Vue 3 renderer for json-render. Use when building Vue UIs from JSON specs, working with @json-render/vue, defining Vue component registries, or rendering AI-generated specs in Vue.

AI 生成的概览

介绍 @json-render/vue 的参考指南，这是一个将 JSON 规格转换为 Vue 组件树的 Vue 3 渲染器。

功能: 该技能介绍 @json-render/vue，这是一个 Vue 3 渲染器，可将 JSON 规格转换为带数据绑定、可见性条件和动作的 Vue 组件树。它说明如何用 Zod schema 定义 catalog、用 Vue h() 渲染函数构建组件注册表，并通过 StateProvider、ActionProvider、VisibilityProvider、ValidationProvider 等 provider 渲染规格。内容还涵盖组合式函数、具名插槽、动态 prop 表达式、内置动作、事件系统、流式辅助函数以及外部状态存储。
适用场景: 适用于从 JSON 规格构建 Vue UI、使用 @json-render/vue、定义 Vue 组件注册表，或在 Vue 中渲染 AI 生成的规格。它是面向集成该渲染器的开发者的参考资料，而非任务工作流。
运行要求: 需要 npm 包 @json-render/vue、@json-render/core 和 zod，以及对等依赖 vue ^3.5.0 与 zod ^4.0.0。不附带脚本，仅为文档。

@json-render/vue

Vue 3 renderer that converts JSON specs into Vue component trees with data binding, visibility, and actions.

Installation

Peer dependencies: vue ^3.5.0 and zod ^4.0.0.

Quick Start

Create a Catalog

typescript

import { defineCatalog } from "@json-render/core";import { schema } from "@json-render/vue/schema";import { z } from "zod";
export const catalog = defineCatalog(schema, {  components: {    Card: {      props: z.object({ title: z.string(), description: z.string().nullable() }),      slots: ["default"],      description: "A card container",    },    Layout: {      props: z.object({}),      slots: ["default", "header", "footer"],      description: "Layout with named content regions",    },    Button: {      props: z.object({ label: z.string(), action: z.string() }),      description: "A clickable button",    },  },  actions: {},});

import { defineCatalog } from "@json-render/core";import { schema } from "@json-render/vue/schema";import { z } from "zod";
export const catalog = defineCatalog(schema, {  components: {    Card: {      props: z.object({ title: z.string(), description: z.string().nullable() }),      slots: ["default"],      description: "A card container",    },    Layout: {      props: z.object({}),      slots: ["default", "header", "footer"],      description: "Layout with named content regions",    },    Button: {      props: z.object({ label: z.string(), action: z.string() }),      description: "A clickable button",    },  },  actions: {},});

Define Registry with h() Render Functions

typescript

import { h } from "vue";import { defineRegistry } from "@json-render/vue";import { catalog } from "./catalog";
export const { registry } = defineRegistry(catalog, {  components: {    Card: ({ props, children }) =>      h("div", { class: "card" }, [        h("h3", null, props.title),        props.description ? h("p", null, props.description) : null,        children,      ]),    Layout: ({ slots }) =>      h("div", null, [        h("header", null, slots.header?.()),        h("main", null, slots.default?.()),        h("footer", null, slots.footer?.()),      ]),    Button: ({ props, emit }) =>      h("button", { onClick: () => emit("press") }, props.label),  },});

import { h } from "vue";import { defineRegistry } from "@json-render/vue";import { catalog } from "./catalog";
export const { registry } = defineRegistry(catalog, {  components: {    Card: ({ props, children }) =>      h("div", { class: "card" }, [        h("h3", null, props.title),        props.description ? h("p", null, props.description) : null,        children,      ]),    Layout: ({ slots }) =>      h("div", null, [        h("header", null, slots.header?.()),        h("main", null, slots.default?.()),        h("footer", null, slots.footer?.()),      ]),    Button: ({ props, emit }) =>      h("button", { onClick: () => emit("press") }, props.label),  },});

Named Slots

Use children for the "default" slot. Use the element's top-level slots object for other slot names declared by the catalog:

json

{  "type": "Layout",  "props": {},  "children": ["main"],  "slots": {    "header": ["heading"],    "footer": ["actions"]  }}

{  "type": "Layout",  "props": {},  "children": ["main"],  "slots": {    "header": ["heading"],    "footer": ["actions"]  }}

Registry components receive Vue-native slot functions. Render them with slots.header?.(), slots.footer?.(), and so on. slots.default?.() renders the spec's children; the children context field is a convenience alias for that rendered result. In the JSON spec, keep default content in children rather than adding a default entry to slots.

Render Specs

vue

<script setup lang="ts">import { StateProvider, ActionProvider, Renderer } from "@json-render/vue";import { registry } from "./registry";
const spec = { root: "card-1", elements: { /* ... */ } };</script>
<template>  <StateProvider :initial-state="{ form: { name: '' } }">    <ActionProvider :handlers="{ submit: handleSubmit }">      <Renderer :spec="spec" :registry="registry" />    </ActionProvider>  </StateProvider></template>

<script setup lang="ts">import { StateProvider, ActionProvider, Renderer } from "@json-render/vue";import { registry } from "./registry";
const spec = { root: "card-1", elements: { /* ... */ } };</script>
<template>  <StateProvider :initial-state="{ form: { name: '' } }">    <ActionProvider :handlers="{ submit: handleSubmit }">      <Renderer :spec="spec" :registry="registry" />    </ActionProvider>  </StateProvider></template>

Providers

Provider	Purpose
`StateProvider`	Share state across components (JSON Pointer paths). Accepts `initialState` or `store` for controlled mode.
`ActionProvider`	Handle actions dispatched via the event system
`VisibilityProvider`	Enable conditional rendering based on state
`ValidationProvider`	Form field validation

Composables

Composable	Purpose
`useStateStore()`	Access state context (`state` as `ShallowRef`, `get`, `set`, `update`)
`useStateValue(path)`	Get single value from state
`useIsVisible(condition)`	Check if a visibility condition is met
`useActions()`	Access action context
`useAction(binding)`	Get a single action dispatch function
`useFieldValidation(path, config)`	Field validation state
`useBoundProp(propValue, bindingPath)`	Two-way binding for `$bindState`/`$bindItem`

Note: useStateStore().state returns a ShallowRef<StateModel> — use state.value to access.

External Store (StateStore)

Nested lists can set repeat.statePath to { "$item": "field" } inside an enclosing repeat.

Pass a StateStore to StateProvider to wire json-render to Pinia, VueUse, or any state management:

typescript

import { createStateStore, type StateStore } from "@json-render/vue";
const store = createStateStore({ count: 0 });

import { createStateStore, type StateStore } from "@json-render/vue";
const store = createStateStore({ count: 0 });

Dynamic Prop Expressions

Props support $state, $bindState, $cond, $template, $computed. Use { "$bindState": "/path" } on the natural value prop for two-way binding.

Visibility Conditions

typescript

{ "$state": "/user/isAdmin" }{ "$state": "/status", "eq": "active" }{ "$state": "/maintenance", "not": true }[ cond1, cond2 ]  // implicit AND

{ "$state": "/user/isAdmin" }{ "$state": "/status", "eq": "active" }{ "$state": "/maintenance", "not": true }[ cond1, cond2 ]  // implicit AND

Built-in Actions

setState, pushState, removeState, and validateForm are built into the Vue schema and handled by ActionProvider:

Event System

Components use emit(event) to fire events, or on(event) for metadata (shouldPreventDefault, bound).

Streaming

useUIStream and useChatUI return Vue Refs for streaming specs from an API.

BaseComponentProps

For catalog-agnostic reusable components:

typescript

import type { BaseComponentProps } from "@json-render/vue";
const Card = ({ props, children }: BaseComponentProps<{ title?: string }>) =>  h("div", null, [props.title, children]);

import type { BaseComponentProps } from "@json-render/vue";
const Card = ({ props, children }: BaseComponentProps<{ title?: string }>) =>  h("div", null, [props.title, children]);

Key Exports

Export	Purpose
`defineRegistry`	Create a type-safe component registry from a catalog
`Renderer`	Render a spec using a registry
`schema`	Element tree schema (from `@json-render/vue/schema`)
`StateProvider`, `ActionProvider`, `VisibilityProvider`, `ValidationProvider`	Context providers
`useStateStore`, `useStateValue`, `useBoundProp`	State composables
`useActions`, `useAction`	Action composables
`useFieldValidation`, `useIsVisible`	Validation and visibility
`useUIStream`, `useChatUI`	Streaming composables
`createStateStore`	Create in-memory `StateStore`
`BaseComponentProps`	Catalog-agnostic component props type
