Streams Demo

Streams allow efficient rendering of large lists. Instead of re-sending the entire list on each change, only the operations (insert, delete) are sent over the websocket.

The "stream" key in the diff contains: [stream_ref, [[dom_id, at, limit], ...], [deletes], reset?]

• stream_ref: Stream name/reference
• inserts: Array of [dom_id, at, limit] tuples (-1=append, 0=prepend)
• deletes: Array of DOM IDs to remove
• reset: When true, clears all items before applying inserts
