## 📖 Documentation

### Further resources

- [**Substreams** documentation](https://substreams.streamingfast.io)

- [**Slack** API documentation](https://api.slack.com/automation)

### Protobuf

- [`sf.substreams.entity.v1.EntityChanges`](https://github.com/streamingfast/substreams-entity-change/blob/develop/proto/entity/v1/entity.proto)

## CLI

[**Use pre-built binaries**](https://github.com/pinax-network/substreams-sink-slack/releases)

- [x] MacOS

- [x] Linux

- [x] Windows

**Install** globally via npm

```

$ npm install -g substreams-sink-slack

```

**Run**

```

$ substreams-sink-slack run [options] 

```

### Formatting

Supports `JSON` and `YAML` format for configuration file. Example of `config.json` format configuration file:

```json

[

    {

        "entity": "Transfer",

        "chat_ids": [

            "U0G9QF9C6"

        ],

        "message": "This *{user_id}* made a _transaction_ with id `{trx_id}`"

    },

    {

        "entity": "Grants",

        "chat": [

            "U0G9QF9C6"

        ],

        "message": "This `{grant}`"

    }

]

```

Text between `{}` are field names and are used as labels for message templating. In the example above, all `EntityChanges` messages coming from the substream with `entity` key having `Transfer` as value, will be sent to [Slack](https://slack.com/) channel or user with id `U0G9QF9C6`, as specified in the first json object.
