# @json-render/codegen
Framework-agnostic utilities for generating code from json-render UI trees. Use these to build custom code exporters for Next.js, Remix, or other frameworks.
## Installation
```bash
npm install @json-render/codegen
```
## Tree Traversal
```typescript
import {
traverseSpec,
collectUsedComponents,
collectStatePaths,
collectActions,
} from "@json-render/codegen";
// Walk the spec depth-first
traverseSpec(spec, (element, key, depth, parent) => {
console.log(`${" ".repeat(depth * 2)}${key}: ${element.type}`);
});
// Get all component types used
const components = collectUsedComponents(spec);
// Set { "Card", "Metric", "Button" }
// Get all state paths referenced
const statePaths = collectStatePaths(spec);
// Set { "analytics/revenue", "user/name" }
// Get all action names
const actions = collectActions(spec);
// Set { "submit_form", "refresh_data" }
```
## Serialization
```typescript
import {
serializePropValue,
serializeProps,
escapeString,
type SerializeOptions,
} from "@json-render/codegen";
// Serialize a single value
serializePropValue("hello");
// { value: '"hello"', needsBraces: false }
serializePropValue({ $state: "/user/name" });
// { value: '{ $state: "/user/name" }', needsBraces: true }
// Serialize props for JSX
serializeProps({ title: "Dashboard", columns: 3, disabled: true });
// 'title="Dashboard" columns={3} disabled'
// Escape strings for code
escapeString('hello "world"');
// 'hello \"world\"'
```
### SerializeOptions
```typescript
interface SerializeOptions {
quotes?: "single" | "double";
indent?: number;
}
```
## Types
```typescript
import type { GeneratedFile, CodeGenerator } from "@json-render/codegen";
const myGenerator: CodeGenerator = {
generate(spec) {
return [
{ path: "package.json", content: "..." },
{ path: "app/page.tsx", content: "..." },
];
},
};
```
## Building a Custom Generator
```typescript
import {
collectUsedComponents,
collectStatePaths,
traverseSpec,
serializeProps,
type GeneratedFile,
} from "@json-render/codegen";
import type { Spec } from "@json-render/core";
export function generateNextJSProject(spec: Spec): GeneratedFile[] {
const files: GeneratedFile[] = [];
const components = collectUsedComponents(spec);
// Generate package.json, component files, main page...
return files;
}

Questions
What does the codegen — vercel-labs/json-render skill do?
The Generative UI framework
Is codegen — vercel-labs/json-render safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can codegen — vercel-labs/json-render access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
How current is this page?
The grade is for one exact copy of the source (6e433eb9a71f), read on 2026-10-20. The repository is watched, and a new audit runs when it changes — this is the first audit.
