You've poured your creativity into building an amazing 3D web experience with Three.js. Now, it's time to share it with the world! This section dives into deployment strategies, starting with the most common and accessible: static hosting. We'll explore what it is, why it's ideal for many Three.js projects, and then touch upon other options as your projects grow.
Static hosting is a method where web servers deliver pre-built files directly to the user's browser without any server-side processing. For Three.js projects, this typically means serving your index.html file, your JavaScript bundles (including your Three.js code and any other scripts), and any assets like textures, models, or shaders.
This approach is incredibly efficient because there's no dynamic content generation or database interaction happening on the server for each request. The server just sends the files as they are.
- Performance: Static files are delivered very quickly.
- Cost-Effective: Many static hosting providers offer generous free tiers, making it extremely affordable to get started.
- Scalability: Static hosting services are designed to handle high traffic loads with ease.
- Simplicity: Deployment is straightforward – just upload your built files.
Several platforms make static hosting incredibly easy, often integrating seamlessly with Git repositories.
- GitHub Pages: Free hosting directly from your GitHub repository. Excellent for open-source projects and personal portfolios. You can host from a dedicated
gh-pagesbranch or a/docsfolder. - Netlify: A powerful platform offering continuous deployment from Git, serverless functions, forms, and more. It has a very generous free tier.
- Vercel: Similar to Netlify, Vercel offers a developer-focused platform with excellent performance and a free tier, especially popular for Next.js projects, but works great for any static site.
- Cloudflare Pages: Leverages Cloudflare's global network for fast delivery and offers a robust free tier with powerful features.
Before you can deploy, you'll typically need to 'build' your project. This process takes your development code (which might be split into multiple files, use modern JavaScript features, or include modules) and bundles it into a single or a few optimized JavaScript files, along with your HTML and CSS. Tools like Webpack, Vite, or Rollup are commonly used for this. Your chosen hosting platform will often trigger this build process automatically when you connect your Git repository.
For example, if you're using a build tool like Vite, your build command might look like this:
npm run build
# or
yarn buildThis command usually generates a dist or build folder containing all the files you need to deploy.

D --> E{Build Project}
E --> F[Deploy Static Files to CDN]

When setting up your static hosting provider, you'll usually specify the directory that contains your built assets (e.g., dist or build) and the command to build your project if it's not done locally before pushing.
While static hosting covers many Three.js projects, some experiences might require server-side logic. This could include:
- User Authentication: Managing user logins and sessions.
- Real-time Features: Multiplayer games or collaborative experiences requiring WebSockets.
- Backend Data Storage: Storing user-generated content or complex application states.
- Complex Simulations: Offloading heavy computations to a server.
For these scenarios, you'll need to consider platforms that support dynamic backends. This often involves a combination of static hosting for your front-end Three.js application and a separate backend service.
Options include:
- Serverless Functions: Many static hosting providers (Netlify, Vercel, Cloudflare Pages) offer serverless functions that allow you to run small snippets of backend code in response to HTTP requests or other events. This is a great way to add dynamic features without managing full servers.
- Backend-as-a-Service (BaaS): Platforms like Firebase or AWS Amplify provide pre-built backend services for databases, authentication, hosting, and more.
- Traditional Server Hosting: Deploying your backend application (e.g., Node.js, Python, Ruby) to cloud platforms like Heroku, AWS EC2, Google Cloud Compute Engine, or DigitalOcean. You would then typically serve your Three.js front-end from this server or use a CDN for static assets.
As your Three.js projects evolve, understanding these deployment strategies will ensure your amazing 3D creations reach your audience efficiently and reliably.
