| ### Install |
| |
| ```shell |
| npm install --save detect-node |
| ``` |
| |
| ### Usage: |
| |
| ```js |
| var isNode = require('detect-node'); |
| |
| if (isNode) { |
| console.log("Running under Node.JS"); |
| } else { |
| alert("Hello from browser (or whatever not-a-node env)"); |
| } |
| ``` |
| |
| The check is performed as: |
| ```js |
| module.exports = false; |
| |
| // Only Node.JS has a process variable that is of [[Class]] process |
| try { |
| module.exports = Object.prototype.toString.call(global.process) === '[object process]' |
| } catch(e) {} |
| |
| ``` |
| |
| Thanks to Ingvar Stepanyan for the initial idea. This check is both **the most reliable I could find** and it does not use `process` env directly, which would cause browserify to include it into the build. |
