I'd like to know how to create https://github.com/ethereum/go-ethereum/blob/master/internal/jsre/deps/web3.js file automatically. It seems like bundled by some tools but I cannot find any mention or docs in the geth repo. Is there anyone who knows how to create bundled web3.js automatically embeded in geth? Thanks in advance for all your answers 🙂

FYI.

  • I already knows how web3 works and I used it several times because Im a developer.
  • Just wanna know how they bundled that web3 library and maintain that bundled file. (e.g. bundle web3 library using gulp, etc...)

    It is just a minified version of web3 v0.20.1. I think the hardest thing to upgrade it is generating a version that can run inside goja the javascript interpreter used by go-ethereum.

    Check the repo at that version github.com/ChainSafe/web3.js/blob/0.20.7 it has a command to build the minified file.

  • @Ismael Thanks for your detailed comment. It was really helpful. One more thing. How did you know that Geth use specified version v0.20.1? (Updated.) I knew that.. there is a specified version in the web3.js :)

    I'd check if there's a branch for the exact version v0.20.1, I'd also check the npm dependencies. I don't know if at that time web3 builds were reproducible.
