Генерация email-писем из JSON на React Email

★ 8.1 · content

React Email Template Builder is a Claude Code skill that converts JSON specs into HTML or plain-text email output using @react-email/components and the @json-render/react-email renderer. Reach for it when you need to auto-generate transactional emails — welcome messages, password resets, order confirmations — from structured JSON data, when an AI pipeline produces an email spec on the fly and you need it rendered immediately into client-safe HTML, or when your team maintains a catalog of email components and wants to compose emails declaratively rather than hand-coding HTML tables. Built in TypeScript: a flat element tree (Html → Head + Body → Container → content nodes) is processed server-side by renderToHtml and renderToPlainText; conditional visibility ($cond, $state), repeat loops, and custom components registered via defineRegistry with Zod prop validation are all supported. All styles are inlined for broad email-client compatibility — no external CSS. The @json-render/react-email/server sub-path exposes schema and catalog without pulling React or @react-email/components into server bundles. The skill generates emails from data — it is not a visual drag-and-drop editor or a sending service; delivery still requires an external provider such as Resend or SendGrid.
