Today we get to learn how to export your data on Bluesky and inspect it. Since Bluesky follows an open standard, all the data on your profile can be compressed pretty heavily.

I first went to https://bsky.app and then hit “download my data”. I got a fairly small (~100 kilobytes) file called repo.car.

Downloaded from https://docs.bsky.app/blog/repo-export and lightly modified.

go mod init list_car_tool and go mod tidy in order to download the necessary repositories.

package main

import (
	"context"
	"fmt"
	"os"

	"github.com/bluesky-social/indigo/atproto/syntax"
	"github.com/bluesky-social/indigo/repo"
	"github.com/ipfs/go-cid"
)

func main() {
	ctx := context.Background()
	fi, err := os.Open("repo.car")
	if err != nil {
		panic(err)
	}

	// read repository tree in to memory
	r, err := repo.ReadRepoFromCar(ctx, fi)
	if err != nil {
		panic(err)
	}

	// extract DID from repo commit
	sc := r.SignedCommit()
	did, err := syntax.ParseDID(sc.Did)
	if err != nil {
		panic(err)
	}
	fmt.Printf("%s\n", did)

	// iterate over all of the records by key and CID
	err = r.ForEach(ctx, "", func(k string, v cid.Cid) error {
		fmt.Printf("%s\t%s\n", k, v.String())
		return nil
	})
	if err != nil {
		panic(err)
	}
}

Note that my DID for Bluesky is the following:

~/s/car$ dig +short _atproto.aidenfoxivey.com TXT
"did=did:plc:jghfpstu6aoqw3rtklzbaupt"

We can look this up because I use my custom domain aidenfoxivey.com as my username on Bluesky.

Let’s now run the code:

~/s/car$ go run list_car.go
did:plc:jghfpstu6aoqw3rtklzbaupt

app.bsky.feed.like/3lka4whgjkf2b        bafyreifh2vslm73t6xjcn4tuo3uqltltx2npffknes4b6u7lcymiccumvi

... snipped for brevity ...

Note at the bottom that I was fooling around with a service called tangled.sh, which is a Git service that has its discoverability powered by ATProto.

Here’s tangled.sh on the front page of git-scm.org! The only one here I’ve not tried now is radicle, which has always struck me as pretty cool. I must admit that I’m a bit of a bandwagon-er when it comes to trying new systems.
