public

Next.js 可以在根目录中名为 public 的文件夹下提供静态文件，例如图片。然后，你的代码可以从基本 URL (/) 开始引用 public 内的文件。

¥Next.js can serve static files, like images, under a folder called public in the root directory. Files inside public can then be referenced by your code starting from the base URL (/).

例如，访问 /avatars/me.png 路径可以查看文件 public/avatars/me.png。显示该图片的代码可能如下所示：

¥For example, the file public/avatars/me.png can be viewed by visiting the /avatars/me.png path. The code to display that image might look like:

缓存

¥Caching

Next.js 无法安全地将资源缓存在 public 文件夹中，因为它们可能会发生变化。应用的默认缓存标头是：

¥Next.js cannot safely cache assets in the public folder because they may change. The default caching headers applied are:

机器人、网站图标等

¥Robots, Favicons, and others

该文件夹也适用于 robots.txt、favicon.ico、Google Site Verification 以及任何其他静态文件（包括 .html）。但请确保静态文件不要与 pages/ 目录中的文件同名，因为这会导致错误。阅读更多。

¥The folder is also useful for robots.txt, favicon.ico, Google Site Verification, and any other static files (including .html). But make sure to not have a static file with the same name as a file in the pages/ directory, as this will result in an error. Read more.
