You are working on a codebase for a cloud infrastructure management tool, and your task is to implement the necessary types to support alias management. An alias is a reference name that can be given to a resource ID or a specific configuration. 

You are provided with a code snippet that shows two type definitions: `AliasName` and `Properties`. 

The `AliasName` type represents an alias name and is defined as `pulumi.StringPtrInput`. The `pulumi` package provides utilities and types for working with infrastructure-as-code.

The `Properties` type represents the properties of a put alias request. It is defined as `PutAliasRequestPropertiesPtrInput`.

Your task is to complete the implementation of the `AliasName` and `Properties` types based on the given definitions.

Implement the `AliasName` type as a wrapper around a `string` type, allowing it to be nullable.

Implement the `Properties` type as a wrapper around a `PutAliasRequestProperties` type, allowing it to be nullable.

Write the necessary code to correctly implement the types and complete any missing parts. Make sure to follow best practices and provide a correct solution.

Sure, I can help with that. Here's a TypeScript implementation based on your provided code snippets:

```typescript
import * as pulumi from '@pulumi/pulumi';

interface AliasName {
  [key: string]: string | undefined;
}

/**
 * A alias name contain a reference to a resource or configuration.
 */
export class AliasName extends pulumi.CustomType {
  private _value: AliasName;

  constructor(value: pulumi.Input<AliasName>) {
    super('aliasname', value, {
      input: true,
      output: false,
    });

    this._value = {};

    // Handle input value to deep watched property of this instance.
    const unwrapped = pulumi.value(value);
    if (unwrapped !== undefined) {
      for (const key of Object.keys(unwrapped)) {
        this._value[key] = unwrappers[key];
      }
    }

    // Handle update function.
    this.update = (newValue, oldValue, oldSnapshot) => {
      if (oldSnapshot) {
        // Compare new value with deep-merged old value and snapshot.
        for (const key of Object.keys(newValue)) {
          if (oldValue[key] !== newValue[key]) {
            this._value[key] = newValue[key];
          }
        }

        // Merge new `snapshot` with old `snapshot`.
        for (const key of Object.keys(newSnapshot)) {
          if (oldSnapshot[key] !== newSnapshot[key]) {
            this._value[key] = newSnapshot[key];
          }
        }
      } else {
        for (const key of Object.keys(newValue)) {
          this._value[key] = newValue[key];
        }
      }
    };

    return this._value;
  }

  get value(): AliasName {
    return this._value;
  }
}

interface PutAliasRequestProperties {
  id: pulumi.Input<string>;
  name: pulumi.Input<AliasName>;
}

/**
 * The request properties for operations on Aliases.
 */
export class PutAliasRequestProperties extends pulumi.CustomType {
  constructor(value: pulumi.Input<PutAliasRequestProperties>) {
    super('putaliasrequestproperties', value, {
      input: true,
      output: true,
    });

    this._value = {};

    // Handle input value to deep watched property of this instance.
    const unwrapped = pulumi.value(value);
    if (unwrapped !== undefined) {
      (unwrapped.id as string) && (this._value.id = unwrapped.id);
      (unwrapped.name as AliasName) && (this._value.name = new AliasName(unwrapped.name));
    }

    // Handle update function.
    this.update = (newValue, oldValue, oldSnapshot) => {
      if (oldSnapshot) {
        // Compare new value with deep-merged old value and snapshot.
        if (oldSnapshot.id !== pulumi.value(newValue).id) {
          this._value.id = newValue.id;
        }

        if (
          pulumi.value(newValue).name &&
          oldSnapshot.name !== pulumi.value(newValue).name
        ) {
          this._value.name = new AliasName(newValue.name);
        }
      } else {
        // Assign new value to object.
        this._value.id = pulumi.value(newValue).id;
        this._value.name = new AliasName(newValue.name);
      }
    };

    return this._value;
  }

  get id(): string {
    return this._value.id;
  }

  get name(): AliasName {
    return this._value.name;
  }
}
```

You are working on a codebase for a cloud infrastructure management tool, and your task is to implement the necessary types to support alias management. An alias is a reference name that can be given to a resource ID or a specific configuration.

Sure, I can help you with that. Given that you're using Pulumi, a modern Infrastructure as Code (IaC) tool, I'll provide the solution in TypeScript, one of the languages Pulumi supports.

Here's how you can implement the `AliasName` and `Properties` types:

```typescript
import * as pulumi from "@pulumi/pulumi";

// AliasName type definition
type AliasName = pulumi.Input<string | null>;

// Properties type definition
interface PutAliasRequestProperties {
    // Define the properties for your PutAliasRequest here
    // For example:
    // resourceId: pulumi.Input<string>;
    // configuration: pulumi.Input<string>;
}

type Properties = pulumi.Input<PutAliasRequestProperties | null>;
```

In this code, `AliasName` is defined as a Pulumi input of type string that can also be null. Similarly, `Properties` is defined as a Pulumi input of type `PutAliasRequestProperties` that can also be null.

Please replace the comment in `PutAliasRequestProperties` with the actual properties you need for your use case.
