# 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, seeds a local PocketBase superuser, and mounts `pb/pb_migrations` so a fresh volume is auto-seeded (see below). |
| `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, and removes the seed mount so the dev seed does not run during tests. |
> **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.
The fixture creates the collections by importing the **same** schema file the dev
seed uses (see the next section), so the schema is defined once. Its *records*,
though, are fixed in `PocketBaseFixture` on purpose — the tests assert against
values that file controls (a non-public draft page that must never show, an event
at a known time), not against the dev seed's content. The test overlay therefore
drops the `pb_migrations` mount so the dev seed does **not** run during tests.
**Requirements:** Docker with the Compose plugin must be available when the tests
run (they call `docker compose`).
---
## Example content on a fresh volume (the dev seed)
A fresh dev volume comes up populated, so a first `docker compose … up` shows a
working site instead of an empty one. Two files under `pb/pb_migrations/` do this,
and the dev overlay mounts that folder into PocketBase (`./pb/pb_migrations:/pb_migrations`):
| File | Role |
|---|---|
| `collections_schema.json` | The five content collections (`pages`, `posts`, `events`, `faq_topics`, `faqs`) as PocketBase exports them. **The single source of truth for the schema** — the test fixture imports this same file. |
| `<timestamp>_dev_seed.js` | The PocketBase migration. Reads the schema file, creates any missing collection, then inserts the example records. |
Both steps are **idempotent**: a collection is created only if it is missing, and
filled only while it is empty. So a populated volume — or the production DB, should
this ever run there — is never touched. To start over from an empty, then freshly
seeded volume:
```bash
docker volume rm eb-stack_pb_data_dev
docker compose -f compose.yaml -f compose.dev.yaml up --build
```
> **Seed only in dev.** The `pb_migrations` mount lives in `compose.dev.yaml`
> alone. The base (production) file does not mount it, and the test overlay
> removes it again — production content is seeded by hand, never from this repo.
### Refreshing the seed after a schema or content change
The seed is generated from a running dev instance, not hand-edited. When you
change a collection's schema in the admin UI, or want to capture the current
example content as the new seed, re-export from the running dev PocketBase
(authenticated as the dev superuser) and regenerate the two files. The schema file
is the plain export of the four collections; the migration embeds the records the
same way. After regenerating, prove it end to end:
```bash
docker volume rm eb-stack_pb_data_dev # force a fresh volume
docker compose -f compose.yaml -f compose.dev.yaml up --build
dotnet test # fixture imports the new schema
```
---
## 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`.
---
## Adding a new content type
Editors can add **records** to the existing collections and add plain text
`pages`, but a **new kind of list** — its own collection rendered on its own
route with its own sorting or grouping — is a development task, not editorial.
It takes three steps, all small because the plumbing is shared:
1. **Collection + DTO.** Create the collection in the PocketBase admin (give it a
`public` bool and open List/View rules, like the others), then add a matching
record type in `Elternbeirat.Contracts` with `[JsonPropertyName(...)]` on each
field — mirror `Page`/`Post`.
2. **Client method.** Add one method to `PocketBaseClient`. The shared
`GetRecordsAsync<T>(collection, sort, ct)` already does the `public=true`
filter, the sort and the deserialization, so a new type is a one-liner:
`public Task<IReadOnlyList<Minutes>> GetMinutesAsync(CancellationToken ct = default)`
`=> GetRecordsAsync<Minutes>("minutes", "-date", ct);`
3. **Feature component.** Add a component under `Features/<Name>/` with its own
`@page "/…"` route that injects `PocketBaseClient`, calls the new method and
renders the result. Literal routes win over the `/{Slug}` catch-all, so pick a
slug that no `pages` record needs. Follow an existing list (`PostList`,
`EventList`, `FaqList`) for the load-in-`OnInitializedAsync`, log-and-degrade
pattern, and add a route smoke test plus a fixture seed.
Also refresh the seed so the new collection comes up on a fresh volume and in the
tests: re-export it into `pb/pb_migrations/collections_schema.json` (the shared
schema) and add example rows to the dev seed migration — see *Refreshing the seed*
above. The test fixture picks the new schema up automatically once it is in the
file.
Text pages need none of this — they are all served generically by
`ContentPage` (`@page "/{Slug}"`), which is why a new `pages` record is live
without a rebuild.
