# gobot-bsky

Gobot-bsky - a simple GO lib to write Bluesky bots

## Usage example

Has to provide:

* a handle - example bluesky handle: "example.bsky.social"
* an apikey - is used for authetication and the retrieval of the access token and refresh token. To create a new one: Settings --> App Passwords
* the server (PDS) - the Bluesky's "PDS Service" is bsky.social.

```go
import gobot "github.com/danrusei/gobot-bsky"

func main() {

godotenv.Load()
handle := os.Getenv("HANDLE")
apikey := os.Getenv("APIKEY")
server := "https://bsky.social"

ctx := context.Background()

agent := gobot.NewAgent(ctx, server, handle, apikey)
agent.Connect(ctx)

// Facets Section
// =======================================
// Facet_type coulf be Facet_Link, Facet_Mention or Facet_Tag
// based on the selected type it expect the second argument to be URI, DID, or TAG
// the last function argument is the text, part of the original text that is modifiend in Richtext

post1, err := gobot.NewPostBuilder("Hello to Bluesky, the coolest open social network").
WithFacet(gobot.Facet_Link, "https://docs.bsky.app/", "Bluesky").
WithFacet(gobot.Facet_Tag, "bsky", "open social").
Build()
if err != nil {
fmt.Printf("Got error: %v", err)
}

cid1, uri1, err := agent.PostToFeed(ctx, post1)
if err != nil {
fmt.Printf("Got error: %v", err)
} else {
fmt.Printf("Succes: Cid = %v , Uri = %v", cid1, uri1)
}

// Embed Links section
// =======================================

u, err := url.Parse("https://go.dev/")
if err != nil {
log.Fatalf("Parse error, %v", err)
}

previewUrl, err := url.Parse("https://www.freecodecamp.org/news/content/images/2021/10/golang.png")
if err != nil {
log.Fatalf("Parse error, %v", err)
}
previewImage := gobot.Image{
Title: "Golang",
Uri: *previewUrl,
}
previewImageBlob, err := agent.UploadImage(ctx, previewImage)
if err != nil {
log.Fatalf("Parse error, %v", err)
}

post2, err := gobot.NewPostBuilder("Hello to Go on Bluesky").
WithExternalLink("Go Programming Language", *u, "Build simple, secure, scalable systems with Go", *previewImageBlob).
Build()
if err != nil {

}

if err != nil {
fmt.Printf("Got error: %v", err)
} else {
fmt.Printf("Succes: Cid = %v , Uri = %v", cid2, uri2)
}

// Embed Images section
// =======================================
images := []gobot.Image{}

url1, err := url.Parse("https://www.freecodecamp.org/news/content/images/2021/10/golang.png")
if err != nil {
log.Fatalf("Parse error, %v", err)
}
images = append(images, gobot.Image{
Title: "Golang",
Uri: *url1,
})

blobs, err := agent.UploadImages(ctx, images...)
if err != nil {
log.Fatalf("Parse error, %v", err)
}

post3, err := gobot.NewPostBuilder("Gobot-bsky - a simple golang lib to write Bluesky bots").
WithImages(blobs, images).
Build()
