# `transportation.trafiklab.departureBoard`

Fetches a public transport departure board from
[Resrobot](https://www.trafiklab.se/api/trafiklab-apis/resrobot-v2-1/) (Trafiklab), for the timestamp
the screen is being rendered at.

```yaml
sources:
  bus:
    source: transportation.trafiklab.departureBoard
    params:
      stopId: "740000001"
      direction: "740000002"
      passlist: 0
      accessId: <your Trafiklab API key>
```

## Params

```{eval-rst}
.. autopydantic_model:: todays_paper_web.widgets.transportation.trafiklab.DepartureBoardParams
```

The request's `date`/`time` parameters come from the source's own `timestamp` — the render time set by
the `Runner` (or by the CLI's `-t` flag, see {doc}`../screen-design/index`), not from `datetime.now()` —
so a departure board renders "as of" whenever the screen it's on was rendered, consistent with the rest
of that render.

## Returns

A list of departure dicts as returned by Resrobot's `Departure` array, with each departure's `time` (and
any `Stops.Stop[].arrTime`) parsed into `datetime`s.

```xml+jinja
{% for departure in source("bus") %}
    <text>{{ departure.time.strftime('%H:%M') }} {{ departure.get('name') }}</text>
{% endfor %}
```
