Sails JS hook to add async background agenda.
This project use "agenda" as the job engine
Agenda is a light-weight job scheduling library for Node.js. And it's use mongodb. a
This hook has been tested with sails 0.12.3
npm install sails-hook-jobs
Copy this configurations file and save it to config/jobs.js
/**
* Default jobs configuration
* (sails.config.jobs)
*
* For more information using agenda in your app, check out:
* https://github.com/vbuzzano/sails-hook-jobs
*/
module.exports.jobs = {
// Where are jobs files
"jobsDirectory": "api/jobs",
// agenda configuration.
// for more details about configuration,
// check https://github.com/rschmukler/agenda
"db": {
"address" : "localhost:27017/jobs",
"collection" : "agendaJobs"
},
"name": "process name",
"processEvery": "10 seconds",
"maxConcurrency": 20,
"defaultConcurrency": 5,
"defaultLockLifetime": 10000
};
Simply create a js file (name ending with Job.js, eg: myJob.js) in api/jobs or in the 'jobsDirectory'. (coffee script supported.)
module.exports = function(agenda) {
var job = {
// job name (optional) if not set,
// Job name will be the file name or subfolder.filename (without .js)
//name: 'Foo',
// set true to disabled this job
//disabled: false,
// method can be 'every <interval>', 'schedule <when>' or now
//frequency supports cron strings
frequency: 'every 5 seconds',
// Jobs options
//options: {
// priority: highest: 20, high: 10, default: 0, low: -10, lowest: -20
//priority: 'highest'
//},
// Jobs data
//data: {},
// execute job
run: function(job, done) {
console.log("Foo job executed");
done();
},
};
return job;
}
Once the hook started, you will have a new global object 'Jobs' wich is the instance of Agenda engine.
You can use it like that
Jobs.now('jobname', data)
Jobs.schedule('tommorrow at noon', 'jobname', {})
...
All found jobs with a run function will be defined and all jobs with freq will be sheduled.
