OpenAI API starter kit for Deno

A bare-bones starter for Deno. This doesn't assume whether you're building a CLI or API, it's just a way to get you started interfacing with OpenAPI.

Getting Started

If you haven't installed Deno yet, follow the instructions here (make sure you follow the Setting up your environment section too).

Once you've got that up and running (make sure you follow the Setting up your environment section too), clone this repo.

Head to https://platform.openai.com/account/api-keys to add an API key. Clone this repo, copy the .env.example file to .env:

git clone https://github.com/andyjessop/deno-openapi.git
cd deno-openapi
cp .env.example .env

Then add your API key to the OPENAI_API_KEY= variable.

OPENAI_API_KEY=your_key_here

Now you can run the app:

deno task start

You should see something like this logged out to the console:

{
  id: "cmpl-6uoXafOpP0Iu54UshgZPyMwOFtXjE",
  object: "text_completion",
  created: 1678998666,
  model: "text-davinci-003",
  choices: [
    {
      text: "\n\nSunny day, so bright\nA gentle breeze, so light\nA perfect summer day",
      index: 0,
      logprobs: null,
      finish_reason: "stop"
    }
  ],
  usage: { prompt_tokens: 8, completion_tokens: 20, total_tokens: 28 }
}

Note that you can use a few command line arguments to modify the completion settings. E.g.:

deno task start --prompt "Write a typescript function to pipe functions" --model "code-davinci-002" --maxTokens 200

Compiling to an executable

There is a task already set-up to compile to a binary format. Just run:

deno task compile

This will create a dist/main.exe which you can then run with ./dist/main.exe. (See the deno.json file for configuration).
