ServiceWorker task scheduler

This is a proof of concept of a task scheduler inside a ServiceWorker.


The Service Worker has a non-blocking infinite loop (using setInterval) constantly checking in a task queue Set whether the due date arrives and runs the task.

When a user sends a task message to the service worker:

  1. It adds the task to a list of pending tasks
  2. Then the worker compares the scheduled date of the task against a Date object with the actual date
  3. If dates match, the task is run and a notification is shown
  4. The task is added to a Set of done tasks (to keep track of already done tasks)


$ git clone
$ cd sw-task-scheduler
$ npm install
$ npm start
