Integrate SwaggerUI into Vue 3 — and extend it like a Jedi Dev

Integrating Swagger UI into a Vue 3 application involves installing the package and initializing it in the Vue application. The SwaggerUI package is initialized in the onMounted lifecycle hook to ensure the DOM is fully rendered before mounting SwaggerUI into the UI. The SwaggerUI instance can be configured with an Open API specification file or a server URL. Creating a custom plugin involves wrapping existing UI components or creating new ones to customize SwaggerUI. SwaggerUI is built on React, so plugins must also be built with React. The plugin structure involves creating a function that returns an object containing components to wrap. To sync state between the Vue application and a plugin, a new state is defined, and an action is dispatched to set the characters. The state is then selected from the store and used to render a CharacterCard component. To type the plugins, the tsconfig.json file must be configured to allow synthetic default imports and esModuleInterop. Finally, typing the SwaggerUI instance and system param involves creating interfaces for the SwaggerUI instance and system param.
