BSV Library Version | HD Keys Confussion

[imkrishnaagrawal]

Hi Everyone,

I am new to bsv ecosystem and have started a project using typescript/javascript. the obvious choice was bsv npm package as suggested by bsv official website and also followed along some courses however I am facing challenges understanding the versions , maintenance and future of bsv library. most of courses I followed at satolearn and other places are using old version of library which is 1.5.x and also moneybutton documentation is using 0.30.0 (https://about.moneybutton.com/docs/button/mb-crypto-operations). I am facing issue when creating HD Private and Public keys using Mnemonic. while looking at issues I found a solution however it is not working bsv.Mnemonic and bsv.HDPrivKey are undefined. I am using bsv@2.0.10.

const mnemonic = new bsv.Mnemonic()
const hdPrivKey = bsv.HDPrivKey.fromSeed(mnemonic.toSeed())
const someKey = hdPrivKey.deriveChild("m/5/2/8") // Private key
const somePubkey = someKey.publicKey
const address = somePubkey.toAddress()
console.log(address);

Errors:

const mnemonic = new bsv.Mnemonic()
                 ^
TypeError: bsv.Mnemonic is not a constructor

const hdPrivKey = bsv.HDPrivKey.fromSeed(mnemonic.toSeed())
                                ^
TypeError: Cannot read properties of undefined (reading 'fromSeed')

I need suggestion to get some understanding around the issue. Other developers might be facing similar challenges.

The API has changed substantially between bsv-legacy and the updated bsv@2.0.10

const seed = bsvjs.Bip39.fromRandom().seed
const hdPrivKey = bsvjs.Bip32.fromSeed(seed)
const someKey = hdPrivKey.derive("m/5/2/8")
const somePubkey = someKey.pubKey
const address = bsvjs.Address.fromPubKey(somePubkey).toString()

console.log(address)

using bips as the naming scheme is really confusing to newcomers and fails at the target purpose of It should not be necessary to read the source code of a class or function to know how to use it / so that other developers find the code easy to understand.

developers, especially newcomers, should not have to learn by heart which BIP number corresponds to a well-known feature of any bitcoin library, the feature should be described by its name for clarity and ease of use
