Hey there, @nezzard. Thanks for your question. What article are you referring to?

Thereā€™s a flag for that! All you need is: ipfs dag put --pin foo.json :slight_smile:

Thatā€™s essentially:

$ ipfs dag put foo.json
# outputs <hash>
$ ipfs pin add <hash>
# 'pinned <hash>'

Pinning foo.jsonā€™s hash will prevent that dag node from being removed.

Is child hashesh will keep alive with root hash?

I donā€™t know what you mean by child hash here. If I havenā€™t answered your question, can you say it another way?

Note that pinning is not yet available in js-ipfs. We are super close to adding it, though. It should be in the next release or two.

Is pinning a DAG supported yet in the IPFS javascript API? Thx
