# split-cmd

> 💦 Split a command into an array or an object

Useful for splitting a command to use with NodeJS' [child process](https://nodejs.org/api/child_process.html) methods, like [spawn](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options), [exec](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback), and [execFile](https://nodejs.org/api/child_process.html#child_process_child_process_execfile_file_args_options_callback), as well with libs like [execa](https://github.com/sindresorhus/execa).

⚡ Just 0.4 KB uncompressed, no external dependencies.

🎯 Version `1.1`+ works with NodeJS, DenoJS and browsers. JavaScript and TypeScript.

## Installation

```bash
npm i split-cmd
```

## Usage

### Splitting into an array

```js
import { split } from 'split-cmd';

const arr = split( 'git commit -m "some message with spaces"' );

console.log( arr ); // [ "git", "commit", "-m", "some message with spaces" ]
```

### Splitting into an object

```js
import { splitToObject } from 'split-cmd';

const obj = splitToObject( 'git commit -m "some message with spaces"' );

console.log( obj.command ); // git
console.log( obj.args ); // [ "commit", "-m", "some message with spaces" ]
```

### Using it with execa

```js
import { splitToObject } from 'split-cmd';
import { execa } from 'execa';

// Executing a single command
const obj = splitToObject( 'echo "I see unicorns"' );
execa( obj.command, obj.args )
    .then( result => console.log( result.stdout ) ) // I see unicorns
    .catch( error => console.log( error ) );

// Executing multiple commands in batch
[
    'echo "I see unicorns"',
    'mkdir foo',
    'touch foo/bar.txt'
]
.map( s => splitToObject( s ) )
.forEach( obj => {
    execa( obj.command, obj.args )
        .then( result => console.log( result.stdout ) )
        .catch( error => console.log( error ) );
} );
```
