# Watermill Comfylite Pub/Sub
This is an unofficial `sqlite3` provider leveraging [`comfylite3`](https://github.com/davidroman0O/comfylite3) for the [Watermill](https://watermill.io/) project.
Since there are a lot of issues using `sqlite3` for either in memory or with a file when used in concurrency situations, `comfylite3` provide a while bypass for us.
All you need to use `comfymill.NewDatabase`, use your own parameters (check `comfylite3` docs) and tadam!
# Install
```
go get -u github.com/davidroman0O/watermill-comfymill
```
# Example
It's a simple implementation of the MySql code for Sqlite3, here an example usage of it:
```go
comfy, err := comfylite3.New(comfylite3.WithMemory())
if err != nil {
panic(err)
}
db := comfylite3.OpenDB(comfy)
if err != nil {
panic(err)
}
subscriber, err := sql.NewSubscriber(
db,
sql.SubscriberConfig{
SchemaAdapter: comfymill.DefaultSQLite3Schema{},
OffsetsAdapter: comfymill.DefaultSQLite3OffsetsAdapter{},
InitializeSchema: true,
},
logger,
)
if err != nil {
panic(err)
}
messages, err := subscriber.Subscribe(context.Background(), "example_topic")
if err != nil {
panic(err)
}
go process(messages)
publisher, err := sql.NewPublisher(
db,
sql.PublisherConfig{
SchemaAdapter: comfymill.DefaultSQLite3Schema{},
},
logger,
)
if err != nil {
panic(err)
}
```
