Simple Job Scheduler

This is a simple JavaScript scheduling system written in TypeScript. It is a small wrapper around the setInterval JavaScript function.

Usage

// you should keep only one scheduler instance in your project
// (using either a static reference or using a dependency injection system)
const scheduler = new Scheduler();
// the job will be executed every second
const job = scheduler.schedule('job name', () => console.log('Hello World!'), 1000);
// after some time...
job.cancel();

Why create a library instead of using setInterval?

Have you ever inadvertently launched multiple times the same job? Do you ever wonder if your jobs has successfully been cancelled? Simple Job Scheduler tries to address these issues:

• If the same running job is scheduled twice or more, only the first scheduling time will be taken into account (a job is identified by its name)
• The method scheduler.runningJobs() returns all the running jobs

Release process

• run npm login
• run npm run release <= yarn must not be used
