# `tripsByName([lineNameOrFahrtNr], [opt])`

Get all trips matching one or more criteria, e.g. a specific name.

## Response

As an example, we're going to use the [VBB profile](../p/vbb):

```js
import {createClient} from 'hafas-client'
import {profile as vbbProfile} from 'hafas-client/p/vbb/index.js'

const userAgent = 'link-to-your-project-or-email' // adapt this to your project!
const client = createClient(vbbProfile, userAgent)

const {
	trips,
	realtimeDataUpdatedAt,
} = await client.tripsByName('S1')
```

With `opt`, you can override the default options, which look like this:

```js
{
	// use either this
	when: null,
	// or these
	fromWhen: null, untilWhen: null,

	onlyCurrentlyRunning: true,
	products: {
		// these entries may vary from profile to profile
		suburban: true,
		subway: true,
		tram: true,
		bus: true,
		ferry: true,
		express: true,
		regional: true,
	},

	currentlyStoppingAt: null, // only show trips currently stopping at a stop/station, string
	lineName: null, // only show trips with this line name, string
	operatorNames: null, // only show trips with these operator names, array of strings
}
```

`realtimeDataUpdatedAt` is a UNIX timestamp reflecting the latest moment when (at least some of) the response's realtime data have been updated.

`trips` may look like this:

```js
[
	{
		id: '1|1214|0|86|16092020'
		direction: null,
		line: {
			type: 'line',
