Introduction
Hey fellow Gophers! 👋
Ever found yourself wrestling with scheduled tasks in your Go backend? You know, those pesky requirements like running daily analytics, cleaning up stale data, or sending scheduled notifications? Well, I've got some good news for you! Today, we're going to explore how to handle all of these elegantly using GoFrame's gcron module.
What We'll Cover
- Setting up gcron in your project
- Creating various types of scheduled tasks
- Handling failures gracefully
- Best practices and pro tips
Why GoFrame's gcron?
While Go's native time package is powerful, GoFrame's gcron module provides a more developer-friendly approach. It offers:
- Cron-style scheduling
- Configuration file support
- Built-in error handling
- Easy integration with GoFrame's ecosystem
Let's dive in! 🏊♂️
Getting Started
First, let's add gcron to your project:
go get github.com/gogf/gf/v2/os/gcron
Your First Scheduled Task
Here's a simple example to get you started:
package main
import (
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gcron"
"time"
)
func main() {
ctx := gctx.New()
// Run every hour on the half hour
gcron.Add(ctx, "0 30 * * * *", func(ctx context.Context) {
g.Log().Info(ctx, "Time for a coffee break! ☕")
})
g.Log().Info(ctx, "Cron is up and running!")
select {}
}
Pretty neat, right? Let's break down what's happening here.
Understanding Cron Expressions
The cron expression (0 30 * * * *) might look like a cryptic message, but it's actually quite simple:
┌──────── Second (0-59)
│ ┌────── Minute (0-59)
│ │ ┌──── Hour (0-23)
│ │ │ ┌── Day of Month (1-31)
│ │ │ │ ┌ Month (1-12)
│ │ │ │ │ ┌─ Day of Week (0-6)
│ │ │ │ │ │
0 30 * * * *
Pro tip: You can also use these handy shortcuts:
-
@hourly- Run once every hour -
@daily- Run once every day -
@weekly- Run once every week -
@every 1h30m- Run every hour and 30 minutes
Configuration-Based Tasks
Here's something cool: you can define your tasks in a YAML config file:
cron:
cron.job:
- name: "daily-cleanup"
spec: "@daily"
command: "cleanupCommand"
- name: "health-check"
spec: "@every 5m"
command: "healthCheckCommand"
Handling Failures Like a Pro
Nobody likes when things go wrong, but we should be prepared. Here's how to make your scheduled tasks more robust:
gcron.Add(ctx, "@hourly", func(ctx context.Context) {
defer func() {
if err := recover(); err != nil {
// Log the error
g.Log().Errorf("Oops! Something went wrong: %v", err)
// Send alerts (Slack, email, etc.)
sendAlertNotification(err)
// You might want to retry the task
retryTask()
}
}()
// Your task logic here
performImportantTask()
})
Pro Tips 🚀
- Use Context Wisely: Pass context with timeouts for long-running tasks
- Monitor Task Health: Keep track of execution times and success rates
- Log Everything: But be smart about what and how you log
- Plan for Failure: Always have a fallback plan
Real-World Example: Daily Analytics Task
Here's a more complete example that puts it all together:
func setupAnalyticsTask(ctx context.Context) error {
return gcron.Add(ctx, "@daily", func(ctx context.Context) {
// Add timeout context
ctx, cancel := context.WithTimeout(ctx, 30*time.Minute)
defer cancel()
// Add recovery
defer handlePanic()
// Add metrics
startTime := time.Now()
defer trackTaskDuration("daily-analytics", startTime)
// Actual task logic
if err := runDailyAnalytics(ctx); err != nil {
g.Log().Errorf(ctx, "Analytics failed: %v", err)
notifyTeam(err)
return
}
g.Log().Info(ctx, "Daily analytics completed successfully!")
})
}
Conclusion
GoFrame's gcron module makes scheduled tasks a breeze to implement and maintain. Remember:
- Start simple and add complexity as needed
- Always handle errors gracefully
- Monitor and log appropriately
- Test your scheduled tasks thoroughly
