Introduction

Hey there, fellow Go enthusiast! Ready to supercharge your productivity with a custom Todoist integration? You're in the right place. We'll be diving into the Todoist API and crafting a sleek Go application to manage your tasks programmatically. Buckle up!

Prerequisites

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

Go installed on your machine (you're a Gopher, right?)
A Todoist API token (grab one from your Todoist settings)

Setting up the project

Let's kick things off:

mkdir todoist-go-integration
cd todoist-go-integration
go mod init github.com/yourusername/todoist-go-integration

Now, let's grab the HTTP client we'll need:

go get github.com/go-resty/resty/v2

Authentication

Todoist uses a simple token-based auth. Let's set it up:

package main

import (
    "github.com/go-resty/resty/v2"
)

const (
    baseURL = "https://api.todoist.com/rest/v2"
    token   = "YOUR_API_TOKEN_HERE"
)

func main() {
    client := resty.New().
        SetBaseURL(baseURL).
        SetHeader("Authorization", "Bearer "+token)
}

Making API requests

Now that we're authenticated, let's make some requests:

func getTasks() ([]Task, error) {
    var tasks []Task
    _, err := client.R().
        SetResult(&tasks).
        Get("/tasks")
    return tasks, err
}

Implementing core functionalities

Let's add some CRUD operations:

func createTask(content string) error {
    _, err := client.R().
        SetBody(map[string]string{"content": content}).
        Post("/tasks")
    return err
}

func updateTask(id string, content string) error {
    _, err := client.R().
        SetBody(map[string]string{"content": content}).
        Post("/tasks/" + id)
    return err
}

func deleteTask(id string) error {
    _, err := client.R().
        Delete("/tasks/" + id)
    return err
}

Error handling and logging

Don't forget to handle those errors:

if err != nil {
    log.Printf("Error: %v", err)
    return
}

Testing the integration

Write some tests to keep things robust:

func TestGetTasks(t *testing.T) {
    tasks, err := getTasks()
    if err != nil {
        t.Fatalf("Error getting tasks: %v", err)
    }
    if len(tasks) == 0 {
        t.Log("No tasks found, but request was successful")
    }
}

Optimizations and best practices

Remember to respect rate limits and cache when possible:

client.SetRetryCount(3).
    SetRetryWaitTime(5 * time.Second)

Conclusion

And there you have it! You've just built a Todoist integration in Go. Pretty cool, right? You can now manage your tasks programmatically, opening up a world of automation possibilities. Why not try extending it with your own custom features?
