## explanation

### client-metadata.json

the `client_id` is different between `pnpm run start` and `pnpm run dev`. see `https://localhost:3000/oauth/client-metadata.json` for this.

### local-infra

i think this is the server configuration required for self-hosting.

https://github.com/likeandscribe/frontpage/tree/main/packages/frontpage/local-infra

since plc gives an error, do the following. probably a postgres database is required. there is no need to open ports.

```yml
  plc:
    image: ghcr.io/bluesky-social/did-method-plc:plc-f2ab7516bac5bc0f3f86842fa94e996bd1b3815b
    container_name: plc
    restart: unless-stopped
    ports:
      - '4000:8080'
    depends_on:
      - plc_db
    env_file:
      - ./plc.env

  plc_db:
    image: postgres:16-alpine
    restart: always
    env_file:
      - ./postgres.env
    volumes:
      - ./configs/postgres/init/:/docker-entrypoint-initdb.d/
      - ./data/postgres/:/var/lib/postgresql/data/
    healthcheck:
      test: "pg_isready -U $$POSTGRES_USER -d $$POSTGRES_DB"
      interval: 5s
      retries: 20
```

```sh
# plc.env
DEBUG_MODE=1
LOG_ENABLED=true
LOG_LEVEL=debug
LOG_DESTINATION=1
PORT=8080
DATABASE_URL=postgres://postgres:postgres@plc_db/plc
DB_CREDS_JSON='{"username":"postgres","password":"postgres","host":"plc_db","port":"5432","database":"plc"}'
ENABLE_MIGRATIONS=true
DB_MIGRATE_CREDS_JSON='{"username":"postgres","password":"postgres","host":"plc_db","port":"5432","database":"plc"}'
```

```sh
# configs/postgres/init/init.sql
-- PLC
CREATE DATABASE plc;
GRANT ALL PRIVILEGES ON DATABASE plc TO postgres;
```

### pds

first, i think you need to get the pdsurl with oauth(session). if you have a session, you can perform operations such as posting.

```sh
$ cd $dir/packages/frontpage
./lib/data/user.ts:  const pdsUrl = await getPdsUrl(session.user.did);
```

it seems that drainpipe searches for `fyi.unravel.frontpage(collection)` in pds and commits it to firehose subscriberepos. if you change these two parts, it will not work with `frontpage.fyi`.

```rust
// https://github.com/likeandscribe/frontpage/blob/e7444ec6c19f0ccef3776f04702c3bb033ed3bfc/packages-rs/drainpipe/src/main.rs#L66-L97
// RELAY_URL=wss://bsky.network
let mut ws_request = format!(
        "{}/xrpc/com.atproto.sync.subscribeRepos{}",
        relay_url, query_string
)

/// Process a message from the firehose. Returns the sequence number of the message or an error.
async fn process(message: Vec<u8>, ctx: &mut Context) -> Result<i64, ProcessError> {
    let (_header, data) = firehose::read(&message).map_err(|e| ProcessError {
        inner: e.into(),
        seq: -1,
        source: message.clone().into(),
        kind: ProcessErrorKind::DecodeError,
    })?;
    let sequence = match data {
        firehose::SubscribeRepos::Commit(commit) => {
            let frontpage_ops = commit
                .operations
                .iter()
                .filter(|op| op.path.starts_with("com.unravel.example."))
                //.filter(|op| op.path.starts_with("fyi.unravel.frontpage."))
                .collect::<Vec<_>>();
            if !frontpage_ops.is_empty() {
                process_frontpage_ops(&frontpage_ops, &commit, &ctx)
                    .map_err(|e| ProcessError {
                        seq: commit.sequence,
                        inner: e,
                        source: message.clone().into(),
                        kind: ProcessErrorKind::ProcessError,
                    })
                    .await?;
            }
            commit.sequence
        }
        msg => msg.sequence(),
    };

    Ok(sequence)
}
```

色を変更するには`packages/frontpage/app/globals.css `を変更します。

```css
--primary: 210 100% 50%; /* HSLカラーで青色を定義 */
--primary-foreground: 0 0% 100%; /* 白色のテキスト */
```
