# Local development
How to run the site on your own machine and how the tests run. The app is one
container (`eb-blazor`) that reads its content from a second container running
PocketBase (`eb-pocketbase`); both come up together as a compose stack.
For deploying a built image to Unraid, see `deployment.md`. For the architecture
reasoning, see `architektur.md`.
---
## The three compose files
There is one stack, described by a base file plus two overlays. You never edit
the base for a local run — you layer an overlay on top of it.
| File | Role |
|---|---|
| `compose.yaml` | Base, production-shaped: both services, **no** host ports, PocketBase data on the Unraid bind mount. Also holds the fixed project name `eb-stack`. |
| `compose.dev.yaml` | Dev overlay: adds host ports (5000, 8090), builds the web image from local source instead of pulling it, swaps the Unraid bind mount for a throwaway volume, and seeds a local PocketBase superuser. |
| `compose.test.yaml` | Test overlay: used **only** by the integration tests. Drops the fixed host port and container names so a test run does not collide with a running dev stack. |
> **Project name.** `name: eb-stack` is set once, in the base. The overlays
> deliberately don't set their own `name:` — a competing `name:` across `-f`
> files resolves depending on load order (and the CLI and Rider load them in
> opposite orders), so keeping it in one place avoids surprises. The tests
> override it with `-p eb-test-stack`.

## Running the dev stack
### From Rider (one click)
The run configuration **DevEnvironment** (`.run/DevEnvironment.run.xml`, checked
in) starts the stack with `--build` and force-recreate. It loads the dev overlay
on top of the base for you — just press run.
### From the terminal
```bash
docker compose -f compose.yaml -f compose.dev.yaml up --build
```
PocketBase starts first; once its healthcheck passes, the web app starts
(`depends_on: service_healthy`). Then:
- Web app: <http://localhost:5000>
- PocketBase admin UI: <http://localhost:8090/_/>
- PocketBase health: <http://localhost:8090/api/health>
> The dev overlay auto-creates a PocketBase superuser (`test@example.com` /
> `test-password`) on a **fresh** volume, so you skip the `/_/` setup screen.
> These are throwaway local credentials, not the production ones.
Stop and clean up (removes the throwaway PocketBase volume too):
```bash
docker compose -f compose.yaml -f compose.dev.yaml down --volumes
```
If the admin UI already existed once and you want the superuser recreated from
scratch, remove the volume first: `docker volume rm eb-stack_pb_data_dev`.
---
## Running the tests
```bash
dotnet test
```
The integration tests (`PocketBaseFixture` in `Elternbeirat.Web.Tests`) start
their **own** PocketBase from the very same compose files — the fixture shells
out to:
```bash
docker compose -p eb-test-stack -f compose.yaml -f compose.dev.yaml -f compose.test.yaml up --detach --wait eb-pocketbase
```
so the image version, environment and port are defined in one place, not
duplicated in the test code. Only `eb-pocketbase` is started; the web app is not
built for the tests.
Because the test stack has its own project name (`eb-test-stack`), auto-named
containers and a **random** host port, it runs happily **alongside** a running
dev stack — you can have DevEnvironment up in Rider and run `dotnet test` at the
same time. The fixture cleans up before and after each run, so a hard-killed
earlier run leaves nothing behind.
**Requirements:** Docker with the Compose plugin must be available when the tests
run (they call `docker compose`).

## Content while developing
The app reads its content from PocketBase over the compose network
(`PocketBase__BaseUrl=http://eb-pocketbase:8090` — the *service* name, resolved
inside the compose network, independent of the container name). Editing content
means editing records in the PocketBase admin UI at
<http://localhost:8090/_/>, not editing files. See `redaktion.md`.
