Today's npm package is child-process-ext

When creating CLI tools, you might wanna use other CLI tools and not have the luxury of npm package around those tools.

In such cases, you would need to create a child process with specific CLI command and get the result from that process.

And to create child process, we have node.js's spawn function

Currently spawn functions are not promisified and today's package child-process-ext will let you do the promisified work on spawned processes.

Here's how to use it:

const spawn = require('child-process-ext/spawn');

const proc = spawn('ls');

proc.then(op => console.log(op.stdoutBuffer.toString()))

and generates following output:

Stay tuned for tomorrow's package of the Day.
