rsmq-promise - Promise interface for RSMQ
A lightweight message queue for Node.js that requires no dedicated queue server. Just a Redis server.
Usage
- After creating a queue you can send messages to that queue.
- The messages will be handled in a FIFO (first in first out) manner unless specified with a delay.
- Every message has a unique
id
that you can use to delete the message. - The
sendMessage
method will return theid
for a sent message. - The
receiveMessage
method will return anid
along with the message and some stats. - Should you not delete the message it will be eligible to be received again after the visibility timeout is reached.
- Please have a look at the
createQueue
andreceiveMessage
methods described below for optional parameters like visibility timeout and delay.
