Collage is build as a plugin library. Each basic feature is defined as a plugin. All default plugins are configured and bootstrapped together.
Each collage plugin needs to call the plugin function. The shape and general structure of a plugin is defined here.
Bootstraps all defined collage-plugins into a collage object (see Collage)
The collage object then contains the functions expose, updateContext, extractContextAsArrangement, extractContextAsFragment and extractFragmentDescription as well as a reservedWords array.
The reservedWords are identifiers, which are reserved for collage and plugins and can not be defined as e.g. direct functions by a micro-frontend (see direct-functions-plugin).
The updateContext function is used by the syntactic sugar functions (see Syntactic Sugar API).
The expose function is the only function which is exported directly to be used in the micro-frontends.
The other functions are for setting up a collage context and performing the handshake between fragment and arrangement.
Module for internal logging
When establishing the connection between a fragment and its arrangement, penpal is not available for communication yet. So we are using the postMessage Api directly for performing a handshake.
