const Job = require('runjob')Creating a Job
const myJob = new Job(function () {
console.log('Look mum, I got a job!')
}, 'MyJob')The name (second argument) is optional and is only relevant for the Job.tree() function
Executing a Job
Now
myJob.run.now()In 500 ms
myJob.run.in(500).ms()In 2 seconds
myJob.run.in(2).seconds()In 3 minutes
myJob.run.in(3).minutes()Every 500 ms
myJob.run.every(500).ms()Every 2 seconds
myJob.run.every(2).seconds()Every 3 minutes
myJob.run.every(3).minutes()At a specific Date
myJob.run.at(new Date().getTime() + 3000) // Run at the Date in 3 seconds
myJob.run.at(new Date(new Date().getTime() + 4000)) // Run at the Date in 4 seconds
myJob.run.at(new Date()) // Run nowList all Jobs
Just simply run
Job.tree()Queues
A queue handles jobs successively and fires an event when the queue is empty. Queues also work like they are a job, so you can use something like myQueue.run.in(2).seconds() to handle it at a certain time.
Creating a Queue
const myQueue = new Job.Queue()Adding Jobs to a queue
First you need to create a few jobs. Then you can add them to the queue like this:
myQueue.add(jobOne, jobTwo)
myQueue.add(jobThree)Handling a Queue
myQueue.handle().then(() => {
console.log('Queue finished!')
})Chains
Chains are like queues, but they work simultaneously. This means that if the Chain is handled all jobs are started at the same time.
You can use a Chain exactly like a Queue, but you have to use Job.Chain instead of Job.Queue.
It's also important to know that Chains don't fire an event if they finished, so you can't use myChain.handle().then() and have to use myChain.handle()
