method
Blocking move from one list to another
Atomically moves an element from source to destination list, blocking until an element is available or the timeout expires. Allows specifying which end to pop from (LEFT/RIGHT) and which end to push to (LEFT/RIGHT).
Source list key
Destination list key
Direction to pop from source: "LEFT" or "RIGHT"
Direction to push to destination: "LEFT" or "RIGHT"
Timeout in seconds (can be fractional, 0 = block indefinitely)
Promise that resolves with the moved element or null on timeout
// Move from right of source to left of destination (like BRPOPLPUSH)
const element = await redis.blmove("mylist", "otherlist", "RIGHT", "LEFT", 1.0);
if (element) {
console.log(`Moved element: ${element}`);
}
// Move from left to left
await redis.blmove("list1", "list2", "LEFT", "LEFT", 0.5);
