# Advanced Plugin Techniques

### Wrapping Other Plugins

You can create a plugin that combines multiple plugins:

```javascript
export function configure(config) {
  // Load and configure multiple plugins
  config.plugin(PLATFORM.moduleName('aurelia-animator-css'));
  
  config.plugin(PLATFORM.moduleName('aurelia-dialog'), dialogConfig => {
    dialogConfig.useDefaults();
    dialogConfig.settings.lock = true;
    dialogConfig.settings.ignoreTransitions = true;
  });
}
```

### Modifying Dependency Injection Behavior

Override default DI behavior:

```javascript
import { MyService } from './my-service';

export function configure(config) {
  // Create a new instance for each injection
  config.transient(MyService, MyService);

  // Singleton with a custom implementation
  config.singleton(CustomLogger, class {
    constructor() {
      // Custom singleton logic
    }
  });
}
```

### Configuration Options

Create a configurable plugin:

```javascript
export function configure(config, callback) {
  const pluginConfig = {
    // Default configuration
    option1: false,
    option2: 'default value'
  };

  // Allow external configuration
  if (typeof callback === 'function') {
    callback(pluginConfig);
  }

  // Apply configuration
  config.container.registerInstance('MyPluginConfig', pluginConfig);
}
```

Usage in an app:

```javascript
aurelia.use.plugin('my-plugin', config => {
  config.option1 = true;
  config.option2 = 'custom value';
});
```

### Dynamic Resource Registration

Dynamically register resources based on configuration:

```javascript
export function configure(config, callback) {
  const resources = [];

  // Configurable resource registration
  function registerResource(resourcePath) {
    resources.push(PLATFORM.moduleName(resourcePath));
  }

  // Allow external configuration
  if (typeof callback === 'function') {
    callback(registerResource);
  }

  // Register all collected resources
  config.globalResources(resources);
}
```

### Plugin Composition

Create a plugin that composes multiple sub-plugins:

```javascript
import { UIPlugin } from './ui-plugin';
import { DataPlugin } from './data-plugin';

export function configure(config) {
  // Compose multiple plugin configurations
  config.plugin(PLATFORM.moduleName('./ui-plugin'));
  config.plugin(PLATFORM.moduleName('./data-plugin'));
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://aurelia-1.gitbook.io/v1-docs/developer-guides/building-plugins/advanced-plugin-techniques.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
