Repository Summary (README)
Preview#!/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}`
Bash is great, but when it comes to writing more complex scripts,
many people prefer a more convenient programming language.
JavaScript is a perfect choice, but the Node.js standard library
requires additional hassle before using. No compromise, take the best of both. The zx package provides
useful cross-platform wrappers around child_process, escapes arguments and
gives sensible defaults.
Install
npm install zx
All setup options: zx/setup. See also zx@lite.
