D4J Stores

Implementations of the Discord4J Store (Discord entity cache) including an extensive test suite.

Postgres

An implementation backed by everyone's favorite open sauce database PostgreSQL.

Gradle

repositories {
	maven { url "https://jitpack.io" }
}

dependencies {
	implementation "dev.capybaralabs.d4j-store:postgres:x.y.z"
}

Example Usage

fun connectionFactory(): ConnectionFactory {
	return ConnectionFactories.get(
		ConnectionFactoryOptions.builder()
			.option(ConnectionFactoryOptions.DRIVER, "postgresql")
			.option(ConnectionFactoryOptions.HOST, "127.0.0.1")
			.option(ConnectionFactoryOptions.PORT, 5432)
			.option(ConnectionFactoryOptions.USER, "cache")
			.option(ConnectionFactoryOptions.PASSWORD, "cache")
			.option(ConnectionFactoryOptions.DATABASE, "cache")
			.build()
	)
}

fun connectionPool(): ConnectionPool {
	val configuration = ConnectionPoolConfiguration.builder(connectionFactory())
		.maxIdleTime(Duration.ofMillis(1000))
		.maxSize(20)
		.maxAcquireTime(Duration.ofSeconds(5))
		.build()

	return ConnectionPool(configuration)
}

fun postgresStoreLayout(): StoreLayout {
	return PostgresStoreLayout(connectionPool())
}

fun store(): Store {
	return Store.fromLayout(postgresStoreLayout())
}

fun gatewayBootstrap(discordClient: DiscordClient): GatewayBootstrap<GatewayOptions> {
	return discordClient
		.gateway()
		.setStore(store())
		.withEventDispatcher { ed ->
			ed.on(Event::class.java)
				.doOnNext { logger().trace("Event received ${it.javaClass.simpleName}") }
				.retry()
		}
}

Redis

An implementation backed by everyone's second favorite open sauce database Redis.

Gradle

repositories {
	maven { url "https://jitpack.io" }
}

dependencies {
	implementation "dev.capybaralabs.d4j-store:redis:x.y.z"
}

Example Usage

fun connectionFactory(): ReactiveRedisConnectionFactory {
	val redisUri = RedisURI.create("redis://localhost:6379/0")
	val redisConfiguration = LettuceConnectionFactory.createRedisConfiguration(redisUri)
	val connectionFactory = LettuceConnectionFactory(redisConfiguration)
	connectionFactory.afterPropertiesSet()

	return connectionFactory
}

fun redisStoreLayout(): StoreLayout {
	return RedisStoreLayout(connectionFactory)
}

fun store(): Store {
	return Store.fromLayout(redisStoreLayout())
}

fun gatewayBootstrap(discordClient: DiscordClient): GatewayBootstrap<GatewayOptions> {
	return discordClient
		.gateway()
		.setStore(store())
		.withEventDispatcher { ed ->
			ed.on(Event::class.java)
				.doOnNext { logger().trace("Event received ${it.javaClass.simpleName}") }
				.retry()
		}
}
