Step by Step Guide to Building a Google Tasks API Integration in Go

Aug 1, 2024 • 5 minute read

Introduction

Hey there, fellow Go enthusiast! Ready to supercharge your productivity with the Google Tasks API? In this guide, we'll walk through building a slick integration using the google.golang.org/api/tasks/v1 package. Buckle up, because we're about to make task management a breeze!

Prerequisites

Before we dive in, make sure you've got:

Go installed (I know, obvious, right?)
A Google Cloud Project set up (it's easier than it sounds)
OAuth 2.0 credentials (don't worry, we'll touch on this)

Setting up the project

Let's kick things off:

mkdir tasks-api-integration && cd tasks-api-integration
go mod init tasks-api-integration
go get google.golang.org/api/tasks/v1

Authentication

OAuth 2.0 might sound scary, but it's actually pretty straightforward:

import (
    "golang.org/x/oauth2/google"
    "google.golang.org/api/tasks/v1"
)

config := &oauth2.Config{
    // Your config here
}

// Implement token retrieval and storage
// (You're smart, you've got this!)

Creating a Tasks service

Time to get that Tasks client up and running:

ctx := context.Background()
client := config.Client(ctx, token)
tasksService, err := tasks.New(client)
if err != nil {
    log.Fatalf("Unable to create Tasks client: %v", err)
}

Basic operations

Now for the fun part! Let's play with some tasks:

Listing task lists

r, err := tasksService.Tasklists.List().Do()
if err != nil {
    log.Fatalf("Unable to retrieve task lists: %v", err)
}
for _, item := range r.Items {
    fmt.Printf("Task list name: %v\n", item.Title)
}

Creating a new task list

taskList := &tasks.TaskList{
    Title: "My Awesome Tasks",
}
r, err := tasksService.Tasklists.Insert(taskList).Do()
if err != nil {
    log.Fatalf("Unable to create task list: %v", err)
}
fmt.Printf("Task list created: %v\n", r.Title)

Adding tasks to a list

task := &tasks.Task{
    Title: "Learn Go",
}
r, err := tasksService.Tasks.Insert("taskListId", task).Do()
if err != nil {
    log.Fatalf("Unable to create task: %v", err)
}
fmt.Printf("Task created: %v\n", r.Title)

Advanced features

Want to level up? Try these:

Working with due dates

task.Due = "2023-12-31T23:59:59.000Z"

Managing task order

tasksService.Tasks.Move(taskListId, taskId).Previous(previousTaskId).Do()

Error handling and best practices

Always check for errors (you're doing great at this already!) and consider implementing exponential backoff for rate limiting. Your future self will thank you!

Testing the integration

Don't forget to test! Mock the Tasks API for unit tests:

func TestCreateTask(t *testing.T) {
    // Mock tasksService here
    // Test your heart out!
}

Conclusion

And there you have it! You've just built a rockin' Google Tasks API integration in Go. Pat yourself on the back – you've earned it!
