Generate a Next.js + Express app with AI
IDEA generates a full-stack application on Express with TypeScript and Next.js with TypeScript with MongoDB (Mongoose) from a written brief: the API, data models, authentication and frontend, file by file. This stack is generally available: you can choose it in the stack picker, and it runs the full set of checks.
- Frontend
- Next.js with TypeScript
- Backend
- Express with TypeScript
- Database
- MongoDB (Mongoose)
- Status
- Generally available, in the stack picker
What gets generated
- A Express with TypeScript backend with routes for each module in your brief.
- Data models for MongoDB (Mongoose).
- Sign-up and login.
- A Next.js with TypeScript frontend wired to the API.
It suits SaaS dashboards, internal tools, marketplaces and most CRUD-heavy products where one language across the stack keeps things simple.
How this stack is checked
Generated code for this stack is checked with the real TypeScript compiler, including imports between generated files. Structural validators confirm the required files and routes exist, and a bounded repair pass fixes what the checks report.
This is the stack with the most verification, including a smoke test of the generated app.
Preview and deployment
- Preview: Live preview in the browser.
- The backend runs with Node.js.
- Deploy or export: Vercel, Railway, Render, GitHub or a ZIP download.
Questions, answered
Can AI generate a Express with TypeScript app?
Yes. IDEA generates a Express with TypeScript backend with MongoDB (Mongoose) models, authentication and a Next.js with TypeScript frontend from a written brief. This stack is generally available: you can choose it in the stack picker, and it runs the full set of checks.
Where can I deploy the generated Express with TypeScript app?
You can use Vercel, Railway, Render, GitHub or a ZIP download. The backend runs with Node.js.
Is the generated code mine?
Yes. As between you and IDEA, you own the output generated for your projects, subject to the terms of the underlying AI provider and the licences of the open-source packages the project uses.
