Pomodoro Clock

Built with

html5
css
sass

Overview

I took FreeCodeCamp Front End Development Libraries Projects to improve my front end skills. With this project I used vanilla JavaScript to build a functioning Pomodoro Clock.

Goals

Build a CodePen.io app that is functionally similar to this: https://codepen.io/freeCodeCamp/full/XpKrrW. I decided to make the Pomodoro Clock look like similar to https://pomofocus.io/ .

Lessons Learned

In this project I successfully used JavaScript to make a library.

Process

I followed the freecodecamp user story:

  • User Story #1: I can see an element with id="break-label" that contains a string (e.g. "Break Length").
  • User Story #2: I can see an element with id="session-label" that contains a string (e.g. "Session Length").
  • User Story #3: I can see two clickable elements with corresponding IDs: id="break-decrement" and id="session-decrement".
  • User Story #4: I can see two clickable elements with corresponding IDs: id="break-increment" and id="session-increment".
  • User Story #5: I can see an element with a corresponding id="break-length", which by default (on load) displays a value of 5.
  • User Story #6: I can see an element with a corresponding id="session-length", which by default displays a value of 25.
  • User Story #7: I can see an element with a corresponding id="timer-label", that contains a string indicating a session is initialized (e.g. "Session").
  • User Story #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).
  • User Story #9: I can see a clickable element with a corresponding id="start_stop".
  • User Story #10: I can see a clickable element with a corresponding id="reset".
  • User Story #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 its default state.
  • User Story #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.
  • User Story #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.
  • User Story #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.
  • User Story #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.
  • User Story #16: I should not be able to set a session or break length to <= 0.
  • User Story #17: I should not be able to set a session or break length to > 60.
  • User Story #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.
  • User Story #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).
  • User Story #20: If the timer is running and I click the element with id="start_stop", the countdown should pause.
  • User Story #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.
  • User Story #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.
  • User Story #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.
  • User Story #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.
  • User Story #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.
  • User Story #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".
  • User Story #27: The audio element with id="beep" must be 1 second or longer.
  • User Story #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.
