For example, +you can run Node.js 32-bit on a 64-bit OS. In that situation, `os.arch()` will +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.** + +## install + +``` +npm install arch +``` + +## usage + +```js +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.userAgent`, `navigator.platform`, +and `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. + +For reference, `x64` means 64-bit and `x86` means 32-bit. + +Here is some history behind these naming conventions: + +- https://en.wikipedia.org/wiki/X86 +- https://en.wikipedia.org/wiki/IA-32 +- https://en.wikipedia.org/wiki/X86-64 + +## Node.js proposal - `os.sysarch()` + +Note: There is +[a proposal](https://github.com/nodejs/node-v0.x-archive/issues/2862#issuecomment-103942051) +to add this functionality to Node.js as `os.sysarch()`. + +## license + +MIT.
