(Part 2) Build a Simple Chat Character Gallery: Project Setup
James Tedy6 min read
📚 Tutorial Series: Build a Chat Character Gallery
Project Setup - You’re here
Part 2: Project Setup
In the previous post, we talked about the concept behind the Chat Character Gallery — what it is, what features it includes, and what you’ll build by the end of this tutorial series.
Now, let’s roll up our sleeves and dive into the tech stack and project setup. In this part, we’ll go over the tools we’ll be using and set up the foundation of our app so we can start building in the next steps.
Here’s the tools that we will use to build our project:
Tech Stack:
Next.js
TypeScript
TailwindCSS
Axios
API:
- Companion AI - An API designed to generate natural, human-like responses for chatbots
🚀 Step 1: Initialize Your Project
npx create-next-app@latest chat-character-gallery
cd chat-character-gallery
Choose Yes for everything except for Turbopack and import alias
Add tailwind.config.js to your directory and add this file
/** @type {import('tailwindcss').Config} */
const config = {

📦 Step 2: Install other dependencies
pnpm add axios @tanstack/react-query clsx tailwind-merge
axios - Promise based HTTP client for browsers
@tanstack/react-query - Powerful asynchronous state management for TS/JS or React
clsx and tailwind-merge - Packages to be used to merge TailwindCSS
🎨 Step 3: Set up ESLint
Refer to this documentation for more about ESLint in NextJs: NextJs - ESLint
Install these devDependencies:
pnpm add -D typescript-eslint @eslint/js globals eslint-plugin-react
🧪 Step 4: Update next.config.ts and tsconfig.json
These are just to make sure you’re using the same config as what I’m using. Feel free to edit these to your preference later:
Update next.config.ts
import type { NextConfig } from "next";
const nextConfig: NextConfig = {
reactStrictMode: true,
transpilePackages: [],
experimental: {
typedRoutes: true,
},
devIndicators: false,
};
export default nextConfig;
Update tsconfig.json
{
"compilerOptions": {
"target": "es2020",
"lib": ["dom", "dom.iterable", "esnext"],
"allowJs": true,
"skipLibCheck": true,
"strict": true,
"forceConsistentCasingInFileNames": true,
"noEmit": true,
"esModuleInterop": true,
"module": "esnext",
"moduleResolution": "bundler",
"resolveJsonModule": true,
"isolatedModules": true,
"jsx": "preserve",
"incremental": true,
"plugins": [{ "name": "next" }],
"baseUrl": ".",
"paths": {
"@/modules/*": ["src/modules/*"],
"@/components/*": ["src/components/*"],
"@/*": ["src/*"]
}
},
"include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
"exclude": ["node_modules"]
}
🤖 Step 5: Setup your .env
Here’s the example of .env file. Please make sure to not push .env to your Git.
NEXT_PUBLIC_API_URL=YOUR_API_URL
NEXT_PUBLIC_X_RAPID_API_KEY=YOUR_X_RAPID_API_KEY
NEXT_PUBLIC_X_RAPID_API_HOST=YOUR_X_RAPID_API_HOST
NEXT_PUBLIC_API_KEY=YOUR_API_KEY
Next would be to Sign up to the API that we will be using for this project, which is Companion AI API.
Please follow their tutorial to get your API Key.
