar_contrib_server import SERVER, PermissionItem, SidebarItem
from bazaar_core import Context, Contrib
from importlib.resources import files
from pathlib import Path
from starlette.routing import Route


@asynccontextmanager
async def lifespan(ctx: Context):
    server = ctx.accept(SERVER)
    pages = await server.pages("notes", __package__)

    async def home(request):
        return await pages.render(request, "notes.html")

    resources = Path(str(files(__package__))) / "resources"
    icon = await asyncio.to_thread((resources / "notes.svg").read_text)
    async with (
        server.module(
            "notes",
            ui=pages.application([Route("/", home)]),
            static=resources / "static",
            locales=resources / "locales",
        ),
        server.permission(
            PermissionItem(point="notes.view", description="notes.view.description")
        ),
        server.sidebar(
            SidebarItem(
                text="notes.title",
                icon=icon,
                path="/notes",
                permission="notes.view",
            )
        ),
    ):
        yield


notes = Contrib(accepts=[SERVER], lifespan=lifespan)

The icon is an SVG drawn as the design's are, with class i and a 24×24 view box. The module's interface is served at /ui/notes inside the shell at /notes, its API at /api/notes and its files at /static/notes. Its templates live in resources/templates of its package and extend server/base.html, which brings the theme stylesheet and the embedding script; pages of any other framework include /static/server/theme.css and /static/server/embed.js themselves. Everything behind the shell needs a login module, which registers itself with server.login; until one does, those pages and APIs answer 503.
