Configuration overview

The following different concepts apply to configuring a static web app.

Application configuration: Define rules in the staticwebapp.config.json file to control application behavior and features. Use this file to define route and security rules, custom headers, and networking settings.
Build configuration: Define settings that control the build process.
Application settings: Set application-level settings and environment variables that can be used by backend APIs.

Set which HTML file is served if a route doesn't match an actual file	Define fallback route in the staticwebapp.config.json file
Set global headers for HTTP requests	Define global headers in the staticwebapp.config.json file
Define a custom build command	Set a custom build command value in the application configuration file
