Step by Step Guide to Building a Netlify API Integration in Go

Introduction

Hey there, fellow developer! Ready to supercharge your Go projects with Netlify's awesome API? You're in the right place. We're going to walk through building a Netlify API integration that'll make your deployments smoother than ever. Let's dive in!

Prerequisites

Before we get our hands dirty, make sure you've got:

• Go installed on your machine (you're a Go dev, so I'm sure you're covered!)
• A Netlify account and API token (grab one from your account settings if you haven't already)

Setting up the project

Let's kick things off by setting up our project:

mkdir netlify-api-integration
cd netlify-api-integration
go mod init netlify-api-integration

Now, let's grab the Netlify Go client:

go get github.com/netlify/open-api/go/plumbing

Authentication

Time to get that API token working for us. Create a new file called main.go and add this:

package main

import (
    "context"
    "fmt"
    "os"

    "github.com/netlify/open-api/go/plumbing"
    "github.com/netlify/open-api/go/porcelain"
)

func main() {
    token := os.Getenv("NETLIFY_AUTH_TOKEN")
    client := porcelain.NewClient(&porcelain.ClientOptions{
        AccessToken: token,
    })

    // We'll add more code here soon!
}

Pro tip: Set your token as an environment variable to keep it safe!

Basic API Operations

Let's fetch some site info:

sites, err := client.ListSites(context.Background(), nil)
if err != nil {
    fmt.Printf("Error listing sites: %s\n", err)
    return
}

for _, site := range sites {
    fmt.Printf("Site: %s (%s)\n", site.Name, site.URL)
}

Want to see your recent deployments? Add this:

deploys, err := client.ListSiteDeploys(context.Background(), sites[0].ID, nil)
if err != nil {
    fmt.Printf("Error listing deploys: %s\n", err)
    return
}

for _, deploy := range deploys {
    fmt.Printf("Deploy: %s (%s)\n", deploy.ID, deploy.State)
}

Advanced Operations

Feeling adventurous? Let's create a new deploy:

deploy, err := client.CreateSiteDeploy(context.Background(), sites[0].ID, plumbing.DeployFiles{
    Files: map[string]string{
        "index.html": "<h1>Hello, Netlify!</h1>",
    },
})
if err != nil {
    fmt.Printf("Error creating deploy: %s\n", err)
    return
}

fmt.Printf("New deploy created: %s\n", deploy.ID)

Error Handling and Best Practices

Always check for errors, folks! And remember, Netlify has rate limits. Be a good API citizen:

import "time"

// ... in your code
time.Sleep(time.Second) // Add a delay between API calls

Testing the Integration

Testing is crucial. Here's a quick example using the testing package:

func TestListSites(t *testing.T) {
    client := porcelain.NewClient(&porcelain.ClientOptions{
        AccessToken: "test-token",
    })

    // Mock the API response here

    sites, err := client.ListSites(context.Background(), nil)
    if err != nil {
        t.Fatalf("Expected no error, got %v", err)
    }

    if len(sites) == 0 {
        t.Fatal("Expected sites, got none")
    }
}

Deployment and Usage

Build your integration:

go build

Now you've got a powerful Netlify API integration at your fingertips!

Conclusion

And there you have it! You've just built a Netlify API integration in Go. Pretty cool, right? Remember, this is just scratching the surface. The Netlify API has tons more to offer, so don't be afraid to explore and experiment.

Now go forth and deploy with confidence! Happy coding! 🚀
