# Profiles
# `hafas-client` profiles
This directory contains specific customisations for each endpoint, called *profiles*. They **parse data from the API differently, add additional information, or enable non-default methods** (such as [`trip`](../docs/trip.md)) if they are supported.
This directory contains specific customisations for each endpoint, called *profiles*. They **parse data from the API differently, add additional information, or add special methods specific to the endpoint** (such as [`journeysFromTrip`](https://github.com/public-transport/hafas-client/blob/453f4b0e1005ecb85569e1bd08096ed4c77f4184/docs/journeys-from-trip.md)).
Each profile has it's own directory. It will be passed into `hafas-client` and is expected to be in a certain structure:

## writing your own
If you want to write a profile for an endpoint, check out the [*writing a profile* guide](../docs/writing-a-profile.md).
Your profile must be passed into `createClient` and is expected to be in a certain structure:
```js
const createClient = require('hafas-client')
const someProfile = require('hafas-client/p/some-profile')
const myCustomProfile = {
// …
}
// create a client with the profile
const client = createClient(dbProfile)
const client = createClient(myCustomProfile)
// use it to query data…
// use it to query data
await client.journeys('1234', '2345')
```
If you want to write a profile for an endpoint, check out the [*writing a profile* guide](../docs/writing-a-profile.md).

## Background
[A company called HaCon](https://hacon.de) sells [a public transport management system called HAFAS](https://de.wikipedia.org/wiki/HAFAS). It is [used by public transport providers across Europe](https://gist.github.com/derhuerst/2b7ed83bfa5f115125a5) to provide routing and departure information to their customers.
[A company called HaCon](https://hacon.de) sells [a public transport management system called HAFAS](https://de.wikipedia.org/wiki/HAFAS) to public transport authorities and providers, mostly in Europe. It provides routing and departure information to their customers.
Most customers get their own, **separate HAFAS deployments**; They all use the same terminology and API calls, but have slightly different versions, configurations and sets of enabled features. Using [endpoint-specific customisations that we call *profiles*](p), **`hafas-client` abstracts most of these differences away, and supports additional features in some cases**. Check the [*supported networks/endpoints* list](#supported-networksendpoints) for more info.
Most customers get their own, **separate HAFAS deployments**; They all use the same terminology and API calls, but have slightly different versions, configurations and sets of enabled features.

Check the [list of supported networks/endpoints](p/readme.md#built-in-profiles) for more info.
*Note:* Currently, **`hafas-client` only supports "mobile API" endpoints**, which are designed for and used by the respective official mobile app(s); These endpoints almost always have `mgate.exe` in the URL. This library *does not* support "open API" endpoints (often they have `rest-proxy` or `openapi` in the URL) yet, but [#134](https://github.com/public-transport/hafas-client/pull/134) contains work in progress.
Strictly speaking, permission is necessary to use `hafas-client` with a HAFAS "mobile" endpoint. It merely tries to remove the *technical* barrier of accessing the data, in order to kick-start an ecosystem or apps and services that would eventually rely on [*openly available* data](https://opendatahandbook.org/solutions/en/Public-Transport-Data/).

### in the browser
While `hafas-client` itself should work in the browser via a bundler like [Webpack](https://webpack.js.org), most HAFAS API endpoints don't enable [CORS](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing), so you won't be able query them directly.
