# @sap/modules-exploration

This is an npm package which provides the ability to explore the available modules/generators installed in a specific predefined folder at runtime.
It provides two main APIs. One to get a list of explored modules and API to display the explored modules to the user in a yeoman-base prompt. <br>

Explored Modules should follow the following guidelines: <br>

1. Installed in /extbin/[MODULES-TYPE] specific folder (e.g generators will be installed in /extbin/generators)
2. Include metadata file: modules.json
   The modules.json for generators should include the following parameters:

```javascript
{
  templates: [
      "name": string, //This name will be displayed in the yeoman-base prompt as part of templates option list. (e.g "SAPUI5 Application")
      "path": string, //Relative path to the template's package. (e.g. "/generators/")
      "features" : [{name : string, values :string[]}], // an array of key-value objects. declares the generator supported features in which this generator can be filtered (e.g [{name:"protocol" : value : ["odataV4"]}])
    }
  ]
}
```

The modules.json for service-provider should include the following parameters:

```javascript
{
  "serviceProviders":[
    {
      "name": string,//This name will be displayed in the yeoman-base prompt as part of service providers option list. (e.g "Steam Punk")
      "path": string, //Path to the service providers package. (e.g. "/extbin/serviceProviders/OdataProviders/SteamPunk-service-provider",
      "features" : [{name : string, values :string[]}], //an array of key-value objects. declares the service-provider supported features in which this module can be filtered (e.g [{name:"protocol" : value : ["odataV4"]}])
      "entryPoint" :{ //The main entry point to trigger the specific service provider logic
         "class" : "ServiceProviderExample ", //The main object
         "method" : "dummyServiceProviderPrompt" //The main method
      }
   }
  ]
}
```

**promptExploredModules** <br>
