https://www.youtube.com/watch?v=gUgRD0sRoCU&embedable=true If you’re anything like me, you’ve noticed the massive boom in technology. It promises to disrupt not just software engineering but every industry. AI THEY’RE COMING FOR US!!! Just kidding ;P I’ve been bettering my understanding of what these tools are and how they work, and I decided to create a tutorial series for web developers to learn how to incorporate AI technology into web apps. In this series, we’ll learn how to integrate ‘s AI services into an application built with , a JavaScript framework focused on the concept of (this will be relevant to understand later). OpenAI Qwik resumability Here’s what the series outline looks like: Intro & Setup Your First AI Prompt Streaming Responses How Does AI Work Prompt Engineering AI-Generated Images Security & Reliability Deploying We’ll get into the specifics of OpenAI and Qwik where it makes sense, but I will mostly focus on general-purpose knowledge, tooling, and implementations that should apply to whatever framework or toolchain you are using. We’ll be working as closely to fundamentals as we can, and I’ll point out which parts are unique to this app. Here’s a little sneak preview. I thought it would be cool to build an app that takes two opponents and uses AI to determine who would win in a hypothetical fight. It provides some explanation and the option to create an AI-generated image. Sometimes, the results come out a little wonky, but that’s what makes it fun. I hope you’re excited to get started because, in this first post, we are mostly going to work on… Boilerplate 😒 Prerequisites Before we start building anything, we have to cover a couple of prerequisites. Qwik is a JavaScript framework, so we will have to have (and NPM) installed. You can download the most recent version, but anything above version v16.8 should work. I’ll be using version 20. Node.js Next, we’ll also need an to have access to their . OpenAI account API At the end of the series, we will deploy our applications to a VPS (Virtual Private Server). The steps we follow should be the same regardless of what provider you choose. I’ll be using Akamai’s cloud computing services (formerly Linode). New users can go to and get $100 in free credits to get started with Akamai. linode.com/austingil Setting Up the Qwik App Assuming we have the prerequisites out of the way, we can open a command line terminal and run the command: . This will run the Qwik CLI that will help us bootstrap our application. npm create qwik@latest It will ask you a series of configuration questions and then generate the project for you. Here’s what my answers looked like: If everything worked, open up the project and start exploring. Inside the project folder, you’ll notice some important files and folders: : contains all application business logic. /src : contains reusable components to build our app with. /src/components : responsible for Qwik’s file-based routing. Each folder represents a route (can be a page or API endpoint). To make a page, drop a file in the route’s folder. /src/routes index.{jsx|tsx} : this file exports the root component responsible for generating the HTML document root. /src/root.tsx Start Development Qwik uses as a bundler, which is convenient because Vite has a built-in development server. It supports running our application locally and updating the browser when files changes. Vite To start the development server, we can open our project in a terminal and execute the command . With the dev server running, you can open the browser and head to and you should see a very basic app. npm run dev http://localhost:5173 Any time we make changes to our app, we should see those changes reflected almost immediately in the browser. Add Styling This project won’t focus too much on styling, so this section is totally optional if you want to do your own thing. To keep things simple, I’ll use . Tailwind The Qwik CLI makes it easy to add the necessary changes by executing the terminal command, . This will prompt you with several available Qwik plugins to choose from. npm run qwik add You can use your arrow keys to move down to the Tailwind plugin and press Enter. Then it will show you the changes it will make to your codebase and ask for confirmation. As long as it looks good, you can hit Enter once again. For my projects, I also like to have a consistent theme, so I keep a file in my to copy and paste styles from. Obviously, if you want your own theme, you can ignore this step, but if you want your project to look as amazing as mine, copy the styles from into the file. You can replace the old styles but leave the Tailwind directives in place. GitHub this file on GitHub /src/global.css Prepare Homepage The last thing we’ll do today to get the project to a good starting point is make some changes to the homepage. This means making changes to . /src/routes/index.tsx By default, this file starts out with some very basic text and an example for modifying the HTML by exporting a variable. The changes I want to make include: <head> head Removing the export. head Removing all text except the . Feel free to add your own page title text. <h1> Adding some Tailwind classes to center the content and make the larger. <h1> Wrapping the content with a tag to make it more semantic. <main> Adding Tailwind classes to the tag to add some padding and center the contents. <main> These are all minor changes that aren’t strictly necessary, but I think they will provide a nice starting point for building out our app in the next post. Here’s what the file looks like after my changes. import { component$ } from "@builder.io/qwik";

export default component$(() => {
  return (
    <main class="max-w-4xl mx-auto p-4">
      <h1 class="text-6xl">Hi 👋</h1>
    </main>
  );
}); And in the browser, it looks like this: Conclusion That’s all we’ll cover today. Again, this post was mostly focused on getting the boilerplate stuff out of the way so that the next post can be dedicated to integrating OpenAI’s API into our project. With that in mind, I encourage you to take a moment to think about some AI app ideas that you might want to build. There will be a lot of flexibility for you to put your own spin on things. I’m excited to see what you come up with, and if you would like to explore the code in more detail, I’ll post it on my GitHub account at . github.com/austingil/versus Thank you so much for reading.
