Public Assets

See the public assets concepts for details.

Because an API may need to serve static assets, every new Strapi project includes by default, a folder named /public. Any file located in this directory is accessible if the request's path doesn't match any other defined route and if it matches a public file name.

Example

An image named company-logo.png in ./public/ is accessible through /company-logo.png URL.

Note: index.html files are served if the request corresponds to a folder name (/pictures url will try to serve public/pictures/index.html file).

Warning bis: The dotfiles are not exposed. It means that every files with the names start by . such as .htaccess or .gitignore are not served.

Refer to the public assets configurations for more informations.
