React Email renderer for json-render that turns JSON specs into HTML or plain-text emails using @react-email/components and @react-email/render. Use when working with @json-render/react-email, building transactional or marketing emails from JSON, creating email catalogs, rendering AI-generated email specs, or when the user mentions react-email, HTML email, or transactional email.

使用 React Email 组件将 JSON 邮件规格渲染为 HTML 或纯文本邮件。

功能
该技能介绍 @json-render/react-email,这是一个将 JSON 元素树规格转换为 HTML 或纯文本邮件输出的渲染器。内容涵盖规格结构、使用 Zod 类型组件创建目录与注册表,以及服务端渲染函数 renderToHtml 和 renderToPlainText。还列出了用于结构、布局、内容和工具的标准组件,以及邮件客户端兼容性实践。
适用场景
适用于从 JSON 规格构建事务性邮件或营销邮件、定义邮件目录,或渲染 AI 生成的邮件规格。当用户提到 react-email、HTML 邮件或事务性邮件时也可使用。
运行要求
需要在 JavaScript 或 TypeScript 项目中安装 @json-render/react-email 包,以及 @json-render/core、@react-email/components、@react-email/render 和 zod。该技能不附带脚本,仅为说明文档。

@json-render/react-email

React Email renderer that converts JSON specs into HTML or plain-text email output.

Quick Start

typescript
import { renderToHtml } from "@json-render/react-email";import { schema, standardComponentDefinitions } from "@json-render/react-email";import { defineCatalog } from "@json-render/core";
const catalog = defineCatalog(schema, {  components: standardComponentDefinitions,});
const spec = {  root: "html-1",  elements: {    "html-1": { type: "Html", props: { lang: "en", dir: "ltr" }, children: ["head-1", "body-1"] },    "head-1": { type: "Head", props: {}, children: [] },    "body-1": {      type: "Body",      props: { style: { backgroundColor: "#f6f9fc" } },      children: ["container-1"],    },    "container-1": {      type: "Container",      props: { style: { maxWidth: "600px", margin: "0 auto", padding: "20px" } },      children: ["heading-1", "text-1"],    },    "heading-1": { type: "Heading", props: { text: "Welcome" }, children: [] },    "text-1": { type: "Text", props: { text: "Thanks for signing up." }, children: [] },  },};
const html = await renderToHtml(spec);

Spec Structure (Element Tree)

Same flat element tree as @json-render/react: root key plus elements map. Root must be Html; children of Html should be Head and Body. Use Container (e.g. max-width 600px) inside Body for client-safe layout.

Creating a Catalog and Registry

typescript
import { defineCatalog } from "@json-render/core";import { schema, defineRegistry, renderToHtml } from "@json-render/react-email";import { standardComponentDefinitions } from "@json-render/react-email/catalog";import { Container, Heading, Text } from "@react-email/components";import { z } from "zod";
const catalog = defineCatalog(schema, {  components: {    ...standardComponentDefinitions,    Alert: {      props: z.object({        message: z.string(),        variant: z.enum(["info", "success", "warning"]).nullable(),      }),      slots: [],      description: "A highlighted message block",    },  },  actions: {},});
const { registry } = defineRegistry(catalog, {  components: {    Alert: ({ props }) => (      <Container style={{ padding: 16, backgroundColor: "#eff6ff", borderRadius: 8 }}>        <Text style={{ margin: 0 }}>{props.message}</Text>      </Container>    ),  },});
const html = await renderToHtml(spec, { registry });

Server-Side Render APIs

FunctionPurpose
renderToHtml(spec, options?)Render spec to HTML email string
renderToPlainText(spec, options?)Render spec to plain-text email string

RenderOptions: registry, includeStandard (default true), state (for $state / $cond).

Visibility and State

Supports visible conditions, $state, $cond, repeat (repeat.statePath), nested repeat paths with { "$item": "field" }, and the same expression syntax as @json-render/react. Use state in RenderOptions when rendering server-side so expressions resolve.

Server-Safe Import

Import schema and catalog without React or @react-email/components:

typescript
import { schema, standardComponentDefinitions } from "@json-render/react-email/server";

Key Exports

ExportPurpose
defineRegistryCreate type-safe component registry from catalog
RendererRender spec in browser (e.g. preview); use with JSONUIProvider for state/actions
createRendererStandalone renderer component with state/actions/validation
renderToHtmlServer: spec to HTML string
renderToPlainTextServer: spec to plain-text string
schemaEmail element schema
standardComponentsPre-built component implementations
standardComponentDefinitionsCatalog definitions (Zod props)

Sub-path Exports

PathPurpose
@json-render/react-emailFull package
@json-render/react-email/serverSchema and catalog only (no React)
@json-render/react-email/catalogStandard component definitions and types
@json-render/react-email/renderRender functions only

Standard Components

All components accept a style prop (object) for inline styles. Use inline styles for email client compatibility; avoid external CSS.

Document structure

ComponentDescription
HtmlRoot wrapper (lang, dir). Children: Head, Body.
HeadEmail head section.
BodyBody wrapper; use style for background.

Layout

ComponentDescription
ContainerConstrain width (e.g. max-width 600px).
SectionGroup content; table-based for compatibility.
RowHorizontal row.
ColumnColumn in a Row; set width via style.

Content

ComponentDescription
HeadingHeading text (as: h1–h6).
TextBody text.
LinkHyperlink (text, href).
ButtonCTA link styled as button (text, href).
ImageImage from URL (src, alt, width, height).
HrHorizontal rule.

Utility

ComponentDescription
PreviewInbox preview text (inside Html).
MarkdownMarkdown content as email-safe HTML.

Email Best Practices

  • Keep width constrained (e.g. Container max-width 600px).
  • Use inline styles or React Email's style props; many clients strip <style> blocks.
  • Prefer table-based layout (Section, Row, Column) for broad client support.
  • Use absolute URLs for images; many clients block relative or cid: references in some contexts.
  • Test in multiple clients (Gmail, Outlook, Apple Mail); use a preview tool or Litmus-like service when possible.
