pnpm add <UNSET>

bun add <UNSET>

yarn add <UNSET> zod

# Note that Yarn does not install peer dependencies automatically. You will need
# to install zod as shown above.

For supported JavaScript runtimes, please consult RUNTIMES.md.

import { TrainTravel } from "train-travel";

const trainTravel = new TrainTravel({
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    const result = await trainTravel.stations.getStations({
        page: 1,
        coordinates: "52.5200,13.4050",
        search: "Milano Centrale",
    });

    // Handle the result
    console.log(result);
}

run();

• getStations - Get a list of train stations

• getTrips - Get available train trips

• getBookings - List existing bookings
• createBooking - Create a booking
• getBooking - Get a booking
• deleteBooking - Delete a booking

• createBookingPayment - Pay for a Booking

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

To read more about standalone functions, check FUNCTIONS.md.

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

import { TrainTravel } from "train-travel";

const trainTravel = new TrainTravel({
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    const result = await trainTravel.stations.getStations(
        {
            page: 1,
            coordinates: "52.5200,13.4050",
            search: "Milano Centrale",
        },
        {
            retries: {
                strategy: "backoff",
                backoff: {
                    initialInterval: 1,
                    maxInterval: 50,
                    exponent: 1.1,
                    maxElapsedTime: 100,
                },
                retryConnectionErrors: false,
            },
        }
    );

    // Handle the result
    console.log(result);
}

run();

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

import { TrainTravel } from "train-travel";

const trainTravel = new TrainTravel({
    retryConfig: {
        strategy: "backoff",
        backoff: {
            initialInterval: 1,
            maxInterval: 50,
            exponent: 1.1,
            maxElapsedTime: 100,
        },
        retryConnectionErrors: false,
    },
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    const result = await trainTravel.stations.getStations({
        page: 1,
        coordinates: "52.5200,13.4050",
        search: "Milano Centrale",
    });

    // Handle the result
    console.log(result);
}

run();

All SDK methods return a response object or throw an error. If Error objects are specified in your OpenAPI Spec, the SDK will throw the appropriate Error type.

Validation errors can also occur when either method arguments or data returned from the server do not match the expected format. The SDKValidationError that is thrown as a result will capture the raw value that failed validation in an attribute called rawValue. Additionally, a pretty() method is available on this error that can be used to log a nicely formatted string since validation errors can list many issues and the plain error string may be difficult read when debugging.

import { TrainTravel } from "train-travel";
import { SDKValidationError } from "train-travel/models/errors";

const trainTravel = new TrainTravel({
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    let result;
    try {
        result = await trainTravel.stations.getStations({
            page: 1,
            coordinates: "52.5200,13.4050",
            search: "Milano Centrale",
        });

        // Handle the result
        console.log(result);
    } catch (err) {
        switch (true) {
            case err instanceof SDKValidationError: {
                // Validation errors can be pretty-printed
                console.error(err.pretty());
                // Raw value may also be inspected
                console.error(err.rawValue);
                return;
            }
            default: {
                throw err;
            }
        }
    }
}

run();

You can override the default server globally by passing a server index to the serverIdx optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:

import { TrainTravel } from "train-travel";

const trainTravel = new TrainTravel({
    serverIdx: 0,
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    const result = await trainTravel.stations.getStations({
        page: 1,
        coordinates: "52.5200,13.4050",
        search: "Milano Centrale",
    });

    // Handle the result
    console.log(result);
}

run();

The default server can also be overridden globally by passing a URL to the serverURL optional parameter when initializing the SDK client instance. For example:

import { TrainTravel } from "train-travel";

const trainTravel = new TrainTravel({
    serverURL: "https://api.example.com",
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    const result = await trainTravel.stations.getStations({
        page: 1,
        coordinates: "52.5200,13.4050",
        search: "Milano Centrale",
    });

    // Handle the result
    console.log(result);
}

run();

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

import { TrainTravel } from "train-travel";
import { HTTPClient } from "train-travel/lib/http";

const httpClient = new HTTPClient({
  // fetcher takes a function that has the same signature as native `fetch`.
  fetcher: (request) => {
    return fetch(request);
  }
});

httpClient.addHook("beforeRequest", (request) => {
  const nextRequest = new Request(request, {
    signal: request.signal || AbortSignal.timeout(5000)
  });

  nextRequest.headers.set("x-custom-header", "custom value");

  return nextRequest;
});

httpClient.addHook("requestError", (error, request) => {
  console.group("Request Error");
  console.log("Reason:", `${error}`);
  console.log("Endpoint:", `${request.method} ${request.url}`);
  console.groupEnd();
});

const sdk = new TrainTravel({ httpClient });

This SDK supports the following security scheme globally:

To authenticate with the API the oAuth2 parameter must be set when initializing the SDK client instance. For example:

import { TrainTravel } from "train-travel";

const trainTravel = new TrainTravel({
    oAuth2: process.env["TRAINTRAVEL_O_AUTH2"] ?? "",
});

async function run() {
    const result = await trainTravel.stations.getStations({
        page: 1,
        coordinates: "52.5200,13.4050",
        search: "Milano Centrale",
    });

    // Handle the result
    console.log(result);
}

run();

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

[!WARNING] Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.

import { TrainTravel } from "train-travel";

const sdk = new TrainTravel({ debugLogger: console });

You can also enable a default debug logger by setting an environment variable TRAINTRAVEL_DEBUG to true.

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
