Your Assignment

Unlocking Achievements You need to write the code that listens for user events and unlocks the relevant achievement.

For example;

• When a user writes a comment for the first time they unlock the “First Comment Written” achievement.
• When a user has already unlocked the “First Lesson Watched” achievement by watching a single video and then watches another four videos they unlock the “5 Lessons Watched” achievement.

AchievementUnlocked Event

When an achievement is unlocked an AchievementUnlocked event must be fired with a payload of; achievement_name (string) user (User Model) BadgeUnlocked Event When a user unlocks enough achievement to earn a new badge a BadgeUnlocked event must be fired with a payload of; badge_name (string) user (User Model)

Achievements Endpoint

There is an endpoint users/{user}/achievements that can be found in the ‘web’ routes file, this must return the following;

unlocked_achievements (string[ ]) An array of the user’s unlocked achievements by name

next_available_achievements (string[ ]) An array of the next achievements the user can unlock by name. Note: Only the next available achievement should be returned for each group of achievements. Example: If the user has unlocked the “5 Lessons Watched” and “First Comment Written” achievements only the “10 Lessons Watched” and “3 Comments Written“ achievements should be returned.

current_badge (string) The name of the user’s current badge.

next_badge (string) The name of the next badge the user can earn.

remaining_to_unlock_next_badge (int) The number of additional achievements the user must unlock to earn the next badge. Example: If a user has unlocked 5 achievements they must unlock an additional 3 achievements to earn the “Advanced” badge.

Additional Information Installation

1. A laravel app with the skeleton project is attached
2. From the root directory run composer install
3. You must have a MySql database running locally
4. Update the database details in ‘.env’ to match your local setup
5. Run php artisan migrate to setup the database tables The project is a standard Laravel 8 application, additional installation documentation can be found at https://laravel.com/docs/8.x/installation User Events The course portal fires events when a user carries out specific actions: LessonWatched Fired when a user watches a lesson. CommentWritten Fired when a user writes a comment. These already exist in the codebase and can be found in app/Events. Your task is not to implement the logic that fires these events, you can work on the assumption that another part of the system will be responsible for this. Your assignment is to just listen for these events and ensure the correct achievements & badges are unlocked as outlined in the previous section of this document. User Model The following relationships are available on the user model; watched This will return an eloquent relationship for lessons watched by a user. comments This will return an eloquent relationship for comments written by a user.
