@serve.zone/platformclient is the application SDK for serve.zone platform services. It opens a TypedSocket connection to a platform endpoint and gives application code focused connectors for transactional email, SMS, push notifications, and physical letters without hand-writing TypedRequest setup.

Install

pnpm add @serve.zone/platformclient

Quick Start

import { SzPlatformClient } from '@serve.zone/platformclient';

const platformClient = new SzPlatformClient({
  token: process.env.SERVEZONE_PLATFORM_TOKEN,
  platformUrl: process.env.SERVEZONE_PLATFORM_URL,
});

await platformClient.init();

await platformClient.emailConnector.sendEmail({
  to: 'user@example.com',
  from: 'hello@example.com',
  title: 'Workspace ready',
  body: 'Your serve.zone workspace is ready.',
});

Connectors

SzPlatformClient owns the shared connection and exposes connector instances:

Connector	Main methods	Platform capability
`emailConnector`	`sendEmail()`	`email`
`smsConnector`	`sendSms()`, `sendSmsVerifcation()`	`sms`
`pushNotificationConnector`	`sendPushNotification()`	`pushnotification`
`letterConnector`	`sendLetter()`	`letter`

The request and response payloads come from @serve.zone/interfaces, so TypeScript stays aligned with the serve.zone platform contracts.

Configuration

The client needs an authorization string and a platform endpoint. You can provide both directly, through environment variables, or through platform bindings.

Value	Sources
Authorization	Constructor string, `authorizationString`, `authorization`, `token`, `init()` argument, `SERVEZONE_PLATFORM_AUTHORIZATION`, `SERVEZONE_PLATFORM_TOKEN`, or binding credentials.
Platform URL	`url`, `platformUrl`, `SERVEZONE_PLATFORM_URL`, or the first active binding endpoint using `typedrequest` or `http`.
Platform bindings	Constructor `binding` or `bindings`, `SERVEZONE_PLATFORM_BINDING`, or `SERVEZONE_PLATFORM_BINDINGS`.

Binding environment variables must contain JSON encoded IPlatformBinding objects from @serve.zone/interfaces.

import { SzPlatformClient } from '@serve.zone/platformclient';

const client = new SzPlatformClient(process.env.SERVEZONE_PLATFORM_AUTHORIZATION);
await client.init();

import { SzPlatformClient } from '@serve.zone/platformclient';

const client = new SzPlatformClient({
  authorization: process.env.SERVEZONE_PLATFORM_AUTHORIZATION,
  url: process.env.SERVEZONE_PLATFORM_URL,
});

await client.init();

Debug Mode

Pass test as the authorization string to activate debug mode. In debug mode, the client does not open a TypedSocket connection. Connector methods log or return deterministic test values instead of sending real platform requests.

const client = new SzPlatformClient('test');
await client.init();

await client.emailConnector.sendEmail({
  to: 'developer@example.com',
  from: 'hello@example.com',
  title: 'Preview only',
  body: 'This message is logged, not sent.',
});

const verificationCode = await client.smsConnector.sendSmsVerifcation({
  toNumber: 491234567890,
  fromName: 'ServeZone',
});

console.log(verificationCode); // 123456

The current SMS verification method is spelled sendSmsVerifcation() in code. Use that exact method name until the public API changes.

Connector Examples

Email:

await client.emailConnector.sendEmail({
  to: 'user@example.com',
  from: 'hello@example.com',
  title: 'Invoice ready',
  body: 'Your invoice is available in the dashboard.',
});

SMS:

const status = await client.smsConnector.sendSms({
  toNumber: 491234567890,
  fromName: 'ServeZone',
  messageText: 'Your code is 123456.',
});

Push notification:

const status = await client.pushNotificationConnector.sendPushNotification({
  deviceToken: 'device-token-from-your-app',
  message: 'Deployment complete: your service is live.',
});

Letter:

await client.letterConnector.sendLetter({
  description: 'Important account information',
  needsCover: true,
  title: 'Account update',
  coverBody: 'This letter was generated through serve.zone.',
  service: ['Einschreiben'],
});

Exact fields are defined in @serve.zone/interfaces under platform.email, platform.sms, platform.pushnotification, and platform.letter.

Platform Bindings

Platform bindings allow a workload to discover endpoint URLs and credentials from its runtime environment.

import { SzPlatformClient } from '@serve.zone/platformclient';
import { platform } from '@serve.zone/interfaces';

const binding: platform.IPlatformBinding = JSON.parse(
  process.env.SERVEZONE_PLATFORM_BINDING!
);

const client = new SzPlatformClient({ binding });
await client.init();

const emailBinding = client.getPlatformBinding('email');

Bindings with desiredState: 'disabled' or status: 'failed' are ignored when the client auto-selects an endpoint.

InfoHtml Helper

The repository also contains a small ts_infohtml source folder for rendering simple informational HTML pages from text or options. It is not exported from the package root, so treat it as a source-level helper rather than the main SDK API.

Development

pnpm install
pnpm test
pnpm run build

The package is authored as ESM TypeScript and builds source folders with tsbuild tsfolders --web --allowimplicitany.
