Types

type EchoAssets

type EchoAssets servefiles.Assets

EchoAssets is merely an adapter for servefiles.Assets with the same API and with an additional HandlerFunc method.

func NewAssetHandler

func NewAssetHandler(assetPath string) *EchoAssets

NewAssetHandler creates an Assets value. The parameter is the directory containing the asset files; this can be absolute or relative to the directory in which the server process is started.

This function cleans (i.e. normalises) the asset path.

func NewAssetHandlerFS

func NewAssetHandlerFS(fs afero.Fs) *EchoAssets

NewAssetHandlerFS creates an Assets value for a given filesystem.

func NewAssetHandlerIoFS

func NewAssetHandlerIoFS(fs fs.FS) *EchoAssets

NewAssetHandlerIoFS creates an Assets value for a given filesystem.

func (*EchoAssets) HandlerFunc

func (a *EchoAssets) HandlerFunc(path string) echo.HandlerFunc

HandlerFunc gets the asset handler as an Echo handler. The handler is registered using a catch-all path such as "/files/*". The same match-any pattern can be passed in, in which case it is stripped off the leading part of the URL path seem by the asset handler.

func (*EchoAssets) Register

func (a *EchoAssets) Register(e *echo.Echo, path string)

Register registers the asset handler with an Echo engine using the specified path to handle GET and HEAD requests.

The handler is registered using a catch-all path such as "/files/*". This pattern will be stripped off the leading part of the URL path seem by the asset handler when determining the file to be served.

func (EchoAssets) StripOff

func (a EchoAssets) StripOff(unwantedPrefixSegments int) *EchoAssets

StripOff alters the handler to strip off a specified number of segments from the path before looking for the matching asset. For example, if StripOff(2) has been applied, the requested path "/a/b/c/d/doc.js" would be shortened to "c/d/doc.js".

The returned handler is a new copy of the original one.

func (EchoAssets) WithMaxAge

func (a EchoAssets) WithMaxAge(maxAge time.Duration) *EchoAssets

WithMaxAge alters the handler to set the specified max age on the served assets.

The returned handler is a new copy of the original one.

func (EchoAssets) WithNotFound

func (a EchoAssets) WithNotFound(notFound http.Handler) *EchoAssets

WithNotFound alters the handler so that 404-not found cases are passed to a specified handler. Without this, the default handler is the one provided in the net/http package.

The returned handler is a new copy of the original one.
