Public API

createConfiguration

function createConfiguration(conf: ConfigurationParameters): Configuration;

Factory that builds a Configuration object from partial parameters. Pass restApiKey for most endpoints or organizationApiKey for org-level operations. Defaults: baseServer = server1 (https://api.onesignal.com), empty middleware array, isomorphic fetch HTTP adapter.

DefaultApi

class DefaultApi {
  constructor(configuration: Configuration);
  createNotification(notification: Notification): Promise<CreateNotificationSuccessResponse>;
  getNotification(appId: string, notificationId: string): Promise<NotificationWithMeta>;
  getApp(appId: string): Promise<App>;
  // ...many more endpoints; see DefaultApi.md
}

The primary API client. Instantiate it with a Configuration and call its methods to interact with every OneSignal REST endpoint. All methods return Promises.

Middleware / PromiseMiddleware

interface PromiseMiddleware {
  pre(context: RequestContext): Promise<RequestContext>;
  post(context: ResponseContext): Promise<ResponseContext>;
}

Use these interfaces to intercept outgoing requests (e.g. to log, mutate headers) or incoming responses (e.g. to log errors, transform payloads). Pass instances via ConfigurationParameters.promiseMiddleware.

Working examples

Scenario - Send a push notification to all subscribers

Create a Notification model, set the required fields, and call createNotification. The response includes the OneSignal notification ID for tracking.

import { createConfiguration, DefaultApi, Notification } from '../source/index';

const config = createConfiguration({
  restApiKey: process.env.ONESIGNAL_REST_API_KEY!,
});
const client = new DefaultApi(config);

async function sendPush(): Promise<void> {
  const notification = new Notification();
  notification.app_id = process.env.ONESIGNAL_APP_ID!;
  notification.contents = { en: 'Hello from the server!' };
  notification.headings = { en: 'New Alert' };
  notification.included_segments = ['Subscribed Users'];

  const response = await client.createNotification(notification);
  console.log('Created notification ID:', response.id);
}

sendPush().catch(console.error);

Scenario - Log all outgoing requests with a PromiseMiddleware

Register a custom PromiseMiddleware to inspect the RequestContext before every API call — useful for debugging or auditing.

import {
  createConfiguration,
  DefaultApi,
  Notification,
} from '../source/index';
import { PromiseMiddleware } from '../source/middleware';
import { RequestContext, ResponseContext } from '../source/http/http';

const loggingMiddleware: PromiseMiddleware = {
  async pre(context: RequestContext): Promise<RequestContext> {
    console.log(`[PRE] ${context.getHttpMethod()} ${context.getUrl()}`);
    return context;
  },
  async post(context: ResponseContext): Promise<ResponseContext> {
    console.log(`[POST] status: ${context.httpStatusCode}`);
    return context;
  },
};

const config = createConfiguration({
  restApiKey: process.env.ONESIGNAL_REST_API_KEY!,
  promiseMiddleware: [loggingMiddleware],
});

const client = new DefaultApi(config);

const n = new Notification();
n.app_id = process.env.ONESIGNAL_APP_ID!;
n.contents = { en: 'Middleware test' };
n.included_segments = ['Test Users'];
client.createNotification(n).then(r => console.log(r.id));

Scenario - Send an email notification

Use the same Notification model but set email_subject, email_body, and channel_for_external_user_ids to target the email channel.

import { createConfiguration, DefaultApi, Notification } from '../source/index';

const config = createConfiguration({
  restApiKey: process.env.ONESIGNAL_REST_API_KEY!,
});
const client = new DefaultApi(config);

async function sendEmail(): Promise<void> {
  const notification = new Notification();
  notification.app_id = process.env.ONESIGNAL_APP_ID!;
  notification.email_subject = 'Your weekly digest';
  notification.email_body = '<h1>Hello!</h1><p>Here is your update.</p>';
  notification.included_segments = ['Subscribed Users'];
  notification.channel_for_external_user_ids = 'email';

  const response = await client.createNotification(notification);
  console.log('Email notification ID:', response.id);
}

sendEmail().catch(console.error);

File walkthrough

• index.ts - Barrel file; re-exports everything the consumer needs (DefaultApi, Notification, createConfiguration, Middleware, etc.).
• configuration.ts - Defines ConfigurationParameters, Configuration interface, and the createConfiguration factory that merges auth, server, and middleware settings.
• middleware.ts - Declares the Middleware (Observable-based) and PromiseMiddleware interfaces; provides PromiseMiddlewareWrapper to bridge them.
• servers.ts - ServerConfiguration generic class for URL template resolution; exports server1 (https://api.onesignal.com) as the default.
• util.ts - Two pure utility functions (isCodeInRange, canConsumeForm) used internally by generated API code.
• rxjsStub.ts - Minimal Observable/from shim so the SDK does not require a full RxJS dependency.
• apis/DefaultApi.ts - All REST endpoint implementations as class methods returning Promises.
• apis/baseapi.ts - Abstract base class for generated API classes; exports RequiredError.
• apis/exception.ts - ApiException class thrown on non-2xx responses.
• auth/auth.ts - configureAuthMethods and supporting types for REST API key and Organization API key schemes.
• http/http.ts - RequestContext, ResponseContext, HttpLibrary interface, and HttpMethod enum.
• http/isomorphic-fetch.ts - Default HttpLibrary implementation using the global fetch.
• models/ - One file per model (e.g. Notification.ts, App.ts); plus ObjectSerializer.ts for (de)serialization.
• types/ - Promise-based API wrappers generated from the Observable-based core; PromiseDefaultApi is exported as DefaultApi.

Common pitfalls and fixes

• Missing fetch in Node < 18 — install node-fetch and assign global.fetch = require('node-fetch') before importing the SDK, or use --experimental-fetch on Node 17.
• btoa not defined — the SDK depends on btoa; in Node < 16 add global.btoa = (str) => Buffer.from(str).toString('base64') at your entry point.
• restApiKey vs organizationApiKey confusion — most app-level endpoints (notifications, users) require restApiKey; org-level endpoints (create/list apps) require organizationApiKey. Passing the wrong key returns a 401 that looks like a network error.
• ESM/CJS interop — if your project uses "type": "module", the SDK ships CommonJS; wrap imports with createRequire or set "moduleResolution": "bundler" in tsconfig and use a bundler like esbuild.
• ApiException not caught — the SDK throws ApiException (from apis/exception.ts) on HTTP errors; catch it explicitly: catch (e) { if (e instanceof ApiException) ... }.
• TypeScript path aliases not resolved at runtime — if you add paths to tsconfig, also configure tsconfig-paths or tsc-alias so compiled JS resolves the aliases; otherwise module not found errors appear at runtime.

Vibe-coding prompt template

I have the OneSignal Node.js Server SDK source code located in `source/` and
its integration guide at `USAGE.md`. The upstream package is
`@onesignal/node-onesignal@5.5.0`.

Please integrate the SDK into my existing project step by step:

1. Read `USAGE.md` in full for correct import paths, types, and examples.
2. Install all required dependencies listed in the "Required dependencies" section.
3. Create a shared client module at `src/onesignalClient.ts` that reads API
   keys from environment variables and exports a configured `DefaultApi` instance.
4. Add a utility function `sendPushNotification(appId, contents, segments)` that
   uses the shared client to call `client.createNotification(...)` and returns
   the notification ID.
5. Add error handling that catches `ApiException` (from `source/apis/exception`)
   and logs the HTTP status code and body.
6. Show me the final file tree of modified/added files.

Do not invent any API methods or types. Only use exports visible in
`source/index.ts` and documented in `USAGE.md`.
