Usage Examples

Check if Resource is Supported

import { ResourceMapper } from './terraform/ResourceMapper.js';

const isSupported = ResourceMapper.isSupported('azurerm_linux_virtual_machine');
// true

const notSupported = ResourceMapper.isSupported('azurerm_redis_cache');
// false

Get All Supported Types

const supportedTypes = ResourceMapper.getSupportedTypes();
// [
//   'azurerm_linux_virtual_machine',
//   'azurerm_windows_virtual_machine',
//   ...
// ]

Map Terraform to Azure Filter

const config = {
  size: 'Standard_D2s_v3',
  location: 'eastus'
};

const result = ResourceMapper.mapToAzureFilter('azurerm_linux_virtual_machine', config);
// {
//   filter: {
//     serviceName: 'Virtual Machines',
//     armRegionName: 'eastus',
//     armSkuName: 'Standard_D2s_v3',
//     unitOfMeasure: '1 Hour',
//     productName: 'Linux'
//   },
//   quantity: 1
// }
