Next.js 部署

到目前为止，我们已经在开发模式下开发并运行了示例 NEXT.JS 应用程序，现在我们将使用以下步骤在本地进行生产部署。

• npm run build − 构建生产就绪、高度优化的部署架构。
• npm run start − 启动服务器。

与开发模式相比，生产就绪构建缺少源映射和热代码重新加载，因为这些功能主要用于调试。

构建前准备

运行以下命令来准备生产就绪构建。

$ npm run build

> nextjs@1.0.0 build /workspace/node/nextjs
> next build

启动 Next.js 服务器

运行以下命令启动服务器

$ npm run start

> nextjs@1.0.0 start /workspace/node/nextjs
> next start

ready - started server on 0.0.0.0:3000, url: http://localhost:3000
info  - Loaded env from /workspace/node/nextjs/.env.local

在浏览器中打开 localhost:3000/api/user ，我们将看到以下输出。
