<p>Configuration files are the <strong>recommended</strong> choice for configuring Puppeteer.
Puppeteer will look up the file tree for any of the following formats:</p>
<ul>
<li><code>.puppeteerrc.cjs</code>,</li>
<li><code>.puppeteerrc.js</code>,</li>
<li><code>.puppeteerrc</code> (YAML/JSON),</li>
<li><code>.puppeteerrc.json</code>,</li>
<li><code>.puppeteerrc.yaml</code>,</li>
<li><code>puppeteer.config.js</code>, and</li>
<li><code>puppeteer.config.cjs</code></li>
</ul>
<p>Puppeteer will also read a <code>puppeteer</code> key from your application&#x27;s
<code>package.json</code>.</p>
<p>See the <a href="/api/puppeteer.configuration"><code>Configuration</code></a> interface for possible
options.</p>

<p>Starting in v19.0.0, Puppeteer stores browsers in <code>~/.cache/puppeteer</code> to
globally cache browsers between installation. This can cause problems if
<code>puppeteer</code> is packed during some build step and moved to a fresh location. The
following configuration can solve this issue (reinstall <code>puppeteer</code> to take
effect):</p>

<p>Along with configuration files, Puppeteer looks for certain
<a href="https://en.wikipedia.org/wiki/Environment_variable" target="_blank" rel="noopener noreferrer">environment variables</a> for
customizing behavior. Environment variables will always override configuration
file options when applicable.</p>
<p>The following options are <em>environment-only</em> options</p>
<ul>
<li><code>HTTP_PROXY</code>, <code>HTTPS_PROXY</code>, <code>NO_PROXY</code> - defines HTTP proxy settings that are
used to download and run the browser.</li>
