An example of multi-platform JavaScript package distributed via GitHub
You can check how it works via:
npm add larixer/multi-platform#1.0.0
Go into node_modules and verify that user-facing multi-platform package is installed and native package multi-platform-{os}-{cpu} for your current platform package is installed. Provided OSes: [linux, darwin, win32]. Provided CPUs: [x64].
Note, that 4 branches are used for distribution, each branch is tagged with each package release. Branch for user-facing package is main. 3 other branches are used for native packages: linux-x64, darwin-x64 and win32-x64.
