os.arch()for node and the browser -- detect OS architecture
This module is used by WebTorrent Desktop to determine if the user is on a 32-bit vs. 64-bit operating system to offer the right app installer.
In Node.js, the
os.arch() method (and
process.arch property) returns a string
identifying the operating system CPU architecture for which the Node.js binary
This is not the same as the operating system CPU architecture. For example,
you can run Node.js 32-bit on a 64-bit OS. In that situation,
return a misleading 'x86' (32-bit) value, instead of 'x64' (64-bit).
Use this package to get the actual operating system CPU architecture.
BONUS: This package works in the browser too.
npm install arch
var arch = require('arch') console.log(arch()) // always returns 'x64' or 'x86'
In the browser, there is no spec that defines where this information lives, so we
check all known locations including
navigator.cpuClass to make a best guess.
If there is no affirmative indication that the architecture is 64-bit, then 32-bit will be assumed. This makes this package perfect for determining what installer executable to offer to desktop app users. If there is ambiguity, then the user will get the 32-bit installer, which will work fine even for a user with a 64-bit OS.
x64 means 64-bit and
x86 means 32-bit.
Here is some history behind these naming conventions:
