Day 3: JS Scripts 🚀

I like JavaScript and I don't like bash! And today I'd like to share with you a tool that allows me to do less of the latter: zx.

There are several ways to install it, with Deno you could do it like so:

deno install --global -A npm:zx 

Create a script, e.g. list.ts:

#!/usr/bin/env zx import { $ } from 'npm:zx' const list = await $`ls` console.log(list) 

Allow execution as a script:

chmod +x list.ts 

And, finally, run it:

./list.ts 

Isn't it awesome?! You can use any command available on your machine, check this example out:

#!/usr/bin/env zx  await $`cat package.json | grep name` const branch = await $`git branch --show-current` await $`dep deploy --branch=${branch}` await Promise.all([ $`sleep 1; echo 1`, $`sleep 2; echo 2`, $`sleep 3; echo 3`, ]) const name = 'foo bar' await $`mkdir /tmp/${name}` 

And, as any other package, you could use zx as a library. Imagine all the cool things you could build!

Liked the content and would love to have more of it all year long?
