Customization

Debug

The Slim instance property Slim#Debug can be used to enable or disable debug mode.

Filesystem

The property Slim#Filesystem is used for static file serving, defaulting to the working directory of our program.

s.Filesystem = os.DirFS("/path/to/entry")

The property Slim#Validator can be used to register a validator to perform data validation based on request payload.

func newCustomValidator() slim.Validator {    // ...}s.Validator = newCustomValidator()

Custom Binder

The property Slim#Binder can be used to register custom data binding logic to parse data submitted during requests.

func newCustomBinder() slim.Binder {    // ...}s.Binder = newCustomBinder()

Custom Codec

We can customize codec logic through the following two properties:

• Property Slim#JSONCodec for encoding and decoding JSON data
• Property Slim#XMLCodec for encoding and decoding XML data

func newJSONCodec() slim.Codec {}func newXMLCodec() slim.Codec {}s.JSONCodec = newJSONCodec()s.XMLCodec = newXMLCodec()

The property Slim#Renderer can be used to register a renderer for template rendering.

func newRenderer() slim.Renderer {    // ...}s.Renderer = newRenderer()

Error Handler

The property Slim#ErrorHandler can be used to register a custom HTTP error handler.

s.ErrorHandler = func(c slim.Context, err error) {    //  handling the error    c.JSON(http.StatusInternalServerError, slim.Map{        "message": err.Error(),        "stack": stackFor(err), // for debug    })}
