- Uses typescript decorators to provide metadata for function calling

- Automatically generate function calling JSON schema from decorated typescript functions

- Automatically call functions based on name and JSON-formatted arguments

- Can be used with OpenAI's Chat Completion API as well as the Assistants API

## Example

```typescript

import { gptFunction, gptString, FunctionCallingProvider } from 'function-gpt';

// Define the type of the input parameter for functions above.

class BrowseParams {

  // Decorate each field with @gptObjectField to provide necessary metadata.

  @gptString('url of the web page to browse')

  public url!: string;

}

// Create your own class that extends FunctionCallingProvider.

class BrowseProvider extends FunctionCallingProvider {

  // Define functions that you want to provide to OpenAI for function calling.

  // Decorate each function with @gptFunction to provide necessary metadata.

  // The function should accept a single parameter that is a typed object.

  @gptFunction('make http request to a url and return its html content', BrowseParams)

  async browse(params: BrowseParams) {

    const response = await fetch(params.url);

    return await response.text();

  }

}

const provider = new BrowseProvider();

const schema = await provider.getSchema();

const result = await provider.handleFunctionCall(

  'browse',

  JSON.stringify({ url: 'https://www.google.com' }),

);

```
