methods. + +Commands classes expose static methods, which: +* route to the right Front/Actor's method +* handle backward compatibility +* map to many target's actor if needed + +These classes are instantiated once per descriptor +and may have inner state, emit events, fire callbacks,... + +A transient backward compat need, required by Fission refactorings will be to have some code checking a trait, and either: +* call a single method on a parent process actor (like BreakpointListActor.setBreakpoint) +* otherwise, call a method on each target's scoped actor (like ThreadActor.setBreakpoint, that, for each available target) + +Without such layer, we would have to put such code here and there in the frontend code. +This will be harder to remove later, once we get rid of old pre-fission-refactoring codepaths. + +This layer already exists in some panels, but we are using slightly different names and practices: +* Debugger uses "client" (devtools/client/debugger/src/client/) and "commands" (devtools/client/debugger/src/client/firefox/commands.js) + Debugger's commands already bundle the code to dispatch an action to many target's actor. + They also contain some backward compat code. + Today, we pass around a `client` object via thunkArgs, which is mapped to commands.js, + instead we could pass a debugger command object. +* Network Monitor uses "connector" (devtools/client/netmonitor/src/connector) + Connectors also bundles backward compat and dispatch to many target's actor. + Today, we pass the `connector` to all middlewares from configureStore, + we could instead pass the netmonitor command object. +* Web Console has: + * devtools/client/webconsole/actions/input.js:handleHelperResult(), where we have to put some code, which is a duplicate of Netmonitor Connector, + and could be shared via a netmonitor command class. +* Inspector is probably the panel doing the most dispatch to many target's actor. + Codes using getAllInspectorFronts could all be migrated to an inspector command class: + https://searchfox.org/mozilla-central/search?q=symbol:%23getAllInspectorFronts&redirect=false + and simplify a bit the frontend. + It is also one panel, which still register listener to each target's inspector/walker fronts. + Because inspector isn't using resources. + But this work, registering listeners for each target might be done by such layer and translate the many actor's event into a unified one. + +Last, but not least, this layer may allow us to slowly get rid of protocol.js. +Command classes aren't Fronts, nor are they particularly connected to protocol.js. +If we make it so that all the Frontend code using Fronts uses Commands instead, we might more easily get away from protocol.js. diff
