Development Mode for Jetpack

How can I see a full list of modules I can activate in Jetpack with Development Mode enabled?

On your website with both Jetpack and Development Mode for Jetpack enabled, go to example.com/wp-admin/admin.php?page=jetpack_modules, replacing example.com with your website URL.

On that page, you will see a complete list of modules available for activation with Development Mode.

Props to Ben Gillbanks for the tip.

You sound like a Jetpack hater! Is that true?

That couldn’t be further from the truth.

I support Jetpack feature(s) in every single one of my themes. An odd thing for a “hater” to do, isn’t it?

Many of the Jetpack features I support in my themes are derived from the aforementioned, self-contained modules. Jetpack Development Mode makes it easier to develop by eliminating unnecessary tasks.

Where is the settings page?

There isn’t one!

Activate this plugin if you want to enable Jetpack Development Mode. Deactivate if you don’t.

Can’t I get the same effect by adding a line to my theme’s functions.php file, or plopping this into an mu-plugin?

You sure can! Here’s the line you would need to add:

add_filter( 'jetpack_development_mode', '__return_true' );

Activating a plugin like this is just one approach. I prefer it, and you may prefer another.

To each their own.

How does this plugin differ from other plugins in the repository that do the same thing?

One comparable plugin I could find hasn’t been updated in over 2 years. While such a simple, one-line plugin needs minimal maintenance, it would be nice if it was periodically tested with the latest versions of Jetpack and WordPress to ensure smooth operation.

I plan on doing that, since I use Jetpack Development Mode very often.

That other plugin also ships with translations and includes a textdomain loading function. My plugin does not.

Finally, my plugin uses a slightly different, more defensive coding style that ensures Jetpack is active and loaded, prior to running any pertinent code.

Not huge differences, but I do want to note the differentiation.
