Go HTTP middleware for the Leaflet.GeotagPhoto plugin.
Important
Documentation is incomplete.
Example
$> go run -mod vendor cmd/example/main.go

An abbreviated code example
This is an abbreviated example of code to demonstrate appending Leaflet.GeotagPhoto related handlers to an http.ServeMux instance and updating a user-defined http.Handler to append Leaflet.GeotagPhoto Javascript and CSS links to its output.
Error handling has been removed for the sake of brevity.
import (
"github.com/sfomuseum/go-http-leaflet-geotag"
"net/http"
)
func main() {
// code...
geotag_opts := geotag.DefaultLeafletGeotagOptions()
mux := http.NewServeMux()
geotag.AppendAssetHandlers(mux)
camera_handler, _ := PageHandler(t, "camera")
camera_handler = geotag.AppendResourcesHandler(camera_handler, geotag_opts)
mux.Handle("/camera/", camera_handler)
// code...
}
For a complete example please consult cmd/example/main.go. The (Javascript) code for the web application itself is contained in the HTML files in the templates/html directory.

Functions ¶
func AppendAssetHandlers ¶
func AppendResourcesHandler ¶
func AppendResourcesHandler(next http.Handler, opts *LeafletGeotagOptions) http.Handler
func Asset ¶
Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetDir ¶
AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:
data/
foo.txt
img/
a.png
b.png
then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.
func AssetInfo ¶
AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetsHandler ¶
func MustAsset ¶
MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.
func RestoreAsset ¶
RestoreAsset restores an asset under the given directory
func RestoreAssets ¶
RestoreAssets restores an asset under the given directory recursively
Types ¶
type LeafletGeotagOptions ¶
func DefaultLeafletGeotagOptions ¶
func DefaultLeafletGeotagOptions() *LeafletGeotagOptions
