@veryfront/ext-parser-babel

Category: Build | Contract: CodeParser | Built-in

Provides JavaScript/TypeScript AST parsing, traversal, and JSX source-position injection for Veryfront, backed by @babel/parser, @babel/traverse, @babel/generator, and @babel/types. Used by the transform pipeline and Studio Navigator.

Registration

This extension is auto-enabled by core bootstrap. Add it to veryfront.config.ts only when you need to override the built-in registration:

import extBabel from "@veryfront/ext-parser-babel";

export default defineConfig({
  extensions: [extBabel()],
});

Provided contract

CodeParser — exposes:

• parse(source, options) / traverse(ast, visitor) / generate(ast, options) — generic AST pipeline for callers that want to build custom transforms.
• injectJsxNodePositions(source, options) — the Studio Navigator helper that stamps data-node-* attributes onto JSX elements at compile time.

Core's src/transforms/plugins/babel-node-positions.ts is a thin shim that resolves this contract at call time. When the extension is not installed and the shim is invoked, Veryfront throws an install-suggestion error directing the user to add @veryfront/ext-parser-babel.

Configuration

No factory options. The extension reads no environment variables and takes no config.
