<p>Bash is great, but when it comes to writing scripts, people usually choose a
more convenient programming language. JavaScript is a perfect choice, but
standard Node.js library requires additional hassle before using. The <code>zx</code>
package provides useful wrappers around <code>child_process</code>, escapes arguments and
gives sensible defaults.</p>
<h2 id="install"><a class="header" href="#install">Install</a></h2>
<pre><code class="language-bash">npm i -g zx
</code></pre>
<h3 id="requirement"><a class="header" href="#requirement">Requirement</a></h3>
<p>Node.js &gt;= 14.8.0</p>
<h2 id="documentation"><a class="header" href="#documentation">Documentation</a></h2>
<p>Write your scripts in a file with <code>.mjs</code> extension in order to be able to use
<code>await</code> on top level. If you prefer the <code>.js</code> extension, wrap your scripts in
something like <code>void async function () {...}()</code>.
Add the following shebang to the beginning of your <code>zx</code> scripts:</p>
<pre><code class="language-bash">#!/usr/bin/env zx
</code></pre>
<p>Now you will be able to run your script like so:</p>
<pre><code class="language-bash">chmod +x ./script.mjs
./script.mjs
</code></pre>
<p>Or via the <code>zx</code> executable:</p>
<pre><code class="language-bash">zx ./script.mjs
</code></pre>
<p>All functions (<code>$</code>, <code>cd</code>, <code>fetch</code>, etc) are available straight away without any
imports.</p>
<h3 id="command"><a class="header" href="#command"><code>$`command`</code></a></h3>
<p>Executes a given string using the <code>spawn</code> function from the <code>child_process</code>
package and returns <code>ProcessPromise&lt;ProcessOutput&gt;</code>.
Everything passed through <code>${...}</code> will be automatically escaped and quoted.</p>
<pre><code class="language-js">let name = "foo &amp; bar";
await $`mkdir ${name}`;
</code></pre>
<p><strong>There is no need to add extra quotes.</strong> Read more about it in
<a href="docs/quotes.html">quotes</a>.
You can pass an array of arguments if needed:</p>
<pre><code class="language-js">let flags = ["--oneline", "--decorate", "--color"];
await $`git log ${flags}`;
</code></pre>
<p>If the executed program returns a non-zero exit code, <code>ProcessOutput</code> will be
thrown.</p>
<pre><code class="language-js">try {
await $`exit 1`;
} catch (p) {
console.log(`Exit code: ${p.exitCode}`);
console.log(`Error: ${p.stderr}`);
}
</code></pre>

<p>In <a href="https://nodejs.org/api/esm.html">ESM</a> modules, Node.js does not provide

modules, the <code>require()</code> function is not defined. The <code>zx</code> provides <code>require()</code>
function, so it can be used with imports in <code>.mjs</code> files (when using <code>zx</code>

<p>If array of values passed as argument to <code>$</code>, items of the array will be escaped
individually and concatenated via space.
Example:</p>

await $`tar cz ${files}`
</code></pre>
<h4 id="importing-from-other-scripts"><a class="header" href="#importing-from-other-scripts">Importing from other scripts</a></h4>
<p>It is possible to make use of <code>$</code> and other functions via explicit imports:</p>
<pre><code class="language-js">#!/usr/bin/env node
import { $ } from "zx";
await $`date`;
</code></pre>
<h4 id="scripts-without-extensions"><a class="header" href="#scripts-without-extensions">Scripts without extensions</a></h4>
<p>If script does not have a file extension (like <code>.git/hooks/pre-commit</code>), zx
assumes that it is an
<a href="https://nodejs.org/api/modules.html#modules_module_createrequire_filename">ESM</a>

<h4 id="markdown-scripts"><a class="header" href="#markdown-scripts">Markdown scripts</a></h4>

<p>The <code>zx</code> can compile <code>.ts</code> scripts to <code>.mjs</code> and execute them.</p>
