What happened?

When running npm init @code-pushup/cli on a Vite + React project, the setup wizard prompts for target URLs for the Axe and Lighthouse plugins with a default of http://localhost:4200.

That port is correct for Angular/Nx, but Vite serves on http://localhost:5173 by default. Accepting the default (pressing Enter) writes the wrong URL into code-pushup.config.js. Web audits then fail unless the user manually changes the port.

Other wizard plugins already auto-detect project settings (ESLint config, tsconfig, package manager, test framework). Axe and Lighthouse do not — they use a hardcoded default:

• packages/plugin-axe/src/lib/binding.ts → const DEFAULT_URL = 'http://localhost:4200'
• packages/plugin-lighthouse/src/lib/binding.ts → const DEFAULT_URL = 'http://localhost:4200'

What would you expect to happen?

The wizard should detect the likely dev server URL from the project and use it as the default in the Target URL(s) prompt, for example:

• Vite (vite.config.*, no custom port) → http://localhost:5173
• Vite with server.port set → http://localhost:<port>
• Angular/Nx → http://localhost:4200 (or configured port)
• Next.js (next dev in scripts) → http://localhost:3000
• Unknown → fallback to 4200 with a note that the user should confirm

Optionally, the prompt could show where the suggestion came from, e.g.
Target URL(s) (detected from vite.config.js): http://localhost:5173

What steps did you take?

1. Scaffold a Vite + React app:

   npm create vite@latest js-app -- --template react
   cd js-app
   npm install
   git init

2. Run the Code PushUp setup wizard:

   npm init @code-pushup/cli

3. Choose:

   • Setup mode: Standalone
   • Plugins: include Axe and Lighthouse (among others)
   • Config format: JavaScript

4. For both Lighthouse and Axe, accept the default Target URL: http://localhost:4200

5. Finish setup — code-pushup.config.js is created with:

   lighthousePlugin('http://localhost:4200')
   axePlugin('http://localhost:4200', { preset: 'all' })

6. Start the app:

   npm run dev

   App runs at http://localhost:5173/

7. Run Code PushUp:

   npx code-pushup collect

8. Result: web audits target :4200 while the app is on :5173 — audits fail or produce no useful results until the URL is fixed manually.
