Развёртывание в Vercel и Netlify

You've built an amazing Next.js application locally. But how do you share it with the world?

Deployment is the process of publishing your application so users can access it online. It makes your project live on the internet!

• Accessibility: Anyone can visit your site.
• Scalability: Handle more users as your app grows.
• Reliability: Keep your app running smoothly 24/7.

For Next.js applications, serverless platforms are the go-to choice. They handle all the server infrastructure for you, so you can focus on coding.

Two of the most popular and developer-friendly platforms are Vercel and Netlify. Both offer seamless integration with Next.js and Git repositories.

• No server management needed.
• Automatic scaling.
• Built-in CDN for speed.

Vercel is created by the team behind Next.js, making it the most optimized platform for Next.js applications.

It provides an effortless deployment experience with features like instant static deployments, serverless functions, and automatic scaling.

• Deep Next.js integration.
• Fast global CDN.
• Automatic SSL certificates.

You can deploy your Next.js project to Vercel directly from your terminal using the Vercel CLI. First, install it globally:

npm install -g vercel

Then, navigate to your project directory and simply run vercel. It will guide you through the setup, linking to your account and deploying your project.

The most common way to deploy with Vercel is by connecting your Git repository (GitHub, GitLab, Bitbucket). Once connected, Vercel automatically deploys every time you push changes to your main branch.

This enables Continuous Deployment (CD), automating the release process and ensuring your live site is always up-to-date with your code.

Netlify is another powerful serverless platform that supports Next.js projects very well. It offers a similar suite of features including continuous deployment, serverless functions, and a global CDN.

Netlify also provides a user-friendly dashboard and excellent tools for managing your web projects.

• Powerful build system.
• Integrated with Git.
• Serverless functions available.

Similar to Vercel, Netlify has its own CLI tool. To get started, install it globally:

npm install -g netlify-cli

From your project directory, run netlify init to connect your project to Netlify, or netlify deploy to deploy a specific build. Netlify will detect your Next.js setup automatically.

Your Next.js app might use environment variables (e.g., API keys). It's crucial not to hardcode these in your public code.

Both Vercel and Netlify provide secure ways to manage environment variables directly in their dashboards. You add them once, and they're available to your application during the build and runtime phases.

• Securely store sensitive data.
• Different values for different environments (e.g., development, production).

After deployment, your app will have a temporary URL (e.g., your-project.vercel.app). You'll likely want to use your own domain (e.g., www.mycoolapp.com).

Both Vercel and Netlify make it easy to add custom domains through their dashboards. They also automatically provision and renew free SSL certificates (HTTPS) for your domains, ensuring secure connections.

The true power of these platforms comes with Continuous Deployment (CD). Once set up, every time you push code to your connected Git branch (e.g., main), Vercel or Netlify automatically:

1. Pulls your latest code.
2. Builds your Next.js application.
3. Deploys the new version.
4. Invalidates CDN cache.

This workflow saves time and reduces errors, ensuring your live site is always current.

In this lesson, we explored the essentials of deploying your Next.js applications. We learned that platforms like Vercel and Netlify simplify the process by offering serverless infrastructure, continuous deployment, and easy management of domains and environment variables.

You're now equipped to take your Next.js projects from local development to a live, production-ready website!
