# npm-run-path [](https://travis-ci.org/sindresorhus/npm-run-path) |
|
|
|
> Get your [PATH](https://en.wikipedia.org/wiki/PATH_(variable)) prepended with locally installed binaries |
|
|
|
In [npm run scripts](https://docs.npmjs.com/cli/run-script) you can execute locally installed binaries by name. This enables the same outside npm. |
|
|
|
|
|
## Install |
|
|
|
``` |
|
$ npm install npm-run-path |
|
``` |
|
|
|
|
|
## Usage |
|
|
|
```js |
|
const childProcess = require('child_process'); |
|
const npmRunPath = require('npm-run-path'); |
|
|
|
console.log(process.env.PATH); |
|
//=> '/usr/local/bin' |
|
|
|
console.log(npmRunPath()); |
|
//=> '/Users/sindresorhus/dev/foo/node_modules/.bin:/Users/sindresorhus/dev/node_modules/.bin:/Users/sindresorhus/node_modules/.bin:/Users/node_modules/.bin:/node_modules/.bin:/usr/local/bin' |
|
|
|
// `foo` is a locally installed binary |
|
childProcess.execFileSync('foo', { |
|
env: npmRunPath.env() |
|
}); |
|
``` |
|
|
|
|
|
## API |
|
|
|
### npmRunPath(options?) |
|
|
|
Returns the augmented path string. |
|
|
|
#### options |
|
|
|
Type: `object` |
|
|
|
##### cwd |
|
|
|
Type: `string`<br> |
|
Default: `process.cwd()` |
|
|
|
Working directory. |
|
|
|
##### path |
|
|
|
Type: `string`<br> |
|
Default: [`PATH`](https://github.com/sindresorhus/path-key) |
|
|
|
PATH to be appended.<br> |
|
Set it to an empty string to exclude the default PATH. |
|
|
|
##### execPath |
|
|
|
Type: `string`<br> |
|
Default: `process.execPath` |
|
|
|
Path to the current Node.js executable. Its directory is pushed to the front of PATH. |
|
|
|
This can be either an absolute path or a path relative to the [`cwd` option](#cwd). |
|
|
|
### npmRunPath.env(options?) |
|
|
|
Returns the augmented [`process.env`](https://nodejs.org/api/process.html#process_process_env) object. |
|
|
|
#### options |
|
|
|
Type: `object` |
|
|
|
##### cwd |
|
|
|
Type: `string`<br> |
|
Default: `process.cwd()` |
|
|
|
Working directory. |
|
|
|
##### env |
|
|
|
Type: `Object` |
|
|
|
Accepts an object of environment variables, like `process.env`, and modifies the PATH using the correct [PATH key](https://github.com/sindresorhus/path-key). Use this if you're modifying the PATH for use in the `child_process` options. |
|
|
|
##### execPath |
|
|
|
Type: `string`<br> |
|
Default: `process.execPath` |
|
|
|
Path to the Node.js executable to use in child processes if that is different from the current one. Its directory is pushed to the front of PATH. |
|
|
|
This can be either an absolute path or a path relative to the [`cwd` option](#cwd). |
