Hydra AI

A framework for generating React components on-the-fly using AI. Register your components, and let Hydra choose when to show them in your App.

notes:

This package is a work-in-progress. Note the following issues:

• expects to be used in a NextJS project
• components that have function props do not work.

Getting started

• Install the package

npm i hydra-ai

2 Set your OpenAI API key environment variable

In a file called .env.local, add:

OPENAI_API_KEY=<your openai api key>

This will be used by the HydraBackend class server-side and is used to make requests to OpenAI.

• Initialize HydraClient and register components

Somewhere in your app, create a new instance of HydraClient.

Then to create a list of components that the AI can choose from, call registerComponent(name, component, propsDefinition, getComponentContext) with each, where:

• name is a unique name for the component
• component is the actual component
• props is an object that describes each available prop of the component.
• getComponentContext is an optional prop that takes a function which Hydra will use to pre-fetch any data Hydra should know about when hydrating this component. For example, if I am registering a "ToDoList" component, I might pass a function that fetches and returns my list of todo items, so Hydra can show real data.

//hydra-client.ts

import { HydraClient } from "hydra-ai";
import CurrentWeather from "./components/current-weather";
import RainChart from "./components/rain-chart";
import WeatherTimeChart from "./components/weather-timechart";
import WindTimeChart from "./components/wind-timechart";

const hydra = new HydraClient();

hydra.registerComponent("CurrentWeather", CurrentWeather, {
  temperatureFahrenheit: "number",
  description: "string",
  weather: '"rain" | "sun" | "cloud" | "snow" | "clear"',
});

hydra.registerComponent("RainChart", RainChart, {
  data: "Array<{ hourOrDay: string; rainChancePercent: number }>",
});

hydra.registerComponent(
  "TodoList",
  TodoList,
  {
    todoItems: "{id: string; title: string; isDone: boolean}[]",
  },
  getTodoItems
);

export default hydra;

• Generate components

const component = await hydra.generateComponent(message);

You will likely want to have a state variable to hold the generated component. Here's a full example page (using NextJS) that uses Hydra, assuming the hydra-client.ts file shown above is created:

"use client";

import { ReactElement, useEffect, useState } from "react";
import hydra from "./hydra-client";

export default function Home() {
  const [dynamicComponent, setDynamicComponent] = useState<ReactElement | null>(
    null
  );

  const fetchComponent = async (message: string) => {
    const component = await hydra.generateComponent(message);
    setDynamicComponent(component);
  };

  useEffect(() => {
    fetchComponent("please show me a weather forecast");
  }, []);

  return (
    <main className="flex min-h-screen flex-col items-center justify-center">
      {dynamicComponent}
    </main>
  );
}
