WordPress plugin that syncs posts from the database onto the file system, & vice versa.
Download the latest release of the plugin & install it on your WordPress site.
Ensure you're logged in as an admin, then navigate to a page of interest. Once the page loads, open a file browser or SSH agent on your server, & you'll see that page as a .html file in the wp-content/posts directory.
When you save the HTML file, refresh the page in your browser, & you'll see the changes reflected in your browser, & in the WordPress database.
When you save the page in the WordPress admin, refresh the page in your browser, & you'll see the changes reflected in your browser, & in the wp-content/posts directory.
Migration of posts between domains is as simple as copying the wp-content/posts directory from one domain to another. Then, ensuring the posts.json is copied as well & deactivate & reactivate the plugin to ensure the posts' URLs are migrated.
