Npm Run Script
---

Installation
---
``bash
npm install npm-run-script --save
`

Motivation
---
child_process doesn't know path of the local-installed npm commands.

`bash
npm install eslint
node -e "require('child_process').exec('eslint').stderr.pipe(process.stderr)"


/bin/sh: eslint: command not found


`

by using execa, this problem can be solved. but, can't inherit the stdout.

`bash
npm install execa
node -e "require('execa').shell('eslint').then((result)=>console.log(result))"


{ stdout: 'eslint [options] file.js [file.js] ...


`

npm-run-script inherits the stdio, and run the command and returns the [child_process.

`bash
node -e "require('npm-run-script')('eslint').once('exit',(code)=>console.log('exit in',code))"


eslint [options] file.js [file.js] [dir]

#

Basic configuration:

...

exit in 0

`

API
---

npmRunScript(command, spawnOptions={stdio:'inherit'}) -> childProcess

run the command as shell comand in childProcess.

`js
import npmRunScript from 'npm-run-script';

const command = 'eslint && exit 59';
const child = npmRunScript(command, { stdio: 'ignore' });// quiet...
child.once('error', (error) => {
console.trace(error);
process.exit(1);
});
child.once('exit', (exitCode) => {
console.trace('exit in', exitCode);
process.exit(exitCode);
});
`
