* Replace Nats with Nats Jestream For PubSub Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add Stream Description Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Subscribe using wildcard Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add consumers description Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Remove unused queue variable Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add extra configs to stream Signed-off-by: Rodney Osodo <socials@rodneyosodo.com> * Use inline error handling Signed-off-by: Rodney Osodo <socials@rodneyosodo.com> * Fix connection leak in NATS publisher The publisher struct in pkg/messaging/nats/publisher.go was modified to include a new `conn` field of type `*broker.Conn`. This change was made to fix a connection leak issue in the NATS publisher. The `NewPublisher` function was updated to assign the `conn` parameter to the new `conn` field in the publisher struct. Additionally, the `Close` method in the publisher struct was modified to close the `conn` connection. This commit fixes the connection leak issue in the NATS publisher and ensures that connections are properly closed. Signed-off-by: Rodney Osodo <socials@rodneyosodo.com> * feat(messaging): Add support for durable consumers This commit adds support for durable consumers to NATS JS in the messaging package. To support this functionality, the `strings` package has been imported in the `pubsub.go` file to check the topic. Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat : remove internal logic to keep subscribers Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat(messaging): add function to format consumer name This commit adds a new function to the `pubsub` package in the `messaging` module. The function is called `formatConsumerName` and is used to generate a consumer name for NATS messaging. The function takes two parameters, `topic` and `id`, and returns a formatted consumer name. The consumer name is generated by concatenating the `topic` and `id` parameters, with some restrictions on the characters that can be used. This function will be useful for creating durable subscriptions in NATS messaging.
