RESP2 -> JS

• Integer (:) => number
• Simple String (+) => string | Buffer
• Blob String ($) => string | Buffer
• Simple Error (-) => ErrorReply
• Array (*) => Array

RESP3 -> JS

• Null (_) => null
• Boolean (#) => boolean
• Number (:) => number | string
• Big Number (() => BigInt | string
• Double (,) => number | string
• Simple String (+) => string | Buffer
• Blob String ($) => string | Buffer
• Verbatim String (=) => string | Buffer | VerbatimString (TODO: VerbatimString typedoc link)
• Simple Error (-) => ErrorReply
• Blob Error (!) => ErrorReply
• Array (*) => Array
• Set (~) => Array | Set
• Map (%) => object | Map | Array
• Push (>) => Array => PubSub push/'push' event

NOTE: the first type is the default type

Map keys and Set members

When decoding Map to Map | object or Set to Set, keys/members (respectively) of type "Simple String" or "Blob String" will be decoded as strings (ignoring flags) to allow lookup by type. If you need them as Buffers, make sure to decode Maps/Sets as Arrays.

Not Implemented

These parts of RESP3 are not yet implemented in Redis itself (at the time of writing), so are not yet implemented in the Node-Redis client either:

• Attribute type
• Streamed strings
• Streamed aggregated data types
