### 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.
