<p>The SQLite plugin is a community, feature plugin. The intent is to allow testing an SQLite integration with WordPress and gather feedback, with the goal of eventually landing it in WordPress core.</p>
<p>This feature plugin includes code from the PHPMyAdmin project (specifically parts of the PHPMyAdmin/sql-parser library), licensed under the GPL v2 or later. More info on the PHPMyAdmin/sql-parser library can be found on <a href="https://github.com/phpmyadmin/sql-parser" rel="nofollow ugc">GitHub</a>.</p>


SQLite Database Integration



Installed version 2.0



Activated



Message: "All checks completed successfully, your site can use an SQLite database. You can proceed with the installation."



Screen with text and button. Ok, I can go back by just deactivating this plugin! Great!



Clicked button "Install SQLite database"



"PDO Driver for SQLite is missing" alone on an blank page, wheverer I go



Stuck. My somewhat "well crafted" and sophisticated testing site gone away, it seemed. 




Why could this plugin not check the availability of this driver before presenting a clickable button, or even proceeding?



Since I'm knowledgable enough to delete the ´wp-content/db.php´ file I was soon back to start, so I don't need help.



Others, if less knowledable in WP, should be warned and stay away until proper tests can be made before proceeding. On screen instructions on how to manually disable it in an emergency should also be given.


Possibly worst UX trap I have ever seen


I used it to spin up a test site in CI, it's just elegant and brings WP closer to Static when we need it. There's a place for SQLite simplicity in some WP workflows. Loved it!


Excellent!


Thank you dev team for providing this plugin !


Great Plugin! Makes WP so fast!


Ok, so in terms of doing what it says in the tin, for me it looks great. I've set up 20 - 30 instances, it runs my core plugins and has a footprint of ~ 105M when running with a default setup. Seems to be at least as fast as the MySQL instances sat next to them.



Here's the problem tho'. It would seem I can't actually convert any existing sites over to run on these instances without a lot of manual work. (I say this after reading the experiences of some others who claim to have tried).



Are there any relatively automatic tools and/or documentation that I might have missed when it comes to migrating a MySQL instance over to SqLite (and back, in the event of a problem), or at least a Roadmap of if / when such tools or plugins might become available?



A roadmap or estimation might at least (if it's a long way away) prompt someone to get on and do it?


Great, seems only one step away ...
