go-quartz
A minimalistic and zero-dependency scheduling library for Go.
About
Inspired by the Quartz Java scheduler.
Library building blocks
Scheduler interface
type Scheduler interface {
// Start starts the scheduler.
Start()
// IsStarted determines whether the scheduler has been started.
IsStarted() bool
// ScheduleJob schedules a job using a specified trigger.
ScheduleJob(job Job, trigger Trigger) error
// GetJobKeys returns the keys of all of the scheduled jobs.
GetJobKeys() []int
// GetScheduledJob returns the scheduled job with the specified key.
GetScheduledJob(key int) (*ScheduledJob, error)
// DeleteJob removes the job with the specified key from the Scheduler's execution queue.
DeleteJob(key int) error
// Clear removes all of the scheduled jobs.
Clear()
// Stop shutdowns the scheduler.
Stop()
}
Implemented Schedulers
- StdScheduler
Trigger interface
type Trigger interface {
// NextFireTime returns the next time at which the Trigger is scheduled to fire.
NextFireTime(prev int64) (int64, error)
// Description returns the description of the Trigger.
Description() string
}
Implemented Triggers
- CronTrigger
- SimpleTrigger
- RunOnceTrigger
Job interface. Any type that implements it can be scheduled.
type Job interface {
// Execute is called by a Scheduler when the Trigger associated with this job fires.
Execute()
// Description returns the description of the Job.
Description() string
// Key returns the unique key for the Job.
Key() int
}
Implemented Jobs
- ShellJob
- CurlJob

cronTrigger, _ := quartz.NewCronTrigger("1/5 * * * * *")
shellJob := quartz.NewShellJob("ls -la")
curlJob, _ := quartz.NewCurlJob(http.MethodGet, "http://worldclockapi.com/api/json/est/now", "", nil)
sched.ScheduleJob(shellJob, cronTrigger)
sched.ScheduleJob(curlJob, quartz.NewSimpleTrigger(time.Second*7))
sched.Stop()
