Azion IaC

The azion.config.js file is an IaC configuration file created during the application’s build process, based on the chosen preset, and serves as the source of truth for the configuration. Each preset provides a set of default settings, which can be replaced by the user. If the file is deleted, the default configuration will be recreated the next time the build process is triggered.
