Static Files

Images, JavaScript, CSS, PDF, fonts, etc...

Using Static Middleware​

s := slim.New()
s.Use(slim.Static("./static"))
tip

If we use the function slim.Classic() to initialize, we need to be aware that this method already has built-in static middleware, which uses the ./public folder as the root directory for static service.

For more information about Slim instances, please refer to the Instance section.

Using Slim#Static()​

The instance method Slim#Static(prefix, root string) is used to register routes that provide static services based on path prefixes.

Register folder-based static service route
s := slim.Classic()
s.Static("/static", "assets")

The example above uses the string "/static" as a prefix for routes, responding to requests with any file from the assets directory. For example, when a client requests the file /static/js/main.js, the program will respond with assets/js/main.js.

tip

Additionally, we provide similar methods for both router and route collector to respond to static services.

Using Slim#File()​

The instance method Slim#File is used to register file routes, which can correctly respond with file content.

Example
s := slim.Classic()
// File method defined on Slim instance
s.File("/path", "<PATH/TO/FILE>")

r := s.Router()
// File method defined on router
r.File("/path", "<PATH/TO/FILE>")

r.Group(func(g slim.RouteCollector) {
    // File method defined on route collector
    g.File("/path", "<PATH/TO/FILE>")
})
Homepage route
s.File("/", "public/index.html")

Respond to the homepage using the file we provide "public/index.html".

Favicon
s.File("/favicon.ico", "images/favicon.ico")

Respond to favicon requests using the icon file we provide "images/favicon.ico".

tip

Here, we utilize the context method Context#File(file string) mentioned in the previous Response chapter to correctly respond with files. Additionally, we also provide similar methods for both router and route collector to register file routes.
