### 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.
