Chapter 1: Getting Started

April 13, 2026 ยท View on GitHub

Welcome to Chapter 1: Getting Started. In this part of Onlook Tutorial: Visual-First AI Coding for Next.js and Tailwind, you will build an intuitive mental model first, then move into concrete implementation details and practical production tradeoffs.

This chapter gets you productive with Onlook through hosted and local entry points.

Learning Goals

  • choose hosted or local startup path
  • initialize a Next.js + Tailwind workflow in Onlook
  • understand first edit and preview loop
  • avoid common setup friction quickly

First-Use Checklist

  1. open or create a Next.js + Tailwind project
  2. run first visual edit in preview canvas
  3. use AI chat for a scoped UI change
  4. verify generated code in source panel
  5. confirm change persists in your repository files

Summary

You now have a working Onlook baseline for visual and prompt-driven iteration.

Source Code Walkthrough

docs/next.config.ts

The next.config module in docs/next.config.ts handles a key part of this chapter's functionality:

/**
 * Run `build` or `dev` with `SKIP_ENV_VALIDATION` to skip env validation. This is especially useful
 * for Docker builds.
 */
import { createMDX } from 'fumadocs-mdx/next';
import { NextConfig } from 'next';
import path from 'node:path';

const withMDX = createMDX();

const nextConfig: NextConfig = {
    reactStrictMode: true,
};

if (process.env.NODE_ENV === 'development') {
    nextConfig.outputFileTracingRoot = path.join(__dirname, '../../..');
}

export default withMDX(nextConfig);

This module is important because it defines how Onlook Tutorial: Visual-First AI Coding for Next.js and Tailwind implements the patterns covered in this chapter.

docs/tsconfig.json

The tsconfig module in docs/tsconfig.json handles a key part of this chapter's functionality:

{
  "compilerOptions": {
    "baseUrl": ".",
    "target": "ESNext",
    "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": "react-jsx",
    "incremental": true,
    "paths": {
      "@/.source": [
        "./.source/index.ts"
      ],
      "@/*": [
        "./src/*"
      ]
    },
    "plugins": [
      {
        "name": "next"
      }
    ]
  },

This module is important because it defines how Onlook Tutorial: Visual-First AI Coding for Next.js and Tailwind implements the patterns covered in this chapter.
