In this episode, we kick things off by setting up a fresh Laravel project with Livewire and prepare it to interact with OpenAI using the official PHP client. We start by signing up for an OpenAI account and creating a new project to grab our API key. Don't forget: it's important to copy that key right away because OpenAI will only show it once!
Next up, we set up our Laravel environment to securely store this secret key in the .env
file. To keep things nicely organized, we also create a new configuration file (config/openai.php
) so we can easily access the API key across our project.
With the prep work done, we use Composer to pull in the OpenAI PHP client library. Then, we jump over to our AppServiceProvider
and bind the OpenAI client as a singleton in Laravel's service container, making it super easy to inject wherever we need it.
We wrap up by making a test API call right from our web routes. We send a simple example chat request to the GPT-4 model, giving it a friendly prompt and checking to see that we're getting good responses back from OpenAI. This ensures everything is working before we move on. In the next episodes, we'll shift our focus to building out the actual chat interface and handling responses more efficiently.
