# OpenUI Forge — Go Build generative UI apps with a React frontend + Go backend. Streams OpenAI API responses directly via net/http. ## Activation Triggers - "openui go", "openui golang", "openui go backend" - "generative ui go", "go streaming ui backend" ## Prerequisites - Node.js >= 22 (24 LTS recommended) + React >= 18.3.1 (19+ recommended) (frontend) - Go >= 1.24 (backend; 1.23 and older are out of security support as of Go 1.26) - `OPENAI_API_KEY` environment variable set ## Quick Start 1. Create the React frontend and install OpenUI deps: ```bash npm install @openuidev/react-ui @openuidev/react-headless @openuidev/react-lang lucide-react zod ``` 2. Generate the system prompt: ```bash npx @openuidev/cli generate ./src/lib/library.ts --out backend/system-prompt.txt ``` 3. Create the Go backend (see Full Code below) 4. Run: `go run main.go` on `:8080`, frontend on `:3000` ## Full Code ### Backend: `backend/go.mod` ``` module openui-backend go 1.24 require ( github.com/joho/godotenv v1.5.1 ) ``` ### Backend: `backend/main.go` ```go package main import ( "bufio" "bytes" "encoding/json" "fmt" "log" "net/http" "os" _ "github.com/joho/godotenv/autoload" ) var systemPrompt string func init() { data, err := os.ReadFile("system-prompt.txt") if err != nil { log.Fatal("system-prompt.txt not found: ", err) } systemPrompt = string(data) } func corsMiddleware(next http.Handler) http.Handler { return http.HandlerFunc(func(w http.ResponseWriter, r *h
