100% Flow Coverage

Proudly built with 100% Flow Coverage and exported .flow.js files so your flow projects will benefit!

We strongly recommend you look over the types in the source. This will give you an idea of how the various pieces of the package work.

Note: There are certain things Flow is not capable of providing type coverage for, such as try/catch blocks. These are not included in our assessment of "100% Coverage".

Example

Simple

/* @flow */

import createTaskHandler from 'task-handler';

const task = createTaskHandler('simple');

task.after(
  'task:one',
  3000,
  (ref, arg: string) => log('task:one execute', arg),
  'foo',
);

// every interval, execute
task.every(
  'task:two',
  3000,
  (ref, arg: string) => log('task:two execute', arg),
  'bar',
);

// immediately execute (nextTick, immediate, timeout priority - first found)
task.defer(
  'task:four',
  (ref, arg: string) => log('task:four execute', arg),
  'qux',
);

// every interval and immediately, execute
task.everyNow(
  'task:three',
  3000,
  (ref, arg: string) => log('task:three execute', arg),
  'baz',
);

// clear all tasks, killing the event queue and completing execution
task.after('complete', 10000, () => {
  log('complete - clearing tasks');
  task.clear();
});
