Use chat to continue your UI as if you're coding it. Engineers can use it to draft up several pages to copy as pages into your main code base. If starting from scratch, you can export the preview to CodeSandbox, where you can develop within a devbox or initiate a Github Repo. The code generated by Nextjs Page Generator is styled with [TailwindCSS](https://tailwindcss.com/) or plain inline CSS. 4 | 5 | Screenshot 2024-03-02 165534 6 | 7 | ## Goals 8 | 9 | The goal of this project is to have a playground for frontend developers to quickly generate and tweak and export AI generated UI. In the current state it supports TailwindCSS and plain inline CSS but this could easily be extended with prompting. 10 | 11 | Future investments includes: 12 | - Support for other styling frameworks (Shadcn imports TSX & Stackblitz) 13 | - Auto-save and deploy projects to Vercel or Netlify 14 | - Provide context to an existing project that needs to be extended 15 | 16 | ## Getting Started 17 | 18 | Install dependencies with `yarn`, `npm` or `pnpm`. 19 | 20 | 21 | Set your OpenAI key by running the setup script `./setup.sh`. 22 | Or by editing `.env.local` if you're running this code locally. 23 | 24 | Then run the development server: 25 | 26 | ```bash 27 | npm run dev 28 | # or 29 | yarn dev 30 | # or 31 | pnpm dev 32 | ``` 33 | Open [http://localhost:3000](http://localhost:3000) with your browser to see the result. 34 | 35 | ### Demos 36 | For example, this page was generated with a single a prompt and included the axios request setup: 37 | Screenshot 2024-03-02 004705 38 | 39 |
