pub fn from_base64(value: String) -> String

A convenience method to base64 url decode individual values.

Example

lustre_hash_state.init(fn(key: String, value: String) {

The effect to be returned in your init method. Sets up hashchange event listener and sends messages to update.

pub opaque type Msg {
  HashChange(key: String, value: String)

lustre_hash_state.init(HashChange)
// or
lustre_hash_state.init(fn(key: String, value: String) {
  HashChange(key, value)
})
