[6a3a178] | 1 | ### Install
|
---|
| 2 |
|
---|
| 3 | ```shell
|
---|
| 4 | npm install --save detect-node
|
---|
| 5 | ```
|
---|
| 6 |
|
---|
| 7 | ### Usage:
|
---|
| 8 |
|
---|
| 9 | ```js
|
---|
| 10 | var isNode = require('detect-node');
|
---|
| 11 |
|
---|
| 12 | if (isNode) {
|
---|
| 13 | console.log("Running under Node.JS");
|
---|
| 14 | } else {
|
---|
| 15 | alert("Hello from browser (or whatever not-a-node env)");
|
---|
| 16 | }
|
---|
| 17 | ```
|
---|
| 18 |
|
---|
| 19 | The check is performed as:
|
---|
| 20 | ```js
|
---|
| 21 | module.exports = false;
|
---|
| 22 |
|
---|
| 23 | // Only Node.JS has a process variable that is of [[Class]] process
|
---|
| 24 | try {
|
---|
| 25 | module.exports = Object.prototype.toString.call(global.process) === '[object process]'
|
---|
| 26 | } catch(e) {}
|
---|
| 27 |
|
---|
| 28 | ```
|
---|
| 29 |
|

| 30 | 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.
