An intent to bundle a standalone version of web3.js for browsers.

web3.js-browser

An intent to bundle a standalone version of web3.js for browsers, because web3.js SHOULD have a 2.x minified version for dApp developers.

FYI: web3.js#2623.

tl;dr

• Download scripts in build/ directory, or
• Use it as a typical npm module, or
• Import from CDN services like jsDelivr.

It is recommended to pin this bundle to some specific version, because web3.js varies dramatically across versions. You may waste much time debugging on some inconsistencies like me if used naively.

Build

git submodule init
git submodule update

# configure web3
cd web3.js
npm install
npm run build  # build web3 packages; we only need *.esm.js
cd ..

# build web3.js
yarn
npm run build

Web3.js caveats

The author was not careful enough to mistake v2.0.0-alpha for v2.0.0-alpha.1. To reduce confusion, this project deserves its own semantics versioning. See the releases page for details.

Scrypt

This bundle current follows v2.0.0-alpha.1. Current implementation deprecates scrypt dependency in higher versions of Node.js, likely because its lack of security. If you see the following message, it can be safely ignored.

WARNING in ./web3.js/packages/web3-eth-accounts/dist/web3-eth-accounts.esm.js
Module not found: Error: Can't resolve 'scrypt' in '/.../web3.js-browser/web3.js/packages/web3-eth-accounts/dist'
