TACHYON Field Extension SDK

SDKs for building TACHYON Field Cloud App extensions.

The first package is the browser SDK used inside Cloud App UI pages embedded by TACHYON Field admin.

import { createFieldExtensionClient } from '@tachyon/field-extension-sdk'

const field = createFieldExtensionClient()

field.frame.ready()

const preview = await field.extensionApi.post('/pricing/preview', {
  courseId: 'weekday',
  subjectCount: 2,
})

The browser SDK reads tenant, extensionAppName, surface, proxyBase, and optional contractVersion=1 from the iframe URL. API calls go through the Field host proxyBase; the SDK appends the tenant query parameter but does not add browser-side credentials or operator headers. The Field host/proxy owns token pass-through.
