Referring https://docs.couchbase.com/nodejs-sdk/2.6/datastructures.html , couchbase supports data structure but when i tried to find from Bucket class with typescript version (2.4.1) , I am not able to find it. I can see in npm module with couchbase 2.6 which javascript version but i have to do with Typescript.
3.0 will support it as of the next release by built in definitions which are automatically generated based on the same inline docblocks that do our documentation.
