Could you provide more context? All I see here is warnings. Webpack config files and scripts were removed from bcoin a while ago: https://github.com/bcoin-org/bcoin/pull/741

I'm trying to install bcoin browser from this site Run a bcoin full node in a web browser I tried it using superuser mode in my system here is the screenshot of it. Screenshot (8) I'm trying to give style to browser section like this Screenshot (9)

pinheadmz commented 4 years ago

Sorry the browser node guide is outdated now, and its such bad practice to run a node in a web browser anyway, its not really worth updating. We should probably just remove it.

You can take a look at this guide that explains how to use bpkg to compile individual modules for the browser: https://bcoin.io/guides/webapp

Or check out this repo, where I use bpkg to compile a bcoin full node into a cleaner bootstrap interface: https://github.com/pinheadmz/mobilebcoin

mkdir <new dir for your app>
cd <wherever your bcoin repo is installed>
bpkg --browser --standalone --plugin [ uglify-es --toplevel ] --name HD \
--output <your new app dir>/HD.js lib/hd/index.js

when I use this comment it gave error Invalid argument: --standalone.

pinheadmz commented 4 years ago

I believe standalone has been replaced with umd please read the documentation here: https://github.com/chjj/bpkg

I tried it didn't work and I got this error

pinheadmz commented 4 years ago

This command worked for me:

bpkg --browser --umd --name HD --plugin uglify-es  \
--output /home/pinheadmz/Desktop/work/bpkgtest/bcoin-hd.js lib/hd/index.js

Then create index.html:

<html>
<head></head> 
<body>
test

<script type="text/javascript" src="bcoin-hd.js"></script>
</body>
</html>

mrfoxie commented 4 years ago

if I add this HD.js script in browser folder and then include it in index.html wull it work

pinheadmz commented 4 years ago

yup. i think so :-) That's how this works: https://github.com/pinheadmz/bcoin-webapp

mrfoxie commented 4 years ago

You would have to do some patching yourself - the browser node guide, as you've discovered, is outdated and the actual webapp hosted on bcoin.io is running a patchset on top of a 2-year-old build of bcoin: https://github.com/pinheadmz/bcoin/commits/browserserver

If you really want to recreate the bcoin.io webapp you can try building it from that branch in my repo. Notice in that branch I've actually built four different bcoin's (testnet/main, spv/full) and commited the webpack output already.

okay i will check and tell you
