<p>In the root of your package directory, create a <strong>composer.json</strong> file. This file
defines metadata about your package and its dependencies.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">composer</span> <span class="pre">init</span></code> command helps you create it.</p>

<section id="package-name">
<h3><a class="toc-backref" href="#id3">Package Name</a><a class="headerlink" href="#package-name" title="Permalink to this headline"></a></h3>
<p>The <code class="docutils literal notranslate"><span class="pre">name</span></code> field is important here. Package names are generally written in the
format “vendor-name/package-name” with all lowercase. Here is a common example:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">your-vendor-name</span></code>: The name that identifies the vendor (creator of the package),
such as your name or your organization.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">your-package-name</span></code>: The name of the package you are creating.</p></li>
</ul>
<p>Thus, it is important to make the name unique to distinguish it from other packages.
Uniqueness is especially important when publishing.</p>
</section>
<section id="namespace">
<h3><a class="toc-backref" href="#id4">Namespace</a><a class="headerlink" href="#namespace" title="Permalink to this headline"></a></h3>
<p>The package name then determines the vendor namespace in <code class="docutils literal notranslate"><span class="pre">autoload.psr4</span></code>.</p>
<p>If your package name is <code class="docutils literal notranslate"><span class="pre">your-vendor/your-package</span></code>, the vendor namespace must
be <code class="docutils literal notranslate"><span class="pre">YourVendor</span></code>. So you would write like the following:</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="s2">&quot;autoload&quot;</span><span class="o">:</span> <span class="p">{</span>
<span class="s2">&quot;psr-4&quot;</span><span class="o">:</span> <span class="p">{</span>
<span class="s2">&quot;YourVendor</span><span class="se">\\</span><span class="s2">YourPackage</span><span class="se">\\</span><span class="s2">&quot;</span><span class="o">:</span> <span class="s2">&quot;src/&quot;</span>
<span class="p">}</span>
<span class="p">},</span>
</pre></div>

<p>This setting instructs Composer to autoload the source code for your package.</p>

<p>There are many tools that help ensure quality code. So you should use them.
You can easily install and configure such tools with
<a class="reference external" href="https://github.com/codeigniter4/devkit">CodeIgniter DevKit</a>.</p>
<section id="installing-devkit">
<h3><a class="toc-backref" href="#id7">Installing DevKit</a><a class="headerlink" href="#installing-devkit" title="Permalink to this headline"></a></h3>
<p>In the root of your package directory, run the following commands:</p>
<div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="go">composer config minimum-stability dev</span>
<span class="go">composer config prefer-stable true</span>
<span class="go">composer require --dev codeigniter4/devkit</span>

</div>
<p>The DevKit installs various Composer packages that helps your development, and
installs templates for them in <strong>vendor/codeigniter4/devkit/src/Template</strong>.
Copy the files in it to your project root folder, and edit them for your needs.</p>
