Create your own ChatGPT App in 1 Minute

Here's what we'll be building in just a minute:

The create-svelte-chatgpt package enables you to effortlessly set up a SvelteKit application integrated with ChatGPT, the powerful language model by OpenAI. This package comes with a pre-built chat interface, saving you time on design and implementation. As a demonstration of what you can achieve with this package, we'll walk through the process of creating a chatbot that impersonates a specific character. Even if you're not familiar with Svelte, you can easily follow along and get started.

Prerequisites

Before we begin, ensure you have the following:

• Node.js installed on your system
• An OpenAI API key (you can obtain one from the OpenAI dashboard)

Step 1: Install the create-svelte-chatgpt package

Execute the following command in your terminal:

npx create-svelte-chatgpt@latest

This command prompts you for a project name, and then generates a new SvelteKit application with ChatGPT preconfigured.

Step 2: Configure your API key and environment

cd into your project directory, create a .env file in the root directory of your new project and add your OpenAI API key. Optionally, you can also provide a Redis URL and password for persistent chat history.

OPENAI_API_KEY=xxx
REDIS_URL=yyy # Optional
REDIS_PASSWORD=zzz # Optional

Step 3: Customize the chatbot character

Navigate to the src/lib/config/index.ts file. You'll find a createConfig() function that returns an object containing various properties related to the chatbot character. To customise the character, modify the following properties:

• nickName: The nickname for your character.
• fullName: The full name of the character.
• receiverImgSrc: The URL or path to the image representing the character.
• senderImgSrc: The URL or path to the image representing the user.
• promptPrefix: A prefix added to user input to guide the AI (e.g., "Act as Elon Musk, ").

For instance, you can alter the configuration to simulate a conversation with Elon Musk:

export function createConfig() {
  return {
    nickName: 'Elon',
    fullName: 'Elon Musk',
    receiverImgSrc: 'https://i.imgur.com/zUAmDNj.png' // This was generated via MidJourney!,
    senderImgSrc: senderImg,
    promptPrefix: 'Answer this as if you were Elon Musk: \n\n'
  };
}

Step 4: Run the application

Start a development server by executing the following command in your terminal:

npm run dev

Now, open your browser and visit http://localhost:5173 to interact with your chatbot character.

Conclusion

The create-svelte-chatgpt package serves as a boilerplate for building chatbot applications with Svelte and ChatGPT. Now that you have a solid foundation in place, you can expand and customise your application to suit your needs. The possibilities are endless, happy coding!
