@@ -24,38 +24,103 @@ With `opt`, you can override the default options, which look like this:
 ```js
 {
 	when:      new Date(),
-	direction: null, // only show departures heading to this station
-	duration:  10 // show departures for the next n minutes
+	direction: null, // only supported in `dbweb` and with `enrichStations=true` (experimental)

+	includeRelatedStations: true,
+	moreStops: null // also include departures/arrivals for array of up to nine additional station evaNumbers (not supported with dbnav and dbweb)
+	language: 'en' // language to get results in
 }
 ```
+The maximum supported duration depends on the profile (see main readme), e.g. 720 for `db` and 60 for `dbnav`. In order to use the `dbris` profile, you need to pass the env vars `DB_API_KEY` and `DB_CLIENT_ID`.
+If you pass an object `opt.products`, its fields will partially override the default products defined in the profile.
 
 ## Response
 
-*Note:* As stated in the [*Friendly Public Transport Format* `1.0.1`](https://github.com/public-transport/friendly-public-transport-format/tree/1.0.1), the `when` field includes the current delay. The `delay` field, if present, expresses how much the former differs from the schedule.
+*Note:* As stated in the [*Friendly Public Transport Format* v2 draft spec](https://github.com/public-transport/friendly-public-transport-format/blob/3bd36faa721e85d9f5ca58fb0f38cdbedb87bbca/spec/readme.md), the `when` field includes the current delay. The `delay` field, if present, expresses how much the former differs from the schedule.
 
-You may pass the `journeyId` field into [`journeyLeg(ref, lineName, [opt])`](journey-leg.md) to get details on the vehicle's journey.
+You may pass a departure's `tripId` into [`trip(id, lineName, [opt])`](trip.md) to get details on the whole trip. For the `dbnav`/`dbweb` profile HAFAS trip ids will be returned, for the `db` profile, RIS trip ids will be returned, then the `trip()` endpoint supports both id types.
 
-As an example, we're going to use the [VBB profile](../p/vbb):
+For `db` profile, cancelled trips will not be contained in the response! For the `db` and `dbnav` profile, only the most important remarks will be contained in the boards.
 
 ```js
-const createClient = require('hafas-client')
-const vbbProfile = require('hafas-client/p/vbb')
+import {createClient} from 'db-vendo-client'
+import {profile as dbnavProfile} from 'db-vendo-client/p/dbnav/index.js'

+# Dumps from DB Navigator API app.vendo.noncd.db.de
+
+In this directory, some intercepted traffic from DB Navigator. (Repo license does not apply to this directory.)
+
+You can browse some responses of the bahn.de API and others in the [fixtures](https://github.com/public-transport/db-vendo-client/tree/main/test/fixtures) and [e2e fixtures](https://github.com/public-transport/db-vendo-client/tree/main/test/e2e/fixtures).
+
+How to intercept DB Navigator traffic:
+
+1. Download/extract Split APK
+2. Merge APK (e.g. using [APKEditor](https://github.com/REAndroid/APKEditor))
+3. decompile using apktool
+4. edit [res/xml/network_security_config.xml](https://developer.android.com/privacy-and-security/security-config) to allow user CAs not just in debug 
+5. recompile using apktool, sign
+6. install on an Android
+7. intercept with a mitm decryption tool of your choice by installing CA cert into Android store (e.g. [PCAPdroid](https://github.com/emanuele-f/PCAPdroid) with [mitm addon](https://github.com/emanuele-f/PCAPdroid-mitm), no root needed)

-# `journeyLeg(ref, lineName, [opt])`
-
-This method can be used to refetch information about a leg of a journey. Note that it is not supported by every profile/endpoint.
-
-Let's say you used [`journeys`](journeys.md) and now want to get more up-to-date data about the arrival/departure of a leg. You'd pass in a journey leg `id` like `'1|24983|22|86|18062017'`. `lineName` must be the name of the journey leg's `line.name`. You can get them like this:
-
-```js
-const createClient = require('hafas-client')
-const vbbProfile = require('hafas-client/p/vbb')
-
-const client = createClient(vbbProfile)
-
-// Hauptbahnhof to Heinrich-Heine-Str.
-client.journeys('900000003201', '900000100008', {results: 1})
-.then(([journey]) => {
-	const leg = journey.legs[0]
-	return client.journeyLeg(leg.id, leg.line.name)
-})
-.then(console.log)
-.catch(console.error)
-```
-
-With `opt`, you can override the default options, which look like this:
-
-```js
-{
-	when: new Date(),
-	passedStations: true // return stations on the way?
-}
-```
-
-## Response
-
-*Note:* As stated in the [*Friendly Public Transport Format* `1.0.1`](https://github.com/public-transport/friendly-public-transport-format/tree/1.0.1), the returned `departure` and `arrival` times include the current delay. The `departureDelay`/`arrivalDelay` fields express how much they differ from the schedule.

-Some [profiles](../p) are able to parse the ticket information, if returned by the API. For example, if you pass `tickets: true` with the [VBB profile](../p/vbb), each `journey` will have a tickets array that looks like this:

+## Migrating from an old (v5) `hafas-client` version
+
+`db-vendo-client` tries to be as compatible as possible with `hafas-client` v6. If you were still on v5 or earlier, see the [`5` → `6` migration guide](https://github.com/public-transport/hafas-client/blob/main/docs/migrating-to-6.md) of `hafas-client`.
+
+## Throttling requests
+
+There's opt-in support for throttling requests to the endpoint.
+
+```js
+import {createClient} from 'db-vendo-client'
+import {withThrottling} from 'db-vendo-client/throttle.js'
+import {profile as dbProfile} from 'db-vendo-client/p/db/index.js'
+
+const userAgent = 'link-to-your-project-or-email' // adapt this to your project!
+
+// create a throttled HAFAS client with Deutsche Bahn profile
+const client = createClient(withThrottling(dbProfile), userAgent)
+
+// Berlin Jungfernheide to München Hbf
+await client.journeys('8011167', '8000261', {results: 1})
+```
+
+You can also pass custom values for the nr of requests (`limit`) per interval into `withThrottling`:
+
+```js
+// 2 requests per second
+const throttledDbProfile = withThrottling(dbProfile, 2, 1000)
+const client = createClient(throttledDbProfile, userAgent)
+```
+
+## Retrying failed requests
+
+There's opt-in support for retrying failed requests to the endpoint.
+
+```js
+import {createClient} from 'db-vendo-client'
+import {withRetrying} from 'db-vendo-client/retry.js'
+import {profile as dbProfile} from 'db-vendo-client/p/db/index.js'
+
+const userAgent = 'link-to-your-project-or-email' // adapt this to your project!
+
+// create a client with Deutsche Bahn profile that will retry on HAFAS errors
+const client = createClient(withRetrying(dbProfile), userAgent)
+```
+
+You can pass custom options into `withRetrying`. They will be passed into [`retry`](https://github.com/tim-kos/node-retry#tutorial).
+
+```js
+// retry 2 times, after 10 seconds & 30 seconds
+const retryingDbProfile = withRetrying(dbProfile, {
+	retries: 2,
+	minTimeout: 10 * 1000,
+	factor: 3
+})
+const client = createClient(retryingDbProfile, userAgent)
+```
+
+## User agent randomization
+
+By default, `db-vendo-client` does not randomize the client name that you pass into `createClient`, and sends it as [`User-Agent`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent) as it is. At least DB Navigator always sends the same user agent as well (cf. `dbnav` profile).  You can turn on randomization by setting `profile.randomizeUserAgent` to `false`:
+
+```js
+const client = createClient({
+	...someProfile,
+	randomizeUserAgent: true,
+}, userAgent)
+```
+
+## Logging requests
+
+You can use `profile.logRequest` and `profile.logResponse` to process the raw [Fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) [`Request`](https://developer.mozilla.org/en-US/docs/Web/API/Request) and [`Response`](https://developer.mozilla.org/en-US/docs/Web/API/Response), respectively.
+
+As an example, we can implement a custom logger:
+
+```js
+import {createClient} from 'db-vendo-client'
+import {profile as dbProfile} from 'db-vendo-client/p/db/index.js'
+
+const userAgent = 'link-to-your-project-or-email' // adapt this to your project!
+
+const logRequest = (ctx, fetchRequest, requestId) => {
+	// ctx looks just like with the other profile.* hooks:
+	const {dbProfile, opt} = ctx
+
+	console.debug(requestId, fetchRequest.headers, fetchRequest.body + '')
+}
+
+const logResponse = (ctx, fetchResponse, body, requestId) => {
+	console.debug(requestId, fetchResponse.headers, body + '')
+}
+
+// create a client with Deutsche Bahn profile that debug-logs
+const client = createClient({
+	...dbProfile,
+	logRequest,
+	logResponse,
+}, userAgent)
+```
+
+```js
+// logRequest output:
+'29d0e3' {
+	accept: 'application/json',
+	'accept-encoding': 'gzip, br, deflate',
+	'content-type': 'application/json',
+	connection: 'keep-alive',
+	'user-agent': 'hafas842c51-clie842c51nt debug C842c51LI'
+} {"lang":"de","svcReqL":[{"cfg":{"polyEnc":"GPA"},"meth":"LocMatch",…
+// logResponse output:
+'29d0e3' {
+	'content-encoding': 'gzip',
+	'content-length': '1010',
+	'content-type': 'application/json; charset=utf-8',
+	date: 'Thu, 06 Oct 2022 12:31:09 GMT',
+	server: 'Apache',
+	vary: 'User-Agent'
+} {"ver":"1.45","lang":"deu","id":"sb42zgck4mxtxm4s","err":"OK","graph"…
+```
+
+The default `profile.logRequest` [`console.error`](https://nodejs.org/docs/latest-v10.x/api/console.html#console_console_error_data_args)s the request body, if you have set `$DEBUG` to `hafas-client`. Likewise, `profile.logResponse` `console.error`s the response body.
+
+## Error handling
+
+Unexpected errors – e.g. due to bugs in `db-vendo-client` itself – aside, its methods may reject with the following errors:
+
+- `Error` – A generic error, e.g. if the DB backend returned a HTTP error.
+- `HafasError` – A generic error to signal that something HAFAS-related went wrong, either in the client, or in the HAFAS endpoint.
+
+Each `HafasError` error has the following properties:
+
+- `isHafasError` – Always `true`. Allows you to distinguish HAFAS-related errors from e.g. network errors.

+## Using `db-vendo-client` from another language
+
+If you want to use `db-vendo-client` to access DB APIs but work with non-Node.js environments, you can use it together with [hafas-rest-api](https://github.com/public-transport/hafas-rest-api) to create a REST API (see the [root readme](https://github.com/public-transport/db-vendo-client/tree/main#usage) and the Docker image). 
+Or use [`hafas-client-rpc`](https://github.com/derhuerst/hafas-client-rpc) to create a [JSON-RPC](https://www.jsonrpc.org) interface that you can send commands to.

+# automated tests in `db-vendo-client`
+
+Because transit data is inherently dynamic (e.g. a different set of departures being returned for a stop now than in 10 minutes), and because it is of paramount importance that `db-vendo-client` actually works with HAFAS endpoints *as they currently work*, its testing setup is a bit unusual.
+
+`db-vendo-client` has three kinds of automated tests:
+- unit tests, which test individual aspects of the case base in isolation (e.g. the parsing of HAFAS-formatted dates & times) – run via `npm run test-unit`
+- end-to-end (E2E) tests, which run actual HTTP requests against their respective profile's HAFAS endpoint – run via `npm run test-e2e`
+- integration tests, which are the E2E tests running against pre-recorded (and checked-in) HTTP request fixtures – run via `npm run test-integration`
+
+Because the E2E & integration tests are based on the same code, when changing this code, you should also update the integration test fixtures accordingly.
+
+*Note:* In order to be as reproducible as possible, the tests query transit data for a certain *fixed* point in time on the future, hard-coded in each profile's test suite (a.k.a. each file `test/e2e/*.js`). In combination with the recording & mocking of HTTP requests, this effectively makes the integration tests deterministic.
+
+## adding integration test fixtures
+
+As an example, let's assume that we have added an entirely new test to [the *DB* profile's E2E tests](../test/e2e/db.js).
+
+The behaviour of the HTTP request recording (into fixtures) and mocking (using the recorded fixtures) is controlled via an environment variable `$VCR_MODE`:
+- By running the test(s) with `VCR_MODE=record`, we can record the HTTP requests being made. The tests will run just like without `$VCR_MODE`, except that they will query data for date+time specified in `T_MOCK` (e.g. [here](https://github.com/public-transport/db-vendo-client/blob/8ff945c07515155380de0acb33584e474d6d547c/test/e2e/db.js#L33)).
+- Then, by running the test(s) with `VCR_MODE=playback`, because their HTTP requests match the pre-recorded fixtures, they work on the corresponding mocked HTTP responses.
+
+Usually, you would not want to update all *already existing* recorded HTTP request fixtures of the test suite you have made changes in, as they are unrelated to the test you have added. To only record your *added* test, temporarily change `tap.test(…)` to read `tap.only(…)`, and run with `TAP_ONLY=1 VCR_MODE=record`; This will skip all unrelated tests entirely.
+
+Then, check the augmented fixtures (in `test/e2e/fixtures`) into Git, and revert the `tap.only(…)` change. To make sure that everything works, run the entire test suite/file (*without `TAP_ONLY=1`*) with `VCR_MODE=playback`.
+
+*Note:* It might be that the test suite/file you want to augment hasn't been updated in a while, so that `T_MOCK` is in the past. In this case, recording additional fixtures from actual HTTP requests of your added test is usually not possible because the HAFAS API is unable to serve old transit data. In this case, you will first have to change `T_MOCK` to a future date+time (a weekday as "normal" as possible) and re-record all tests' HTTP requests; Don't hesitate to get in touch with me if you have trouble with this.

-# Writing a profile
-
-**Per endpoint, `hafas-client` has an endpoint-specific customisation called *profile*** which may for example do the following:
-
-- handle the additional requirements of the endpoint (e.g. authentication),
-- extract additional information from the data provided by the endpoint,
-- guard against triggering bugs of certain endpoints (e.g. time limits).
-
-This guide is about writing such a profile. If you just want to use an already supported endpoint, refer to the [API documentation](readme.md) instead.
-
-*Note*: **If you get stuck, ask for help by [creating an issue](https://github.com/derhuerst/hafas-client/issues/new)!** We want to help people expand the scope of this library.
-
-## 0. How do the profiles work?
-
-A profile contains of three things:
-
-- **mandatory details about the HAFAS endpoint**
-	- `endpoint`: The protocol, host and path of the endpoint.
-	- `locale`: The [BCP 47](https://en.wikipedia.org/wiki/IETF_language_tag) [locale](https://en.wikipedia.org/wiki/Locale_(computer_software)) of your endpoint (or the area that your endpoint covers).
-	- `timezone`: An [IANA-time-zone](https://www.iana.org/time-zones)-compatible [timezone](https://en.wikipedia.org/wiki/Time_zone) of your endpoint.
-- **flags indicating that features are supported by the endpoint** – e.g. `journeyRef`
-- **methods overriding the [default profile](../lib/default-profile.js)**
-
-As an example, let's say we have an [Austrian](https://en.wikipedia.org/wiki/Austria) endpoint:
-
-```js
-const myProfile = {
-	endpoint: 'https://example.org/bin/mgate.exe',
-	locale: 'de-AT',
-	timezone: 'Europe/Vienna'
-}
-```
-
-Assuming the endpoint returns all lines names prefixed with `foo `, We can strip them like this:
-
-```js
-// get the default line parser
-const createParseLine = require('hafas-client/parse/line')
-
-const createParseLineWithoutFoo = (profile, operators) => {
-	const parseLine = createParseLine(profile, operators)
-
-	// wrapper function with additional logic
-	const parseLineWithoutFoo = (l) => {
-		const line = parseLine(l)
-		line.name = line.name.replace(/foo /g, '')
-		return line
-	}
-	return parseLineWithoutFoo
-}
-
-profile.parseLine = createParseLineWithoutFoo
-```
-
-If you pass this profile into `hafas-client`, the `parseLine` method will override [the default one](../parse/line.js).
-
-## 1. Setup
-
-*Note*: There are many ways to find the required values. This way is rather easy and has worked for most of the apps that we've looked at so far.
-
-1. **Get an iOS or Android device and download the "official" app** for the public transport provider that you want to build a profile for.
-2. **Configure a [man-in-the-middle HTTP proxy](https://docs.mitmproxy.org/stable/concepts-howmitmproxyworks/)** like [mitmproxy](https://mitmproxy.org).
-	- Configure your device to trust the self-signed SSL certificate, [as outlined in the mitmproxy docs](https://docs.mitmproxy.org/stable/concepts-certificates/).
-	- *Note*: This method does not work if the app uses [public key pinning](https://en.wikipedia.org/wiki/HTTP_Public_Key_Pinning). In this case (the app won't be able to query data), please [create an issue](https://github.com/derhuerst/hafas-client/issues/new), so we can discuss other techniques.
-3. **Record requests of the app.**
-	- [There's a video showing this step](https://stuff.jannisr.de/how-to-record-hafas-requests.mp4).
-	- Make sure to cover all relevant sections of the app, e.g. "journeys", "departures", "live map". Better record more than less; You will regret not having enough information later on.
-	- To help others in the future, post the requests (in their entirety!) on GitHub, e.g. in as format like [this](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886). This will also let us help you if you have any questions.
-
-## 2. Basic profile
-
-- **Identify the `endpoint`.** The protocol, host and path of the endpoint, *but not* the query string.
-	- *Note*: **`hafas-client` for now only supports the interface providing JSON** (generated from XML), which is being used by the corresponding iOS/Android apps. It supports neither the JSONP, nor the XML, nor the HTML interface. If the endpoint does not end in `mgate.exe`, it mostly likely won't work.
-- **Identify the `locale`.** Basically guess work; Use the date & time formats as an indicator.
-- **Identify the `timezone`.** This may be tricky, a for example [Deutsche Bahn](https://en.wikipedia.org/wiki/Deutsche_Bahn) returns departures for Moscow as `+01:00` instead of `+03:00`.
-- **Copy the authentication** and other meta fields, namely `ver`, `ext`, `client` and `lang`.
-	- You can find these fields in the root of each request JSON. Check [a VBB request](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886#file-1-http-L13-L22) and [the corresponding VBB profile](https://github.com/derhuerst/hafas-client/blob/6e61097687a37b60d53e767f2711466b80c5142c/p/vbb/index.js#L22-L29) for an example.
-	- Add a function `transformReqBody(body)` to your profile, which assigns them to `body`.
-	- Some profiles have a `checksum` parameter (like [here](https://gist.github.com/derhuerst/2a735268bd82a0a6779633f15dceba33#file-journey-details-1-http-L1)) or two `mic` & `mac` parameters (like [here](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886#file-1-http-L1)). If you see one of them in your requests, jump to [*Appendix A: checksum, mic, mac*](#appendix-a-checksum-mic-mac). Unfortunately, this is necessary to get the profile working.
-
-## 3. Products
-
-In `hafas-client`, there's a difference between the `mode` and the `product` field:
-
-- The `mode` field describes the mode of transport in general. [Standardised by the *Friendly Public Transport Format* `1.0.1`](https://github.com/public-transport/friendly-public-transport-format/blob/1.0.1/spec/readme.md#modes), it is on purpose limited to a very small number of possible values, e.g. `train` or `bus`.
-- The value for `product` relates to how a means of transport "works" *in local context*. Example: Even though [*S-Bahn*](https://en.wikipedia.org/wiki/Berlin_S-Bahn) and [*U-Bahn*](https://en.wikipedia.org/wiki/Berlin_U-Bahn) in Berlin are both `train`s, they have different operators, service patterns, stations and look different. Therefore, they are two distinct `product`s `subway` and `suburban`.
-
-**Specify `product`s that appear in the app** you recorded requests of. For a fictional transit network, this may look like this:
-
-```js
-const products = {
-	commuterTrain: {
-		product: 'commuterTrain',
-		mode: 'train',
-		bitmask: 1,
-		name: 'ACME Commuter Rail',
-		short: 'CR'
-	},
-	metro: {
-		product: 'metro',
-		mode: 'train',
-		bitmask: 2,
-		name: 'Foo Bar Metro',
-		short: 'M'
-	}
-}
-```
-
-Let's break this down:
-
-- `product`: A sensible, [camelCased](https://en.wikipedia.org/wiki/Camel_case#Variations_and_synonyms), alphanumeric identifier. Use it for the key in the `products` object as well.
-- `mode`: A [valid *Friendly Public Transport Format* `1.0.1` mode](https://github.com/public-transport/friendly-public-transport-format/blob/1.0.1/spec/readme.md#modes).
-- `bitmask`: HAFAS endpoints work with a [bitmask](https://en.wikipedia.org/wiki/Mask_(computing)#Arguments_to_functions) that toggles the individual products. the value should toggle the appropriate bit(s) in the bitmask (see below).
-- `name`: A short, but distinct name for the means of transport, *just precise enough in local context*, and in the local language. In Berlin, `S-Bahn-Schnellzug` would be too much, because everyone knows what `S-Bahn` means.
-- `short`: The shortest possible symbol that identifies the product.
-
-todo: `defaultProducts`, `allProducts`, `bitmasks`, add to profile
-
-If you want, you can now **verify that the profile works**; We've prepared [a script](https://runkit.com/derhuerst/hafas-client-profile-example) for that. Alternatively, [submit a Pull Request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) and we will help you out with testing and improvements.
-
-### Finding the right values for the `bitmask` field
-
-As shown in [the video](https://stuff.jannisr.de/how-to-record-hafas-requests.mp4), search for a journey and toggle off one product at a time, recording the requests. After extracting the products bitmask ([example](https://gist.github.com/derhuerst/193ef489f8aa50c2343f8bf1f2a22069#file-via-http-L34)) you will end up with values looking like these:
-
-```
-toggles                     value  binary  subtraction     bit(s)
-all products                31     11111   31 - 0
-all but ACME Commuter Rail  15     01111   31 - 2^4        2^4
-all but Foo Bar Metro       23     10111   31 - 2^3        2^3
-all but product E           30     11001   31 - 2^2 - 2^1  2^2, 2^1
-all but product F           253    11110   31 - 2^1        2^0
-```
-
-## 4. Additional info
-
-We consider these improvements to be *optional*:
-
-- **Check if the endpoint supports the journey legs call.**
-	- In the app, check if you can query details for the status of a single journey leg. It should load realtime delays and the current progress.
-	- If this feature is supported, add `journeyLeg: true` to the profile.
-- **Check if the endpoint supports the live map call.** Does the app have a "live map" showing all vehicles within an area? If so, add `radar: true` to the profile.
--  **Consider transforming station & line names** into the formats that's most suitable for *local users*. Some examples:
-	- `M13 (Tram)` -> `M13`. With Berlin context, it is obvious that `M13` is a tram.
-	- `Berlin Jungfernheide Bhf` -> `Berlin Jungfernheide`. With local context, it's obvious that *Jungfernheide* is a train station.
-- **Check if the endpoint has non-obvious limitations** and let use know about these. Examples:
-	- Some endpoints have a time limit, after which they won't return more departures, but silently discard them.

-## Appendix A: `checksum`, `mic`, `mac`
-
-As far as we know, there are three different types of authentication used among HAFAS deployments.
-
-### unprotected endpoints
-
-You can just query these, as long as you send a formally correct request.
-
-### endpoints using the `checksum` query parameter
-
-`checksum` is a [message authentication code](https://en.wikipedia.org/wiki/Message_authentication_code): `hafas-client` will compute it by [hashing](https://en.wikipedia.org/wiki/Hash_function) the request body and a secret *salt*. **This secret can be read from the config file inside the app bundle.** There is no guide for this yet, so please [open an issue](https://github.com/derhuerst/hafas-client/issues/new) instead.
-
-### endpoints using the `mic` & `mac` query parameters
-
-`mic` is a [message integrity code](https://en.wikipedia.org/wiki/Message_authentication_code), the [hash](https://en.wikipedia.org/wiki/Hash_function) of the request body.
-
-`mac` is a [message authentication code](https://en.wikipedia.org/wiki/Message_authentication_code), the hash of `mic` and a secret *salt*. **This secret can be read from the config file inside the app bundle.** There is no guide for this yet, so please [open an issue](https://github.com/derhuerst/hafas-client/issues/new) instead.
