vite-plugin-jsx-loc

A Vite plugin that adds location data attributes to JSX elements for debugging and development purposes.

Installation

npm install @builder.io/vite-plugin-jsx-loc
# or
yarn add @builder.io/vite-plugin-jsx-loc
# or
pnpm add @builder.io/vite-plugin-jsx-loc

Usage

Add the plugin to your vite.config.ts:

import { defineConfig } from 'vite';
import { jsxLocPlugin } from '@builder.io/vite-plugin-jsx-loc';

export default defineConfig({
  plugins: [jsxLocPlugin()],
});

This will add a data-loc attribute to all JSX elements in your code, containing the relative file path and line number where the element is defined. For example:

// Input: src/components/Button.tsx
export function Button() {
  return <button>Click me</button>;
}

// Output (during development):
export function Button() {
  return <button data-loc="src/components/Button.tsx:2">Click me</button>;
}

Features

• Adds source location information to JSX elements
• Works with both .jsx and .tsx files
• Skips processing of node_modules
• Preserves source maps
• Minimal performance impact
• No configuration required
