multicore-webpack v1.2.4

multicore-webpack

multicore-webpack takes advantage of the multiple cores in your computer's processor to get your bundles out as fast as possible by spinning up a child process for each webpack config you target, and kills them all if one fails.

Many webpack configs do so much file I/O and computationally intensive operations to build your bundles, but Node.js is not designed to take advantage of multicore processors.

usage: multicore-webpack NAME[,NAME...] ::: ARGS...

    NAME   The name argument of a webpack 3+ config.

    ARGS   The usual args you pass to webpack to build your config.
           This can include the --config option as well, if you do not use
           `webpack.config.js`.

Quickstart

webpack.config.js

module.exports = [ require('./a.webpack.js'), require('b.webpack.js') ];

npm install -g multicore-webpack
multicore-webpack alpha,bravo ::: --env dev

Dependencies

• webpack >= 3.0.0
• Runs on basically any POSIX-compatible system (BSD, GNU, Linux, macOS).
• Windows, cygwin and MinGW are unsupported. (PRs accepted!)
• A C compiler: clang and gcc tested.

Limitations

• There's no speed improvement if you're only building a single webpack config.

• Issues #3 applies if you are throwing more config targets than you have CPU cores.

• There is a hard limit of 99 webpack config targets at the moment to safeguard against a fork bomb. This can be raised to 65536 as soon as #3 is resolved.

Contributing

• Submit a PR ;)
• Target is C99; no features newer than C99 should berelied on, but it is recommended to compile targeting C11.
• CFLAGS include -fstrict-aliasing.
