Usage

// You can find this test script in the src folder
import CharacterAI from 'node-character.ai';

export class Test {
  public static async sendMessage(message: string): Promise<void> {
    const characterAi = new CharacterAI();
    // accessToken is required; keep reading for details.
    await characterAi.authenticate(process.env.CHARACTERAI_TOKEN);

    // you can find your characterId in the URL of a Character's chat page. Keep reading for details.
    const chat = await characterAi.continueOrCreateChat(
      process.env.CHARACTERAI_CHARID,
    );

    // send a message and wait for the response
    const response = await chat.sendAndAwaitResponse({
      message,
      singleReply: true, // if you want just what would show up in the chat, set this to true
    });

    // response can be either an array of possible responses or a single response
    console.log(response);
  }
}

Test.sendMessage('Greetings! What are your plans for today?');
