+### 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.
