Pomodoro clock

Not pretty, but the design's functional. The application logic is the fun part, anyway, and it's where my talents are better directed.

I created this app as a requirement for my freeCodeCamp Front End Libraries Certification, using Redux, React, React Redux, Bootstrap, React Bootstrap, react-fontawesome, and the alarm beeping noise used in freeCodeCamp's example. It fulfills the following user stories:

  1. I can see an element with id="break-label" that contains a string (e.g. "Break Length").
  2. I can see an element with id="session-label" that contains a string (e.g. "Session Length").
  3. I can see two clickable elements with corresponding IDs: id="break-decrement" and id="session-decrement".
  4. I can see two clickable elements with corresponding IDs: id="break-increment" and id="session-increment".
  5. I can see an element with a corresponding id="break-length", which by default (on load) displays a value of 5.
  6. I can see an element with a corresponding id="session-length", which by default displays a value of 25.
  7. I can see an element with a corresponding id="timer-label", that contains a string indicating a session is initialized (e.g. "Session").
  8. I can see an element with corresponding id="time-left". NOTE: Paused or running, the value in this field should always be displayed in mm:ss format (i.e. 25:00).
  9. I can see a clickable element with a corresponding id="start_stop".
  10. I can see a clickable element with a corresponding id="reset".
  11. When I click the element with the id of reset, any running timer should be stopped, the value within id="break-length" should return to 5, the value within id="session-length" should return to 25, and the element with id="time-left" should reset to it's default state.
  12. When I click the element with the id of break-decrement, the value within id="break-length" decrements by a value of 1, and I can see the updated value.
  13. When I click the element with the id of break-increment, the value within id="break-length" increments by a value of 1, and I can see the updated value.
  14. When I click the element with the id of session-decrement, the value within id="session-length" decrements by a value of 1, and I can see the updated value.
  15. When I click the element with the id of session-increment, the value within id="session-length" increments by a value of 1, and I can see the updated value.
  16. I should not be able to set a session or break length to <= 0.
  17. I should not be able to set a session or break length to > 60.
  18. When I first click the element with id="start_stop", the timer should begin running from the value currently displayed in id="session-length", even if the value has been incremented or decremented from the original value of 25.
  19. If the timer is running, the element with the id of time-left should display the remaining time in mm:ss format (decrementing by a value of 1 and updating the display every 1000ms).
  20. If the timer is running and I click the element with id="start_stop", the countdown should pause.
  21. If the timer is paused and I click the element with id="start_stop", the countdown should resume running from the point at which it was paused.
  22. When a session countdown reaches zero (NOTE: timer MUST reach 00:00), and a new countdown begins, the element with the id of timer-label should display a string indicating a break has begun.
  23. When a session countdown reaches zero (NOTE: timer MUST reach 00:00), a new break countdown should begin, counting down from the value currently displayed in the id="break-length" element.
  24. When a break countdown reaches zero (NOTE: timer MUST reach 00:00), and a new countdown begins, the element with the id of timer-label should display a string indicating a session has begun.
  25. When a break countdown reaches zero (NOTE: timer MUST reach 00:00), a new session countdown should begin, counting down from the value currently displayed in the id="session-length" element.
  26. When a countdown reaches zero (NOTE: timer MUST reach 00:00), a sound indicating that time is up should play. This should utilize an HTML5 audio tag and have a corresponding id="beep".
  27. The audio element with id="beep" must be 1 second or longer.
  28. The audio element with id of beep must stop playing and be rewound to the beginning when the element with the id of reset is clicked.

I decided to also give it the feature of typeable inputs for the session length settings.
