# Godo

Godo is a Go client library for accessing the DigitalOcean V2 API.

You can view the client API docs here: [http://godoc.org/github.com/digitalocean/godo](http://godoc.org/github.com/digitalocean/godo)

You can view DigitalOcean API docs here: [https://developers.digitalocean.com/documentation/v2/](https://developers.digitalocean.com/documentation/v2/)


## Usage

```go
import "github.com/digitalocean/godo"
```

Create a new DigitalOcean client, then use the exposed services to
access different parts of the DigitalOcean API.

### Authentication

Currently, Personal Access Token (PAT) is the only method of
authenticating with the API. You can manage your tokens
at the DigitalOcean Control Panel [Applications Page](https://cloud.digitalocean.com/settings/applications).

You can then use your token to create a new client:

```go
package main

import (
	"context"
	"github.com/digitalocean/godo"
	"golang.org/x/oauth2"
)

const (
    pat = "mytoken"
)

type TokenSource struct {
	AccessToken string
}

func (t *TokenSource) Token() (*oauth2.Token, error) {
	token := &oauth2.Token{
		AccessToken: t.AccessToken,
	}
	return token, nil
}

func main() {
	tokenSource := &TokenSource{
		AccessToken: pat,
	}

	oauthClient := oauth2.NewClient(context.Background(), tokenSource)
	client := godo.NewClient(oauthClient)
}
```

## Examples


To create a new Droplet:

```go
dropletName := "super-cool-droplet"

createRequest := &godo.DropletCreateRequest{
    Name:   dropletName,
    Region: "nyc3",
    Size:   "s-1vcpu-1gb",
    Image: godo.DropletCreateImage{
        Slug: "ubuntu-14-04-x64",
    },
}

ctx := context.TODO()

newDroplet, _, err := client.Droplets.Create(ctx, createRequest)

if err != nil {
    fmt.Printf("Something bad happened: %s\n\n", err)
    return err
}
```

### Pagination

If a list of items is paginated by the API, you must request pages individually. For example, to fetch all Droplets:

```go
func DropletList(ctx context.Context, client *godo.Client) ([]godo.Droplet, error) {
    // create a list to hold our droplets
    list := []godo.Droplet{}

    // create options. initially, these will be blank
    opt := &godo.ListOptions{}
    for {
        droplets, resp, err := client.Droplets.List(ctx, opt)
        if err != nil {
            return nil, err
        }

        // append the current page's droplets to our list
        for _, d := range droplets {
            list = append(list, d)
        }

        // if we are at the last page, break out the for loop
        if resp.Links == nil || resp.Links.IsLastPage() {
            break
        }

        page, err := resp.Links.CurrentPage()
        if err != nil {
            return nil, err
        }

        // set the page we want for the next request
        opt.Page = page + 1
    }

    return list, nil
}
```

## Versioning

Each version of the client is tagged and the version is updated accordingly.

Since Go does not have a built-in versioning, a package management tool is
recommended - a good one that works with git tags is
[gopkg.in](http://labix.org/gopkg.in).

To see the list of past versions, run `git tag`.
