The plugin creates zip files containing posts converted to Markdown. A WP-CLI command exists to handle exporting sites with a large amount of content.
<ul>
<li>Move WordPress content to Gatsby-friendly Markdown.</li>
<li>Customize the export! Remap and restructure exported fields.</li>
<li>CLI: Avoid PHP timeouts by using the command line with WP-CLI.</li>
<li>CLI: Export progress bar (great for large sites)!</li>
</ul>
<blockquote>
Reminder: always keep a backup of the WordPress database and files in case your export doesn’t work as expected!

<h3>Working with Gatsby</h3>
If you’re just getting started with Gatsby, we recommend experimenting with a Markdown based Gatsby starter like <a href="https://github.com/tinacms/tina-starter-grande" rel="nofollow ugc">Tina Grande</a>. Installation is as easy as:
<pre><code>git clone https://github.com/tinacms/tina-starter-grande.git

cd tina-starter-grande

yarn install && gatsby develop
</code></pre>
Then copy your exported WordPress Markdown into the <code>content</code> directory or point the wp gatsby-markdown-export command at the content directory.
Want to port your WordPress or HTML theme to Gatsby? Checkout <a href="https://www.gatsbyjs.org/docs/porting-an-html-site-to-gatsby/" rel="nofollow ugc">Porting an HTML Site to Gatsby</a> for tips.
<h3>Command Line Usage</h3>
The command line functionality uses WP-CLI to interact with WordPress. <a href="https://wp-cli.org/#installing" rel="nofollow ugc">WP-CLI is easy to install</a> if you haven’t already.
Once it’s installed, you can export content to a directory like this:
<pre><code>wp gatsby-markdown-export --directory=/example/gatsby-starter/src/content
</code></pre>
All CLI arguments are optional.
