RailwayAPI NodeJS client

This is an official NPM package that wraps railwayapi API for NodeJS with first class Typescript support.

An example project using this package can be found on Railway Frontend Demo

Installation

Install this package using npm

npm install api-railway

Getting started

Import the module and create a new client. You can pass different base URL, API version, protocol if you want to use different server.

import Client from "api-railway";

const client1 = new Client();

const client2 = new Client({
  BASE_URL: "example.com",
  API_VRSION: "v1",
  DEFAULT_PROTOCOL: "https",
});

Every REST method returns a Promise, making this library async await ready. Following examples will use the await form.

Each REST endpoint returns an object with type ApiReturnType

type ApiRetrunType<
  T extends ApiRetrunDataType,
  U extends ErrorObj = ErrorObj,
  V = {},
> = {
  httpStatusCode: number;
  httpStatusText: string;
  responseType: ResponseType;
  ok: boolean;
  url: string;
  responseHeaders: Headers;
  data: T[] | undefined;
  errors: U[] | undefined;
  raw: any;
  extra?: V;
};

where ApiRetrunDataType is defined as

type ApiRetrunDataType =
  | ScheduleInfo
  | ScheduleRow
  | State
  | StationGeneralInfo
  | StationInfo
  | TrainGeneralInfo
  | TrainInfo
  | TrainsBtwStationsType
  | TrainType
  | Zone;

and ErrorObj is defined as

type ErrorObj = {
  httpCode: number;
  type: string;
  code: string;
  title: string;
  description: string;
  href: string;
  path: string;
  [key: string]: any;
};
