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

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
.

```
swa init
```
- Required first step - auto-detects framework and creates
```
swa-cli.config.json
```
```
swa start
```
- Run local emulator at
```
http://localhost:4280
```
```
swa login
```
- Authenticate with Azure
```
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):

{
  "$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:

{
  "navigationFallback": {
    "rewrite": "/index.html",
    "exclude": ["/images/*", "/css/*"]
  },
  "routes": [
    { "route": "/api/*", "allowedRoles": ["authenticated"] }
  ],
  "platform": {
    "apiRuntime": "node:20"
  }
}

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
.

# 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

Create API folder:

mkdir api && cd api
func init --worker-runtime node --model V4
func new --name message --template "HTTP trigger"

Example function (
```
api/src/functions/message.js
```
):

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}!` } };
    }
});

Set API runtime in
```
staticwebapp.config.json
```
:

{
  "platform": { "apiRuntime": "node:20" }
}

Update CLI config in
```
swa-cli.config.json
```
:

{
  "configurations": {
    "app": { "apiLocation": "api" }
  }
}

Test locally:

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

Create SWA resource in Azure Portal or via Azure CLI
Link GitHub repository - workflow auto-generated, or create manually:

.github/workflows/azure-static-web-apps.yml

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

          repo_token: ${{ secrets.GITHUB_TOKEN }}
          action: upload
          app_location: /
          api_location: api

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:

swa start --verbose log        # Verbose output
swa deploy --dry-run           # Preview deployment
swa --print-config             # Show resolved configuration
