Rerouted (cache, verified). The original is gone. This copy comes from a Lamdera package cache made before it went. The Lamdera package server serves a copy recovered from a Lamdera package cache from 2021-02-13.
What we checked: Rebuilt from the unpacked sources in a Lamdera package cache (5 copies agree), which Elm only writes after the published SHA-1 checked out; elm.json is byte-identical to package.elm-lang.org's; the exposed modules match docs.json; the zip is our own, so its SHA-1 is not the published one.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.

The ClientProgram module is the Elm code that backs the client-side JS helper library in the iframe-coordinator library. It message handles message validation and delivery to and from clients. This module is not currently designed for stand-alone use. You should instead use the client library defined in iframe-coordinator to create seamless iframe applications
Create a program to handle client messages. Takes an record of ports to send and receive messages on. Communication with the parent application and the local client code are handled through four ports, an input and output pair for the client application and another pair for the host. Port bindings are handled and exposed via the iframe-coordinator library.
