+description: Helps create, configure, and deploy Azure Static Web Apps using the SWA CLI. Use when deploying static sites to Azure, setting up SWA local development, configuring staticwebapp.config.json, adding Azure Functions APIs to SWA, or setting up GitHub Actions CI/CD for Static Web Apps.
+---
+
+## Overview
+
+Azure Static Web Apps (SWA) hosts static frontends with optional serverless API backends. The SWA CLI (`swa`) provides local development emulation and deployment capabilities.
+
+**Key features:**
+- Local emulator with API proxy and auth simulation
+- Framework auto-detection and configuration
+- Direct deployment to Azure
+- Database connections support
+
+**Config files:**
+- `swa-cli.config.json` - CLI settings, **created by `swa init`** (never create manually)
+- `staticwebapp.config.json` - Runtime config (routes, auth, headers, API runtime) - can be created manually
+
+## General Instructions
+
+### Installation
+
+```bash
+npm install -D @azure/static-web-apps-cli
+```
+
+Verify: `npx swa --version`
+
+### Quick Start Workflow
+
+**IMPORTANT: Always use `swa init` to create configuration files. Never manually create `swa-cli.config.json`.**
+
+1. `swa init` - **Required first step** - auto-detects framework and creates `swa-cli.config.json`
+2. `swa start` - Run local emulator at `http://localhost:4280`
+3. `swa login` - Authenticate with Azure
+4. `swa deploy` - Deploy to Azure
+
+### Configuration Files
+
+**swa-cli.config.json** - Created by `swa init`, do not create manually:
+- Run `swa init` for interactive setup with framework detection
+- Run `swa init --yes` to accept auto-detected defaults
+- Edit the generated file only to customize settings after initialization
+
+Example of generated config (for reference only):
+```json
+{
+  "$schema": "https://aka.ms/azure/static-web-apps-cli/schema",
+  "configurations": {
+    "app": {
+      "appLocation": ".",
+      "apiLocation": "api",
+      "outputLocation": "dist",
+      "appBuildCommand": "npm run build",
+      "run": "npm run dev",
+      "appDevserverUrl": "http://localhost:3000"
+    }
+  }
+}
+```
+
+**staticwebapp.config.json** (in app source or output folder) - This file CAN be created manually for runtime configuration:
+```json
+{
+  "navigationFallback": {
+    "rewrite": "/index.html",
+    "exclude": ["/images/*", "/css/*"]
+  },
+  "routes": [
+    { "route": "/api/*", "allowedRoles": ["authenticated"] }
+  ],
+  "platform": {
+    "apiRuntime": "node:20"
+  }
+}
+```
+
+## Command-line Reference
+

+
+Initialize database connections.
+
+```bash
+swa db init --database-type mssql
+swa db init --database-type postgresql
+swa db init --database-type cosmosdb_nosql
+```
+
+## Scenarios
+
+### Create SWA from Existing Frontend and Backend
+
+**Always run `swa init` before `swa start` or `swa deploy`. Do not manually create `swa-cli.config.json`.**
+
+```bash
+# 1. Install CLI
+npm install -D @azure/static-web-apps-cli
+
+# 2. Initialize - REQUIRED: creates swa-cli.config.json with auto-detected settings
+npx swa init              # Interactive mode
+# OR
+npx swa init --yes        # Accept auto-detected defaults
+
+# 3. Build application (if needed)
+npm run build
+
+# 4. Test locally (uses settings from swa-cli.config.json)
+npx swa start
+
+# 5. Deploy
+npx swa login
+npx swa deploy --env production
+```
+
+### Add Azure Functions Backend
+
+1. **Create API folder:**
+```bash
+mkdir api && cd api
+func init --worker-runtime node --model V4
+func new --name message --template "HTTP trigger"
+```
+
+2. **Example function** (`api/src/functions/message.js`):
+```javascript
+const { app } = require('@azure/functions');
+
+app.http('message', {
+    methods: ['GET', 'POST'],
+    authLevel: 'anonymous',
+    handler: async (request) => {
+        const name = request.query.get('name') || 'World';
+        return { jsonBody: { message: `Hello, ${name}!` } };
+    }
+});
+```
+
+3. **Set API runtime** in `staticwebapp.config.json`:
+```json
+{
+  "platform": { "apiRuntime": "node:20" }
+}
+```
+
+4. **Update CLI config** in `swa-cli.config.json`:
+```json
+{
+  "configurations": {
+    "app": { "apiLocation": "api" }
+  }
+}
+```
+
+5. **Test locally:**
+```bash
+npx swa start ./dist --api-location ./api
+# Access API at http://localhost:4280/api/message
+```
+
+**Supported API runtimes:** `node:18`, `node:20`, `node:22`, `dotnet:8.0`, `dotnet-isolated:8.0`, `python:3.10`, `python:3.11`
+
+### Set Up GitHub Actions Deployment
+
+1. **Create SWA resource** in Azure Portal or via Azure CLI
+2. **Link GitHub repository** - workflow auto-generated, or create manually:
+
+`.github/workflows/azure-static-web-apps.yml`:
+```yaml
+name: Azure Static Web Apps CI/CD
+
+on:
+  push:
+    branches: [main]
+  pull_request:
+    types: [opened, synchronize, reopened, closed]
+    branches: [main]
+
+jobs:
+  build_and_deploy:
+    if: github.event_name == 'push' || (github.event_name == 'pull_request' && github.event.action != 'closed')
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - name: Build And Deploy
+        uses: Azure/static-web-apps-deploy@v1
+        with:
+          azure_static_web_apps_api_token: ${{ secrets.AZURE_STATIC_WEB_APPS_API_TOKEN }}
+          repo_token: ${{ secrets.GITHUB_TOKEN }}
+          action: upload
+          app_location: /
+          api_location: api
+          output_location: dist
+
+  close_pr:
+    if: github.event_name == 'pull_request' && github.event.action == 'closed'
+    runs-on: ubuntu-latest
+    steps:
+      - uses: Azure/static-web-apps-deploy@v1
+        with:
+          azure_static_web_apps_api_token: ${{ secrets.AZURE_STATIC_WEB_APPS_API_TOKEN }}
+          action: close
+```
+
+3. **Add secret:** Copy deployment token to repository secret `AZURE_STATIC_WEB_APPS_API_TOKEN`
+
+**Workflow settings:**
+- `app_location` - Frontend source path
+- `api_location` - API source path
+- `output_location` - Built output folder
+- `skip_app_build: true` - Skip if pre-built
+- `app_build_command` - Custom build command
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| 404 on client routes | Add `navigationFallback` with `rewrite: "/index.html"` to `staticwebapp.config.json` |
+| API returns 404 | Verify `api` folder structure, ensure `platform.apiRuntime` is set, check function exports |
+| Build output not found | Verify `output_location` matches actual build output directory |
+| Auth not working locally | Use `/.auth/login/<provider>` to access auth emulator UI |
+| CORS errors | APIs under `/api/*` are same-origin; external APIs need CORS headers |
+| Deployment token expired | Regenerate in Azure Portal → Static Web App → Manage deployment token |
+| Config not applied | Ensure `staticwebapp.config.json` is in `app_location` or `output_location` |
+| Local API timeout | Default is 45 seconds; optimize function or check for blocking calls |
+
+**Debug commands:**
+```bash
+swa start --verbose log        # Verbose output
+swa deploy --dry-run           # Preview deployment
+swa --print-config             # Show resolved configuration
+```
