How to generate Bitcoin addresses by seed (BIP32 Mnemonic) using JS as well as in Electrum?

Question

Node.js

I need to implement bitcoin address generation by seed (BIP32 Mnemonic) similar to the method used in Electrum.
I tried to find ready-made solutions, I found ElectrumSeedTester, but the code there is so poorly organized that absolutely nothing is clear.
I tried to find blanks and tools, but they are all either without documentation (in general) or do something, but it’s not clear what.
In general, I couldn’t put together a normal concept for generating addresses in my head, although I’m ready to code a lot. (at the same time, it would be ideal to find an API for this, because the execution speed is not critical)

I found a lot of documentation and guides on seed generation, but no one wants to dedicate to calculating addresses from this seed.

In principle, any method implemented in Node.JS is suitable, and does not require opening or emulating a browser (http requests are possible)
