AI summaries are in every application these days. In this lesson, we'll use Google's new Gemini 2.0 AI model and API to generate summaries of text that we can use in any Ruby or Rails app.
Like many AI models, Gemini 2.0 can respond with structured output in a JSON schema that you provide in your request. This is incredibly handy for making integrations that don't have to rely on parsing a blob of text.
We explore the base application and create a turbo stream to append messages and reset the form. We then identify limitations in this approach, and outline necessary improvements for upcoming episodes.
We take care of submitting a message without having to click the form button, and fix an issue we create in doing so around replacing the form. We end with planning our next steps.
We handle scrolling the most recent message into view upon page load along with any new messages that come through while on the page. We also broadcast new messages so everyone stays up to date.
In this episode, we refactor our code to use broadcasts_refreshes to get an extremely simplified version of a chat application.
In this lesson, we dive into the Pagy source code to learn how to best refactor pagination inside of our own code.
