streamable-topic | Event streaming concepts implemented on top

streamable-topic is a TypeScript library. streamable-topic has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Event streaming concepts implemented on top of an abstracted storage backend. A topic is a list of ordered messages containing known payloads. You may push new messages to the end of a topic, and consume messages starting from some position. A consumer will keep track of the last message consumed and will always stream new messages as they arrive for you. Messages are always guaranteed to be streamed in the correct order. Produce messages with logCompactIds to notify the backend that any previous message with the same id is now redundant and can be removed from the storage engine automatically. Use a Topic Setter in conjunction with one or many Topic Consumers to build a Topic Processor. A processor is a recoverable process that transforms data from one topic to another. Specify the Payload type when you create the Comsumer Producer instances. Make sure that types are at least backwards compatible with existing data, otherwise you may accidently stream something with unexpected incorrect typings. Use optional keys or a whole new version that the topic supports. These concepts are relatively simple but a powerful building block for event based systems.
