long-polling-redis | Example App showing client side long polling | Application Framework library

long-polling-redis is a JavaScript library typically used in Server, Application Framework, Spring Boot applications. long-polling-redis has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

A naive approach to front-end querying of the backend for new emails, messages, alerts, etc. is to poll every x seconds. In Javascript, this is usually done using the setInterval() function. For example, if one were to design a email app similar to GMail, the user will expect new incoming messages to be shown in the inbox count automatically (i.e. without having to constantly refresh the page). Polling again and again is a waste of resources on both the client and server, especially when the frequency of polling is far greater than new incoming messages are received. A better way to approach the problem is by using async requests on a pubsub channel on the backend, along with a recursive function on the front-end that only makes new requests when the old has actually returned.
