Requirements#

To run this project, you will need the following:

Rust 1.85+ (Cargo)

Installation#

Clone the repository:

git clone https://github.com/ewanc26/bluesky-avatar-updater.git
cd bluesky-avatar-updater

Build the project:
```
cargo build --release
```

Create a .env file in the assets/ directory (or the root) and add your environment variables:

ENDPOINT=https://bsky.social
HANDLE=your_handle.bsky.social
PASSWORD=your_app_password
DID=did:plc:your_did
UPDATE_BANNER=false

Create assets/cids.json with hourly blob mappings:

{
  "00": {
    "avatar": "cid_for_midnight",
    "banner": "banner_cid_for_midnight"
  },
  "01": { "avatar": "cid_for_1am", "banner": "banner_cid_for_1am" }
}

Usage#

Run the updater from the repository root:

cargo run --release

On start-up, the script will:

Load configuration and environment variables.
Confirm the endpoint is healthy.
Read the CID mapping from assets/cids.json.
Select the avatar/banner CID for the current hour.
Log in to Bluesky and update the profile record.
Ensure an hourly cron job exists for future runs.
