The Development Adventure: Bringing Feastly.ai to Life
Setting the Stage: The Next.js Development Environment
Crafting the perfect environment for Feastly.ai was a walk in the park, thanks to Next.js' top-notch documentation. Following the official Next.js tutorial, I set up a new project and installed the essential dependencies. My go-to packages included:
- axios: for smooth API calls
- openai: the key to integrating OpenAI's API
- tailwindcss: styling the app with flair
With the foundations laid, I was ready to build Feastly.ai from the ground up.
OpenAI API Integration: The Heartbeat of Feastly.ai
First things first, I created a new OpenAI account and generated a shiny API key. Safely tucked away in a .env file, the key was accessible via the process.env object.
Next, I carved out an API route in the api directory of my Next app to manage the API calls. This route facilitated communication with the OpenAI API, resulting in a JSON object packed with the freshly generated recipe.
Connecting to the OpenAI API was a breeze, thanks to a single function call from the openai package:
return await openai.createCompletion({
model: "text-davinci-003",
prompt: prompt,
temperature: 0.4,
max_tokens: 4096 / 2,
frequency_penalty: 0,
presence_penalty: 0,
stop: ["{}"],
});My API route took on the following form (I've trimmed the error handling code for simplicity's sake):
export async function POST(request: Request) {
const req = (await request.json()) as RequestType;
const recipe = await imagineRecipe(req.ingredients);
return new Response(JSON.stringify(recipe));
}With the OpenAI API snugly integrated, Feastly.ai was ready to dazzle users with its recipe-generating prowess.
A Feast for the Eyes: Crafting the User Interface
With the GPT integration firmly in place, it was time to whip up a delightful user interface. Naturally, I turned to Tailwind CSS, a trusty ally I've come to know and love. While I won't delve too deeply into this part of the process, allow me to give you a glimpse of the ingredient prompt I cooked up for Feastly.ai. Though there's still plenty of work ahead to polish the design and add more features, I'm rather pleased with the outcome thus far.
As of this blog post's publication date, the recipe page sports a minimalistic design with ample room for improvement. Rest assured, I'll be refining it in the coming weeks, and you might just spot an update on this post showcasing the fresh new look.
Navigating the Roadblocks: Challenges and Solutions
Mastering the Art of Recipe Generation
While GPT-3.5 conjures up generally impressive recipes, it can falter when faced with obscure or whimsical ingredients. Some resulting suggestions might be inedible, dangerous, or downright absurd.
