Base44 → Replit

Shim files to read first

  • src/api/base44Client.js, src/api/entities.js, src/api/integrations.js
  • src/lib/app-params.js, src/lib/AuthContext.jsx
  • src/components/ProtectedRoute.jsx, UserNotRegisteredError.jsx
  • vite.config.js

Grep base44.entities.*, base44.integrations.Core.*, base44.auth.* to enumerate what's actually used.

Layout

Flat src/ at repo root → move under client/src/, add server/ + shared/ (FULLSTACK_JS layout). Follow the fullstack-js skill.

Replacements

base44.entities.* javascript_database + drizzle + /api/* routes

UploadFile javascript_object_storage blueprint

Cleanup

Drop @base44/sdk + @base44/vite-plugin. Delete base44Client.js, entities.js, integrations.js, app-params.js, NavigationTracker.jsx, VisualEditAgent.jsx, UserNotRegisteredError.jsx.

First message

One short, non-technical line. Just tell the user a migration is running. No surface enumeration, no plan bullets, no tool / library names. Template:

I've pulled in your Base44 project — looks like *a small business dashboard for tracking revenue, expenses, and customers*. I'll get it running on Replit; this usually takes a few minutes. Nothing needed from you right now.

If you genuinely need a user-supplied secret later, batch it into one request via the environment-secrets skill.
