dotprovider example
A custom dot provider (the repository pattern): a small Go type exposes
hardcoded in-memory data to templates as {{.Shop}}. templates/index.html
ranges over {{.Shop.Products}} and looks one up with {{.Shop.Product 2}}.
Run it:
mise run example-dotprovider
Then open http://localhost:9006/.
Writing a dot provider
Implement xtemplate.Provider (FieldName() string, Prototype() any,
Value(http.ResponseWriter, *http.Request) (any, error)), then register a
factory via xtemplate.WithProvider(func() xtemplate.Provider { return p })
passed to app.Main. Each Instance / Reload invokes the factory for a fresh
provider value. FieldName is the dot field name (Shop here); Prototype is
a typed zero for reflection; Value returns the value assigned to {{.Shop}}
for each request. Init is optional (save the instance context there if
request-time code needs it). See main.go.

Overview ¶
Custom dot provider example: the "repository pattern". A custom provider exposes hardcoded in-memory data to templates as {{.Shop}}, which can range over products and look one up by id.
To write a dot provider: implement xtemplate.Provider (FieldName, Prototype, Value), then register a factory with xtemplate.WithProvider passed to app.Main. FieldName is the dot field name; Prototype is a typed zero value for reflection; Value returns the value assigned to that field for each request. Init is optional (Initializer).
