Standalone Applications

Not every program that wants your modules wants an HTTP server: a CLI command, a queue worker, a one-off data migration. create_application_context() builds the module graph and runs the lifecycle hooks without FastAPI:

import asyncio
 
from austial import AustialFactory
 
from src.app.app_module import AppModule
from src.app.modules.reports.reports_service import ReportsService
 
 
async def main() -> None:
    ctx = await AustialFactory.create_application_context(AppModule)
    try:
        await ctx.get(ReportsService).run_nightly()
    finally:
        await ctx.close()
 
 
asyncio.run(main())

The returned AustialApplicationContext has:

Member	Does
`get(token)`	Resolves a provider (the same as `app.get`).
`resolve(token, context_id=None)`	Resolves a provider of any scope, including request-scoped.
`init()`	Runs the initialization hooks. Already done by `create_application_context()`; idempotent.
`close(signal=None)`	Runs the termination hooks.
`enable_shutdown_hooks(*signals)`	Closes the context on `SIGTERM` / `SIGINT` (or the signals you name).

AustialApplication, what AustialFactory.create() returns, extends this class, so everything above also works on a web application.
