Beginner

Install Nextcloud, AppAPI, and the ExApp daemon. Understand the Docker-based deployment model and how an ExApp registers with Nextcloud. First occ app_api:app:register cycle.

The ExApp manifest, registration with AppAPI, nc_py_api basics. How Nextcloud calls your service — the signing protocol, what headers arrive, and what you must verify before trusting a request. The ExApp lifecycle vs a PHP app lifecycle.

Request handlers with FastAPI, nc_py_api for calling Nextcloud APIs, and returning JSON responses from your first Pinboard endpoints. How requests reach your Python service and how to return typed responses — the ExApp equivalent of PHP controllers.

Nextcloud's KV store via nc_py_api for lightweight config, your own SQLite/Postgres sidecar for structured pin data, and when to use each. Define the pins table, write basic CRUD, scope all queries to the current user.

Set up Vite and Vue for an ExApp — serving static assets from the Python service, wiring the registered top-level entry to a Vue entry point. The ExApp frontend model differs from PHP apps: assets are served by your service, not by Nextcloud.

Build the Pinboard UI in three stages — fetch and display pins, add loading and empty states, then wire up a form to create new ones. @nextcloud/axios for CSRF-safe calls back to your own Python API. Same @nextcloud/vue components as the PHP track.

Verifying the current user via AppAPI — what identity claims arrive in the request, what you can trust, and what you must verify. Scoping all pin queries to the current user. The difference between nc_py_api user context and a PHP IUserSession.

Building the Docker image, the ExApp store manifest, signing, and registering your app on the Nextcloud app store. The differences from PHP app packaging — Docker image vs signed zip, AppAPI registration vs plain app enable.
