Implement reducers with handleActions

Currently most of our reducers are implemented as a big switch statement, which is unwieldy and hard to read. Instead, use the handleActions() helper in redux-actions to implement the reducer as a map of action names to reducer functions.

We should follow the pattern of using the action creator function itself as the map key, allowing us to avoid hard-coding string literals containing the action name.

See the console reducer for an example of the desired implementation.

Testing

Since our goal here is merely to refactor the reducers, not change their behavior, all existing tests should pass after a reducer is refactored.

However, it might make sense to also port the reducer test to Jest after completing the refactor and confirming that the old tests pass with the new reducer implementation (this should be in separate commits).

Reducers to migrate

• clients
• compiledProjects
• console
• currentProject
• errors
• googleClassroom
• index
• projects
• resizableFlex
• ui
• user

Commencez par l’exemple terminé dans src/reducers/console.js, puis localisez les reducers non vérifiés clients, compiledProjects, currentProject, errors, googleClassroom, index, projects et user. Refactorez-les avec redux-actions tout en préservant le comportement, et exécutez tous les tests existants pour confirmer qu’ils passent toujours ; laissez le portage des tests Jest pour une modification distincte.
