I have downloaded and installed Bitcoin full node on my Linux server and I'd like to start working with the bitcoin core to create wallet, addresses, and transactions. What is the best JS libraries available to facilitate using all the necessary methods in this regard?
I highly recommend bcoin:
It is a nodejs library that can also run a fully validating node, SPV node, and BIP44 wallet. It's used in production by many long-standing bitcoin companies such as Purse.io
You can even use the bcoin client to make RPC calls to bitcoin core, and of course you do not need to run the bcoin full node to take advantage of the library for TX construction and wallet functions.
https://github.com/bitcoinjs/bitcoinjs-lib Bitcoinjs-lib lets you create and sign transactions
The results will show you the most popular libraries on github at the moment!
